Biology – Assignment One Cells. Question One Explain the roles of the main components and features of a cell to the cell function. A typical animal cell is rounded in shape‚ surrounded by a cell membrane. This holds in the cytoplasm‚ which contains other structures such as the nucleus‚ ribosomes‚ and mitochondria. Each cell has tiny structures inside called organelles; each type of organelle performs a particular function. For example there are mitochondria (power stations)‚ ribosomes (protein

Cells and Movement of Substances All living things are formed by cells‚ the structure of these cells varying depending on their function. Animal and plant cells have common features such as a nucleus‚ cytoplasm and cell membrane. Dissolved substances pass into and out of cells by diffusion Diffusion Diffusion definition: Diffusion is the movement of molecules from a high concentration to a low concentration. Dissolved
Premium Protein Organelle Cell
animal cell is not visible to the naked eye and is about 10 to 30 micrometers. A micrometer is one one-thousandth of a millimeter. They are so small that it takes a microscope with a magnification of at least 400x to be able to see inside the cell. These cells are what make up the basic units of structure and function in all living things. They carry out our life processes and make it possible for us to function and live. Inside these cells are organelles‚ which are smaller than the cell itself.
