Reproduction in plants

State the function(s) of an Anther?

• contains pollen sac that contains the pollen grains (male reproductive cells)

• produces and releases pollen

State the function(s) of a Filament?

• supports the anther

State the function(s) of a Stigma?

• receives pollen grains

State the function(s) of a Style?

• connects the stigma to the ovary

State the function(s) of an Ovary?

• protects the ovule

• becomes a fruit after fertilisation takes place.

State the function(s) of an Ovule?

• contains the egg cell (female reproductive cell)

• develops into a seed after fertilisation takes place

What are the conditions for a seed to grow into a seedling?

• warmth

• water

• air

What is the cycle of reproduction in plants?

pollination   →   fertilisation   →   seed dispersal   →   germination

What is Pollination?

Pollination is the process whereby

• pollen is transferred from the anther of a flower to the stigma of a flower of the same type.

What is Fertilisation?

Fertilisation is the process whereby

• the male reproductive cells (pollen) fertilise the egg cell in the ovule, resulting in the development of a seed

Why do seeds need to be dispersed?

• reduce competition for water, air, sunlight, space and mineral salts

• ensures survivability and spread of their kind

What are the methods for seed/fruit dispersal?

• wind

• water

• animal

• splitting/ explosive action

• fruits sometimes help in dispersal of seeds

What is Germination?

A seed develops into a new plant
