1. Reproduction and Seeds
Part 6

2. Reproduction Some plants reproduce asexually – budding
Some plants reproduce sexually – egg and sperm
Do plants have sex? NO!!!
They use egg and sperm though

3. Process Pollen is transferred (by wind, animals, etc.) to the flower
The pollen sticks to the stigma of the pistil and moves down the style until it reaches the ovary
In the ovary the pollen (plant sperm) fertilizes an egg
The egg becomes the “baby plant”
The ovary becomes the fruit that surrounds the “baby plant” and gives it food

4. Process

5. Process continued
If this seed is in a fruit, it can be eaten and the seeds dispersed
If this seed is not in a fruit, it has to be dispersed other ways

6. Seed Dispersal Seeds must be dispersed somehow Types of dispersal Wind
Water
Animal fur
Animal eating

7. Wind Dispersal
These plants don’t have large petals to block the wind – they want the wind
The seeds are very light and can be carried easily
Ex: dandelion, maple tree seeds

8. Water Dispersal Some plant seeds are able to float
They can travel on currents and be carried far away
Once they land they can open up and release their seeds
Ex: coconut

9. Animal Fur Some seeds have hooks and barbs
When an animal passes by they hook into the fur and are carried away
Ex: burdocks

10. Animal eating Some seeds are surrounded by fruits
The animals eat the fruit
Digest the fruit
Release the fruit (haha)
The seeds are dispersed
Ex: apples
