-
Diff in animal vs plant cells
- plants have cell wall for support and protection
- plant cells have plastids
- plant cells have large, central sap vacuole that stores water
- animal cells have lysosomes, sacs of hydrolytic enzymes that can digest large organic molecules
- animal cells have centrioles, organelles that function during cell division
-
5 factors that can affect rate of diffusion
- temp
- physical nature of environment
- permeability of membrane
- size and shape of diffusing molecules
- size of gradient between high and low concentrations
-
Plant cell and animal cell at iso=
no change in either
-
Plant cell/animal cell at hypertonic=
plant=plasmolysis, animal=crenation, water leaving both
-
plant cell/animal cell at hypotonic =
tugor for plant, lysis for animal, water coming in on both
-
Advantage/importance of photosynthesis
light converted to chemical energy, inorgainic moles are converted to organic moles and O2 is released as an end product
-
As temp increases breakdown of food
increases, b/c enzymes are doing work and they work faster in hotter temps
-
Advantage of aerobic respiration
makes 36-38 ATP, fermentation makes only 2
-
alcohol fermentation advantage is
requires no O2
