Flashcards in Chapter 3 Summary Deck (18):
1

Cells

Basic unit of life, microscopic, >100 trillion make up human body, usually specialized to the function, determined by patters of gene expression in a process called cellular differentiation

2

ICM

inner cell mass

3

plasma membrance

primary structure of a cell membrane. provides battier (homeostasis,) controls transport

4

phospholipid layer

double layer of phospholipid molecules (heads out, tails in) hydrophilic, hydrophobic

5

other components

cholesterol, proteins, channel-transport, enzymatic-metabolism, receptor-communication, marker-identification, anchor-tissue integrity

6

Cytoplasm

gel like internal substance inside of cell

7

Nucleus

Nuclear envelope-double phospholipid bilayer,
nuclear pores-openings in the nuclear envelope,
chromatin- genetic material

8

Endoplasmic Reticulum

A winding phospholipid bilayer of canals, tubes, sacs, and flat membranes

9

endoplasmic reticulum rough

-Can see ribosomes, looks textures
function in protein synthesis

10

endoplasmic reticulum smooth

no ribosomes, synthesizes certain lipids & ?

11

Ribosome

Nonmembraneous structures, made of 2 parts, each sub units is

12

Golgi apparatus

Consists of stacked cisternae (Golgi bodies) cisternae produce vesicles (pinching off) (packaging facility)

13

Lysosomes

Made of microscopic membrane sacs (pinched off from Golgi apparatus,) contain digestive enzymes, digest defective/old/useless cell parts
Neutrophils

14

Mitochondria

Composed of a double membrane system. Outer membrane, inner membrane w/cristae matrix. Cell respiration. Produce ATP. "Power plants" of cells.

15

Microvilli

Microvilli textures cells, extension of the membrane and cytoplasm of the cell. Back and forth, more than one.

16

Cilia

Short cell process made of microtubules
Coordinated movement

17

Flagella

One flegellum, spins/rotating motion

18

Cell extensions

Microvilli, cilia, flagella
