What does the nucleolus in a cell organelle do?
The nucleolus is responsible for producing ribosomal RNA (rRNA) and assembling ribosomes, which are essential for protein synthesis in the cell. It is found inside the nucleus and plays a crucial role in protein production.
Is mitochondria larger than a nucleolus?
Mitochondria are typically larger than a nucleolus in terms of size. Mitochondria are membrane-bound organelles responsible for energy production, while the nucleolus is a smaller structure found within the nucleus of a cell that is involved in the production of ribosomes.
What is an analogy for a nucleolus?
if the ribosmes are the factory, than the nucleolus is the construction workers that make the factory. if the whole cell is the factory and the ribosomes are the factpry workers, the nucleolus is the manager in charge of hiring and/or training new workers.
Describe the changes that have occurred to the nucleolus and nuclear membrane from interphase to prophase?
During interphase, the nucleolus is visible and active in producing ribosomes, while the nuclear membrane is intact, surrounding the nucleus. As the cell enters prophase, the nucleolus begins to disappear as the ribosomal RNA is dispersed throughout the nucleus. The nuclear membrane also breaks down, allowing the chromosomes to condense and become visible.
Nucleus vs nucleoid?
in microbiology and genetics, a plasmid is a DNA molecule that is separate from, and can replicate independently of, the chromosomal DNA. The nucleoid is an irregularly-shaped region within the cell of a prokaryote that contains all or most of the genetic material

Why is the cell wall not present in animals?
Animals cells use a cell membrane rather than a cell wall. Animals have more active metabolisms than plants do, and therefore they need faster diffusion from cells to circulatory systems, than they would get with cell walls.
Are protozoa prokaryotes or eukaryotes?
Protozoa are eukaryotic.A cell on the basis of organisation of its nucleus can be of two kinds:1.PROKARYOTIC2.EUKARYOTICPROKARYOTIC CELL: in prokaryotic cell [unorganised nucleus] no nucleus is present; instead a ring like nucleic acid DNA is present. it is also termed as nucleoid. all cell organelles are absent except ribosomes. Examples: bacteria, blue green algae.EUKARYOTIC CELL: in eukaryotic cells a true nucleus is present. A true nucleus has four parts namely: nucleolus, nuclear membrane, nuclear reticulum, nucleoplasm. All cell organelles are present in a eukaryotic cell. Examples: amoeba, spirogyra.

How is the nucleolus like a vice principle in a school?
the principal, because he/she is the one who controls what happens in the school, just like the nucleus
What is the difference between prokaryotic cell and eurokaryotic cell?
The main difference is that Eukaryotic cells have a nucleus. Or to be more accurate Eukaryotic cells have membrane bound compartments in which metabolic activity takes place. Such are membrane bound organelles like Mitochondria.
Can a cell only have one nucleolus?
Most cells have only one nucleolus however there are exceptions.very long nerve cells.certain flat worm species have large amoebae like cells with more than one nucleolusthe slime molds have multi-nucleated cells.

What is the physical description of the nucleolus?
The Nucleolus is a 'nuclear organelle' inside of the eukaryotic Cell's nucleus. It's primary role is to synthesize messenger Rna which is rapidly exported, via the Nuclear Pores, to the nearly situated Ribosome peppered Rough Endoplasmic Reticulum.The nucleolus(plural nucleoli) is a non-membrane bound structure and is the centre of the cell. It is composed of proteins and nucleic acids found within the nucleus of eukaryotic cells. Its function is to transcribe ribosomal RNA(r RNA) and assemble it within the cell.
What is the barrier between inside of the cell and its enviorment?
There are more than one kind of cell. If it is an animal or bacteria cell, than the cell membrane separates it. If it is a plant cell, than the cell wall separates it. go to www.cellsalive.com for more on that
