Bioenergetics Photosynthesis
What do you think the key words are for todays lesson?
Lesson Objectives Lesson Competency (Level 1-3) Proficiency (Level 4-6) Mastery (Level 7-9) 1 Write the word and symbol equation for photosynthesis Explain why photosynthesis is important for the survival of other organisms. Explain why the leaves are tested for starch and not for sugar.
What organ does what? To pump blood To break up food and absorb it To clean blood and make urine To break up food To control the body For protection and feeling To remove water from unwanted food For breathing To make and destroy substances
Plants have organs too! What are the four main organs of a plant?
Use the information cards to fill in the table below; Organ Function Drawing Stem Leaf Flower Root
What is the function of the stem? The stem helps to support the plant. It also carries water and food around the plant.
What is the function of the leaves? The leaves use sunlight to provide the plant with energy.
What is the function of the flower? The flower helps the plant to reproduce.
What is the function of the roots? The roots absorb water, nutrients from the soil. They also keep the plant in the soil!
Would there be life on earth if there were no plants? If there was life, what would life be like?

Photosynthesis
Copy the note below, filling in the blanks The word nutrition describes the process by which an organism gets its food Plants make their own food in a process called photosynthesis Plants use energy from sunlight to build sugars from water from the soil and carbon dioxide from the air. Most plants store their sugars as starch energy from SUNLIGHT water + carbon dioxide glucose + oxygen CHLOROPHYLL
What s the point of a greenhouse?
Who s going to photosynthesize more?
What factors affect photosynthesis? Temperature Light Intensity CO2 Concentration
What do all leaves have in common?
Stomata is where the carbon dioxide enters and oxygen exits the leaf
How are leaves adapted for photosynthesis?
What is the function of the root? What is produced in photosynthesis? What is the function of the flower? How do leaves get water? What is the equation for photosynthesis? What are the holes under the leaves called? What is the function of chlorophyll? Why are leaves thin? Why are leaves broad?
The thing I have found most difficult in this lesson so far The most important thing I ve learned so far I did not know but now I know and I know this because I have learned several new things about this topic. Firstly Furthermore A question that I have about today s lesson so far So far I have been successful in my learning because New science key words I have learned Two new facts about what I have learnt so far which I will tell someone are... So far in this lesson I have tried I can now make links to I feel confident about my progress in this lesson because A golden rule that I will remember One thing I need to remember from the work I have completed so far
