What is a Eukaryote?
A Eukaryote is a classification of cells that have both a nucleus and organelles. The unicellular organism is identified by its membrane-bound nucleus. The organelles that make up the inside of the cell are also membrane-bound.

Structures such as mitochondrion, intracellular filaments, and Golgi bodies perform the various tasks that they cell must maintain to sustain it. Eukaryotic cells are found in animal life, fungi, and plants. They can be found as single cells or in multicellular organisms.

The origin of the Eukaryote cell has been up for debate ever since discovery was made of the cells. There is no way to know for certain how the cells came into being. Their evolution is considered to be a milestone in the evolution of life. These organisms have been found in fossils. Studying these specimens suggest they have been identified as far back as 1650 million years.

What is known is how the cells function within the organisms they make up. The cells are known for being able to specialize cell functions. They can assume a variety of functions depending on the needs of the organism. Sometimes they might transmit nerve impulses, while in another part of the organism they may absorb nutrients. Groups of cells perform different functions within the same organisms.

The cells are small, measuring between ten and thirty micrometers width in animal cells. The cells divide via mitosis. The tiny cells also experiences sexual reproduction through meiosis. These building blocks of life are essential to survival. Scientist can learn a lot about the cycles of life by studying organisms such as Eukaryotes.

Most people are first exposed to Eukaryotes in high school biology. Lesson plans include learning the basics of how the cells work and the various parts of the cell. Learning this process at such a young age can be confusing. It is a difficult concept to comprehend.
