Bio Test

Front 1

Cell theory.

Back 1

- All living things are composed of cells.
- cells are the basic structure and function of life.
- cells must come from pre-existing cells.

Hint 1

There are three parts to the cell theory.

Front 2

Prokaryotes

Back 2

- No cell membrane or nucleus.
- 0.2 or 2.0 in diameter
- first cell

Hint 2

Manly plant cells.

Front 3

Eukaryotes

Back 3

- a true cell.
- has membrane bound cells.
- 10-100 in diameter.
- mitosis.
Has a nucleus.

Hint 3

Animal cell

Front 4

Cytoplasm

Back 4

- the material inside the cell membrane.
- not including the nucleus.

Hint 4

Is inside the cell.

Front 5

Plasma membrane

Back 5

- made up of a phospholipid bilayer that controls what goes in and out of the cell.

Hint 5

A phospholipid looks like this

Front 6

Cell wall

Back 6

- plant cell: made of cellulose, rigid, for protection.

Hint 6

Only in plant cells

Front 7

Vesicle

Back 7

- store, and transport , or digest cellular products and wast.

Hint 7

Also called the little bladder.

Front 8

Cytoplasm

Back 8

- gel-like substance in which organelles are suspended.
- makes up about 70% of the cell volume.

Hint 8

Cell tissue

Front 9

Lysosomes

Back 9

- membrane bound sac of enzymes site of digestion.
- act as wast disposal for the cell

Hint 9

Dissolving body

Front 10

Ribosomes

Back 10

- reads messenger RNA to make proteins.
- puts the proteins in the R.E.R.

Hint 10

Attached to the R.E.R.

Front 11

Rough endoplasmic reticulum

Back 11

- network of membranes that carry proteins.
- covered in ribosome.

Hint 11

Or the RER

Front 12

Smooth endoplasmic reticulum

Back 12

- a network of membranes involved in making lipids such as steroids, cholesterol, and fats

Hint 12

Or the SER

Front 13

Golgi apparatus

Back 13

- flat, membrane bound sacs that prepare and store proteins for secretion.
- packing center of the cell.

Hint 13

An organelle

Front 14

Mitochondria

Back 14

This is where RESPIRATION takes place.

Hint 14

Not human.

Front 15

Nuclear envelope

Back 15

- phospholipid.
- protein bilayer.
- surrounds the nucleus and controls what goes in and out of it.

Hint 15

Part of the nucleus

Front 16

Nucleus

Back 16

- membrane bound structure that contains the calls hereditary info and controls the cells growth and reproduction.

Hint 16

The center of an animal cell.

Front 17

Nucleolus

Back 17

- the site of ribosome synthesis in the nucleus.

Front 18

Chromatin

Back 18

- long thick stands of DNA in the nucleus.

Front 19

Chloroplast

Back 19

- site of photosynthesis

Front 20

Amyloplast

Back 20

- makes and stores staro.

Front 21

Vacuole

Back 21

- stores water, wast and dissolved material.
- small in animal cell and large In plant cells.

Front 22

Flagella and Cilia

Back 22

- helps the cell move.

Front 23

Passive transport

Back 23

- the movement of molecules from an area of high concentration to an area of low concentration.

Front 24

Active transport

Back 24

- using ATP to move molecules from an area of low concentration to an area of high concentration.

Front 25

Diffusion

Back 25

- the movement of a substance from a area of high concentration to an area of low concentration.

Front 26

Osmosis

Back 26

- is the diffusion of water through a selectively permeable membrane
From an area of high water potential to an area of low water potential.

Front 27

Isotonic

Back 27

Cell solution is the same as the environment.

Front 28

Hypertonic

Back 28

More cells solute in the solution them in the environment.

Front 29

Hypotonic

Back 29

Less solute in the solution then in the environment.

Front 30

Facilitated diffusion

Back 30

- molecules are moved across a membrane from high to low concentration by carrier proteins
