|
Definition
-enclosed in a plasma membrane
-surrounded by a cell wall that is covered by a gel capsule
Contains:
-ribosomes
-mesosomes
-chromatin bodies |
|
|
Term
|
Definition
Flagella:
-used for movement
Pili (hairlike outgrowths):
-used to attach some types of bac to surfaces
-to exchange genetic material with other bacteria |

-Largest Prokaryotes
AKA Blue-green algae
Contain chlorophyll a and accessory pigments for photosynthesis.
-Pigments not in chloroplasts |
|
|
Term
|
Definition
| -photosynthetic membranes in cyanobacteria |
|
|
Term
|
Definition
| Often surround cyanobacteria |
|
|
Term
|
Definition
-membrane bound nuclei and organelles
-cytoplasm forms matrix
-structurally more complex the prokaryotes |
|
|
Term
|
Definition
-elliptical green organelles in plant cells
-site of photosynthesis in plant cells
-green because they contain chlorophyll |
|
|
Term
|
Definition
-organelles in plant and animal cells
-where aerobic respiration occurs
-Surrounded by 2 membranes
inner folds in to form cristae which hold respiratory enzymes and other large respiratory molecules in place.
-Some DNA also occurs here |
|
|
Term
|
Definition
| All of the material and organelles contained by the plasma membrane |
|
|
Term
|
Definition
-bounded by a vacuolar membrane
-Occupies 90% of the volume of a mature cell.
Functions:
-storage of organic and inorganic molecules, ions, water, enzymes, and waste products |
|
|
Term
| Cytoplasmic Streaming/Cyclosis |
|
Definition
| movement of chloroplasts due to intense light/heat |
|
|
Term
|
Definition
Composed of:
-outer primary cell wall (deposited during growth of the cell)
-middle lamella (the substance holding walls of 2 adjacent cells together)
- |
|
|
Term
|
Definition
the protoplasm of adjacent cells is connected by these cytoplasmic strands.
penetrate cell walls |

|
Term
| How are specimens stained? |
|
Definition
| By adding a dye that preferentially colors some parts of the specimen but not others. |
|
|
Term
|
Definition
| Organelles where food is made and stored |
|
|
Term
|
Definition
| Plastids that store starch and therefore stain darkly with iodine. |
|

Definition
-irregularly shaped protist with many internal organelles
Structures:
-pseudopodia
-contractile vacuole that accumulates and expels water and waste products |
|
|
Term
