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 - Reproductive Cells. Spores are reproductive cells in plants, fungi, algae, and protozoa. They are typically single-celled and have the ability to develop into a new organism. Unlike gametes in sexual reproduction, spores do not need to fuse in order for reproduction to take place. Organisms use spores as a means of asexual reproduction. Spores are also formed in bacteria, however, bacterial spores are not typically involved in reproduction.
