cells and stem cells

• This is an animal cell

  
• This is a plant cell

  
• This is a bacteria cell

  
• cytoplasm-where chemical reactions take place
• role for the nucleus?


  contains genetic information and controls the activity of the cell
• cell membrane-controls what goes in and out of the cell
• cell wall- supports the cell and strengthens it
• mitochondria-where aerobic respiration takes place.Respiration transfers energy the cell needs so it can work
• ribosomes-where proteins is made
• permanent vacuole-contains cell sap and a weak solution of sugar and salts
• chloroplasts-where photosynthesis occurs which contains chlorophyll which has a green pigment which absorbs light
• what are undifferentiated cells/stem cells?


  cells that can divide to produce more undifferentiated cells.
• where are adult stem cells found?

  adult stem cells are found in places like bone marrow but adult stem cells cannot turn into any type only certain ones like blood cells
• can embryonic stem cells turn into any type of cell?


  yes
• what is differentiation?


  process of a cell changing to become specialised
