Flashcards in Organelles Deck (30):
1

What are the two kind of organelles

Membrane bound

Non membrane bound

2

Non membrane bound organelles

Centrosome
Cilia & flagella
Ribosomes
Cytoskeleton
Nucleolus

3

Centrosome

Also called centrioles

Used as anchor points during cell division

Part of cytoskeleton

4

Cilia and flagella

Protein structures extending outward from the plasma membrane that either moved things passed the cell or causes the cell to move

5

Cilia

Respiratory tract

6

Flagella

Sperm

7

Ribosomes

Most numerous of the organelles in a cell

Site of protein synthesis

8

Types of ribosome

Fixed/attached/rough ER

Free/unattached/smooth ER

9

Organelles

Specialized structure w cell

Have specific shape and functions

10

Nucleolus

Site of ribosome formation

11

Cytoskeleton

3 categories of proteins w different functions

12

What are the 3 categories of protein in the cytoskeleton

Microfilaments

Microtubules

Intermediate filaments

13

Microtubules

Used for cell division

14

Intermediate filaments

Cytoplasm streaming

Move cytoplasm

Give cell shape

15

Microfilaments

Have ability to contract

Muscle cells (actrin/myosin)

16

Membrane bound organelles

endoplasmic reticulum
Golgi apparatus/body
Lysosomes
Proteasomes
Peroxisomes
Transport vesicles
Mitochondria
Golgi complex

17

Endoplasmic reticulum

ER

Series of tubes and channels for transport of proteins and other substances

18

What does ER stand for

Endoplasmic reticulum

19

What are the different types of endoplasmic reticulum?

Smooth ER

Rough ER

20

Golgi apparatus/body

Golgi complex

Warehouse for modification and packaging and secretions of proteins and protein compounds

21

Proteasomes

Catabolism of proteins

22

Peroxisomes

When toxins get inside cells, it breaks it down

toxins such as fatty acids, drugs, alcohol, hydrogen-peroxide(converts it to water and oxygen)

23

Transport vesicles

Secretory and storage

24

What is a big vesicle called

Vacuole

25

Vacuole

Large vesicle used for storage

Ex plants vacuole stores water

26

Mitochondria

Powerhouse

Making of atp

27

What do ribosomes that are free do?

Make proteins for inside the cell

28

What is catabolism

Only half metabolism

29

Metabolism is

Catabolism and anabolism

30

What structures are double membrane bound?

Plasma membrane

Mitochondria

Nucleus

Plastid (only in plants)
