Round, rod shaped, or complex.

Goes inside of a cell called a host, shuts down its functions, and reproduces itself.

contractile vacuole which collects and expels water from the cell

It also has cilia which moves the cell, food vacuoles, and the cells reproduce asexually.

they move in different ways. some have flagella, cilia, or they depend on hosts for transport.

Green, unicellular algae in fresh water that produce food using the sun's energy. However, when sunlight is not available, it will act as a heterotroph and get food from its environment.

unicellular algae that light up in the water when disturbed at night by a passing boat or a swimmer.

unicellular protists with glasslike cell walls that float near the surface of lakes or oceans or they attach to rocks in shallow water. Some move my oozing chemicals out of slits in their cell walls and glide in the slime.

Red, multicellular seaweeds that absorb the small amount of light with their red pigments. Substances extracted from red algae are used in many products. Red algae itself is also eaten.

Brown seaweed that has many plant-like structures. Brown algae is eaten and substances extracted from it are also commonly used.

brilliantly colored slime molds live in moist, shady places and feed on bacteria and other microorganisms. The cells use pseudopods to feed and creep around. if food is scarce, the cells grow bigger or join together to form a giant, jellylike mass.

Water molds and downy mildews live in water or moist places. They look like fuzz and attack many food crops.

In 1845 and 1846, a water mold impacted history when it destroyed the Irish potato crops. The loss of the crops led to a famine, and more than 1 million people in Ireland died.

Ranges in size, all cells surrounded by cell walls and most fungi cells are arranged in structures called hyphae, which are the branching, threadlike tubes that make up the bodies of multicellular fungi. the hyphae are continuous threads of cytoplasm that contain many nuclei.

Fungi are heterotrophs but they absorb food through hyphae that grow into the food source. The digestive chemicals ooze from the hyphae into the food, which breaks down the food into small substances that the hyphae absorb.

Most fungi reproduce both asexually and sexually. Fungi reproduce by making spores, which are surrounded by a protective covering. Fungi produce millions of spores, and only a few will land in suitable living conditions. The spores are produced in fruiting bodies. In some fungi, the visible part of the fungus is the fruiting body. in other fungi, the fruiting bodies are the hyphae that grow upward.

three major groups of fungi are the club, sac, and zygote fungi, which are classified by the appearance of their reproductive structures.
