    The plasma membrane or cell membrane is described as a selectively permeable membrane because it does not allow all kinds of substances to go through it. Only water can pass in and out freely of the cell in a process called osmosis. This is the reason why potatoes look soggy when it is soaked in water. The cells of potato take in more water in an attempt to balance the concentration of solute and solvent in and out of the cell.

    Materials like ions have to pass through certain complexes called gates. These gates are known for controlling the concentration of solute (ions) in and out of the cell in a process called diffusion. This is evident in the movement of ions in the transmission of electrochemical signals in the nervous system or the pumping of potassium and sodium in action potentials in muscles.

    When you visit a website, you are of course observable by the site itself, but you are also observable by third-party trackers that the site embeds in its code. You might be surprised to learn that the vast majority of websites include many of these third-party trackers. Websites include them for a variety of reasons, like for advertising, analytics, and social media.

    The Leucanthemum vulgare daisy is a very common plant that belongs to the Asteraceae (composite) family.

    The vase plants now on sale form low, compact shrubs from which arise flower stems that bear the typical flower heads. Daisies are generally hardy species that adapt well in full sun and in part-shade.
