The roots that originate from the base of the stem are:
1 Primary roots
2 Prop roots
3 Lateral roots
4 Fibrous roots
Explanation:
: - Fibrous roots originate from the base of the stem. It is seen in the monocots. For eg. Wheat, Rice etc. They perform functions like absorbing water and minerals from the soil and also provide support to the plant. - Primary root originates at the germination stage from the radicle of the seed. - Prop root is a modification of adventitious roots. Usually Adventitious roots develop from the stem and leaves. The prop root provides additional support to the plants because they have very strong roots. E.g- Banyan tree, Mangroves etc.

Assertion (A): Tap roots of sweet potato become swollen to perform functions other than absorption and conduction of water Reason (R) : Roots in some plants are modified for storage of food. The correct answer is:
1 Both (A) and (R) are true (R) is the correct explanation of \((\mathrm{A})\)
2 Both (A) and (R) are true but (R) is not the correct explanation of \((\mathrm{A})\)
3 (A) Is true but (R) is false
4 (A) Is false but (R) is true
Explanation:
D Root modifications are the permanent change in the structure which are caused so that the plant can be able to withstand and adjust to the environment. Storage roots, such as carrots beets and sweet potatoes are examples of roots that are specially modified for storage of starch and water they usually grow underground as protection from plant eating animals.

, -Taproot- When roots are arises from radical is called Tap root. , - Adventitious root- The roots arise from parts of the plant other than the radical and are called adventitious roots. For examples:- Sweet potato. , - Stem- Each eye represents a node, bearing one or more buds subtended by a leaf scar (scale leaf). For example: Potato. , - Fibrous root- It is usually formed by thin, moderately branching roots growing from the stem. For example:- Grass, wheat, rice, marigold, white clover, maize, banana, millet, bamboo and onion.

Thigmotropism is best seen in
1 tendrils
2 leaf apex
3 root apex
4 stem apex
Explanation:
A Thigmotropism is best seen in tendrils. It is a movement due to contact with a foreign body. It is most conspicuous in tendrils, which coil around support and help the plant in climbing. It is best observed in tendrils and twining plants. It is also known as haptotropism. It is the movement or change in orientation of a plant's growth as a reaction to touch. Example of tendrils of sweet pea coiling around a support.
