a long projection that looks much like a whip. as the flagellum whips back and forth, the organism is propelled through the water
Short, hairlike projections. This beats back and forth like oars to propel a cell through water.
Two organisms join together and exchange some of their genetic material. New individuals are not formed, but new combinatins of genetic material created
A tiny cell that can grow into an organism. They have complex life cycles that involve two or more diferent hosts.
Characteristics of six groups of plant-like protists
diatoms, dinoflagellates, euglenoids, red algae, brown algae, and green algae
Unicellular organisms found in both fresh water and salt water. Produce thin cell walss rich in slicon. Used in products such as toothpaste, filters, and scouring products
Half are autotrophs, the other heterotrophs. Have 2 flagella causing the protists to spin. Reproduce asexually through binary fission.
These protists are unicellular and live mainly in fresh water. Have chloroplasts needed for photosynthesis and no cell wall. Has a pigment known as the eyespot that helps them find sunlight for photosynthesis. Reproduce asexually through binary fission.
are multicellular. Less than 1 meter length. Live at great depths because they are very efficient at gathering light energy.
Found in cool climates. Multicellular. In cool, shallow ocean waters. Largest and most complex algae. Can grow up to 100 meters long.
Have photosynthetic pigments and cell walls that are the same as those in plants. Found in fresh and salt water and in some moist land area. Some are single cells, some live in colonies, few are multicellular. Reproduce through a cycle of alternation of generations.
