1

Main cell organelles

Ribosome
Mitochondria
Golgi
Rough endoplasmic reticulum
Chloroplast
Lysosomes
Vacuole
Nucleus

2

Function and location of ribosome

Makes proteins
Found in cytoplasm

3

Function of the Mitochondria

The powerhouse of the cell
Produces energy
Found in cytoplasm

4

Function and location of Golgi

Sorting and processing proteins which are then released
Found in cytoplasm next to er

5

Rough endoplasmic reticulum location and function

Assembles proteins
Found in cytoplasm

6

Chloroplast location and function

Conducts photosynthesis
Found in plant cells

7

Function and location of lysosomes

Digest excess of worm our organelles, food particles, and engulfed viruses or bacteria

8

Vacuole function and location

Provides support or rigidity and storage for nutrients and waste matter and can decompose complex molecules
Found in cytoplasm

9

Nucleus location and function

Stores DNA
Cells heredity
Found in centre of nucleus but can depend on cell type

10

Define prokaryote and give an example

Unicellular organisms that lack organelles or other internal membrane-bound structures and therefore do not have a nucleus
An example is bacteria

11

Define eukaryote and provide an example

Organisms made up of cells that posses a membrane bound nucleus (that hold genetic material) as well as membrane bound organelles
Examples are plant and animal cells

12

Plant cells key features

Have:
choloroplasts
Vacuole
Cell wall
Cell membrane
Cytoplasm
Nucleus

13

Animal cells key features

Cell membrane
Nucleus
Cytoplasm

14

Difference between plant and animal cells

The main difference between plant and animal cells is that plant cells have chloroplasts and a cell wall and animal cells don't.

15

Lactase

Breaks down sugar (lactose)

16

Amylase

Breaks down carbohydrates (in mouth-saliva)

17

Profease

Breaks down proteins

18

Lipase

Breaks down fats

19

What do enzymes do

Speed up chemical reactions

20

What are enzymes and what are they made of

Biological catalysts
Made of Proteins

21

Factors that affect activity of enzymes

Temperature
pH
Enzyme concentration
Substrate concentration
Presence of inhibitors or activators
