1) absorb oxygen and release carbon dioxide
2) absorb carbon dioxide and release oxygen
3) absorb water and release oxygen
4) absorb water vapor and release carbon dioxide
Explanation.
Root cells are living, they breathe, absorbing oxygen and releasing carbon dioxide.
Answer: 1
1) protective
2) educational
3) support
4) conductive
Explanation.
Mechanical tissues provide strength to plant organs. They form a frame that supports all plant organs, resisting their fracture, compression, and rupture. The main characteristics of the structure of mechanical tissues, ensuring their strength and elasticity, are the powerful thickening and lignification of their membranes, close closure between cells, and the absence of perforations in the cell walls.
Mechanical tissues are most developed in the stem, where they are represented by bast and wood fibers. In roots, mechanical tissue is concentrated in the center of the organ.
Answer: 3

Good afternoon. option 5 of this task is also suitable, since the integumentary tissues carry out gas exchange and transperation, carrying inorganic substances through the stomata.
Natalia Evgenievna Bashtannik
this function is called gas exchange
The root of most existing plants cannot perform the function
1) breathing
2) carrying substances
3) storage of organic substances
4) photosynthesis
Explanation.
Functions of the root. The root is the axial organ of the plant, serving to strengthen the plant in the substrate and absorb water and dissolved minerals from it. In addition, various organic substances (growth hormones, alkaloids, etc.) are synthesized in the root, which then move through the xylem vessels to other plant organs or remain in the root itself. It is often a storage site for reserve nutrients.
But the root does not participate in the process of photosynthesis (in most plants, but there are exceptions)
Answer: 4
1) hydrotropism
2) phototropism
3) geotropism
4) chemotropism
Explanation.
Chemotropism causes plant movement under the influence chemical compounds. Phototropism is the ability of a plant organ to bend under the influence of light. Hydrotropism is the ability of growing plant organs, especially roots, to bend in the direction from a less humid environment to a more humid one.
The organs of hawthorn (a) and grapes (b), indicated in the figures with a question mark, develop from identical embryonic rudiments. What are the names and as a result of what evolutionary process were such organs formed that have a similar structure and origin? Which method of studying evolution involves the presence of such organs? Name which organ of each plant they are a modification of and what function they perform.
Explanation.
1. A - hawthorn thorn; B - grape mustache - Homologous organs - organs that are similar to each other in origin and structure, but perform different functions. Their appearance is the result of divergence.
2. The method of studying evolution is classified as comparative anatomical (comparative morphological).
3. A - hawthorn thorn; B - grape mustache is a modification of the shoot.
The function of hawthorn thorns is to protect against being eaten by animals.
The function of the grapevine is additional support and fastening of the plant.
Note.
Divergence is the divergence of characters and properties in initially close groups of organisms during evolution.
Attention!
In the original source, the letter A refers to barberry, but barberry has a thorn - this is a modified leaf. And the drawing is represented by hawthorn - barberry develops normal leaves (several) on short shoots, and thorns instead of leaves on elongated shoots.
1) reproduction by spores
2) differentiation into organs and tissues
3) fertilization, which occurs outside the aquatic environment
4) autotrophic method of nutrition
5) cross-pollination by insects
6) the predominance of woody forms among them
Explanation.
General characteristics of higher spore plants.
1. The presence of multicellular antheridia (male reproductive organs) and archegonia ( female organs sexual reproduction) and multicellular sporangia (asexual reproduction).
2. Alternation of diploid (asexual generation - sporophyte) and haploid phases (sexual generation - gametophyte) in life cycle; In most organisms, gametophytes are dioecious.
3. Plants that have an embryo (a feature that distinguishes them from algae) and reproduce by spores.
4. Differentiated sporophyte (organs and tissues).
Correct answer: reproduction by spores, differentiation into organs and tissues, autotrophs. The autotrophic mode of nutrition is characteristic of all plants, but in these answer options it characterizes the similarity of mosses and ferns. Under the numbers 3, 5, 6 are signs characteristic of seed plants.
Answer: 124.
Answer: 124
Natalia Evgenievna Bashtannik (Novocherkassk)
Liver mosses - equipped with stems and leaves, devoid of any veins and arranged in two or three rows; those on the side facing the soil are scaly and of a completely different shape than the rest. The upper leaves, usually arranged in two rows, have two lobes, of which one small one takes a special shape and is bent downwards.
Leafy mosses are always divided into stems and leaves. The leaves are arranged spirally and collected at the apex in the form of a bud.
