How plantlike protist are classified into different groups?

Answer 1

diatoms are one celled protists that float near the top of lakes and oceans and usually attack to rocks and are a main food source for heterotrophs.

dinoflagellates are also 1 celled organisms that look like there sorrounded by armor and have a variety amount of pigment and they have the ability to move with flagella even though they are plants.

eugleniods are quite special because they can photosynthesize and they can eat other protists. they look more animal like protists than plantlike but its mainly based off of photosynthesis, has a flagellam, and an eye

red algaes are multi cellular and due to their red pigment they survive in much deeper water than other protists.

green algaes are most one celled creatures but they sometimes group together and a few are multi cellular and a tiny few can live on land growing on rocks, moist soils, and cracks in trees. they share almost the same type of chloryphyl as trees

brown algaes should be familiar since they are generally seaweed with air sacs to keep them upright and a holdfast. they can form underwater forests and can have multiple pigments. brown algae are generally found in cool rocky waters.
