Eukaryotic cell
Réalisation personnelle (2023)
A eukaryotic cell is a complex cell that contains membrane-bound organelles, including a nucleus that houses the cell's DNA. These cells are typically larger and more structurally organized compared to prokaryotic cells. Eukaryotic cells are found in plants, animals, fungi, and protists.
The cell membrane surrounds the cell and controls the movement of substances in and out of the cell. Within the cell, various organelles perform specific functions. The nucleus contains the cell's genetic material and is responsible for controlling cellular activities. The endoplasmic reticulum is involved in protein synthesis and lipid metabolism. The Golgi apparatus modifies, sorts, and packages proteins for transport. Mitochondria generate energy for the cell through cellular respiration. Lysosomes contain enzymes for intracellular digestion and waste removal. The cytoskeleton provides structural support and facilitates cell movement. Lastly, the cell may also have specialized structures like chloroplasts in plant cells for photosynthesis or cilia and flagella for movement.
Eukaryotic cells are highly adaptable and can perform a wide range of functions depending on their specialized structures and organelles. This complexity allows eukaryotic organisms to carry out various biological processes necessary for their survival and reproduction.
