The Cell

Question 1

2 types of cells in the body

Answer 1

1 SEX CELLS (sperm and oocytes)

2 SOMATIC CELLS

Question 2

CYTOLOGY

Answer 2

study of cells

Question 3

Cell Components

Answer 3

PLASMALEMMA (cell membrane)
CYTOPLASM
CYTOSOL
ORGANELLES
NONMEMBRANEOUS ORGANELLES
MEMBRANEOUS ORGANELLES

Question 4

Plasmalemma Components

Answer 4

phospholipid bilayer (hydrophilic heads, hydrophobic tails)
glycolipids (outer layer, functions as receptor)
protein (peripheral proteins are attached to membrane, integral proteins are embedded)
cholesterol (stabilize structure, maintains fluidity)

Question 5

Plasmalemma Functions

Answer 5

physical isolation
selective permeability
structural support
sensitivity

Question 6

3 Passive Processes

no cellular energy

Answer 6

1 DIFFUSION (mvmt of molecules fr high concentration to low)
2 OSMOSIS (diffusion of water)
3 FACILITATED DIFFUSION (diffusion w carrier proteins)

Question 7

3 Active Processes

uses ATP + carrier proteins

Answer 7

1 ACTIVE TRANSPORT
2 ENDOCYTOSIS
3 EXOCYTOSIS (removal of fluid/substance fr cell by vesicle exiting)

Question 8

ACTIVE TRANSPORT

Answer 8

carrier proteins can move against opposing concentration gradient (fr low concentration to a higher)

Question 9

ENDOCYTOSIS

Answer 9

1 PINOCYTOSIS entrance via vesicle
2 PHAGOCYTOSIS surrounds particle to eat
3 RECEPTOR-MEDIATED molecule binds to receptors on membrane surface targeting formation of ventricle

Question 10

2 subdivisions of Organelles

Answer 10

NonMembranous Organelles

Membranous Organelles

Question 11

6 Nonmembranous Organelles

Answer 11

1 Cytoskeleton
2 Microvilli
3 Centrioles
4 Cilia
5 Flagella
6 Ribosomes

Question 12

6 Membranous Organelles

Answer 12

1 Mitochondria
2 Nucleus
3 Endoplasmic Reticulum
4 Golgi Apparatus
5 Lysosomes
6 Peroxisomes
