Respiration

Transcript

What is Respiration?It is a process by which living things produce energy from food It is done by breathing in Oxygen and taking out Carbon Dioxide Example Human Beings breathe through Nose This helps breaking down food to get energy Do plants also do Repiration?Yes, Plants take in Oxygen through tiny pores on leaves Break down food Release energy and give out Carbon Dioxide DifferenceANIMALS They do Respiration Take in Oxygen and Give out Carbon Dioxide To breakdown food They do Respiration Take in Oxygen and Give out Carbon Dioxide To breakdown food They also do Photosynthesis Take in Carbon Dioxide and Give out Oxygen To make food Plants give Oxygen, so how do they respire ?During daytime (plants do both) Photosynthesis - takes CO₂, gives O₂ Respiration - takes O₂, gives CO₂ Photosynthesis is much Faster, so: Net Result = Oxygen Comes out During Night (no sunlight) Photosynthesis stops Respiration continues Plants takes in Oxygen Plants gives out Carbon Dioxide ComparisonPHOTOSYNTHESIS RESPIRATION Photosynthesis is the process by which green plants make food using sunlight, carbon dioxide, and water. Happens during Sunlight only Green plants only to Make food By taking in Carbon Dioxide Taking out Oxygen Respiration is the process by which energy is released from food All organisms do Respiration Happens all time by all plants and animals to Release energy from food By taking in Oxygen Taking out Carbon Dioxide Green Plants do Photosynthesis
