Can respiration occur if there is a lack of oxygen?
No, respiration cannot occur without oxygen. Oxygen is essential for the process of cellular respiration, which is the process by which cells break down glucose to produce energy. Without oxygen, cells are unable to generate energy efficiently and may not survive.
Could photosynthesis occur in a plant outside at night?
No, photosynthesis cannot occur at night because it requires sunlight to drive the process. Without light, the plant cannot convert carbon dioxide and water into glucose and oxygen. Photosynthesis only takes place during the day when sunlight is available.
Can cellular respiration occur without photosynthesis?
Yes, cellular respiration can occur without photosynthesis. Cellular respiration is the process by which cells break down glucose to produce energy, while photosynthesis is the process by which plants convert sunlight into energy. While photosynthesis provides the initial energy source for most living organisms, some organisms (like animals) rely on consuming other organisms for energy through cellular respiration.
Does Photosynthesis ceases in darkness?
Yes, photosynthesis cannot occur in complete darkness because it requires light energy to drive the process. Without light, plants cannot convert carbon dioxide and water into glucose and oxygen.
What does not occur in photosynthesis?
Cellular respiration does not occur in photosynthesis. Photosynthesis is a process where plants use sunlight to convert carbon dioxide and water into glucose and oxygen, while cellular respiration is the process where cells break down glucose to produce energy.
