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[edit | edit source]
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[edit | edit source]
Eukaryotes can be classified into four major groups: Animals, Plants, Fungi, and Protists. Each group has distinct characteristics and evolutionary histories.
Evolution[edit | edit source]
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[edit | edit source]
Eukaryotes can reproduce both sexually and asexually. The process of sexual reproduction in eukaryotes involves meiosis, gamete formation, and fertilization.
