A point mutation is a change in a single base pair in DNA. A change in a single nitrogenous base can change the entire structure of a protein because a change in a single aminâ¦o acid can affect the shape of the protein. A frameshift mutation is a mutation in which a single base is added or deleted from DNA.
how are spores structurely different from seeds of plants. Spores are single cells with a haploid genome that have very little stored nutrients and water. They divide and grow to become a gametophyte. Spores are equivalent to pollen (the male, 2 celled gametophyte) rather than seeds.eeds are sporophytes. They are large & multicellular with a diploid genome formed from the merger of two gametes and endosperm formed from the merger of the central cell and a male sperm nuclei making it triploid. Seeds have a growth period before they go dormant for release.
Spores are specialised cells of the fungus that can function as resting or dispersal propagules. Each spore has the potential to generate another individual of the species. In contrast to seeds, spores have no specialised components that differentiate them from other cells of the thallus.he haploid sexual spores of the Ascomycota are formed inside an ascus. Spore formation is initiated following hormonal interaction between hyphae of different mating types. Following plasmogamy, the two haploid nuclei exist in a dikaryon for a short period.
