POLLINATION



1. What is the function of a flower?

Flowers help plants make seeds and babies. The different parts of a flower work together to make this happen.

2. How do plants that don't have flowers make babies? 

Some plants, like ferns and mosses, don't have flowers. Instead, they make tiny things called spores that can grow into new plants. Other plants, like pine trees, make seeds without flowers.

3. Why are there so many different flowers?

Flowers come in all different sizes, shapes, and colors because this helps them attract special insects and animals that can help them make seeds. The more variety, the more ways plants can get help to make their babies.

4. Why do flowers have nice smells?

Flowers have nice smells that attract insects and animals that can help them make seeds. The smell is like a sign saying "Come visit me!" to insects and animals.

 



Monosexual Flowers:

Contain either male (stamens) or female (pistils) reproductive organs, but not both in the same flower

Bisexual Flowers:

Contain both male (stamens) and female (pistils) reproductive organs in the same flower

 


Self-Pollination:

1.Occurs when pollen from one part of a plant is transferred to another part of the same plant.

2.This means the plant is pollinating itself.

3.This can happen in flowers that are closed or have a special mechanism to prevent external pollination.

4.Self-pollination helps the plant reproduce, but it can lead to less genetic diversity.


Cross-Pollination:

1.Occurs when pollen from one plant is transferred to another plant of the same species.

2.This means the pollen is coming from a different plant, not the same plant.

3.This often happens with the help of external agents like bees, butterflies, or wind.

4.Cross-pollination helps increase genetic diversity by combining genetic information from different plants.
