IT’S A GREEN WORLD Who planted that there?

STARTER § Can you identify these trees? a. b. c. Oak Sycamore e. f. Horse Chestnut Birch d. Scots Pine g. Holly Ash h. Yew

Who planted that there? Learning outcomes § Explain how the cellular structure of a leaf is adapted for efficient photosynthesis Success criteria § You will be able to identify the different parts of a leaf and a plant cell. § Understand the process of photosynthesis

Lets start with the basics……………. The structure of a plant cell Cell wall – gives support Chloroplasts – where photosynthesis takes place Nucleus – controls cell function Vacuole – holds water and gives shape

Task § Now draw a fully labelled plant cell from memory (include the functions of the relevant parts).

How do plants get the food they need? All living organisms need food to grow and survive. Plants are known as producers because they provide food for many other organisms. Plants cannot move very much, so how do they get the food that they need?

Nutrition in green plants Green plants are amazing because they actually make their own food! Green plants are the only living organisms that are able to do this. All other organisms rely on plants because of the food that the plants make. What is the name of the process by which plants make their own food?

What is photosynthesis? Plants make their own food by photosynthesis. This process is a chemical reaction that uses light energy The word photosynthesis comes from the Greek language: l ‘photo’ means ‘light’ l ‘synthesis’ means ‘putting together’ Photosynthesis just means ‘putting together with light’.
