Plants are responsible for incredible feats of molecular transformation. Plant processes, such as photosynthesis, photophosphorylation, chemiosmosis, carbon fixing reactions, respiration, are presented in this tutorial...
Myelin sheath is essential for a faster conductivity of signals. Know more about this feature of some neurons in the Central Nervous System here. ..
Leaves are the major photosynthetic organ of a plant. Apart from that, they are also crucial to water movement. In this tutorial, various plant processes are considered in more detail. It also includes topics on leaf arrangements, leaf types, leaf structure, leaf color, abscission, and importance to humans...
Neurons generate electric signals that they pass along to the other neurons or target tissues. In this tutorial, you will find the basic structure of a neuron, the different classes of neurons, and membrane potentials. It also includes the structure of the nervous system...
