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.
Fundamentally, spores and gametes are very different. One difference is in the type of reproduction that each are involved in. Spores are used in asexual reproduction, while gametes are used in sexual reproduction.Another difference is in what each needs to develop into the next stage in the life cycle.A spore has the ability to grow into the adult gametophyte all by itself.he structure that produces a gamete is already haploid and so does not need to change the number of chromosomes it has in order to produce haploid gametes. So, hopefully this post explains how different spores and gametes are. I wanted to highlight this information because I see it as a common source of error.
