Why do we have an appendix? They do not attract light, they absorb it, that is why they are darker. A. Plants need the larger amount of sun to photosynthesize so they will be more likely to do so in the summer were the sun is bright and available more than in the winter where its cloudy and gloomy. Many leaves even turn yellow or orange before death, resulting in beautiful fall foliage in various parts of the world. The red or purple color is caused by pigments called anthocyanins. There is a trend, however. The lower leaves receive less sunshine because they are shaded by the upper leaves. The End! There is a trend, however. As the leaves mature, they become darker green. Why do mature leaves photosynthesize faster than young leaves? Will this affect my investigations into photosynthesis? So since they have chlorophyll, they can carry out photosynthesis. At low light levels, green leaves are most efficient at photosynthesis. It is true to say that a leaf will continue to photosynthesise even after it has been removed from the plant, but not for ever. Like wearing black jeans and a white top. I did an experiment in my bio class and can't come up with a logical explanation, could someone help me? On a sunny day, however, there is essentially no difference between red and green leaves’ ability to trap the sun’s energy. Redesign Conclusion Pictures If our group was to improve upon our experiment we would: Exclude the solution without CO2 ; In the previous lab, we discovered that the leaves do not float unless there is CO2 in the These are leftovers from past evolutionary adaptations that are not necessarily being "eliminated" from the gene pool. So in order to get more light it is darker to absorbs the most of light that hits it. Why do we have a tail bone still? My tree has red leaves all year. Why do you think purple is not a very common plant color? Q. From my knowledge as an A-level Biology student, the cells on the underside of leaves do contain a limited amount of chloroplasts. Light colors reflect more light (to your eyes), that is why they are light. In most places, there is litttle sunlight during the winter. This is also why some plants have white stripes on it's leaves to … Why do darker colored leaves have a faster rate of photosynthesis? Thanks for asking, Answer 2: The leaves of purple plants still have chlorophyll which looks green to us. Why do we have a tail bone still? Why do you think purple is not a very common plant color? Photosynthesis in detached leaves Will a leaf photosynthesise if no longer attached to the plant and if so, how long for? In the summer, most always the sun is shining. Leave per se do not photosynthesize but the organelles within the cells of the leaves (the chloroplasts) do. How does a plant support itself without green chlorophyll? You might be interested in studying plant ecology or plant physiology. Some plants, including some Acer species, as well as Poinsettia species, have very colorful or dark non-green leaves. From my knowledge as an A-level Biology student, the cells on the underside of leaves do contain a limited amount of chloroplasts. Maybe a few hundred photosynthetic species have been measured for maximum photosynthetic rates, and I'd only consider a few dozen of those species to really be thoroughly examined. Maybe a few hundred photosynthetic species have been measured for maximum photosynthetic rates, and I'd only consider a few dozen of those species to really be thoroughly examined. Some parasitic plants lack chlorophyll entirely and …
