A space in rock, soil, or unconsolidated sediment that is not occupied by mineral matter and that allows the passage or absorption of fluids: Water seeped into the pores of the rock. Among plants—all of which have a life cycle characterized by alternating generations of asexually and sexually reproducing individuals—spores are the reproductive agents of the asexual generation. In humans, it is the body’s largest organ, covering a total area of about 20 square feet. Definition, Structure, and Function. While these pores tend to be secretory, not all function in this way. Cristae are sub-compartments of the inner membrane of mitochondria and are essential to mitochondrial function. UHH > Faculty of Biology > Teaching Stuff > Highlights of Biochemistry > Pores - Channels - Transport: suchen : alpha-hemolysin from Staphylococcus aureus: The cytoplasm of living cells is separated from the environment by means of membranes. 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. 2.
