Definition
| A cell with no membrane bound nucleus, eg. bacteria. Genetic material is in full contact with cell cytoplasm cell also lacks membrane bound organelles. |
|
|
Term
|
Definition
This is a small circle of DNA seperate from the main circle of DNA in a prokaryotic cell plasmids are transferred between bacteria readily.
|
|
|
Term
|
Definition
| A cell with no membrane bound nucleus and other membrane bound organelles. eg, plant, animal, fungal cells. |
|
|
Term
|
Definition
| This describes the plasma membrane of a cell. The proteins and other bilayer components move between the phospholipids and from above the structure looks like a moving mosaic |
|
|
Term
|
Definition
This is the double layer of phospholipid molecules that forms the plasma membrane of a cell. Phosphoglycerol hydrophilic heads and lipid hydrophobic
tails |
|
|
Term
|
Definition
| This is a protein that is either embedded in one layer of the phospholipid bilayer or spans them both (transmembranal) |
|
|
Term
|
Definition
| This is a protein that is only on the inner or outer surface. |
|
|
Term
|
Definition
These short polysaccharides on the outer surface of the cell are involved in
protection and recognition for the cell. Some can act as antigens. |
|
|
Term
|
Definition
| This is a carbohydrate joined to a protein. Forms part of the glycocalyx |
|
|
Term
|
Definition
| This is a carbohydrate joined to a lipid. Forms part of the glycocalyx |
|
|
Term
|
Definition
Channel proteins create water filled pores/charged channels to transport
charged substances e.g. ions by diffusion |
|
|
Term
|
Definition
A molecule that produces an immune response (can be proteins,
polysaccharides, lipids - usually found on the outer surface of a cell) |
|
|
Term
|
Definition
Organelle where aerobic respiration takes place. Simple outer membrane but
folded inner membrane. |
|
|
Term
|
Definition
| The inner membrane folds of the mitochondria, producing a large surface area. |
|
|
Term
|
Definition
The inner jelly like space of the mitochondria where small circular strands of
DNA are found and also stalked particles where ATP is synthesised by
respiration |
|
|
Term
|
Definition
| Site of photosynthesis bounded by a double membrane |
|
|
Term
|
Definition
| Membrane found in the chloroplast. Inter granal lamellae link grana together |
|
|
Term
|
Definition
| Flattened sacks that contain chlorophyll, where photosynthesis occur. |
|
|
Term
|
Definition
| Formed when thylakoids are stacked together e.g. like coins |
|
|
Term
|
Definition
The fluid matrix inside the chloroplast which contains enzymes, starch grains
and circular DNA |
|
|
Term
| Rough Endoplasmic Reticulum (RER) |
|
Definition
Double membrane channels studded with ribosomes involved in protein
synthesis and modification of the proteins |
