in multicellular organisms are modified to carry out a particular function, such as transporting a certain substance or executing a specific task
2 of 12
red blood cell
transports oxygen from the lungs to the tissues where aerobic respiration occurs, and the cytoplasm is filled with the pigment haemoglobin which carries oxygen
3 of 12
muscle cell
contracts so that structures can be Brough closer together, and they are long and have many protein fibres in the cytoplasm, which can shorten the cell when energy is available
4 of 12
ciliated cell
has a later of tiny hairs (cilia) which can move and push mucus from one place to another
5 of 12
motor nerve cell
conducts nerve impulses, and has a long fibre called an anon along which impulses travel, a fatty sheath which fives electrical insulation, and a many-branched ending which can connect with many other cells
6 of 12
epithelium
lines tubes such as the gut and covers surfaces such as the skin
7 of 12
connective tissue
binds and strengthens other tissues
8 of 12
blood
transports substance around the body and defends against disease
9 of 12
nervous tissue
supports and protects softer tissues and allows movement
10 of 12
muscle tissue
contracts to support and move the body
