cell structure

• ribosomes

  site of protein synthesis
• mitochondria

  site of aerobic respiration in the cell
• cell wall

  layer of support to give cell extra strength
• chloroplasts

  carry out photosynthesis, contain pigment chlorophyll
• how is mitochondria represented in diagram

  line that are widthways and often wiggly
• chloroplasts on diagram

  no lines or straight lines lengthways
• nucleus

  contains genetic information of the cell, surrounded by it's own membrane
• cytoplasm

  thick watery liquid where chemical reactions take place and where other organelles are found
• cell membrane

  surrounds cell, keeps all organelles inside and controls movement of substances in and out of the cell
• vacuole

  large organelle in centre of plant cell and small, temporary one in some animal cells. surrounded by a membrane filled with fluid (cell sap) for plants
• which organelles are only plants and not animals

  chloroplasts, cell wall, permanent vacuole
