Why are most cells so small? Why is homeostasis important for cells? Why does cell signaling exist in single-celled organisms? Why are animal cells more irregularly shaped than plant cells? Why do some cells have microvilli? Why do neurons die without oxygen?
How do plant cells elongate?Answer and Explanation: Plant cells are surrounded by a tough but flexible layer of cellulose and other molecules called the cell wall. The cell wall helps to counteract osmotic pressure created by diffusion of water across the plant's cell membrane; it also, ...
A class of plant hormones (especially INDOLE-3-ACETIC ACID (IAA) and similar compounds) that control cell division, cell expansion and differentiation. Cambium A population of stem cells that sustain the production of vascular tissues in higher plants. They allow the stem and the root to increas...
For example, “What do chloroplasts enable plant cells to do?” can be simply answered as “photosynthesis,” whereas behavior-2 questions were defined such that their answers always required inference. Fig. 4 Mean of depth for each type of annotations Full size image The analysis was repeated...
This coincides well with the fact that Chk-1 inhibition sensitizes colon carcinoma HCT116 cells to lidamycin through abrogation of a G2/M checkpoint and induction of a caspase-2-dependent apoptotic pathway. In addition, a distinct mechanism of caspase-2 inhibition during mitosis has been ...

It is worth mentioning that low pH itself induces oxidative stress in plant cells and hence, through the production of ROS, it may also lead to DNA damage [67]. So, plants are continuously exposed to conditions harmful to their DNA. It has to be noted that DNA damage can also be ...
Spherulites® is an equine cleansing product that consists of 1 µm microparticles of plant-derived surfactants. This product contains chitosan and chitosanide which assist in forming a tightly bound film coating over the equine hair and skin. The tightly bound film increases the contact time ...
