Question

What is reproduction in plant and how many type ​

Answer 1

# asexual reproduction (the production of organism from a single parent without the involvement of sex cell is called a sexual reproduction)

#there are 6 types of asexual reproduction

fission ( the unicellular organism splits into two or more organism)

#budding( small part of organism ofvpa of parent organise grow out as a bud and detaches)

#spore formation (the parents plant produce hundred of microscopic reproductive units called Spores and germinate as a new organism)

# regeneration (the process of getting back up full organised from its body part is called regeneration)

#fragmentation( the breaking up of body of a simple multicellular organism into two or more pieces on maturing each of them was grow to form a complete new organism)

# vegetative propagation (new planted obtained from the part of old plant like steam root and leaves without the help of any Road productive organ)

Answer 2

A mode of reproduction determines the genetic constitution of a plant and helps to understand its characteristics. If we look at a plant, we notice that it consists of different parts. The parts of a plant can be categorized as vegetative parts, which include leaves, roots and stem, and reproductive parts, which include flowers. A flower may either possess male parts or female parts or both male and female parts. Flowers perform the reproductive function in plants. When the male parts and the female parts are brought in contact, the gametes fuse to produce fruits that bear seeds. The seeds inside the fruits germinate to produce new plants. However, the vegetative parts of the plants are also capable of giving rise to new plants.

The modes of plant reproduction can be majorly classified as:

Asexual mode of reproduction

Vegetative Propagation –

A new plants are developed from a portion of the main plant ‘s body. It can be reproduced both naturally as well as by the artificial method of vegetative propagation. For example- Onion bulbs are produced natural propagation. Rose and banana plants are produced are artificial methods of propagation.

Budding –

In this mode of asexual reproduction new plants grow from an outgrowth or bud in the plant body.

Fragmentation –

A new plants are developed from fragments of the parent plant.

Apomixis –

it is the type of asexual reproduction in which seeds are formed and the embryo is developed without the fusion of male and female gametes. Citrus trees commonly use this method of asexual reproduction by using their seeds.

Sexual mode of reproduction

Pollination

A process in which the pollen grains are transferred across the anther to the stigma of the same flower or to flowers different plants. There are two types of pollination- self-pollination, and cross-pollination.

Zygote formation

After the transfer of pollen grains, the male gamete is transferred down through the style of the pistil to the ovary where the male gamete is fused with female gamete to form a zygote.

Fruit and seed formation

After fertilization, a formed zygote is developed into an embryo. The ovary develops into fruit and ovules into seeds.
