KEY TERMS

Question 1

Cell

Answer 1

The smallest structural + biological unit of all known organisms

Question 2

Eukaryotic Cell

Answer 2

(Unicellular or Multicellular) cells of animals, plants + fungi

Membrane bound organelles

Question 3

Prokaryotic Cells

Answer 3

(Unicellular) Bacterial cells, that don’t contain membrane bound organelles

Question 4

Organelle

Answer 4

Tiny Organ

Question 5

Cell Membrane

Answer 5

Controls the movement of substances in and out of the cell

selective permeability

Question 6

Nucleus

Answer 6

Contains the genetic material to make/produce proteins

Question 7

Cell Wall

Answer 7

Made of cellulose fibres, strengthens the cell

Question 8

Chloroplast

Answer 8

Contains chlorophyll (green pigment) which absorbs light for photosynthesis

Contains Enzymes

Question 9

Permanent Vacuole

Answer 9

Filled with sap, this pushes organelles + cell contents to the cell wall

This keeps the cell turgid

Question 10

Mitocondrion

Answer 10

Located in the cytoplasm, responsible for aerobic respiration

Folded membrane inside

Question 11

Ribosome

Answer 11

The site of protein synthesis

Question 12

Lipid

Answer 12

Fats + Oils

Question 13

Clinical Case Study

Answer 13

An academic publication of medical cases that haven’t been described before or are unusual

Question 14

Disease

Answer 14

A diagnosed condition that prevents ‘normal’ function of an organism

Question 15

Communicable Disease

Answer 15

A infectious disease

Question 16

Non-communicable Disease

Answer 16

A non-infectious disease

Question 17

vesicle

Answer 17

specialised vesicles contain powerful digestive enzymes and proteins

Question 18

golgi apperatus

Answer 18

stack of membrane bound flattened sacks.

Complex protein molecules are stored in vesicles and sent from the ER to the golgi, then distributed around the cell

Question 19

chloroplast

Answer 19

site of photosynthesis,

uses water, light and C02 to build sugar

Question 20

smooth ER

Answer 20

a series of flattened membrane bound sacks

no ribosomes

makes lipids

Question 21

rough ER

Answer 21

a series of flattened membrane bound sacks

transports proteins made in ribosomes to where they need to go

Question 22

nuclear membrane

Answer 22

contains pores to let relatively large molecules pass through

Question 23

nucleolus

Answer 23

makes RNA which is made into Ribosomes

Question 24

protoplasm

Answer 24

cell contents inside the fluid cytoplasm

Question 25

ER

Answer 25

endoplasmic reticulum series of membrane-bound flattened sacks, called cisternae

Question 26

lysosomes

Answer 26

specialised vesicles surrounded by a single membrane. Contain powerful digestive enzymes that break down materials
