• A cell are divided into unicellular and multicellular organisms
• Multicellular organisms are plants and animals
• A cell is tissues, organs, systems and organisms.
• What does a animal cell not have?

  chloroplast and cell wall.
• What is a unicellular organism?

  Organisms that contain only one cell
• What is a multicellular cell?

  A organism that consists more than one cell
• A animal and plant cell both contains?

  vacuole, nucleus, cytoplasm, cell membrane
• What will happen to a plant cell if there is no nucleus?

  It will die
• What are the functions of a nucleus?

  It contains DNA which would help pass on genetic info and controls all the cells activities.
• Cytoplasm is where?

  most chemical reactions take place
• Cell membrane allows?

  only certain substances to pass through
• A function of the cell membrane is?

  controlling the movement in and out of the cell
• A vacuole does?

  store liquids, food, waste materials
• A animal vacuole?

  has small and numerous vacuoles
• The chloroplast is surrounded by?

  a double membrane
• A plant vacuole?

  one large central vacuole
• A chloroplast is?

  surrounded by a double membrane
• the double membrane is?

  the inner and outer cell membrane
• a chloroplast?

  contains chlorophyll to absorb light for photosynthesis
• cell wall?

  gives the plant cell a regular shape and protects the cell from injuries
