What is passive transport also known as?
Diffusion
What is diffusion also known as?
Passive transport
What is diffusion/passive transport?
Sees the movement of nutrients form areas of high concentration to areas of low concentration
If the diffusion involves water it’s called what?
Osmosis
Does diffusion/passive transport require energy?
No. It doesn’t require energy.
Active transport is what?
It sees the movement of molecules from areas of low concentration to areas of high concentration.
Does active transport require energy?
Yes. Active transport requires energy.
Diffusion/passive transport can be compared to what?
A slide
Active transport can be compared to what?
A ladder
Define ingestion.
How animals obtain their nutrients though the food they eat.
How many ways can food be broken down in an animal.
- Mechanical and Chemical digestion.
What is mechanical digestion?
Chewing. Increases surface area of the food (changes it physically).
What is chemical digestion?
Use enzymes, which act as catalysts for a series of chemical reactions called hydrolysis.
To be in hydrolysis is to be what?
Hydrolyzes. (In verb sorta ig)
Hydrolysis does what?
This process takes large organic molecules and hydrolyzes (“water breaks”) them into smaller organic molecules which can be absorbed into the bloodstream of an animal.
Enzymes are what?
Catalysts that control chemical reactions in organisms.
