Revise: Producing new cellsAnimal and plant tissues
Cell division allows for growth and replacement of dead cells. Most multicellular organisms are made of different cell types that are specialised to carry out specific functions.
Groups of specialised cells that carry out particular functions are called tissueA group of similar cells that carry out the same function, eg muscle tissue..
The table gives some examples of animal and plant tissues.
Tissue
Present in animal or plant
Function
Blood (connective tissue)
Animal
Transports oxygen, dissolved food, carbon dioxide and many other substances around the body
Cartilage (connective tissue)
Animal
Acts as a cushioning material between bones. Supports airway tubes in the lungs.
Muscle
Animal
Can contract to allow movement of body parts
Nerve
Animal
Allows rapid communication between different parts of the body
Phloem (vascular tissue)
Plant
Transports dissolved sugars from the leaves to growth points
Xylem (vascular tissue)
Plant
Transports water and mineral salts from roots to leaves
