Organelles Flashcards
1
Q
Cell membrane
A
(all cells)
- protects the cell
- creates a barrier between inside and outside
- controls what enters and exits the cell
2
Q
Cell wall
A
(plant cells)
- made up of cellulose
- thick, rigid wall located just outside the cell membrane
3
Q
Cytoplasm
A
(all cells)
- jelly-like liquid inside cell membrane
- contains organelles
- location of many chemical reactions
4
Q
Nucleus
A
(plant and animal cells)
- control center of the cell
- contains DNA
- surrounded by membrane called the nuclear envelope (protection)
5
Q
Nuclear Envelope
A
(plant and animal cells)
-surrounds and protects the nucleus
6
Q
Nucleolus
A
(plant and animal cells)
- special region inside nucleus
- where ribosomes are made
7
Q
Ribosomes
A
(all cells)
- are proteins that make proteins
- can be free or attached
- free in cytoplasm
- attached in the Rough ER
8
Q
Rough Endoplasmic Reticulum
A
(plant and animals cells)
- always near nucleus
- makes proteins and other cell products for export out of the cell
- studded with ribosomes
9
Q
Smooth Endoplasmic Reticulum
A
(plant and animals cells)
- makes the cell membrane
- detoxify drugs
- has many enzymes
- no ribosomes
10
Q
Golgi Apparatus
A
(plant and animal cells)
- collects, modifies, packages, and ships cell products
- receives cell products from ER
- sends modified cell products to cell membrane
11
Q
Transport Vesicle
A
(plant and animal cells)
- small membrane-bound compartments
- transport compounds around the cell
12
Q
Lysosome
A
(animal cells)
- contains digestive enzymes surrounded by a double membrane
- recycles worn-out cell parts
- digests food
- can digest other cells
13
Q
Vacuole
A
(plant and animal cells)
- larger in plants
- stores water, food, nutrients, and cell products
14
Q
Chloroplast
A
(plant cells)
-converts sunlight to food
15
Q
Mitochondria
A
(plant and animal cells)
-converts food into energy
