Eukaryotic

Eukaryotic refers to any organism whose cells contain a nucleus and other organelles enclosed within membranes. Eukaryotes are one of the three recognized domains of cellular life, the other two being Prokaryotes and Archaea.

Characteristics

Eukaryotic cells are larger than prokaryotic cells and have a "true" nucleus, membrane-bound organelles, and rod-shaped chromosomes. The nucleus houses the cell's DNA and directs the synthesis of proteins and ribosomes.

Classification

Eukaryotes can be classified into four major groups: Animals, Plants, Fungi, and Protists. Each group has distinct characteristics and evolutionary histories.

Evolution

The origin of the eukaryotic cell is a milestone in the evolution of life, as it allowed the development of complex multicellular organisms. The most widely accepted hypothesis is that eukaryotic cells evolved from a symbiotic association of prokaryotes.

Reproduction

Eukaryotes can reproduce both sexually and asexually. The process of sexual reproduction in eukaryotes involves meiosis, gamete formation, and fertilization.
