Biology Flashcards
1
Q
Cell membrane
A
- composed of phospholipid bilayer
- controls what enters and edits the cell
2
Q
Nucleus
A
- Contains 46 strands of DNA called chromosomes
- controls all cell functions
3
Q
Ribosomes
A
-where proteins are made
4
Q
Endoplasmic reticulum
A
-Extension off the nucleus
RER= ribosomes are attached
SER= protects proteins as ships it outwards to Golgi
5
Q
Golgi
A
-Modifies proteins and directs them either outwards or back into the cell
6
Q
Mitochondria
A
-provide the energy for the cell
7
Q
Chloroplast
A
Converts sunlight into food (photosynthesis)
8
Q
Vacuoles
A
- plants have a large central vacuole for long term water storage
- Animals have more than one small vacuole
9
Q
Cytoplasm
A
-jelly like substance in which the organalles float around in
10
Q
Lysosomes
A
-contain proteins that function to help keep cells clean
11
Q
Centrioles
A
Protein that help in cell division (reproduction)
12
Q
Cell wall
A
- Used to give plants structure and support
- so strong we cannot digest it
