Summary for Respiration in Plants MCQ Quiz
Plants breathe differently than animals. They don’t have special breathing organs. Instead, they use tiny holes in their leaves (stomata) and stems (lenticels) to exchange gases. Most plant cells are close to air, making gas exchange easy.
Cellular respiration is how living things break down food for energy. It happens in these steps:
- Glycolysis: This happens in the cell’s main part. It breaks down sugar into smaller molecules, releasing some energy.
- Fermentation: When there’s no oxygen, cells can still make some energy this way. This process makes alcohol or lactic acid.
- Aerobic respiration: When oxygen is present, cells can make much more energy. This happens in special parts of the cell called mitochondria. It involves a complex series of chemical reactions that produce a lot of energy.
The type of food (like sugar, fat, or protein) used for energy affects how much oxygen is needed and how much carbon dioxide is produced.
