Chlorophyll is an essential pigment moleculefor photosynthesis, the chemical process plants use to absorb and use energy from light. It's also used as a food coloring (E140) and as a deodorizing agent. As a food coloring, chlorophyll is used to add a green color to pasta, the spirit absin...
PhotosynthesisTHE use of tritiated water affords a sensitive means of answering at least one question about early photosynthetic events : Do any of the hydrogen atoms of the chlorophyll molecule intervene in the electron transport chain between water and oxidant ? It has already been established 1 ...
The only difference is that bears lie down in a cave to sleep, and trees lose all their leaves and stand up to sleep.What is photosynthesis? A.Trees use sunlight and glucose to make chlorophyll.B.Trees use sunlight and chlorophyll to make glucose.C.Bears lie down in a cave to sleep.D...
根据第一段的第一句 "Photosynthesis(光合作用)appears when a tree uses the sunlight and chlorophyll (叶绿素)to make glucose" 可知,当树使用阳光和叶绿素合成使葡萄糖时光合作用就会出现,故正确答案为B。 (2) 细节理解题。根据第一段的最后一句 "It is not the glucose but chlorophyll that turns the ...
The meaning of CHLOROPHYLL is the green photosynthetic pigment found chiefly in the chloroplasts of plants and occurring especially as a blue-black ester C55H72MgN4O5 or a dark green ester C55H70MgN4O6 —called also respectively chlorophyll a, chlorophyl
Measuring the photosynthetic rate of tall fescue (Festuca arundinacea) at low temperatures is difficult because dew or frost on the leaves often prevents the use of a CO2 analyzer. Chlorophyll fluorescence measurements may make it possible to estimate photosynthetic potential when it is impossible to ...

Chlorophyl b is also involved in photosynthesis and absorbs primarily blue light. There are other forms of chlorophyl such as Chlorophyll c1, c2, c3 which are accessory pigments. Recently, Chlorophyll f was announced to be present in cyanobacteria and other oxygenic microorganisms that form ...
