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&raquo_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&raquo_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&raquo_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&raquo_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&raquo_space; energy&raquo_space; ATP (£)
  • inner membrane = cristae
  • fluid interior = matrix
