Animal cell

• Organisms are made up of cells.
• Most organisms are multicellular and have cells that are specialised to do a particular job.
• Microscopes are needed to study cells in detail.
• The basic structure of animal cells is the same as that of plant cells.
• Mitochondria are structures in the cytoplasm of all cells where aerobic respiration takes place.
• Ribosomes are the site of protein synthesis and are only visible with the electron microscope.
• Cytoplasm is a jelly-like material that contains dissolved nutrients and salts and structures called organelles.
• The nucleus contains genetic material, including DNA, which controls the cell’s activities.
• The cell membrane is permeable to some substances but not to others, controlling the movement of substances in and out of the cell.
• Mitochondria are organelles that contain the enzymes for respiration, and where most energy is released in respiration.
• Ribosomes are tiny structures where protein synthesis occurs.
• Most cells are specialised and are adapted for their function, meaning animals and plants consist of many different types of cell working together.
