Term
The Cell Theory states:
Definition
1)All living things are made of cells and the products of cells
2) All cells arise from pre-existing cells
Term
All cells have:
Definition
Cell membrane
Cytoplasm
Ribosome
DNA
Term
Cells tend to be small because:
Definition
This maitains a higher surface area to volume ratio, and allows for more efficient diffusion in supplying of the cells needs eg. oxygen supply
Term
Prokaryotic cells lack:
Size:
Definition
Nucleus, membrane bound organelles.
1- 10 um
Term
Prokaryotic cells DNA
Definition
is circular, usually one large chromosome.
Some also have smaller DNA rings calles plasmids.
Term
Prokaryotic cells make up:
Definition
Bacteria and blue-green algae
Term
1) Eukaryotic cells make up:
2) Size:
Definition
1)animals, plants, fungi, protists.
2) 10 - 100 um
Term
What do plant cells contain that animal cells do not?
Definition
Large, central vacuole
Cell wall
Chloroplasts
Carbohydrates stored in starch grains
Term
What do animal cells contain that plant cells do not?
Definition
Centrioles
Carbohydrates stored as glycogen granules
Term
Mitichondria
Definition
For aerobic respiration.
Make ATP to supply energy for cell.
Term
Cell Membrane
Definition
Controls what enters and leaves the cell
Term
Nucleus
Definition
Contains DNA which directs the functions of the cell.
Term
Ribosomes
Definition
The site of protein synthesis
Term
Rough Endoplasmic Reticulum
Definition
Internal transport, has ribosomes attached and modify the proteins produced.
Term
Smooth Endoplasmic Reticulum
Definition
Internal Transport, produces fats and oils.
Term
Golgi Body
Definition
Package cell products for secretion.
Term
Chloroplast
Definition
The site of photosynthesis in plant cells
Term
Cell Wall
Definition
Provides support
Plant cells: made of cellulose
Fungi: made of chitin or chitosan
Bacteria: made of peptidoglycan
Term
Large Vacuole
Definition
Only in Plant cells. Stores water and nutrients.
Term
Lysosome
Definition
Contain digestive enzymes which break down worn out cell components
Term
Cytoskeleton
Definition
Consists of microfilaments, intermediate filaments and microtubules. Supports the cells to maintain shape, enables cell movement, holds organelles in place and strengthens the cell.
