What is an example of an organelle?
What is an example of an organelle?
The nucleus, the mitochondrion, the chloroplast, the Golgi apparatus, the lysosome, and the endoplasmic reticulum are all examples of organelles. Some organelles, such as mitochondria and chloroplasts, have their own genome (genetic material) separate from that found in the nucleus of the cell.
What are organelles definition for kids?
In cell biology, an organelle is a part of a cell that does a specific job. Organelles typically have their own plasma membrane round them. Most of the cell’s organelles are in the cytoplasm. The name organelle comes from the idea that these structures are to cells what an organ is to the body.
What is an organelle short answer?
An organelle is a tiny cellular structure that performs specific functions within a cell. Organelles are embedded within the cytoplasm of eukaryotic and prokaryotic cells. In the more complex eukaryotic cells, organelles are often enclosed by their own membrane.
What do you mean by organelles?
In cell biology, an organelle is a specialized subunit, usually within a cell, that has a specific function. The name organelle comes from the idea that these structures are parts of cells, as organs are to the body, hence organelle, the suffix -elle being a diminutive.
What are the types of organelle?
6 Cell Organelles
- Nucleus. nucleus; animal cell.
- Ribosomes. Ribosomes are the protein factories of the cell.
- Endoplasmic reticulum. Ribosomes on the outer surface of the endoplasmic reticulum play an important role in protein synthesis within cells.
- Golgi apparatus. Golgi apparatus.
- Chloroplasts. chloroplast structure.
- Mitochondria.
What organelle is DNA located in the cell?
nucleus
What organelle have its own DNA?
mitochondria
Which organelle is responsible for Apoptosis?
What is not considered an organelle?
Nucleolus. Within the nucleus is a small subspace known as the nucleolus. It is not bound by a membrane, so it is not an organelle. This space forms near the part of DNA with instructions for making ribosomes, the molecules responsible for making proteins.
Is a membrane an organelle?
The plasma membrane is the organelle that encapsulates the contents of the cell. Apart from encapsulating cell contents, the plasma membrane also plays a vital role in regulating the movement of substances in and out of the cell. The plasma membrane is made up of two layers of phospholipids (phospholipids bilayer).
What is the importance of an organelle?
An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body. Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins.
