Flashcards in Organelles Deck (19):
1

Cell membrane

(all cells)
-protects the cell
-creates a barrier between inside and outside
-controls what enters and exits the cell

2

Cell wall

(plant cells)
-made up of cellulose
-thick, rigid wall located just outside the cell membrane

3

Cytoplasm

(all cells)
-jelly-like liquid inside cell membrane
-contains organelles
-location of many chemical reactions

4

Nucleus

(plant and animal cells)
-control center of the cell
-contains DNA
-surrounded by membrane called the nuclear envelope (protection)

5

Nuclear Envelope

(plant and animal cells)
-surrounds and protects the nucleus

6

Nucleolus

(plant and animal cells)
-special region inside nucleus
-where ribosomes are made

7

Ribosomes

(all cells)
-are proteins that make proteins
-can be free or attached
-free in cytoplasm
-attached in the Rough ER

8

Rough Endoplasmic Reticulum

(plant and animals cells)
-always near nucleus
-makes proteins and other cell products for export out of the cell
-studded with ribosomes

9

Smooth Endoplasmic Reticulum

(plant and animals cells)
-makes the cell membrane
-detoxify drugs
-has many enzymes
-no ribosomes

10

Golgi Apparatus

(plant and animal cells)
-collects, modifies, packages, and ships cell products
-receives cell products from ER
-sends modified cell products to cell membrane

11

Transport Vesicle

(plant and animal cells)
-small membrane-bound compartments
-transport compounds around the cell

12

Lysosome

(animal cells)
-contains digestive enzymes surrounded by a double membrane
-recycles worn-out cell parts
-digests food
-can digest other cells

13

Vacuole

(plant and animal cells)
-larger in plants
-stores water, food, nutrients, and cell products

14

Chloroplast

(plant cells)
-converts sunlight to food

15

Mitochondria

(plant and animal cells)
-converts food into energy

16

Cytoskeleton

(plant and animal cells)
-skeleton of cells
-provides structure, shape, and movement

17

Centriole

(animal cells)
-involved in cellular reproduction

18

Cilia

(can be in plant, animal, and prokaryotic cells)
-not all cells have cilia
-small, hair-like projections
-provide movement

19

Flagella

(can be in plant, animal, and prokaryotic cells)
-not all cells have flagella
-whip-like tail
-provide movement
-usually only one or a few on a cell
