Sejték

Sejték is a term that translates to "cells" in English. In biology, cells are the fundamental structural and functional units of all known living organisms. They are the smallest basic form of life. Organisms can be classified as unicellular, consisting of only one cell, or multicellular, composed of multiple cells that may be specialized for different functions.

The study of cells is called cell biology. Cells exhibit a remarkable diversity in size, shape, and function, yet they share common fundamental components and processes. A typical eukaryotic cell, found in plants, animals, fungi, and protists, contains a membrane-bound nucleus that houses the genetic material, and various organelles like mitochondria for energy production and ribosomes for protein synthesis. Prokaryotic cells, which include bacteria and archaea, are simpler and lack a nucleus; their genetic material is located in a region called the nucleoid.

Cellular processes such as metabolism, growth, reproduction, and response to stimuli are essential for life. Cells divide to create new cells, a process critical for organismal development, repair, and reproduction. The intricate organization and cooperative interactions of cells allow for the complex functioning of multicellular organisms. Understanding cells is paramount to comprehending life at its most basic level and is crucial for advancements in medicine, agriculture, and biotechnology.
