The basic building block of all living things 1 of 22 Which 3 features do animal and plant cells have in common? A nucleus, cyptoplasm, cell membrane 2 of 22 What additional features to plant cells have? Rigid cell wall, vacuole, chloroplast 3 of 22 What is function of the nucleus of a cell? It controls all the activities of the cell. 4 of 22 What is the function of cytoplasm in cells? It is a gel-like substance where chemical reactions happen 5 of 22 What is the function of the cell membrane? It holds the cell together and controls what enters and what leaves the cell 6 of 22 What is the function of a plant's cell wall It supports the cell and strengthens it 7 of 22 What is a vacuole? It is a large space in a plant cell containing cell sap 8 of 22 What is a choloroplast? It is a structure in a plant cell where photosynthesis happens. 9 of 22 What is the process by which cells become specialised for a particular job. Differenciation 10 of 22 Define the term tissue A tissue is a group of cells with similar structure and function 11 of 22 Name 3 types of tissue Muscular - contracts to bring about movement, Glandular - produces hormones and enzymes, Epithelial - covers some parts of the body 12 of 22 What is an organ? Different types of tissues that work together to perform a particular function 13 of 22 What tissues are the stomach made up of? Muscular to churn up the food, glandualar to make digestive juices to digest food, epithelial which covers the inside and outside of the stomach 14 of 22 What is an organ system? A group of organs working together to perform a particular function e.g. digestive system which breaks down food 15 of 22 What organs is the digestive system made up of? Mouth, salivary glands, oesophagus, stomach, pancreas,small intestine, liver, gall bladder, large intestine, rectum, anus 16 of 22 What does the digestive system do? It breaks up large insoluable food into small soluble food allowing abssorption into the blood. 17 of 22 Which organ produces bile? Liver 18 of 22 Give two roles that bile plays in digestion? It neutralises acid for enzymes in the small intestine to work more efficiently, improves fat digestion 19 of 22 Where is bile stored before it is released into the small intestine? Gall bladder 20 of 22 Give 3 reasons why the supply of organs for transplan are limited? Correct tissue matching, size and age. 21 of 22 Following an organ transplant, why are drugs given to the patient to suppress the immune system? The drugs prevent the organ being rejected by the body, the immune system will not produce antibodies against the new 'foreign' tissue. 22 of 22
