Plankton. Plankton includes plants and animals that float along at the mercy of the sea's tides and currents. Their name comes from the Greek meaning drifter or wanderer.. There are two types of plankton: tiny plants--called phytoplankton, and weak-swimming animals--called zooplankton.Some are babies that will grow into strong-swimming, non-planktonic adults. Others will remain plankton for their entire lives.here are two types of plankton: tiny plants--called phytoplankton, and weak-swimming animals--called zooplankton.

BACKGROUND: Non-vascular plants do not have transport tubes to carry water and food throughout the plant. Types of non-vascular plants include algae, fungi, mushrooms, yeasts, lichens, mosses, liverworts and molds. Bread mold looks like tiny fluffs of cotton. These structures are called hyphae. Some hyphae resemble roots. Hyphae release enzymes that break down chemicals in bread. The broken-down chemicals provide food for the mold. Tiny black spheres on bread mold are spore cases, which provide spores for reproduction. These organisms can be observed under a hand lens. Because non-vascular plants have no way to transport water and food over long distances, they must live near a source of water and food. Non-vascular plants are often called simple plants because they lack true stems, roots and leaves.
