CELLS

Cells are the BASIC UNITS OF LIFE. All living things are made up of CELLS.

THE THREE BASIC LIFE PROCESS

NUTRITION

REPRODUCTION

SENSITIVITY

NUTRITION. Cells obtain nutrients and energy from food.

REPRODUCTION. Cells divide and produce new cells that are identical to themselves.

SENSITIVITY. Cells react to what they perceive around them.

ANIMAL CELL

Organelles

MEMBRANE: Control what enters and leaves

the cell. It‘s the covering around the cell.

NUCLEUS: It controls the cell.

CYTOPLASM: It’s the liquid inside the cell. It

contains the organelles, which carry out

different functions of the cell.

LEVELS OF ORGANIZATIONCells in multicellular living things are organised in levels – LEVELS OF ORGANIZATION.

Cells are specialised:

they have specific

functions.

Cells form tissues. Tissues are

groups of cells with the same

function.

Tissues form organs. Organs are groups of

various tissues which act together.

Organs form systems. Systems are made up of several organs

ANIMAL TISSUE

BLOOD TISSUE – (it’s made up of blood cells). It carries SUBSTANCES

throughout the body.

MUSCLE TISSUE – (it’s made up of muscle cells). It is responsible

for MOVEMENT.

BONE TISSUE – (it’s made up of bone cells). It

forms bones and supports the body.

NERVOUS TISSUE – (it’s made up of NEURONS). It carries INFORMATION

to the BRAIN.

FAT TISSUE – (it’s made up of FAT cells). It is

specialized in STORING FAT.

EPITHELIAL TISSUE – (it’s made up of epithelial cells). It forms the skin

and provides protection to the body.

PLANT TISSUEDERMAL TISSUE covers the leaves

and provides protection.

GROUND TISSUE provides support, stores nutrients and performs

photosynthesis.

VASCULAR TISSUE is found in the xylem and phloem vessels. It

transports substances.
