Knowledge organiser - Plants - Year 3

The Year 3 science curriculum introduces students to the fascinating world of plants, equipping them with essential vocabulary and key knowledge about plant biology. One of the critical processes they learn about is pollination, which involves the transfer of pollen grains from the male anther of a flower to the female stigma. Another important concept is seed dispersal, the process by which seeds are transported away from the parent plant to facilitate the spread of the species. Students also explore seed formation, understanding that a seed is essentially a tiny, immature plant encased within a protective seed coat and often accompanied by stored food to support early growth.

Nutrients are highlighted as essential sustenance for plants, with most of them being absorbed from the soil. The parts of a flower are also studied, including the stigma, which is typically sticky to capture pollen, and the anther, which is the part of the stamen responsible for producing pollen. As for the key knowledge, students are expected to comprehend what plants need to thrive and to learn about their life cycle. They should be able to identify different parts of a flowering plant and their functions, recognize the importance of light, air, water, and soil nutrients for plant growth, and understand how water is transported within plants. Additionally, they delve into the role of flowers in the life cycle of flowering plants and the processes of pollination, seed formation, and seed dispersal, all of which are fundamental to plant reproduction.
