POLLINATION AND FERTILIZATION

Let's take a look at the parts of a flower to answer the questions.  Can you name them all ?   

the parts of a flower

What is pollination?

It is the process of carrying pollen inside the flower so new seeds can be made. In other words, it is the process of movement of pollen.

Pollination

The pollination process involves the transfer of pollen, from the male part of a plant (in flowers, this is the ‘stamen’) to the female part of the plant (the 'carpel').
Fertilization


Pollen is made in a part called the anther. The eggs are inside the flower in part called the ovaries.

The Plant Pollination Process

The following points correspond to the diagram opposite.

1. Pollen grains land on the sticky stigma.

2. A pollen tube grows down the style, followed by male sperm nuclei.

3. The sperm nuclei fuse with the female ovules.

4. The ovules develop into seed, and the ovary develops into fruit.

Fertilization

It is the process when pollen meets the ovules to make new seeds.

Pollen + ovule = fertilization
