corona the outer atmosphere of the sun, temp. may reach 2,000,000 c

chromosphere middle layer of the sun's atmosphere

photosphere visible surface of the sun

convection zone layer of the sun which energy travels by convection from the radiative zone to the photosphere

radiative zone layer of the sun which energy is transferred away from the core by radiation

core very dense center of the sun

nuclear fusion process by which tow or more low-mass atomic nuclei fuse to form another, heavier nucleus.

radiation when energy is transferred as electromagnetic waves

convection the process in which heat is transferred by the circulation or movement of matter

differential rotation the way the sun rotates, rotating faster at its equator than at higher latitudes

sunspots dark areas that form on the surface of the sun

solar flare an explosive release of energy that can extend outward

prominences huge loops of cool gas that extend outward from the photosphere

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.

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.
