Protists can be unicellular, multicellular or colonial. Some move around and act like animals, others perform photosynthesis like plants, and still others seem to "think" they're fungi! You might not think a tiny one-celled amoeba has much in common with a giant sea kelp, but they're both members of the protist kingdoms. Protists: Many are single celled, some are multi-cellular. Many use photosynthesis, some hunt for food or absorb their food. Some are parasites..like the above giardia. This tiny protist can make you really sick. Biologists kind of group the Protists that are not bacteria, animals, plants and fungi, they are everything else. Specifically, this is their scientific classification: Characteristics: All protists are eukaryotic, and can be unicellular or multicellular. Habitat: Most protists live in water, some live in moist soil, and some in the human body . Food Sources: Protists can be heterotrophic or autotrophic . Reproduction: Protists reproduce asexually. These protists have tails (flagellum) and cilia to help them move. Amoeba have false feet that ooze forward or backward to help it move. Others are parasites and live in your body. FUNGUS-LIKE PROTISTS: Like fungi, they are heterotrophs, meaning they must obtain food outside themselves. They also have cell walls and reproduce by forming spores, just like fungi. Fungus-like protists usually do not move, but a few develop movement at some point in their lives. Two major types of fungus-like protists are slime molds and water molds. PLANT-LIKE PROTISTS: Plant-like protists are known as algae (Figure below). They are a large and diverse group. Plant-like protists are autotrophs. This means that they produce their own food. They perform photosynthesis to produce sugar by using carbon dioxide and water, and the energy from sunlight, just like plants. Unlike plants, however, plant-like protists do not have true stems, roots, or leaves. Can you guess which type of protist these are? That will be the tricky part when you look at your own water samples.

On the 8th picture it looks like the parasite is spinning.

Wow, and I thought I knew a thing or two about protists. I guess not.

The first picture looks like a hair pin even though it's a protist. 🤣

Mrs. TaylorI love science! Everything about the world is interesting and never boring. I love to study plants, animals, insects, and people. My favorite subjects are my students who are the most unique organisms on the planet! Categories |
