I ♥ SCIENCE: POLLINATION AND FERTILIZATION

POLLINATION AND FERTILIZATION

How do flowering plants reproduce?

Let's find out what pollination and fertilization are.

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

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.

Who is in charge of pollination? Any idea?

Point to the humming bird.
Point to the bee.
Point to the butterflies.
They all help the flowers's pollination.

The Pollination Process

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').

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

SCIENTISTS DOING RESEARCH

It's time to do research (further investigation). Get in groups of four anwer the following questions after watching the videos.

Life Cycle of a Flowering Plant

1.Are female and male parts of the flower separed?
2.How do plants attract insects and birds?
3.Where are ovules made?
4.Where is pollen made?
5.When does fertilization occur?
