BiologyCellular processes and structureInternational BaccalaureateNone Created by: RPCreated on: 13-05-13 20:28 What orgenelles do a animal cell have? cytoplasm, nucleus, cell membrane 1 of 23 What orgenelles do a plant cell have? cytoplasm, nucleus, cell membrane, permanent vacuole, chloropasts,cell wall 2 of 23 Name the specialised cells. Blood cell, Egg cell, Sperm cell, Ciliated Epithelial cell, Root hair cell, Nerve cell, Palisade cell 3 of 23 Job and where the blood cell is found Designed to carry oxygen, found in blood stream. 4 of 23 Job and where the egg cell is found Designed to be fertilised, found in blood. 5 of 23 Job and where the sperm cell is found Designed to fertilise eggs, found in testes. 6 of 23 Job and where the ciliated epithelial cell is found Designed to stop lung damage, found in air passages in the lungs. 7 of 23 Job and where the root hair cell is found Designed for absorbing, found on the tip of roots. 8 of 23 Job and where the nerve cell is found Designed to carry nerve impulses to different parts of the body. 9 of 23 Job and where the palisade cell is found Designed for photosynthesis, found on the top part of leaves. 10 of 23 Detail for red blood cells. Has no nucleus so it can carry haemoglobin. It is bioconcave 11 of 23 Detail for egg cells. Contains yolk which provides a large food store for the new cell 12 of 23 Detail for sperm cells. Small with a long tail so it can swim. Head has enzymes to digest egg cell. 13 of 23 Details for ciliated epithelial cell. Tiny hair called cilia sweep trapped dust and bacteria back up the throat. 14 of 23 Details for palisade cell. Large surface area to absorb water and minerals. Packed with chlorplasts to make plant food. 15 of 23 Details for root hair cell. Large surface area to absorb water and minerals. 16 of 23 Details for nerve cell. They have connections at both ends. Can carry electrical signals. They are long. 17 of 23 Nucleus Controls what the cell does. Stores all the information in a coded form called DNA found in chromosomes. 18 of 23 Cytoplasm Jelly like substance that fills the cell where chemical reations happen. 19 of 23 Cell Wall Covers the membrane and gives strength to plant cell. 20 of 23 Cell Membrane Thin layer that surrounds the cell. Controls what chemicals enter and leave. Can break if too much strain is on it. 21 of 23 Chloroplasts Structures containing the green pigment chlorophyll. Absorbs light energy to make food for plants. 22 of 23 Vacuole Stores water in a plant cell. Gives colour to the cell. 23 of 23
