Flashcards in Bio 141 Notes (2/13/14) Deck (18):
1

Nucleus

compartment that contains the DNA genome

2

Nucleolus

helps make ribosomes

3

Ribosomes are made of...

RNA and protein

4

Endomembrane System

plasma membranes (phospholipid bilayer) surround cell and organelles
cytosol

5

Cytosol

area of cell outside of organelles

6

Endoplasmic Reticulum (ER)

Rough ER and Smooth ER

7

Rough ER

protein synthesis (ribosomes)

8

What makes rough ER rough?

the ribosomes at the surface

9

Ribosomes

protein synthesis
found in rough ER and cytosol

10

Smooth ER

lipid synthesis, protein and modification

11

Golgi Apparatus

packages and ships proteins for use inside or outside of cell

12

Vesicles

small membrane enclosed packets

13

Lysosomes

isolated packets for digestion
(internal recycling or external food)

14

Mitochondrion (Mitochondira)

power plant for cells (all types of Eukayotic cells)
(2 membranes)
involved in cellular respiration (glucose -> energy)
membrane folded upon itself for more membrane area

15

Chloroplast

energy generation (plant cells only)
light energy into food
involved in photosynthesis (sunlight -> glucose)

16

Endosymbiosis

cell eating another cell and living in it

17

Cytoskeleton

structure, transport and support
internal highway for support
protein strands: units include actin and tubulin
transport along microtubules

18

Membranes

boarder patrol
depend upon phospholipids
