2. Give the important functions of the following
(a) stem
(b) leaf
(c) flower
(d) root
Answers
Explanation:
a)stem
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.
b) leaf
The main function of a leaf is to produce food for the plant by photosynthesis. Chlorophyll, the substance that gives plants their characteristic green colour, absorbs light energy. The internal structure of the leaf is protected by the leaf epidermis, which is continuous with the stem epidermis.
c)flower
The primary purpose of a flower is reproduction. Since the flowers are the reproductive organs of 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.
d)root
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.
Answer:
The main functions of
Explanation:
STEM:-
The primary functions of the stem are to support the leaves
To conduct water and minerals to the leaves.
Leaf:-
Leaves are the primary way plants interact with the atmosphere and take care of their basic needs.
Plants don’t eat food (heterotrophic)—they make it (autotrophic) by taking atmospheric CO2, water from the soil, and energy from light to make simple sugars. Hence leaves also participate in the photosynthesis.
Flower:-
Flower is the most decorative and beautiful parts of plants.
The primary purpose of a flower is reproduction.
the flowers are the reproductive organs of plant, they mediate the joining of the sperm, contained within pollen, to the ovules — contained in the ovary.
Roots:- 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.
