Which photosynthesis process can occur at night

The Calvin cycle

chemical reactions that take place in chloroplasts during photosynthesis

Some plants such as cacti can prepare materials for photosynthesis during the night by a temporary carbon fixation and storage process. This is due to having the ability to open the stomata at this time, and conserve water due to cooler temperatures at night in order to tolerate the heat in the day.

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.
