Discuss and write down the 7 life processes.2. Is there a process that every organism does? Are some life processes more important than others? What is life?LO: to list the 7 life processes and define life

Are these alive?What life processes do they do?Malaria parasiteBacteriaIn pairs, decideAll do respiration and all composed of cells

Respirationis the process by which ALL cells obtain their energy. It is the burning of glucose sugar and oxygen to produce energy, carbon dioxide and water.Word Equation:Symbol Equation:is the process used by plant cells only to make glucose sugar (food) and oxygen using green chlorophyll, sunlight, carbon dioxide and waterPhotosynthesisWord Equation:Symbol Equation:glucose + oxygen => carbon dioxide + water

C6H12O6 + 6O2 => 6CO2 + 6 H2O

carbon dioxide + water => glucose + oxygen 6CO2 + 6 H2O => C6H12O6 + 6O2

Photosynthesis and respirationDuring the day, plants respire and photosynthesise.

At night, plants respire but dont photosynthesise. Plants respire to unlock the energy produced in photosynthesis, just as animals do. Respiration is the opposite of photosynthesis.At night, plants respire but dont photosynthesise. What could we have done to improve our pond weed experiment? Kept it in the darkWhy was our experiment with the pond weed unfair?

1. Give three reasons why a space alien may think that a motor car is a living thing (3)2. Give three reasons why you know that a motor car is NOT living (3)3. Discuss with your partner, can you think of something which are not cells but can cause disease? Are these alive?

These are pictures of viruses are they alive?HIV Coldsore virusCold virusFlu virusEbolaThey are not alive because they are not made of cells and dont carry out respiration

What colour will the hydrogen carbonate solution turn if I blow into it?I breathe out carbon dioxide from my respiring cells so the concentration of carbon dioxide will increase, the solution will turn yellowIncrease carbon dioxide= solution turns YELLOWDecrease carbon dioxide=solution turns PURPLEHydrogen carbonate solutionBicarbonate indicator turns purple if CO2 decrease and yellow if CO2 increases

ResultsLook at the boiling tubesFill in your results tableAre they all the same colour?Can you explain why some are different colours?In which one has the most respiration occurred and why?

OrganismBicarbonate indicator turns purple if CO2 decrease and yellow if CO2 increasesCopy the results table, discuss with your partner and try to predict the results

Are apples and mushrooms alive?

Is this what you expected, why not?

YES, becauseIf something respires to produce energy then it is aliveCELLS AND RESPIRATION = LIFEDo you kill an apple every time you eat one?

Which of these organisms respire?AEDCBFALL OF THEM!
