The most diverse group of eukaryotes.

Includes some but not all organisms descended from a common ancestor.

A group of organisms descended from a common ancestor and includes all of its descendants.

Organisms with cells containing a nucleus and other membrane-bound organelles.

Large categories for classifying eukaryotes (like protists).

Groups that include a common ancestor and all of its descendants.

The study of evolutionary relationships amongst organisms.

Categorization and classification of protists.

Protists that make their own food through photosynthesis, like algae.

Protists that get food by consuming other organisms.

Protists that get energy through both photosynthesis and consuming other organisms.

A unicellular parasite found in rat blood, transmitted by fleas.

A supergroup of protists, including Trypanosoma.

Protists live in freshwater, saltwater, and as parasites.

Protists can reproduce both sexually and asexually.

A type of brown algae known for being the longest and fastest-growing algae. It is multicellular, large-bodied, mostly marine, and provides habitat for other organisms. Its color comes from the carotenoid pigment fucoxanthin.

Short, hair-like projections that cover the surface of some protists. They are used for movement and feeding. They are shorter and more numerous than flagella.

A large nucleus found in Paramecium. It controls everyday cellular functions.

A small nucleus found in Paramecium. It is involved in sexual reproduction through conjugation.

A sexual process in Paramecium that involves the exchange of genetic material between two individuals. It's not reproduction, but contributes to genetic variation.

The shells of Foraminiferans, made of calcium carbonate. They can be multi-chambered and arranged in a linear or spiral shape.

Foraminiferans are heterotrophic and parasitic, meaning they obtain nutrients by consuming other organisms.

The shells of Radiolaria are made of silica, fused into a single spherical piece.

Threadlike projections used for swimming, test formation, and feeding. They are used to capture food through phagocytosis.

Many Foraminiferans have a symbiotic relationship with algae, where both benefit. The forams get food from the algae, and the algae get protection and shelter.

A group of eukaryotic organisms often characterized by a feeding groove and unique flagella arrangement.

Excavata can be heterotrophic (consuming other organisms), autotrophic (making their own food), or parasitic (living off a host).

A diverse group of eukaryotic organisms, often photosynthetic, with a characteristic feature of having two flagella (one hairy, one smooth).

Unicellular algae with a hard, silica-based shell (test), generating a significant amount of Earth’s oxygen.

Diatoms thrive in both freshwater and saltwater environments, and are part of plankton.

Diatoms display two main body forms: centric (radial) and pennate (bilateral).

Diatoms have glass-like silica walls in an organic matrix (test) providing protection.

A single-celled, heterotrophic organism that lacks a shell and moves using pseudopodia (lobe-shaped extensions of its cytoplasm)

Lobe-shaped extensions of an amoeba's cytoplasm that are used for movement and engulfing food

A clade within the Archaeplastida supergroup, encompassing various green algae with characteristics similar to land plants, such as chlorophyll a & b, starch storage, and cellulose cell walls

A multicellular green algae with a leaf-like blade and root-like holdfasts, commonly found in intertidal zones

A filamentous green algae characterized by its distinctive spiral-shaped chloroplasts

Describing a long, thread-like structure, such as a filamentous algae like Spirogyra

A root-like structure that anchors an alga to a substrate

The body of a multicellular alga, often differentiated into leaf-like blades and root-like holdfasts
