Cell Bio Test

Question 1

Dependent variable

Answer 1

What data did you collect( the condition that results from the change in the dependent variable)

On the y axis

Question 2

Control group

Answer 2

The part of the experiment that does not change

Question 3

Experimental group

Answer 3

The test group

All the conditions are the same as in the control group except for one variable which is being tested

Question 4

How many variables can you have in an experiment

Answer 4

Only 1

Question 5

What are the levels of organization

Answer 5

Atom-molecule-cell-tissue-organ-organ system-organism-population-community-ecosystem-biosphere

Question 6

How do we consider something living

Answer 6

• It’s made of cells
• Obtain/use energy
• Grow and develop
• Reproduce
• Respond to environment

Question 7

What should all living things be able to do

Answer 7

Synthesize

Breakdown

Metabolism

Maintain homeostasis

Question 8

Homeostasis

Answer 8

Equilibrium of an organisms internal environment that maintains conditions suitable for life

Ex sweating, shivering

Question 9

What are the four types of biomolecules

Answer 9

Protein

Nucleic acid

Carbs

Lipids

Question 10

What is cell specialization

Answer 10

When a group of cells work together by performing individual tasks for large organs and tissues

Ex. Blood cells carry nutrients/skin cells protect the interior of the body

Question 11

What scientist contributed to the cell theory

Answer 11

Matthias schleden

Theodore Schwann

Question 12

What are the three main things of the cell theory

Answer 12

All living things are composed of cells,
cells are the basic units of life,
cells come from existing cells

Question 13

What is TEM

Answer 13

Transmission electron microscopy

A technique in which a beam of electrons is transmitted through an ultrathin specimen

Question 14

Prokaryote

Answer 14

No nucleus

Question 15

Eukaryote

Answer 15

Has a nucleus

Question 16

What do you plant cells have that animal cells don’t

Answer 16

Chloroplast, cell wall, vacuole

Question 17

Diffusion

Answer 17

Movement of particles from an area of higher concentration to an area of lower concentration

Question 18

Osmosis

Answer 18

Diffusion of water molecules through a selectively permeable membrane

Question 19

Hypertonic solution

Answer 19

More solute in the water then in the cell

Question 20

Hypotonic solution

Answer 20

More solutes in the cell then in the water

Question 21

Isotonic solution

Answer 21

Same amount of solutes in and out of the cell

Question 22

Active transport

Answer 22

Requires ATP=energy/
particles move low to high/
against the flow/
ex. membrane pumps/
endocytosis in by the vesicle/
Exocytosis out by the Vesicle (golgi apparatus)

Question 23

Passive transport

Answer 23

Requires no energy
Particles move high to low
Towards equilibrium

Facilitated diffusion - towards equilibrium [must use protein channels(carrier proteins)] large molecules(glucose)
Diffusion - small molecules move through the lipid membrane/ perfume/ burning candle

Osmosis-water only/hypotonic cell gets water/hypertonic cell looses water/isotonic equal

Question 24

Protein

Answer 24

Monimer= saceride

builds muscle
is in cell membrane
allows large molecules through
allows ions through makes enzymes

Question 25

Carbohydrates

Answer 25

Monimer= monosaccharides(simple sugars ex. Glucose) and disaccharides (2 simple sugars bound together ex glucose+fructose=sucrose) Sugar Contains a lot of carbon

Question 26

Lipids

Answer 26

Monimer= glycerol, fatty acid chains Fats waxes and oils saturated is solid at room temp non-saturated is liquid at room temp

Question 27

Nucleic acid

Answer 27

Monimer= nucleotide ``` in your nucleus Deoxyribonucleic acid(DNA) ```

Question 28

Independent variable

Answer 28

The thing in the experiment that is changed Goes on the x axis

Question 29

Facilitated diffusion

Answer 29

Towards equilibrium/must use protein channels (carrier proteins/large molecules(glucose)
