|
|
|
What does the life function, NUTRITION, do?
|
process by which an organism takes in food & uses it for enerty, growth, & repair. INGESTION:
|
|
|
NUTRITION (life function)-
How do plants make their own food? |
Photosynthesis. Plants take in carbon dioxide and water, then produce a sugar called glucose.
|
|
|
What does the life function, TRANSPORT, do?
|
function by which food, water and oxygen are distributed to all cells of the organism. Also carries waste products away. In humans - blood circulatory system does this. In plants - vascular bundles carry materials throughout the organisms.
|
|
|
What does the life function, RESPIRATION, do?
|
provides the organism with energy. Oxygen is brought into the organism & is used to chemically release energy stored in food. Animals - breathing takes in oxygen and releases carbon dioxide. celluar respiration - food & oxygen interact chemically to produce energy & waste (carbon dioxide & water).
|
|
|
What does the life function, EXCRETION, do?
|
the removal of cellular waste products such as water, carbon dioxide, & nitrogen
|
|
|
What does the life function, REPRODUCTION, do?
|
1) organism produces new individuals of the same kind.
2) produces new cells that are necessary for growth and repair. *3) Necessary for survival of species, but not off individual |
|
|
What does the life function, GROWTH, do?
|
increase in the size of the organism.
-reproduction of fnew cells & from the increase in cell size. |
