How do prokaryotic cells divide: |
|
Definition
(bateria) Copies its DNA and splits by a process called binary fission |
|
|
Term
How do eukaryotic cells divide? |
|
Definition
(plant/animal cells) have pairs of chromosomes called homologous chromosomes

|
Definition
-
DNA copies itself
-
Nucleus splits evenly - mitosis
-
Rest of cell splits

|
Term
What is needed for photosynthesis and what is produced? |
|
Definition
sunlight + H2O + carbon dixiode = glucose + oxygen |
|
|
Term
What is needed for respiration and what is produced?
|
|
Definition
glucose + oxygen = carbon dioxide + water ATP (energy) |
|
|
Term
What is needed for fermentation and what is produced?
|
|
Definition
gluecose + some O = O2 + lactic acid (or alchohol) |

|
Definition
- diffusion
- osmosis
- passive transport
- active transport
- endocytosis

|
|
|
Term
What is diffusion (molecules)? |
|
Definition
movement of molecules through pores in the cell membrane form an area of high concertration to an area of low consentration |
|
|
Term
What is osmosis (molecules)?
|
|
Definition
Movement of water through pores in the cell membrane from an area of high concentration to an area of low concentration |
|
|
Term
What is passive transport (molecules)?
|
|
Definition
movement of molecules through proteins in the cell membrane from an area of high concentration to an area of low concentration |
|
|
Term
What is active transport (molecules)?
|
|
Definition
movement of molecules through proteins in the cell membrane from an area of low concentration to an area of high concentration **requires energy |
|
|
Term
What is endocytosis (molecules)?
|
|
Definition
movement of large molecules into a cell by forming a vesicle |
|
|
Term
What is exocytosis (molecules)?
|
|
Definition
movement of large molecules out of a cell by forming a vesicle |
|
|
Term
Why would fermentation occur instead of respiration? |
|
Definition
fermenation occurs when not enough oxygen is available for respiration |
