Some of the cells are specialised for different functions in the organsim 22 of 33 muscle tissue the tissue which makes up the muscles. It can contract and relax 23 of 33 nucleus an organelle found in many living cells containing the genetic information 24 of 33 organ system a group of organs working together to carry out a particular function 25 of 33 permanent vacuole a space in the cytoplasm filled with cell sap that is there all the time 26 of 33 phloem the living transport tissue in plants which carries sugars around the plants 27 of 33 protein synthesis the process by which proteins are made on the ribosomes based on information from the genes in the nucleus 28 of 33 ribosome the site of protein synthesis in a cell 29 of 33 salivary gland gland in the mouth which produces saliva containing the enzyme amylase 30 of 33 small intestine the region of the digestive system where most of the digestion of the food takes place 31 of 33 specialised adapted for a particular function 32 of 33 xylem the non-living transport tissue in plants, which transports water around the plant 33 of 33
