BIO3

Question 1

Cell culture

Answer 1

•a technique in which cells are grown in a laboratory environment in test tubes, petri dishes or flasks

Question 2

Cell lines

Answer 2

• The generations of cells that result from growth and division in each cell culture

Question 3

Stem cells

Answer 3

• “Blank Slate” cells that divide to produce all other types of specialized cells.

Question 4

Prokaryotic Cells

Answer 4

•No true nucleus
• No membrane-bound structures
• All are unicellular
• Unicellular = one-celled
• Examples: Bacteria

Question 5

Eukaryotic Cell

Answer 5

• Has a true nucleus
• Has membrane-bound organelles
• Some unicellular, most
MULTICELLULAR
• Examples: Animals, Plants, and Fungi

Question 6

Cell Membrane

Answer 6

SECURITY GUARD
-bouncer at a VIP party, decides what comes in and out and communicates to the bosses

Question 7

Selective Permeability

Answer 7

• A process in which cell membrane allows some molecules to pass in while keeping others out.
•Ex: Window Screen
• Water: in and out freely
• Sodium, Potassium, & Calcium ions: only at certain times, at certain amounts, through certain channels

Question 8

Phospholipid Bilayer

Answer 8

• Plasma membrane composed of two layers of phospholipids back-to-back
Fluid Mosaic Model: model

Question 9

Fluid Mosaic Model

Answer 9

model of plasma membrane
• “Fluid” =Phospholipids move within membrane like water molecules in lake
• Proteins embedded in membrane move along phospholipids like boats
• Proteins create mosaic pattern on membrane surface

Question 10

Cholesterol

Answer 10

• Stabilizes phospholipids by preventing fatty acid tails from sticking together

Question 11

Rough endoplasmic reticulum

Answer 11

FACTORY ASSEMBLY LINE
-studded with ribosomes. Proteins are made here.
produced and transports molecules also storage

Question 12

Smooth endoplasmic reticulum

Answer 12

FACTORY ASSEMBLY LINE
-lipid synthesis and detoxification and storage and transportation

Question 13

Ribosomes

Answer 13

BODY BUILDERS/CONSTRUCTION WORKERS
- building proteins
-float freely in cell or attached to rough ER
-just as construction workers follow blueprints the use cells DNA ;for ; instructions

Question 14

golgi apparatus

Answer 14

SHIPPING DEPARTMENT
- recieves, modifies, sorts, ships out protein and lipids to proper destination in or out the sell

Question 15

Mitochondria

Answer 15

FACTORY
- responsible for producing energy
- tiny but strong factories
- cellular respiration
- take in energy and nutrients and oxygen to covert to energy rich molecules ATP

Question 16

Vacuole

Answer 16

STORAGE XONRAINERS
- store substances like water waste and nutrients
-maintains internal pressure
- in plant cells they are big and provide structural support

Question 17

Lysosomes

Answer 17

RECYCLING BIN
-contains enzymes that beak down waste materials like old cell parts and foreign invaders
- cells garbage disposal cleaning up and breaking down

Question 18

cytoskeleton

Answer 18

SKELETON
-provide structural support so the shape
- made of protein filaments like micro tubes micro filament and other thing

Question 19

centriole (not organelle)

Answer 19

CELL DIVIDERS / REFS
organizers of cell division
help ensure chromosomes are properly distributed during cell division
composed of micro tubes
organize spindle fibres

Question 20

Cicila and Flagella

Answer 20

CELL PROPELLERS
-hair like structures that protrude from surface of some cells
-enable movement
-move substances along cell surface
FLAGELLA-longer and fewer in number
CICILA- shorter and numerous
