Things to Know!
If you would like to learn about the parts of the cell, watch videos, or learn cell theory, go to the link below:
New Definitions:
Autotrophic: To be able to make your own food. Anything that has chloroplast is an example of an autotrophic.
Anterior: The front or head.
Protist: A single celled organism that lives in water.
Asexual Reproduction: (Definition not provided)
Sexual Reproduction: (Definition not provided)
Binary Fission: A common way of asexual reproduction in protist. In Binary Fission, an organism literally splits it's DNA and organelles in half to create a replica of itself.
(Video Example Below)
New Organelles:
Contractile Vacuole: An organelle in found in almost all protist that controls the amount of water that leaves and stays in the organism. Protist live in water, so a defective contractile vacuole is very dangerous. A protist may dry explode if water cannot leave the cell.
Flagellum: A tail like strand that pulls a single celled organism through the water.
