PLANT REPRODUCTIO N Presented by: Syahrul Bariyah Anji

Why plants need to reproduce?

Plant need to reproduce in order to continue to exist. If plants do not reproduce, humans will not get food supply. Animals that feed on plants will also not survive

PLANT REPRODUCTION

Two types… 1. Sexual 2. Asexual

Sexual plant reproduction …

SEXUAL REPRODUCTION… 1. Pollinatio n 2. Fertilisati on

…lead to creation of new seeds that grow into new plants.

POLLINATION? ?

POLLINATI ON The transfer of pollen from the anther to the stigma

Human and most animals are either male or female… How about plants?

Pollination begins in the flower…

4. WATER Plant pollinated by water…Water lily

Why do pollination agents are required in the process of pollination?

• Plants cannot move,. • They need agents to help them in the transfer of the pollen from the anther to the stigma.

Types of pollinati on:-

Selfpollination

Crosspollination

Types of pollination Self-pollination • Only one plants is involved. • Involves one or two flowers. • The young plants have the same characteristic as the parent plant.

Cross-pollination

• Two plants of the same species are involved. • Involves two flowers. • The young plants may look different from the parent plant.

Advantages of crosspollination… 1. Enables genetic materials 2. Results in new from two different plants of the same species to combine. The young plant inherits characteristics from both parent plants.

varieties; may inherit the good characteristics from both parents.
