Answers
Explanation:
37. Answer.
Examples: Wheat, paddy, cabbage, grass, coriander, etc. Shrubs: These are bushy and medium- sized plants and they are somewhat bigger than herbs. Their branches start from just above the ground. Examples: Lemon, Coriander, Henna, Rose, etc.
38. Answer
root, in botany, that part of a vascular plant normally underground. Its primary functions are anchorage of the plant, absorption of water and dissolved minerals and conduction of these to the stem, and storage of reserve foods.
39. Answer
Stems have four main functions which are: Support for and the elevation of leaves, flowers and fruits. The stems keep the leaves in the light and provide a place for the plant to keep its flowers and fruits. Transport of fluids between the roots and the shoots in the xylem and phloem
40. Answer
The term leaf refers to the organ that forms the main lateral appendage on the stem of vascular plants
41. Answer
The main function of flowers is to produce fruits and seeds.The main parts of a flower are: sepals, petals, stamen and pistil.
42. Answer
Photosynthesis is important to plants because it allows them to make glucose, which is needed to make energy and cellular structures.
43. Answer
The taproot is the differentiated primary root that is thick and grows straight down deep into the soil. ... Fibrous roots form a network of roots near the surface of the soil where they absorb minerals and water. They also hold several soil particles together and thus help to prevent or reduce soil erosion.... draw it your self...
44. Answer
Stamen: The pollen producing part of a flower, usually with a slender filament supporting the anther. Anther: The part of the stamen where pollen is produced. Pistil: The ovule producing part of a flower. The ovary often supports a long style, topped by a stigma. ... Stigma: The part of the pistil where pollen germinates.
45. Answer
➡Nature of roots and venation in leaves of a plant is related. If the root is tap root then the plant has reticulated venation. If the root is fibrous root then the plant has parallel venation.so in this way the root and venation in leaves of plant are related
I hope this is really useful to you...
Answer:
Ans 37 - Any plant with leaves, seeds, or flowers used for flavouring, food, medicine, or perfume is called herb . for example - wheat , rice etc .
A woody plant which is smaller than a tree and has several main stems arising at or near the ground is called shrub. For example - Lemon, Tulsi etc .
A long-lived woody plant that has a single usually tall main stem with few or no branches on its lower part is called tree . For example - Mango tree, Neem tree etc.
Ans 38 - Root :- It is the part of a plant which attaches it to the ground or to a support, typically underground, conveying water and nourishment to the rest of the plant via numerous branches and fibres.
Roots are used for :-
1) absorption of water and inorganic nutrients
2) anchoring of the plant body to the ground, and supporting it 3) storage of food and nutrients
4) trans locating water and minerals to the stem.
Ans 39 - A stem is one of two main structural axes of a vascular plant, the other being the root. It supports leaves, flowers and fruits, transports water and dissolved substances between the roots and the shoots in the xylem and phloem, stores nutrients, and produces new living tissue.
The primary functions of the stem are to support the leaves; to conduct water and minerals to the leaves, where they can be converted into usable products by photosynthesis; and to transport these products from the leaves to other parts of the plant, including the roots.
Ans 40 - Leaf is a flattened structure of a higher plant, typically green and blade-like, that is attached to a stem directly or via a stalk. Leaves are the main organs of photosynthesis and transpiration.

Ans 41 - The primary purpose of the flower is reproduction. Since the flowers are the reproductive organs of the plant, they mediate the joining of the sperm, contained within pollen, to the ovules — contained in the ovary. Pollination is the movement of pollen from the anthers to the stigma.

Ans 42- It is the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.
Photosynthesis is important to plants because it allows them to make glucose, which is needed to make energy and cellular structures.
Ans 43 - Tap root :-It is a straight tapering root growing vertically downwards and forming the centre from which subsidiary rootlets spring.
Fibrous root :- A fibrous root system is the opposite of a taproot system. It is usually formed by thin, moderately branching roots growing from the stem

Ans 44 - a) Stamen - the male fertilizing organ of a flower, typically consisting of a pollen-containing anther and a filament.

b) Pistil - the female organs of a flower, comprising the stigma, style, and ovary.

Ans 45 - Venation - the arrangement of veins in a leaf or in an insect's wing.
There are two types of venation, reticulate and parallel venation.
