    It must have a large surface area over which the gases can diffuse. A large surface area maximises the amount of area available for the gases to exchange. It must also be moist. Oxygen must first dissolve into a fluid before it can diffuse into a cell. Having a moist gas exchange surface ensures the gases can be dissolved. Thirdly‚ the membrane through which gases diffuse must be thin. Gas exchange is driven by concentration gradients. Diffusion is the process which moves the gases. The rate of

    diploid cells. Tell where in an organism they are found. Tell how they are produced. A haploid cell is a cell that contains one complete set of chromosomes. Gametes(sperm and ova) are haploid cells that are produced by meiosis. Diploid cells contain two complete sets (2n) of chromosomes. Diploid cells reproduce by mitosis making daughter cells that are exact replicas. Some examples are skin‚ blood‚ muscle cells (also known as somatic cells). 2. In 2-4 sentences compare and contrast mitosis and meiosis
