Mindmap
Plants are AUTOTROPHS:They make their own food, through PHOTOSYNTHESIS.
Nutrition
During the day, plants take in carbon dioxide and release the oxygen they don't need.

Plant Respiration
Self-pollination vs. Cross-pollination
female parts
male parts
Sexual Reproduction:Pollination
1 : The pollen (on the anther) needs to stick to the stigma.2 : From there it travels down the style.3: When it's in the ovary, it fertilizes the ovules.4 : The ovules become seeds.5 : When the flower dies, the seed is spread.

How Does Pollination Happen?
How Do Coconuts travel?
How are seeds spread?Seed Dispersal
TUBERS: Thick stems that grow underground.
Potatoes
Ginger
Strawberries
RHYZOMES: similar to stolons, but these grow underground.
Stems which grow horizontally along the ground, called STOLONS
non-flowering plants reproduce with spores.
+info
some Flowering plants reproduce without seeds:
Asexual Reproduction
Plants provide food for other animals and sometimes, they also provide a home.
Climate change is caused by the the release of carbon dioxide. Who loves carbon dioxide? PLANTS! By planting more forest and plants, we can help reduce global warming!
They produce the oxygen that all living things need to stay alive!
We get nutrients and energy from the glucose produced by some plants.
Benefits Derived From Plants
In conclusion, plants are important for life on Earth:Save the plants!
