"In cell biology, the nucleus (pl. nuclei; from Latin nucleus or nuculeus, meaning kernel) is a membrane-enclosed organelle found in eukaryotic cells." - Wikipedia article: "Nucleus (cell)"So yes, a nucleus is an organelle. Although my textbook doesn't really seem to consider the nucleus as an organelle, it treats it like its something separate... but it makes more sense that its considered an organelle.
Mammalian cells have nuclei. But red blood cells lack
The mitochondria is the organelle that provides the energy needed for muscle contraction through the production of adenosine triphosphate (ATP), which is the energy currency of the cell.
Yes, plant cells have nuclei. The nucleus is a membrane-bound organelle found in the cells of plants and animals, which houses the genetic material (DNA) of the cell. It is essential for controlling cell functions and directing cellular activities.
Chloroplasts are the main organelles used, along with ribosomes, nuclei, and the endoplasmic reticulum.
Yes. The term organelle really is a rather vague term that denotes any specialized subunit within a cell and nuclei are definitely specialized subunits designed for enclosing and protecting the cell's complement of DNA.
A nuclear pore is not a cell. It is not even an organelle, only a characteristic/part of the nucleus. I think you mean are cells with nuclei prokaryotic. No, possessing nuclei is a characteristic of eukaryotic cells. If you need more information, see the related link.
There are 20,000 species of ferns. Ferns are vascular.
The organelle that would pellet first during centrifugation is the nucleus. Nuclei are typically the largest and heaviest organelles in the cell, and they have a high density, causing them to sediment first at lower centrifugal forces.
Autotrophic organisms are animals or plants that can create their own energy from the Sun. The organelle most common in these organisms are chloroplasts.
