Cell Activity Flashcards
What is the function of chloroplasts?
To absorb light for photosynthesis
In which part of the cell is energy released during respiration?
Mitochondria
Where is the DNA found in a bacterial cell?
Cytoplasm (no nucleus)
What type of respiration is fermentation?
Anaerobic Respiration
Why do muscle cells need a lot of mitochondria?
For movement. Energy release occurs in mitochondria
What is the function of a root hair?
To increase the S.A. of the root hair cell
What type of membrane is the cell membrane?
Partially permeable
What term is used to refer to two solutions with identical concentrations?
Isotonic
Why does active transport require energy?
The particles are being absorbed against a concentration gradient
How are leaves adapted to increase their surface area?
They are flat and thin, and have internal air spaces and stomata
How are villi adapted to make them efficient exchange surfaces?
Large S.A.
Thin walls
Good blood supply
If a solution contains more solute and less water, what is it called?
Hypertonic
If a solution contains more water than solutes, what is it called?
Hypotonic
