1. Reproduction in Plants

2. Reproduction in Plants
For plants to survive, they need to reproduce.
Two types of plants reproduction:
Sexual
Asexual

3. Sexual Reproduction
Sexual reproduction involves creation of a new individual produced by the combining features or genes from two parents.
Sexual reproduction in plants occurs through the medium of flowers.
The flower structure is made up of pollen producing male part known as stamen, and female part called as pistil that contains the ovary and eggs.

5. Sexual Reproduction
Pollination is the process that starts the sexual reproducing mechanism.
The petals play a vital role in attracting insects to the flowers that carry pollen from one plant to another.
Pollination results in production of seeds, and almost all plants are reproduced through this mechanism.

7. Asexual Reproduction
Plants are made up of cells and tissues that carry within them the ability to regenerate the entire plant structure called as totipotency, which ensures offspring completely identical to the parent.
This means any part of the plant: leaves, stems, or roots are capable of reproducing a new individual plant under suitable conditions.

8. Asexual Reproduction - Stems
Stems is the most common example of an asexual reproduction in plants.
They shoot from a leaf node, and instead of developing into leaves, develop into stems with very few leaves.
These stems produce roots that go down into the soil, while shooting new leaves above the ground.
Examples: Strawberry.

9. Asexual Reproduction - Leaves
Leaves like that of a cactus are all capable of producing plantlets from the leaves.
The plantlets are produced on the leaf margins, that fall to the ground and take root, and mature into individual plants.
Examples: Kalanchoe and the aquatic plant .
Amazing thing: the leaf that reproduces may not always be attached to the plant. A fallen leaf is also capable of producing leaflets as long as the cells and tissues are alive.
