1. We take a potted plant like croton whose leaves are partly green and partly white. The green part of the leaf has chlorophyll but the white part of the leaf does not have chlorophyll. 2. Place this plant in a completely dark place for about three days to destarch its leaves. 3. ...
解析 答案:Chlorophyll is a pigment found in the chloroplasts of plant cells that absorbs light energy and uses it to convert carbon dioxide and water into glucose and oxygen, which are the energy source and byproduct of photosynthesis, respectively....
In photosynthesis, the energy from sunlight is first ___ by chlorophyll. A. caught B. absorbed C. received D. got 相关知识点: 试题来源: 解析 B。解析:本题考查光合作用中关于能量吸收的英语表达。“absorb”有吸收(光、热等能量)的意思,在光合作用中叶绿素是吸收太阳光的能量,这是一个特定的科学...
A variegated leaf with green and yellow patches in used for an experiment to prove that chlorophyll is required for photosynthesis. Before the experiment the green portions (A), and the pale yellow portions (B), are observed. What will be the colour of 'A' just before and after the...
To this end, photosynthesis activity was induced using 50 μmol photons m−2 s−1 of red (λ > 630 nm) actinic light. Red light is absorbed well by chlorophylls, but it does not interfere with the acquisition parameters of mVenus or CFP channels (465–561 nm). This ...
This is how the trees “know” to begin getting ready for winter. During winter, there is not enough light or water for photosynthesis .The trees will rest, and live on the food they have stored during the summer. They begin to close their food-making factories. The green Chlorophyll ...
Sunlight is also needed to make chlorophyll. If plants are kept in the dark, they can’t make chlorophyll and will have yellow leaves! You can see this in our multicolouredcress caterpillar. What affects the rate of photosynthesis Four factors affect the rate ofphotosynthesis. The faster it ...
Potassium – Potassium is needed for photosynthesis, plant growth, longevity, protein production as well as for the transportation of water, nutrients, and sugar in the plant. Magnesium – Magnesium is a part of chlorophyll and thus is required for photosynthesis. It also helps activate certain en...
What does transpiration produce that photosynthesis requires? What gases do plants use in photosynthesis? What does chlorophyll look like in a plant cell? What plant cell structure is composed of cellulose and lignin? What kind of plant vascular tissue carries sugar?
True or False about "The light reaction of photosynthesis": Cartenoids and Chlorophylls transfer energy to chlorophyll a by fluorescence. Photosynthesis and growth are examples of exergonic processes. True False True/FaIse: The oxygen you breathe comes...
