Biology Revising P2 Ch2 Ch3 P26-34

Front 1

MOVEMENT

Back 1

All organisms are able to move to some extent.Most animals can move their whole body from place to place, and plants can slowly move parts of themselves.

Front 2

EXCRETION

Back 2

All organisms produce unwanted or toxic waste products as a result of their metabolic reactions, and these must be removed from the body.

Front 3

SENSITIVITY

Back 3

All organisms pick up information about changes in their environment, and react to the changes.

Front 4

REPRODUCTION

Back 4

Organisms are able to make new organisms of the same species as themselves.

Front 5

GROWTH

Back 5

All organisms begin small and get larger, by the growth of their cells and by adding new cells to their bodies.

Front 6

RESPIRATION

Back 6

All organisms break down glucose and other substances inside their cells, to release energy that they can use.

Front 7

NUTRITION

Back 7

Organisms take substances from their environment and use them to provide energy or materials to make new cells.

Front 8

cell membrane

Back 8

it controls what goes in and out of the cell.

Front 9

cell wall

Back 9

this helps to protect and support the cell. it is made of cellulose.

Front 10

cytoplasm

Back 10

liquid inside the cell with different metabolic reactions. It is made of 70% water and proteins.

Front 11

Vacuoles

Back 11

helps to keep the cell in shape. Inside is water, sugar and other substances.

Front 12

chloroplast

Back 12

it is doing photosynthesis. It is made of chlorophyll.

Front 13

Nucleus

Back 13

Nucleus helps the cell to make the right sorts of proteins. It is made of genetic information,chromosomes,DNA.

Front 14

ribosomes

Back 14

ribosomes make proteins.

Front 15

osmosis

Back 15

The diffusion of water molecules from a region of higher water potential to a region of lower water potential, through a partially permeable membrane.
