Key Vocabulary
petalThe outside part off the flower head that attracts insects
stamenThe male reproductive part of the flower
antherThe part of the stamen that contains the pollen
pistilThe female reproductive part of the flower
stigmaThe part of the pistil that receives the pollen
ovaryThe part of the plant that contains the ovules (eggs)
pollination
The process by which pollen is transferred to the female part of the plant so it can make seeds and reproduce
fertilisationWhen pollen joins with the ovule, a new seed is created
seed dispersalThe movement or transport of seeds away from the parent plant
pollenThe product of the male part of the plant which allows new seeds to be made
nutrientsA substance that provides nourishment for growth
rootsThese anchor the plant in the ground and absorb water and nutrients from the soil
stemThis transports water and nutrients to different parts of the plant
leavesThe place where photosynthesis takes place
photosynthesisThe process by which plants use sunlight to make food
Key Questions
What do I already know about plants?
I know the names for the different parts of the plant such as roots, stem, leaves and flowers. I can describe how plants need water, light and a suitable temperature to grow and stay healthy.
How do plants feed?
The roots take water and nutrients from the soil. These travel through the stem of the plant to the leaves. The leaves mix this with sunlight and carbon dioxide, absorbed through the leaves, and make this into food. This is called photosynthesis.
What is pollination?
For a plant to grow a new seed, pollen from one plant needs to get to the egg of another plant. This transfer might be by the wind or by insects such as bees.
How do new seeds form in the plant?
When the pollen joins the egg from the ovary of a new flower a seed or many seeds are formed.
How do new seeds get into the soil to grow?
Seeds might be dispersed by: - Wind (e.g. dandelion seeds) - Animals (seeds are eaten and then pooped out) - Explosion (dry seed pods split open and shoot out the
seeds)
Plants - Y4To be able to identify and describe the functions of different parts of flowering plants: roots, stem, leaves and flowers. To be able to explore the requirements of plants for life and growth (air, light, water, nutrients from soil and room to grow) and how they vary from plant to plant. To be able to investigate the way in which water is transported within plants. To be able to explore the part that flowers play in the life cycle of flowering plants, including pollination, seed formation and seed dispersal.
