Features of xerophytes

Xerophyte survival characteristics:

Thick cuticle.

Stomatal closure.

Reduction in # of stomata.

Stomata hidden in crypts or depressions in leaf surface (less exposure to wind and sun).

Reduction in size of transpiration surface (lower leaf only).

Increased water storage.

Explanation:

Xerophyte adaptations increase water intake, limit water loss, and store water efficiently. Water intake adaptations include deep or widespread roots, and high salt content to increase osmosis. Xerophytes have thick cuticles, lost or finely divided leaves, reduced stomata, and CAM photosynthesis

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

the monocytes or macrophages of agranulocytes , dendritic cells which are accessory leucocytes, and b cells which is one type of lymphocytes   identify the antigens present on the pathogen's surface. these three cells are called antigen presenting cells(apc) which are phagocytes and destroy the antigens by secreting antitoxins. besides this leukocyte is always plays vital role in the immunity of the body.
