Think, pair, share Why do we use these? How do plants move and use the products the make in photosynthesis?

Proteins – complete Proteins are important for plants to form ………, leaves and ………. Plants do not eat so have to…….their own nutrients. Plants get …………from the soil which are dissolved in ………………. They turn these into proteins in their cells. WORDS Chlorophyll, nitrates, water, make, roots How do plants move and use the products the make in photosynthesis?

Lets investigate – complete the following Investigation: starch in fruit and veg. Take samples of a range of fruit and veg. Test for starch. Make a conclusion (PEE) P: Which of the samples you tested, had the most/ least starch? E: How do you know? E: Use the information provided to write an explanation to support this. How do plants move and use the products the make in photosynthesis?

Experiment 2 – leaves from light / dark Conclusion: PEE Which of the samples had no starch? How do you know? Use the information provided to write an explanation to support this. How do plants move and use the products the make in photosynthesis?

QUESTION REVEAL Will you get an easy or a hard one?5 points / question. : Which process makes glucose in a plant? Where do plants get water from? What is the equation for photosynthesis? If you join lots of glucose together, what do you get? What is the equation for respiration? What does the xylem vessel carry? What is 185 x 2 What is the green substance found in chloroplasts? What does the phloem vessel carry? How do plants move and use the products the make in photosynthesis?

Check point, which way will the particles move? molecule How do plants move and use the products the make in photosynthesis?

What is the inside of a leaf like? How do plants move and use the products the make in photosynthesis?

Use the information to label and annotate the diagram. Stomata are a hole through which gases can enter and leave the leaf. Oxygen and carbon dioxide can freely move by diffusion through these holes when they are open, however, their movement is halted when the stomata are closed. This occurs when a plant has too little water and the guard cells collapse in, pressing together and closing the hole. This prevents the plant from becoming dehydrated and losing further water through evaporation. There are two guard cells for each stomata. At the top and bottom of the leaf there is a waxy cuticle which prevents the leaf from becoming burned or dehydrating. Below the cuticle is the upper epidermis and below this the palisade layer, which contains long cells with a large amount of chloroplasts. Further down again, is the spongy mesophyll which contains large air gaps in order for the gases made and used, to move around the leaf. The palisade layer and spongy mesophyll are collectively called the “mesophyll tissue.” Finally there is the vascular structure of the leaf which contains the xylem and phloem vessels, which carry water and food respectively.

Getting Gases In – lets investigate Aim: to observe and draw stomata. Method: 1) Paint the underside of a leaf with clear nail varnish. 2) Leave to dry 3) Peel off nail varnish 4) Observe under microscope and draw what you see. How do plants move and use the products the make in photosynthesis?

Check Point – what is the job of the stomata? To allow gas exchange to occur. To let oxygen out To allow a plant to breathe. For a plant to get water How do plants move and use the products the make in photosynthesis?
