Early land plants like mosses did not have vascular tissue. They must absorb their water directly from their surroundings, such as growing on rocks or trees that are moist. You find mosses in damp areas for this reason. They cannot grow in drier climates because they cannot pull water from the ground like vascular plants. Ferns are also suited to reproduce in more moist/humid climates because water must be present for their gametes (sperm and eggs) to find one another for fertilization. Seeds are adaptations by angiosperms and gymnosperms that allow for waterless fertilization. Either wind or animal pollinators help spread pollen and help the sperm reach egg cells for fertilization to occur. For that reason, these plants are better suited to survive in drier, modern climates.

Transport of a substance from the lumen (cavity) of an organ into one side of a cell and out the other side of the cell into the extracellular fluid is called <u>transcellular transport</u>.
The two routes of transport of substances across the epithelium of the gut are by transcellular method and paracellular method.
Transcellular transport refers to the transport of solutes across a epithelial cell layer through the cells. The best example is the movement of glucose from the intestinal lumen to the extracellular fluid by the epithelial cells. The epithelial cells use the active transport to generate the transcellular transport. Active transport refers to the transport of substances from a region of its lower concentration to a region of its higher concentration against the concentration gradient using cellular energy.
