Eukaryotic cells are a type of cell that make up all organisms within the domain Eukarya, which includes plants, animals, fungi, and protists. These cells are characterized by having a true nucleus, which is a membrane-bound organelle that houses the cell's genetic material, DNA. The presence of a nucleus separates the genetic material from the rest of the cell, allowing for more complex and specialized functions.
Eukaryotic cells are typically larger and more complex than prokaryotic cells, which are cells that lack a nucleus. They contain numerous membrane-bound organelles, such as mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, and chloroplasts (in plants). These organelles compartmentalize different cellular processes, allowing for more efficient and specialized functions.
One of the defining characteristics of eukaryotic cells is their ability to perform complex cellular processes such as mitosis and meiosis, which are involved in cell proliferation and reproduction. These cells also have a cytoskeleton, which provides structural support and enables cell movement and shape changes. Additionally, eukaryotic cells are capable of performing various forms of endocytosis and exocytosis for nutrient uptake and waste removal.
Eukaryotic cells have a plasma membrane that surrounds the cell, separating its internal components from the extracellular environment. This membrane is selectively permeable, allowing for the regulation of the passage of molecules in and out of the cell.
Overall, eukaryotic cells exhibit a high degree of complexity and specialization, allowing them to perform a wide range of functions essential for the survival and growth of organisms.

What is the difference between prokaryotic cells and Eukaryotic cells
The main difference between prokaryotic and eukaryotic cells lies in their internal structure and complexity.
1. Nucleus: Prokaryotic cells lack a true nucleus, whereas eukaryotic cells have a membrane-bound nucleus that contains their genetic material (DNA).
2. Organelles: Most organelles are absent in prokaryotic cells, while eukaryotic cells contain numerous membrane-bound organelles such as mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, and chloroplasts (in plants). These organelles allow for compartmentalization and specialized cellular functions.
3. Size: Prokaryotic cells are generally smaller and simpler than eukaryotic cells, which are typically larger and more complex.
4. Cell division: Prokaryotic cells undergo a form of cell division called binary fission, where the cell replicates its DNA and divides into two daughter cells. Eukaryotic cells undergo more complex forms of division, such as mitosis for growth and asexual reproduction, and meiosis for sexual reproduction.
5. Reproduction: Prokaryotes primarily reproduce asexually through binary fission, without the need for specialized reproductive structures. Eukaryotes have various modes of reproduction, including both asexual and sexual reproduction, often involving specialized reproductive structures and processes.
6. Complexity: Eukaryotic cells exhibit a higher level of complexity due to their larger size, membrane-bound organelles, and ability to perform specialized cellular processes. Prokaryotic cells, on the other hand, are more simple in structure and function.
7. Examples: Prokaryotic cells are found in bacteria and archaea, whereas eukaryotic cells are found in plants, animals, fungi, and protists.
Overall, the main distinctions between prokaryotic and eukaryotic cells are the presence of a true nucleus, membrane-bound organelles, complexity, and modes of reproduction.

What are the main organism involved in prokaryotics cells
The main organisms involved in prokaryotic cells are bacteria and archaea. These microorganisms are classified under the domains Bacteria and Archaea, respectively. They are unicellular and lack a membrane-bound nucleus and organelles. Prokaryotic cells are found in a wide range of habitats, including soil, water, the human body, and extreme environments such as hot springs and deep-sea hydrothermal vents. Bacteria and archaea play crucial roles in various ecosystems, performing essential functions such as nutrient cycling, decomposition, and nitrogen fixation. They also have both beneficial and harmful interactions with other organisms, including humans. Some bacteria and archaea can cause infections and diseases, while others offer benefits such as aiding digestion or producing antibiotics.
What are the main organism involved in Eukaryoyic cells
The main organisms involved in eukaryotic cells are plants, animals, fungi, and protists. These organisms exist within the domain Eukarya.
Plants: Eukaryotic cells make up various plant structures, including roots, stems, leaves, and flowers. Plants are multicellular organisms that use eukaryotic cells to carry out functions such as photosynthesis, nutrient uptake, reproduction, and growth.
Animals: Animal cells are eukaryotic and make up the tissues, organs, and organ systems of animals. These cells are involved in various functions such as digestion, respiration, movement, reproduction, and sensory perception.
Fungi: Fungi display eukaryotic cells and include organisms such as yeasts, molds, and mushrooms. Fungal cells are involved in various functions, including nutrient absorption, reproduction, and the decomposition of organic matter.
Protists: Protists are a diverse group of eukaryotic microorganisms that do not fit into the categories of plants, animals, or fungi. They include single-celled organisms such as amoebas, algae, and some parasites. Protist cells perform functions such as locomotion, photosynthesis, feeding, and reproduction.
Overall, eukaryotic cells are found in a wide range of organisms, including plants, animals, fungi, and protists. These cells contribute to various biological processes and functions necessary for the survival and growth of the organisms within these domains.
