During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds. How does photosynthesis occur? Photosynthesi
Plants cannot perform photosynthesis in the absence of sunlight. If photosynthesis does not occur, plants cannot prepare starch, and they eventually die. Autotrophic plants contain a green pigment called chlorophyll, which is necessary for photosynthesis. Chlorophyll traps heat from sunlight and initiates...
Why is photosynthesis considered a chemical reaction? Why can't photosynthesis occur in the disphotic zone? Why are nutrients important to living organisms? Why is water split during photosynthesis? Why is sunlight important for the biosphere? Why are plants important to the carbon cycle? Why are...
Discuss why plants have two types of chlorophyll instead of just one. How does this benefit them? What would you expect concerning the rate of photosynthesis for a plant that had only one type of chlorophyll? Explain why plants will not photosynthesize in the dark. ...
问:“What is photosynthesis?”(什么是光合作用?) 答:“A process by which plants convert sunlight into energy.”(植物将阳光转化为能量的过程。) “why”的答案则需要逻辑推理或因果解释,常包含“because”等连接词。例如: 问:“Why do leaves change color in autumn?”(...
Why are C4 plants able to continue photosynthesis even at low CO2 levels? Carbon Dioxide: Carbon dioxide is a molecule that most living creatures produce by breathing or releasing it into the atmosphere. It can also be created when carbon is burnt in the presence of oxygen, such a...
The reason is that the stomata also supply plants with fresh air for photosynthesis.If plants sealed their stomata, this life-sustaining process would come to a halt for lack of carbon dioxide.But if the stomata are thrown wide open, the plants risk death due to the loss of moisture ...
Plants (and other autotrophs) undergo photosynthesis, which is a process that allows them to convert light energy (from the sun) to chemical potential energy. Humans (and other heterotrophs) on the other hand must consume something that has chemical potential energy (like plants or other ...
As cotton water stress levels are elevated, more severe reductions in vegetative growth occur and the leaf stomata begin to close. Photosynthesis slows, ultimately leading to significant reductions in amount and type of carbohydrates produced by the plant. Particularly during the early and middle boll...
~~11. The earth's early atmosphere did not contain oxygen. This changed dramatically once the early cells underwentphotosynthesis. a. Explain how photosynthesis was able to occur in earth’s early atmosphere. (5 points) The photosynthesis was using carbon dioxide which was present in the earth’...
