1
Q
Cell Surface Membrane (border police)
A
- encloses cell contents
- Controls what goes in and out of cell
- Selective permeability
2
Q
Cytoplasm
A
- Water + Nutrients
- Cytoskeleton
3
Q
Cytoskeleton (infrastructure)
A
- Microfilaments (actin = movement = cell devision)
- Microtubules (“Scaffolding” = shape. Tracks = move stuff)
- Intermediate Fibres (Strength + Integrity)
- Centrioles (2 = 1 centrosome = spindle fibres = cell devision)
4
Q
Endoplasmic Reticulum (Highway system)
A
- Carry stuff around the cell
- Smooth = makes lipids
and carbs - Rough = protein synthesis
5
Q
Ribosomes
A
- Makes proteins (Amino acids»_space; polypeptide)
- float freely/attached to nuclear envelope)
6
Q
Golgi Apparatus (post office)
A
- Processes and packages proteins
- sends products out
- made of stacks of membranous layers (Golgi bodies)
7
Q
Golgi Bodies
A
- Proteins»_space; Hormones
- Proteins + Carbs = Molecules
- Packages proteins into vesicles
8
Q
Vesicles
A
- Phospholipid membranes
- ships out golgi products
9
Q
Lysosomes (recycling centre)
A
- Sacks full of enzymes
- Digests cell waste
- Cell waste»_space; building material
10
Q
Nucleus (beloved leader)
A
- Stores DNA
- uses DNA to make “laws”
- Holds DNA in chromatin
11
Q
Chromatin
A
- Holds DNA
- cell devision»_space; chromosomes
12
Q
Nucleolus
A
- made of RNA
- Makes rRNA
- makes ribosomes
13
Q
Mitochondria (Warp core of the cell)
A
- Controls respiration
- Carbs/fats»_space; energy»_space; ATP (£)
- inner membrane = cristae
- fluid interior = matrix
