eukariótában

Eukariótában refers to a domain of life. Organisms within this domain are called eukaryotes. Key characteristics of eukaryotes include the presence of a membrane-bound nucleus that houses their genetic material, DNA. Unlike prokaryotes, which lack a nucleus, eukaryotic cells are more complex and compartmentalized.

Within the eukaryotic cell, various organelles, each with specialized functions, are enclosed by membranes. Prominent examples include mitochondria, responsible for energy production, and the endoplasmic reticulum, involved in protein and lipid synthesis. Eukaryotes also possess a cytoskeleton, providing structural support and facilitating movement.

The domain Eukarióta encompasses a vast diversity of life, including animals, plants, fungi, and protists. These organisms range from single-celled entities to multicellular beings with highly specialized tissues and organs. Reproduction in eukaryotes can be either sexual or asexual, often involving mitosis and meiosis. The evolutionary history of eukaryotes is a significant area of study, with evidence suggesting their origins involved endosymbiosis, where one cell engulfed another, leading to the development of organelles like mitochondria and chloroplasts.
