Alternation of generations

A reproductive strategy that involves a succession of haploid and diploid phases.

Type of motion in which cytoplas can flow beneath the cell membrane into new branches called pseudopods, helped by filaments of a structural protein called actin, causing the cell to move in a given direction.

Short hair-like projections found on eukaryotic cells that can help the cell move or can sweep food particles toward the mouth.

The pigment found in green plants and algae that allows them to undergo photosynthesis

The organelles in which photosynthesis takes place in green plants and algae.

This theory states that eukaryote organelles may have evolved when large eukaryotic organisms engulfed but did not digest smaller organisms and a symbiotic relationship arose.

An organism that has only one type of gamete rather than separate male and female gametes.

In ciliates, the large nucleus that holds many copies of the cells genetic material. It is responsible for the growth and metabolism of the cell.

In ciliates, the smaller nucleus responsible for the transmission of genetic material during sexual reproduction.

In ciliates, the membrane structure that functions in food uptake.

Method of food uptake in which a liquid or small food particle is sucked into an invagination in the cell membrane, which then folds in on itself and pinches off from the cell membrane to become a small vacuole.

Method of food uptake in which a flexible portion of the cell membrane surrounds a food particle and engulfs it, bringing it into the cell in a vacuole. Phagocytosis is used to ingest other unicellular organisms or large particles.

The process in which some organisms can use the energy of light to transform inorganic materials into usable organic materials.

Small free-floating organisms in fresh- and saltwater that are a major marine food source.

The diploid vegatative phase of acellular slime molds

The haploid slug-like phase of cellular slime molds that gives rise to the fruiting body

Temporary cytoplasmic protrusions of ameboid cells that function in movement and food uptake by phagocytosis.

The light sensative region in euglenoids that allows them to move toward light sources.

A membrane bound portion of the cell usually used for holding materials such as food and waste.
