Topics include the team's investigation of stromatolites, which are structures created by sediment-trapping cyanobacteria, in Australia's Shark bay and how the discovery of chlorophyll f may help manufactur...
What is the opposite of a turgid plant cell? What color is a plant cell? What cells does the vascular cambium produce? Do any tropisms affect only one plant organ? What organelle within a plant cell contains chlorophyll? What does transpiration produce that photosynthesis requires?
A cell is the structural and fundamental unit of life. The study of cells from its basic structure to the functions of every cell organelle is called Cell Biology. Robert Hooke was the first Biologist who discovered cells. All organisms are made up of cells. They may be made up of a sin...

These substances are the result of secondary plant metabolism and are distinguished by the presence of several phenolic groups connected to complicated structures. Unlike the basic metabolites (chlorophyll, amino acids, and simple carbohydrates), which mediate in the processes of absorption, respiration,...
In mammalian cells, ACs activity is sensitive to physiological relevant fluctuations in the CO2/HCO3−/pH, Ca2+and ATP, especially in its substrate ATP. Thus, ACs functions as an environmental sensor and an integrator of intracellular signals (HCO3−, ATP or Ca2+) while tmACs respond to ...
Photosynthesis occurs in chloroplasts, a type of plastid (an organelle with a membrane) that contains chlorophyll and is primarily found in plant leaves. Chloroplasts are similar tomitochondria, the energy powerhouses of cells, in that they have their own genome, or collection of genes, contained...
Levels of total chlorophyll (chlorophyllsaandb) per cell decreased in WT but increased in thehxk1mutants with glucose (Fig.2a, b). However, because the cells grew larger with glucose (Fig.1h), the abundance of chlorophyll per cell volume decreased in both WT and the mutants (Fig.2b). ...
the greatest development of protoplast isolation occurred in 1960 when the first enzymatic method for the cell wall removal has been introduced by Cocking. Up to this time, protoplasts have been used extensively in transcriptional studies including vascular tissue. As vascular tissue cells are underrep...
