9C On the farm

Sun, soil and air
Describe how leaves are adapted to the job they do. Describe how roots are adapted to the job they do. Recall why plants need water. Identify the different specialised cells in plants and explain their adaptations.

 * Activities **
 * 1) Which are the three main parts of a plant and what are their functions (optional activity - a simple discussion might be enough). Complete the [[file:ES9_Cb034_02msu.doc|worksheet]] to summarise.
 * 1) Look at the animation showing water transport through a plant
 * 1) Investigate [[file:ES9_CHAP_Cb3.pdf|water transport in celery stems]]
 * 1) How are leaves adapted for photosynthesis? Look through the animation to find out
 * 1) Complete the [[file:ES9_CHAP_Cb6.pdf|worksheet on leaf adaptations]]
 * 1) Can you find stomata on a leaf? Collect a leaf and follow the instructions to see the stomata under a microscope (IG link)
 * 1) Complete Q1-10 from p34-5 of Exploring Science 9
 * 1) Watch the video showing gas exchange and discuss what is happening
 * 1) Review gas exchange using BBC Bitesize in plants and the balance between photosynthesis and respiration.
 * 1) Look back at your Waterweed experiment. Discuss any changes you see and suggest what they mean. Follow your teacher's guidance to draw and annotate what you have found out.
 * 1) Extension: Look at gas exchange in plants in more depth? Read and answer the questions on the worksheet
