respiration takes place in the plants root?
the stalk of the leaves is called petiole?
leaf is the main shoot of the plant?
Answers
Answer:
1) As with photosynthesis, plants get oxygen from the air through the stomata. Respiration takes place in the mitochondria of the cell in the presence of oxygen, which is called "aerobic respiration". ... Roots need oxygen: As mentioned above, roots respire too!
2) The petiole is a stalk that attaches a leaf to the plant stem. In petiolate leaves, the leaf stalk (petiole) may be long, as in the leaves of celery and rhubarb, short or completely absent, in which case the blade attaches directly to the stem and is said to be sessile.
3) shoots consist of stems including their appendages, the leaves and lateral buds, flowering stems and flower buds. The new growth from seed germination that grows upward is a shoot where leaves will develop. ... Some plants (e.g. bracken) produce toxins that make their shoots inedible or less palatable.

Explanation:
That part of the plant which is below the ground (in the soil), is called root.
The main functions of root are:
(1) Roots anchor the plant to the soil. It means that root fix the plant firmly to the soil or ground. This prevents the plant from being pulled out easily or blown away by the wind.
(2) Roots absorb water and mineral from the soil. These are needed for the manufacture of food by plant leaves.
(3) Roots that help in holding the soil together. In this way, roots prevent the soil from being blown away by wind or washed away by water and help in the conversation of soil.
The stem of a plant has a large number of narrow tubes inside it.
(1) One type of tubes in the stem carry water and dissolved minerals from the roots to the leaves and other parts. The leaves of the plant make food by photosynthesis.
(2) Another types of tubes present in the stem carry food from the leaves to all other parts of the plants, including roots.
Leaf
The leaf is a thin, broad, flat and green part of a plant which is attached to the stem or branch.
A plant has large number of leaves. Leaves of different plants have different shapes and sizes, but all of them have same basic structure.
(1) A leaf consists mainly of two parts lamina and petiole.
Lamina is commonly as leaf blade and petiole is commonly known as leaf stalk.
The broad green part of the leaf is called lamina.
The thin stalk with which leaf is attached to the stem is called “petiole”.
