Module 1 - Cells as the basis of life

Question 1

Cell

Answer 1

The smallest structural and functional unit in a living thing. A cell has a cell membrane and contain cytoplasm organelles and genetic material (DNA)

Question 2

Cell membrane

Answer 2

A double layer of phospholipids that encloses the contents of a cell.Control the movement in and out of the cell.
(founders on the outside of cell)

Question 3

Cytoplasm

Answer 3

The fluid of a cell. With organelles surrounding it.

found in centre of cell

Question 4

Organelle

Answer 4

Has more than one job in the cytoplasm of a cell with other cell parts in it.
(including nucleus, Golgi, endoplasmic, ect.)

Question 5

Nucleus

Answer 5

An organelle that contain genetic information and directs the activity of a cell.
( found in the centre of the cell)

Question 6

Ribosome

Answer 6

A small organelle made of protein and RNA.

Question 7

Golgi body

Answer 7

An organism made of a stack of cistern which makes protein.

Question 8

Prokaryotic

Answer 8

A organism that do not have a cell membrane surrounding the nucleus and lack organelles.
(All are bacteria)

Question 9

Eukaryotic

Answer 9

An organism whose cell contains a cell membrane bound nucleus.
(fungi, plants)

Question 10

Cell wall

Answer 10

An external structure that surrounds the cell membrane for structure support/protection. Composed of cellulose in plants or peptidoglycan in bacteria.
(found on the outer layer of cell)

Question 11

Mitochondria

Answer 11

Power house of cell provides energy (ATP) for aerobic cellular respiration.

Question 12

Surface area (SA:V)

Answer 12

When a cell is very small and has a large surface are to volume ratio.

Question 13

Vacuole

Answer 13

Storage bubbles in cell, may store food and nutrients needed for survival.

Question 14

Chloroplast

Answer 14

Found in plant cell organelles which conducts photosynthesis.
(energy)

Question 15

Endoplasmic reticulum

Answer 15

Transportation of the eukaryotic cell function is protein folding.

rough. E.R- protein synthesis
smooth. E.R-produces steroids

Question 16

Phospholipid

Answer 16

Liquid molecule that is the main component of the cell membrane.
(includes: fats, waxes and vitamins)

Question 17

Diffusion

Answer 17

How substances move in and out of a cell.

liquids and gasses

Question 18

Osmosis

Answer 18

Movement of a water across a membrane along a concentration gradient form of passive transport.

Question 19

Passive transport

Answer 19

Membrane transport the does not require energy to move substance across the cell membrane.

Question 20

Active transport

Answer 20

The movement of dissolved molecules in or out of a cell through the cell membrane.
