What must happen to the fern egg before spores are produced?
The fern egg, also known as the spore-producing structure called a sporangium, must undergo meiosis to produce spores. Meiosis is a type of cell division that results in the formation of spores with half the number of chromosomes as the parent cell.
Must spores occur in mitosis?
Spores are produced through a specialized form of cell division called meiosis, not mitosis. Meiosis involves two rounds of cell division that results in the formation of haploid spores with half the number of chromosomes as the parent cell. These spores will eventually undergo mitosis to form new multicellular organisms.
How do ferns reproduce without seeds?
Ferns reproduce through spores instead of seeds. Spores are produced in structures called sporangia on the underside of fern fronds. When mature, the sporangia release spores which, when dispersed by the wind, water, or animals, can germinate into new fern plants.
