Answer 1

Answer:

$\huge\mathfrak\red{ANSWER}$

•vεgεtαtive propαgαtion any form of asexual reproduction occurring in plants in which a new plant grows from a fragment of the parent plant or grows from a specialized reproductive structure (such as a stolon, rhizome, tuber, corm, or bulb).

$methods include:$

• rooting of cuttings, • layering or marcotting, • grafting, • micropropagation.

$αdvαηтagεs$

the new plants contain the genetic material of only one parent, so they are essentially clones of the parent plant.

This can also help to maintain consistent quality and taste in products made from plants or crops.

Answer 2

$\textbf{Answer:-}$

What is Vegetative Propagation?

• Vegetative propagation is an asexual method of plant reproduction that occurs in its leaves, roots and stem. This can occur through fragmentation and regeneration of specific vegetative parts of plants.

Write the methods involved in it.

Cutting:-

• In this, a part of a plant, specifically a stem or leaf is cut and planted in the soil. These cuttings are sometimes treated with hormones to induce root development. The new plant is formed from the adventitious roots developing from the cutting.

Grafting:-

• In this, the cutting from some other plant is attached to the stem of plant rooted in the ground. The tissues of the graft become integrated with the tissues of the rooted plant and develop as a single plant over time.

Layering:-

• In this, the stem of the plant is bent to the ground and covered with soil. Adventitious roots emerge from the plant parts covered with the soil. This attached stem with developing roots is known as a layer.

Tissue Culture:-

• In this, the plant cells from different parts of a plant are cultured in the laboratory to develop a new plant. This technique is helpful in increasing the number of rare and endangered plant species that are unable to grow under natural conditions.

Advantages of vegetative propagation:-

• Quicker and more certain.

• Produces identical quality as the parent.

• Plants that do not have viable seed, can be reproduced.

• Flowers produced are of superior quality.

• Desirable character of fruit can be maintained.
