Flashcards in Eukaryopolis - The City of Animal Cells Deck (13):
1

Cell Surface Membrane (border police)

- encloses cell contents
- Controls what goes in and out of cell
- Selective permeability

2

Cytoplasm

- Water + Nutrients
- Cytoskeleton

3

Cytoskeleton (infrastructure)

- Microfilaments (actin = movement = cell devision)
- Microtubules ("Scaffolding" = shape. Tracks = move stuff)
- Intermediate Fibres (Strength + Integrity)
- Centrioles (2 = 1 centrosome = spindle fibres = cell devision)

4

Endoplasmic Reticulum (Highway system)

- Carry stuff around the cell
-Smooth = makes lipids
and carbs
- Rough = protein synthesis

5

Ribosomes

- Makes proteins (Amino acids >> polypeptide)
- float freely/attached to nuclear envelope)

6

Golgi Apparatus (post office)

- Processes and packages proteins
- sends products out
- made of stacks of membranous layers (Golgi bodies)

7

Golgi Bodies

- Proteins >> Hormones
- Proteins + Carbs = Molecules
- Packages proteins into vesicles

8

Vesicles

- Phospholipid membranes
- ships out golgi products

9

Lysosomes (recycling centre)

- Sacks full of enzymes
- Digests cell waste
- Cell waste >> building material

10

Nucleus (beloved leader)

- Stores DNA
- uses DNA to make "laws"
- Holds DNA in chromatin

11

Chromatin

- Holds DNA
- cell devision >> chromosomes

12

Nucleolus

- made of RNA
- Makes rRNA
- makes ribosomes

13

Mitochondria (Warp core of the cell)

- Controls respiration
- Carbs/fats >> energy >> ATP (£)
- inner membrane = cristae
- fluid interior = matrix
