  • Name one thing that the leaves do?
    They make food for the plant with water, minerals, air, and sunlight
  • Name two things that the stem does?
    It holds up the plant. It connects the roots and the leaves so that water, minerals, and nutrients pass through it.
  • True or False: Plants aren't living things because they don't move around
    False: They are living things because they perform the three life processes (nutrition, interaction, reproduction)
  • What type of stem does grass have?
    A flexible, green stem (usually short)
  • What things do plants produce with photosynthesis?
    They produce food + oxygen
  • How do insects help plant reproduction?
    They take pollen from one flower to another. Then, that pollen goes inside the pistil and joins an ovule to make a seed
  • True or False: All plants perform reproduction
    True: They are all living things, so they all reproduce; but some do it in different ways
  • What is the name of the female reproductive organ in flowers?
    The pistil
  • What do flowers need the calyx and sepals for?
    To protect themselves
  • What are the three types of plants we classify by their stems?
    Trees, bushes, and grasses
  • What type of stem does a tree have?
    One big woody stem, called a trunk
  • Name two things that the roots do?
    They absorb water and minerals from the soil. They fix the plant in the soil
  • What four things do plants need to perform photosynthesis?
    They need minerals + water + sunlight + carbon dioxide
  • What do flowers need petals for?
    They attract insects with bright colours to help pollinate.
  • What is an evergreen plant?
    A plant that always has leaves, even in winter
  • What are the two types of plants we classify by their leaves?
    Evergreen and deciduous
  • What happens inside a flower when they make a seed?
    The petals fall off the flower and the pistil grows around the seed into a fruit. Then, the fruit falls on the ground and the seed grows into a new plant
  • What is a deciduous plant?
    A plant that loses its leaves in autumn and grows new ones in spring
  • What are two ways we use plants in our daily lives?
    For food (we eat fruits and vegetables), for medicines, for cosmetics (perfume, soap, makeup), and for making different materials (wood, paper, rubber)
