1 00:00:06,700 --> 00:00:10,699 All living things are made up of cells. 2 00:00:10,699 --> 00:00:13,699 Cells are the basic units of life. 3 00:00:13,699 --> 00:00:17,699 The nucleus controls everything that happens inside the cell. 4 00:00:17,699 --> 00:00:20,699 It controls the cell's activities. 5 00:00:20,699 --> 00:00:23,699 The membrane surrounds and protects the cell. 6 00:00:23,699 --> 00:00:27,699 The nucleus and the cytoplans are found inside the membrane. 7 00:00:27,699 --> 00:00:33,700 It also controls what goes into and out of the cell. 8 00:00:33,700 --> 00:00:40,700 The Zeta flange is a tree clear liquid protected by the membrane. 9 00:00:40,700 --> 00:00:50,700 It is composed mainly of salt and water and contains all the organelles outside the nucleus. 10 00:00:50,700 --> 00:00:59,700 Buccleaux are types of organs. Animal cells have several small bucleaux. 11 00:00:59,700 --> 00:01:04,700 Each of the specialist organelles carry out different life processes. 12 00:01:05,700 --> 00:01:12,700 They carry out nutrients by transforming nutrients into energy. 13 00:01:13,700 --> 00:01:19,700 Plants and animals are different shapes and have different components, 14 00:01:19,700 --> 00:01:25,700 but most cells have a nucleus, a membrane, cytoplasm and organelles. 15 00:01:25,700 --> 00:01:32,700 Plant cells have a rigid cell wall around the membrane. This helps support the plant. 16 00:01:32,700 --> 00:01:45,700 Plant cells have a large vacuole. In it is a storage bubble that contains water and nutrients or sometimes waste products. 17 00:01:45,700 --> 00:01:54,700 In the cytoplasm of plant cells, there are special organelles called chlorophylls. 18 00:01:54,700 --> 00:01:58,700 They contain a green substance called chlorophyll. 19 00:01:58,700 --> 00:02:03,700 This liquid helps to carry out photosynthesis.
