Students of Class XI (16鈥 17 years old) were asked to hypothesise on the role of different pigments found in plants with non-green leaves. The majority hypothesised that these plants were devoid of chlorophylls and some other pigments performed the function of photosynthesis. Their ideas were ...

The leaf also releases water vapor through its stomata in a process called transpiration. This process can be wasteful and to the plant’s detriment in the desert. For instance, some plants in the desert, like a large cottonwood tree, may lose water supply as much as 100 gallons per hour ...
Significance of Photosynthate Produced at Different Stages of Growth as Carbon Source for Fruit Filling and Seed Reserve Accumulation in Lupinus angustifol... Growth and reproductive phenology of field grown nonirrigated L. angustifolius cv. Unicrop were studied by periodic sampling of plants. Anthesis...
One of the main aims of current research in physiological ecology is to investigate and causally interpret the photosynthetic productivity of plants and of plant communities in different habitats. Efforts have been made to develop mathematical models to compute the net fixation of CO 2 by plants fro...

The plant enzyme Rubisco is the main enzyme converting atmospheric carbon dioxide into biological compounds, however, this enzymatic process is inefficient in vascular plants; this study demonstrates that tobacco plants can be engineered to fix carbon with a faster cyanobacterial Rubisco, thus potentially...
This chapter discusses the effects of a range of different parasitic plants on photosynthesis in their hosts and examines the mechanisms responsible for the changes observed. 展开 关键词: parasitic plants pathogen infection photosynthesis plant–attacker interaction root-knot nematodes (RKN ...
Photosynthesis in different types of transgenic tobacco plants with elevated cytokinin content Photosynthetic parameters were compared in three types of transgenic tobacco plants: ipt-transgenic plants with slightly elevated endogenous cytokinin (CK)... - 《Biologia Plantarum》 被引量: 0发表: 1997年 Phot...
