Once in the mesophyll cells, CO 2 diffuses into the stroma of the chloroplast, the site of light-independent reactions of photosynthesis. These reactions actually have several names associated with them. Other names for light-independent reactions include the Calvin cycle, the Calvin-Benson cycle, and dark reactions.
What is Vellus Hair. Vellus hairs are a type of human hair that are fine, short, light-colored or transluscent, and non-pigmented that develop from childhood and are found on most areas of the body. Their growth is not, in contrast to terminal hairs, affected or dictated by hormones.
A root hair is a tubular outgrowth of root epidermal cells of vascular plants. They are found only in the region of maturation of the root. Root hairs are a specialized form of rhizoid. Root hairs form an important surface over which plants absorb most of their water and nutrients.
