Question

define only spore formation in asexual reproduction in plants

Answer 1

Spore formation is a type of asexual reproduction in which one of the cell enlarge in size and its nucleus starts dividing to give rise to a number of nucleus present inside one cell. After that each nucleus get surrounded by the cytoplasm and separate from each other to form many cells called spores.

Bursting of the membrane leads to the dispersal of spores and each spore than develop into a new plant.
