Flashcards in Chapter 4 - Cells, Tissues, and Organs Deck (46):
1

plasma membrane

outer layer of cell.
Regulates what enters and leaves the cell. Participates in growth, reproduction, and interaction.

2

microvilli

short extensions of the cell membrane
absorbs material into the cell

3

nucleus

large, dark celled organelle near the center of the cell, composed of DNA and proteins
contains chromosomes

4

nucleolus

small body in the nucleus; composed of RNA, DNA, and protein
makes ribosomes

5

cytoplasm

colloidal suspension that fills the cell

6

cytosol

the fluid portion of the cytoplasm

7

endoplasmic reticulum (ER)

network of membranes within the cytoplasm. Rough ER has ribosomes attached, smooth does not.
Rough ER sorts proteins and forms them into complex compounds.
Smooth ER involved with lipid synthesis.

8

ribosomes

small bodies free in the cytoplasm, or attached to ER, composed of RNA and protein
manufactures proteins

9

mitochondria

large organelles with folded membranes inside. Converts energy from nutrients in ATP.

10

Golgi apparatus

Layers of membranes
Makes compounds containing proteins.
Preps for transport

11

lysosomes

Small sacs of digestive enzymes

12

Peroxisomes

Membrane enclosed organelles containing enzymes.
Breakdown harmful substances

13

vesicles

Small membrane bound sacs in the cytoplasm
Store and move materials

14

centrioles

Rod shaped bodies (usually 2) near the nucleus
Separate chromosomes during cell division.

15

cilia

Short hail-like, move fluids around the cell.

16

flagellum

Long whip-like, moves the cell.
