  • What four things do plants transform into nutrients during photosynthesis?
    sunlight, water, mineral salts, carbon dioxide
  • What controls everything that happens inside the cell?
    nucleus
  • What is the function of the circulatory system?
    The circulatory system helps us carry out nutrition as it transports oxygen and nutrients to and from cells.
  • Label theses 5 parts of a plant cell.
    1. chloroplasts 2. cell wall 3. nucleus 4. vacuole 5. membrane
  • Which four systems do animals use to carry out nutrition? What are the functions of these four systems?
    Digestive: extracts nutrients from the food. Respiratory: absorbs oxygen. Circulatory: transports nutrients around the body. Excretory: expels waste products.
  • What type of cell can swim?
    Male reproductive cells can swim.
  • What is the vascular system?
    It is composed of different tissues that transport water, mineral salts and nutrients around the plant.
  • Which substance in a plant cell helps carry out photosynthesis?
    chlorophyll, membrane, cell wall, chloroplast
  • Plant tissues play 3 specific roles. What are they?
    1 Protection 2 Transportation of nutrients 3 Supporting the plant

  • Plant cells have a ____________ cell wall.
    rigid
  • What do red blood cells do?

  • Muscle tissue is _______ but _______ so that the muscle can expand and contract easily.
    strong, hard
    hard, strong
    strong, flexible
    flexible, strong
  • What are the functions of the leaves, roots, and stems in plants?
    Leaves: make food for the plant. Roots: absorb water and nutrients from the soil. Stems: support the plant and transport water and nutrients throughout.
