Structures in the cytoplasm where oxygen is used and most of the energy is released during respiration. 2 of 13 what are the structures found in an animal cell? nucleus, cytoplasm, cell membrane, mitochondria, ribosomes 3 of 13 why is the permanent vacuole important? keeps cell rigid to support the plant. 4 of 13 what is the cell level of organisation? cell, tissue, organ, organ system, organism 5 of 13 Give an example for the cell level of organisation. muscle cell, muscle tissue, stomach, digestive system, human body 6 of 13 what are organelles? Tiny structures which are packed inside cells and carry out a particular function. Found in cytoplasm of a cell. 7 of 13 why are enzymes important? the reactions that take place in the cytoplasm need to happen quickly which enzymes help them to do. 8 of 13 what does a root hair cell do? takes in water and mineral ions from the soil 9 of 13 what is the name given to a group of cells carrying out the same job? tissue 10 of 13 why do palisade cells have lots of chloroplasts? so they can absorb more of the sun's energy for photosynthesis. 11 of 13 what are specialised cells? specialised cells are adapted to carry out a particular function. 12 of 13 what is the definition of diffusion? when something travels from an area of high concentration to an area of low concentration. 13 of 13
