- Mutualism
- A relationship between two or more organisms of different species where all benefit from the association.
- Symbiosis
- A relationship between two or more species where at least one benefits.
- Phytoplankton
- Tiny floating photosynthetic organisms, primarily algae.
- Cilia
- Hair-like projections that extend from the plasma membrane and are used for locomotion
- Plankton
- Tiny organisms that float in the water.
- Spore
- A reproductive cell with a hard, protective coating.
- Eyespot
- A light-sensitive region in certain protozoa
- Vacuole
- A membrane-bound "sac" within a cell.
- Zooplankton
- Tiny floating organism that are either small animals or protozoa.
- Endoplasm

- Thallus
- The body of a plant-like organism that is not divided into leaves, roots, or stems.
