Eukaryotes

A collection of flashcards covering key concepts in the study of eukaryotic cells, their structures, functions, and interactions.

Eukaryotes

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

Morphology

The study of the form and structure of organisms.

Organelle

Specialized structures within a cell that perform distinct processes.

Nucleus

The organelle that contains most of the cell's DNA and is the site of transcription.

Mitochondrion

An organelle responsible for energy production through cellular respiration.

Chloroplast

An organelle found in plants that conducts photosynthesis.

Endoplasmic Reticulum (ER)

An organelle involved in the translation of proteins and lipid synthesis.

Golgi Apparatus

An organelle that modifies, sorts, and transports proteins.

Cytoskeleton

A network of fibers crucial for cell shape, support, and movement.

Meiosis

A type of cell division that reduces chromosome number by half to form haploid cells.

Chitin

A component of the cell walls of fungi, providing structure and rigidity.

Cellulose

A polysaccharide that forms the structural component of the primary cell wall in green plants.

Haploid

A cell containing one set of chromosomes (N).

Diploid

A cell containing two sets of chromosomes (2N).

Flagella

Long, whip-like structures used by cells for movement.

Pseudopodia

Temporary projections of eukaryotic cells used for movement and feeding.

Endosymbiotic Theory

The theory that eukaryotic cells evolved from symbiotic relationships between primitive prokaryotes.

Homeostasis

The ability of an organism to maintain a stable internal environment.

Vacuole

An organelle that is involved in storage and maintaining cell structure.

Lysosome

An organelle that contains digestive enzymes for breaking down waste materials.

Peroxisome

A small organelle that contains enzymes for oxidative reactions.

Gene expression

The process by which information from a gene is used to synthesize a functional gene product.

Cilia

Short, hair-like structures that help in cell movement and sensing the environment.

Fungi

A kingdom of eukaryotic organisms that includes yeasts, molds, and mushrooms; characterized by heterotrophic nutrition and chitin cell walls.

Fungi Phylogeny

The evolutionary history and relationships among different groups of fungi, often based on molecular and morphological data.

Chytridiomycota

A phylum of fungi, mostly aquatic, known for producing flagellated zoospores.

Zygomycota

A phylum of fungi characterized by the formation of a zygospore during sexual reproduction (e.g., bread molds).

Glomeromycota

A phylum of fungi that form arbuscular mycorrhizae, a symbiotic relationship with plant roots.

Ascomycota

A phylum of fungi commonly known as sac fungi, characterized by the production of ascospores in a sac-like structure called an ascus.

Basidiomycota

A phylum of fungi commonly known as club fungi, characterized by the production of basidiospores on a club-shaped structure called a basidium (e.g., mushrooms).

Protozoa

A diverse group of single-celled eukaryotic organisms that are heterotrophic and motile, often considered animal-like protists.

Giardia lamblia

A species of flagellated protozoan parasite that causes giardiasis, an intestinal infection in humans and other animals.

Slime molds

Eukaryotic organisms that can live freely as single cells but can aggregate to form a multicellular reproductive structure, resembling fungi.
