Meristem culture involves culturing of differentiated cells; whereas callus culture involves culturing of undifferentiated cells.
A meristem consists of actively dividing cells. The cells formed by cell division gets differentiated into different types of cells which give rise to different tissues in the mature organ, developing from that meristem.
Meristem culture mainly involves culturing a bud in culture medium under aseptic conditions. The bud develops into shoot in the culture as the meristem already has the cells differentiated to give rise to different tissues of shoot.
Microspores are land plant spores that develop into male gametophytes, whereas megaspores develop into female gametophytes.[1] The male gametophyte gives rise to sperm cells, which are used for fertilization of an egg cell to form a zygote. Megaspores are structures that are part of the alternation of generations in many seedless vascular cryptogams, all gymnosperms and all angiosperms. Plants with heterosporous life cycles using microspores and megaspores arose independently in several plant groups during the Devonian period.[2] Microspores are haploid, and are produced from diploid microsporocytes by meiosis.[3]