Guest 07.05.2013 20:20
fertilization of ferns and bryophytes requires water
Natalia Evgenievna Bashtannik
yes, they need water. But this option is not offered in the answer.
Svetlana Korshunova 17.06.2017 00:08
Please explain point 3 of the note: “plants with an embryo.”
Natalia Evgenievna Bashtannik
U higher plants a zygote (a diploid cell resulting from the fusion of two physiologically opposite haploid cells - gametes) turns into an embryo.
The process of embryo formation is known as embryogenesis. The embryo is a more or less dissected miniature sporophyte, before rapid growth(in seed plants - germination) being in a state of relative dormancy for some time. Its parts consist of cells with meristematic activity. With the beginning active growth the process of organogenesis begins in the embryo, i.e. development of vegetative organs, already established in the embryo.
The embryo of seed plants is located in the seed.
What are distinctive features higher plants compared to lower ones?
Explanation.
1) Higher plants are multicellular, lower plants are unicellular and multicellular.
2) Higher ones have tissues and organs. The body of the lower ones is the thallus.
3) Chlorophyll is contained in chloroplasts, in lower ones - in the chromatophore.
Higher plants form specialized organs in which gametes mature.
Note.
Vlad Kuznetsov 16.01.2018 08:11
A different answer was given to a similar question https://site/problem?id=17380; it is not very clear which one is considered more correct (since plants are divided only into lower and higher, the question about the characteristics of one of the taxa is the same as the question is how this taxon differs from another.)
Natalia Evgenievna Bashtannik
Both questions and their answers are correct. If the question is about differences, it is recommended to give the answer by comparing one with the other.
List the characteristics of higher plants.
Explanation.
Higher plants have organs and tissues in their bodies. In the development cycle there is an alternation of sexual and asexual generations. Higher plants form specialized organs in which gametes mature. Higher plants are adapted to life both in aquatic environments and on land.
Note.
Higher plants include bryophytes and vascular plants (ferns, lycophytes, gymnosperms and angiosperms).
Armenak Agbalyan 13.06.2018 18:56
Can we say that only they have seeds, that only they have tree-like forms?
Natalia Evgenievna Bashtannik
No, because higher plants include And bryophytes and vascular plants (ferns, lycophytes, gymnosperms and angiosperms).
2. Angiosperms
Write down the selected numbers in the table under the corresponding letters.
| A | B | IN | G | D | E |
Explanation.
1. Green algae: B. a cell center may be present in the cells; G. form motile gametes; D. zygote divides by meiosis
2. Angiosperms: A. cells contain a variety of plastids; B. organs and tissues are well developed; E. sporophyte predominates in the life cycle
Note
Plastids are colorless or colored bodies in the protoplasm of plant cells, representing complex system internal membranes and performing various functions.
The cells of higher plants contain a variety of plastids: colorless plastids are called leucoplasts, variously colored ones are called chromoplasts, and green ones are called chloroplasts. The cells of higher plants usually contain from 10 to 200 plastids 3-10 microns in size, most often having the shape of a biconvex lens.
U green algae- green plastids called chromatophores- can have star-shaped, ribbon-shaped, mesh and other shapes.
In lower fungi - chytridiomycetes - and in higher plants there is no CELL CENTER. As it turned out, in algae, in human cells and in most animals, the presence of a cell center is necessary for the processes of mitosis and meiosis.
What characteristics are common to bryophytes and pteridophytes? Choose three correct answers out of six and write down the numbers under which they are indicated.
1) depend on water for reproduction
2) have conductive fabrics
3) have roots and shoots with leaves
4) have vegetative organs
5) form seeds
6) reproduce by spores
Explanation.
Under the numbers 1, 4, 6 are signs of similarity between bryophytes and pteridophytes.
Number 2 is a sign of pteridophytes (conductive tissue is well developed in the stem, between the bundles of which the cells of the main parenchymal tissue are located), and moss-like ones are low-growing perennials herbaceous plants- in most of them the body is divided into stems and leaves, but there are also thallous forms; vegetative organs are formed by assimilation, conduction, storage and integumentary tissues. However, unlike other higher plants, bryophytes lack true vessels and mechanical tissues.
Number 3 means that mossy roots do not have roots; they have an attachment organ - rhizoids. The body of the fern consists of leaf blades, a petiole, a modified shoot and roots (vegetative and adventitious). The leaves of a fern are called fronds.
Under the number 5, both bryophytes and pteridophytes reproduce by spores; the seeds are gymnosperms and angiosperms.
