Carpel |
Female part of the flower, also known as the pistil. This contains the stigma, style and ovary at the bottom. |
|
|
What is the male part of the flower |
Stamen, this includes the anther and filament. |
|
|
Sepal |
Are like leaves that protects the flowering bud |
|
|
What produces the pollen |
Anther |
|
|
Filament |
Holds the anther up |
|
|
What is the male sex cell produced by anthers |
Pollen |
|
|
Ovule |
Contains the egg cell and develops into seed |
|
|
What is the structure which contains the ovules |
Ovary |
|
|
Egg |
Female sex cell |
|
|
What holds the stigma up |
Style |
|
|
Stigma |
Collects the pollen |
|
|
Pollination |
Transfer of pollen from anther to stigma |
|
|
What is gamete and sex cell |
Another name for pollen and egg |
|
|
What is the cell formed after egg is fertilized |
Zygote |
|
|
What grows from the zygote |
Seed |
|
|
Fruit |
The ovary grows into this after fertilization |
|
|
Fertilization |
The joining of the pollen nucleus (male cell) with the ovule nucleus (female cell) |
|
|
Tetsa |
Tough protective coat of the seed |
|
|
Radicle |
Root in the plant embryo |
|
|
Plumule |
Leaf inside the embryo |
|
|
Micropyle |
Hole where air and water get into the seed |
|
|
Cotyledon |
Where food is stored inside the seed |
|
|
Germination |
Where seeds have enough moisture and warmth that the grow |
|
|
What is asexual reproduction? |
This is when a plant fertilized itself but it's own pollen entering it's stigma. Only one plant involved. |
|
|
What is sexual reproduction? |
This is when pollen from one plant travels to another plants stigma. 2 parents (plants) involved. |
|
|
How can plants attract insects? |
Attract insects with their bright colours, scent and nectar. |
|
|
Give an example of wind pollination. |
The stigma is is hairy and feathery to be able to catch pollen blown by the wind. |
|
|
Give an example of insect pollination. |
The anther are upright and in the flower so the pollen can brush off on insects to go to another plant. |
|
|
Cross pollination |
This is when pollen transfers from one plants anther to another plants stigma. |
|
|
Why do plants need to disperse? |
So the mother plant is not fighting for food and water with the new plant/seed. Aswell as spreading the new paint far away to avoid overcrowding. |
|
|
What is wind dispersal? |
When seeds are carried through the wind to create other plants. |
|
|
What is animal dispersal? |
When a animal eats or has a seed attaches to it and it carries it away and excretes it or it falls off. |
|
|
What is water dispersal? |
When a plant seed gets carried via and stream or river. |
|
|
Asexual plant example |
Pine tree |
|
|
Some flowers make it so their stigma and anther grow at different times to avoid self pollination. Self pollination can be bad because it lacks generation diversity to help plants survive |
Hdjdh |
|
|
Why r plants dying |
Pollution, pesticides and invasive species. |
|
|
Photosynthesis? |
Photosynthesis combines carbon dioxide, water and using the sunshine energy to create glucose for the plant to use for energy. They produce a waste gass called oxygen. |
|
|
What is the stomata? |
These are little holes in the leaf where carbon dioxide is absorbed and in these pores (stomatal pores) oxygen is released. |
|
|
What are the guard cells? |
These are around the stomata and controls them. |
