stayelectron microscopeEach particle is a pair of mutually perpendicularmicrotubuleThe cylindric body is 0.15~0.2 μ m in diameter, and its length varies with cell type, generally about 0.5 μ m.Centromere and grana are cellularMicrotubule Organization CenterIts function is related to that of dividing cellsSpindleAnd the formation of cilia and flagellar microtubules.
CentrioleGranaStructural similarityThe microtubule arrangement is 9+0 type.fromCross sectionLook, it is composed of nine groups of microtubules, each group also includes three microtubules of well array a, b and c, which is called triad.
thylakoidGeneral edgechloroplastThe long axis is arranged in parallel, on which there are pigments, which can absorb, transfer and transform light energy.In some parts, many round cake like thylakoids (ranging from two to more than 100) are stacked into stacks, called grana.The grana is the place for photosynthesis and light reaction.
