Add Science: Biology - B2a 0.0 / 5 ? Applied ScienceB2aGCSEAQA Created by: el_watson16Created on: 08-10-16 19:07 What is the function of ribosomes? Where proteins needed for the cell are synthesised 1 of 25 Which types of cells are ribosomes found in? Animal and Plant 2 of 25 What are bacteria (in terms of cells)? Unicellular organisms that are microorganisms 3 of 25 What is the function of the vacuole? Contains cell sap that helps to keep cell rigid to support plant 4 of 25 What happens in mitochondria? Energy is released during respiration 5 of 25 What doesn't a bacteria cell have and so what does this mean? Nucleus so the genetic material is in the cytoplasm 6 of 25 What is the function of plasmids in a bacteria cell? Small circles of DNA that also contain genes to make protein 7 of 25 If a cell has many mitochondria, what does this mean? It must need a lot of energy 8 of 25 Many ribosomes? It is making a lot of protein 9 of 25 Why are cells specialised? So that they can carry out a particular function 10 of 25 What is the function of a muscle cell? Contracts to allow movement of body parts 11 of 25 How is a muscle cell adapted? It contains long protein filaments that can lie past each other to shorten the cell 12 of 25 What is the function of a guard cell? To open and close stomata 13 of 25 What does epithelial mean? A cell that covers or lines something 14 of 25 What is a tissue? Lots of specialise cells working together 15 of 25 What is diffusion? Spreading out of particles of a gas or any substance in a solution 16 of 25 What does the net movement depend on? The concentration of particles on each side of the cell membrane 17 of 25 What happens in diffusion? Particles move randomly from an area of high concentration to an area of lower concentration 18 of 25 What is the concentration gradient? The difference between the two areas. 19 of 25 The larger the concentration gradient... the faster the rate of diffusion 20 of 25 Explain cells These differentiate during the development of organisms so that they can perform certain functions 21 of 25 Tissue Group of cells working together to perform a certain function 22 of 25 What is the function of epithelial tissue? Make up linings and cover some parts of the body 23 of 25 Function of glandular tissue? Produce substances such as enzymes or hormones and then to release them 24 of 25 Function of muscular tissue? Contact to bring about movement 25 of 25
