Lesson 2--How Plants Make Food

True.

True or false: most fish, all reptiles, and all insects are ectotherms.

False. Very active endotherms have a faster metabolism

True or false: very active endotherms have a slow metabolism

Potassium

What do plants use to open and close stomata?

stomata

the small openings on the undersides of most leaves through which oxygen and carbon dioxide can move

Obtain

to get

maintain

to keep it stable and consistent

Glucose

used by plants as food or stored in long, chain-like molecules called starch

No. Frozen water cannot travel into the roots of the plants.

Can plants live where water is always frozen?

Warm blooded

Endotherms are often called ________ animals.

Water plus carbon dioxide plus sunlight equals plant growth

How do plants grow?

Photosynthesis

The process in which plants use water and carbon dioxide make a sugar called glucose. In this process, plants give off oxygen into the air.

True

True or false: All mammals and birds are endotherms.

True

True or false: Ectotherms often get energy by lying in the sun.

Nitrogen and Phosphorus

What do plants need to build proteins?

In their roots, stems, or leaves

Where do plants in hot areas, such as deserts, store their water?

Chlorophyll

a substance in plants that absorbs sunlight energy and gives plants their green color

Ectotherm

an animal that depends on its environment to warm its body.

endotherm

an animal that uses energy stored in its body to keep its body within a normal temperature range

Transpiration

loss of water from a plant through its leaves

Metabolism

the collection of chemical processes that break down and build molecules in a living organism.
