In vascular plants, phloem is the living tissue that transports the soluble organic compounds made during photosynthesis, in particular the sugar sucrose, to parts of the plant where needed
Phloem tissue consists of cells which include sieve tubes, parenchyma cells, companion cells, phloem fibres, and sclereids
Epithelial tissues
Form the outer surface of the skin and protect underlying cells from mechanical damage
Help in absorption, e.g. villi of the intestine
Help in secretion, e.g. salivary glands
Glandular epithelium
Made up of columnar or cuboidal cells specialized for secretion, sometimes forming multicellular glands
Glandular epithelium
Salivary gland
Thyroid gland
Muscle movement
Muscles work in pairs, one contracts while the other relaxes, allowing push and pull movement of the skeleton
Neuron
Structural and functional unit of the nervous system, specially adapted to carry electrical impulses or nerve impulses over large distances
Blood is a connective tissue composed of plasma, red blood cells, white blood cells, and platelets
Functions of blood
Transports gases, digested food, hormones and waste materials to different parts of the body
