|
Define Flower
|
the flower makes seeds for the plant and its pretty colors attracts bees and butterflies
|
|
|
Define Stem
|
the stem supports the plant like the human spine, it contains thin tubes for carrying food
|
|
|
Define Leaves
|
leaves make food for the plant, they take in carbon dioxide and release oxygen into the air
|
|
|
Define Roots
|
roots soak up water and minerals they also store food for the plant.
|
|
|
What do the leaves take in during photosynthesis?
|
they take in sunlight carbon dioxide and water
|
|
|
What do plants release during photo synthesis?
|
They release oxygen
|
|
|
Where do water and nutrients go after they are taken in by the roots?
|
To the stem and leaves
|
|
|
What are the steps of photosynthesis in order?
|
A. The plant takes in sunlight water and carbon dioxide
B. The plant makes food C. The plant gives off oxygen |
|
|
Define Calorie
|
It is a unit to measure energy produced by food in the body
|
|

|
|
Do you need fats in your diet?
|
Yes
|
|
|
Too many fats can cause what?
|
Health problems
|
|
|
Why is the exchange of carbon dioxide and oxygen important for humans?
|
People need oxygen to help them burn digested food and get energy. Unlike plants people cannot make their own food.
|
|
|
Why is the exchange of carbon dioxide and oxygen important for plants?
|
Plants take in carbon dioxide through the stomata and use it for energy. The carbon dioxide is also needed for photosynthesis which is how the plant makes food.
|
|
|
What do plants need in order to grow?
|
Light Air Water Nutrients Space
