1

State two lab rules;

- Tie long hair back
- Wear safety goggles to protect your eyes when heating substances, dissecting, etc

2

What are the characteristics of life?

- Movement
- Respiration
- Sensitivity
- Growth
- Reproduction
- Excretion
- Nutrition
- Control

3

What does a plant cell contain?

- Nucleus
- Cytoplasm
- Cell membrane
- Cell wall
- Vacuole
- Chloroplast
- Ribosomes
- Mitochondria

4

What does an animal cell contain?

- Nucleus
- Cytoplasm
- Cell membrane
- Mitochondria
- Ribosomes

5

Function of Cell Membrane?
(found in animal and plant cells)

Controls what substances can get in and out of the cell

6

Function of a Cytoplasm?
(found in plant and animal cells)

Jelly-like substance, where chemical reactions happen. In plant cells there’s a thin lining, whereas in animal cells most of the cell is cytoplasm.

7

Function of a Nucleus?
(found in plant and animal cells)

Contains genetic material, which controls the activities of the cell

8

Function of Mitochondria?
(found in plant and animal cells)

Most energy is released by respiration here

9

Function of Ribosomes?
(found in plant and animal cells)

Protein synthesis happens here

10

Function of cell wall?
(found in plant cells)

Strengthens the cell

11

Function of Chloroplasts?
(found in plant cells)

Contains chlorophyll, which absorbs light energy for photosynthesis

12

Function of Vacuole?
(found in plant cells)

Filled with cell sap to help keep the cell turgid

13

What is the order of organisation?

- Organelles
- Cells
- Tissue
- Organs
- Organ systems
- Organism

14

What is a tissue?

Group of cells with similar structures, working together to perform a shared function

15

What is an organelle?

Cell structure that is specialised to carry out a particular function or job

16

Function of cells?

Basic structural and functional unit of a living organism

17

Function of an organ?

Structure made up of a group of tissues, working together to perform specific functions

18

Function of an organ system?

Group of organs with related functions, working together to perform body functions

19

What is asexual reproduction?

Asexual reproduction only needs one parent. All the offspring are genetically identical to each other, and their parent. They are clones.

20

What is sexual reproduction?

Sexual reproduction needs two parents. Each parent produces sex cells, called gametes:
male gametes are called sperm
female gametes are called eggs S

21

What is fertilisation?

Fertilisation involves the fusion of a male and female gamete to produce a zygote that undergoes cell division and develops into an embryo
