Can a nucleus have more than one nucleolus?
The occurrence of more than one nucleolus within the cellular nucleus (polynucleolarity) is a well-known phenomenon during the proliferative cell cycle, both under normal and pathological conditions (e.g. neoplasia). It can also be observed in neuronal nuclei at early stages of their maturation.

Is a nuclei a nucleus?
In cell biology, the nucleus (pl. nuclei, from Latin nucleus or nuculeus, meaning kernel or seed) is a membrane-bound organelle found in eukaryotic cells.
Can a cell have two nucleoli?
Although usually only one or two nucleoli can be seen, a diploid human cell has ten nucleolus organizer regions (NORs) and could have more nucleoli. Most often multiple NORs participate in each nucleolus.

Plant and animal cells are eukaryotic, meaning that they have nuclei. Eukaryotic cells are found in plants, animals, fungi, and protists. They generally have a nucleus—an organelle surrounded by a membrane called the nuclear envelope—where DNA is stored.
What’s the difference between the nucleus and the nucleus?

What is difference between nucleus and Nucleoid?
Nucleus vs Nucleoid
A nucleus is a membrane-bound organelle that houses the genetic material of eukaryotes in DNA. The nucleus consists of protein fibres or the DNA inside chromatin fibres. Nucleoids contain the genetic material of prokaryotes in the cytoplasm. The nucleoids usually consist of a single chromosome.
What is a nucleus similar to in real life?
The nucleus is like the principal of a school, because the nucleus controls the cell like the principal controls the school. 2. Ribosome- The site where amino acids are hooked together to make proteins. Ribosome are like a factory, because ribosomes make proteins like factories make different products.
What is nucleus like analogy?
Analogy: The nucleus is like the brain of a human because the brain controls the actions of the body like the nucleus controls the cell. Analogy: Mitochondria act like a power plant because they both transform other materials to make energy.
What are cells compared to?
Cells are Like Cars
The structure its body provides makes it comparable to a cell wall. You can compare the windshield and windows to plasma membranes, since they protect the inside of the car from invaders like insects and dirt.
What can you compare a cell membrane to?
- The cell membrane is like a security guard, because the cell membrane controls what goes in and out of a cell like a security guard controls who goes in and out of the gate.
- The cell membrane is like the roof on a house because it protect the house from storms and anything else.
What can cytoskeleton be compared to in real life?
The cytoskeleton holds the shape of the cell. The cytoskeleton is like the beams of a house because they help the house hold it’s shape.
What candy represents cytoplasm?
We chose icing to represent the cytoplasm because it’s sticky, so the organelles can stay in place, and because the icing can cover the entire cake. The nucleolus was a bite-sized Three Musketeers chocolate bar.
What candy looks like a centrosome?
Try sprinkles for ribosomes, a hard ribbon candy for the Golgi body, jelly beans for lysosomes, a gumball for the centrosome, folded fruit roll-ups or gummy worms for endoplasmic reticulum, chocolate covered raisins for vacuoles, shoestring licorice for microtubules and gumdrops or orange candy slices for mitochondria.
How do you make a candy animal cell?
Suggested candy for an edible cell model:
- Blue Mike and Ikes = mitochondria.
- Pink Mike and Ikes = smooth endoplasmic reticulum.
- Air Head Bites = vacuoles.
- Air Heads Xtremes = rough endoplasmic reticulum.
- Sour gummy worms = Golgi apparatus.
- Candy disc sprinkles = ribosomes.
- Cupcake = nucleus.
Can an atom have more than one nucleus?
That means, for the briefest of time, there is a radon nucleus and a helium nucleus still inside the “center” of the atom, i.e., two nuclei!
What is nucleus also known as?
The nucleus is called the control center of the cell. This is because it is responsible for maintaining the integrity of DNA. A large fraction of the genome comes from nuclear DNA. Thus, the nucleus controls much of the cell’s activities such as metabolism, growth, and reproduction.
What is inside a nucleus?
Inside the nucleus, chromatin (DNA wrapped around proteins, described further below) is stored in a gel-like substance called nucleoplasm. Enclosing the nucleoplasm is the nuclear envelope, which is made up of two layers of membrane: an outer membrane and an inner membrane.
Is DNA in the nucleus or nucleolus?
The nucleus contains DNA while the nucleolus contains RNA. 4. The nucleus has the chromosomes and cellular membranes while the RNA has the fibrillar centers, dense fibrillar centers, and the granular component.
