cell structure

• The nucleus contains genetic information and controls the cell's activities.
• cytoplasm- where chemical reactions take place
• cell membrane- controls what enters and exits the cell.
• mitochondria- the site for aerobic respiration, energy is produced here
• ribosomes- responsible for synthesising proteins
• chloroplasts, vacuole and the cell wall are only found in plants
• chloroplasts- where photosynthesis takes place
• vacuole- filled with cell sap, helps to keep the cell turgid.
• cell wall- made of cellulose and provides structure and support to the plant
• cells can be either prokaryotic or eukaryotic.
• prokaryotes are single celled organisms, whose cells do not have a nucleus and contain extra pieces of smaller dna called plasmids.
