Produced by the sporophyte (i.e., spore-bearing) generation, plant spores give rise to the haploid gametophyte (i.e., gamete-bearing) generation. Transport proteins are proteins that transport substances across biological membranes. Transport proteins are found within the membrane itself, where they form a channel, or a carrying mechanism, to allow their substrate to pass from one side to the other.. A complete shutoff from the surroundings however is not useful: there has to be some exchange of materials to enable metabolism. The substances transported by these proteins can include ions such as sodium and potassium; sugars … Aquaporins, also called water channels, are channel proteins from a larger family of major intrinsic proteins that form pores in the membrane of biological cells, mainly facilitating transport of water between cells. These pores are collectively called stomata; a single pore is called Stoma. sweat pore: the surface opening of the duct of a sweat gland. Biology: What is what?
