What does Photosynthesis Do? |
|
Definition
Converts Sunlight into energy for plants
Carbon Dioxide and Water are convereted into glucose. Light is required during this process |
|
|
Term
| Is Photosyntheis a form of cellular respiration? |
|
Definition
Yes
Chlropoasts use thylakoids (membranes that use light reactions)
Chlorophyll is a pigment that absorbs light |
|

Term
| What are two transport mechanisms for cell respiration |
|
Definition
| Exocytosis and Endocytosis |
|
|
Term
|
Definition
A substance is too large to cross a cell membrane, how it ingests food.
Categories:
Phagocytosis: ingestion of particle
Pinocytosis: ingestion of liquid
Receptor Mediated |
|
|
Term
|
Definition
Opposite of endocytosis, exulpsion of dischrage of a substance from a cell
Lysosomes digest particles with enzysems and then expelled |
|
|
Term
| Passive Transport Mechanisms |
|
Definition
Are movements of substances through membranes that do not require energy from the cell, Osmosis & Diffusion
|
|
|
Term
|
Definition
When particles are trasnported from areas of higher concentration to areas of lower concentration. When equilibrium is reached it stops.
Examples: Gas Exchange (CO2 and O) during photosythesis and trasnport of oxygen from air to blood and blood to tissue
Glucose and Amino Acdids are carried by proteins |
|
|
Term
|
Definition
Diffusion of water through semi-permeable membranes
Absortion of water by plant roots, can gain and lose water like this |
|
|
Term
|
Definition
| During cell division, DNA is replicated, and chromatids are two identical pieces of chromosomes that are joined at the centromere to form an X |
