Define tissue A tissue is a group of similar cells eg muscle tissue, nervous tissue

Some animal tissues Muscle, bone, connective, nervous tissue

Plant tissues Dermal tissue Vascular Tissue A single layer of cells that surrounds the different parts of a plant Epidermis protects the plant Vascular Tissue Transports materials around the plant Xylem transports water and minerals around the plant Phloem transports food from the leaves to the other parts of the plant

7. Define organ Several different types of tissue organised together for a particular function e.g. heart, leaf, liver
