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 the reproductive structure of the 'lower plants,' plants that don't flower. Fungi, algae, and even some bacteria all form spores when they want to pass their genes on.lant spores are produced by the organisms we can usually recognize. The major types of plants that form spores are algae, mosses, and ferns. Algae are the simplest of these plants, and can range from tiny, single celled things to large, multi-celled plants that cover your backyard pond.
