What can a nuclear envelope be compared to in real life?
The nucleus can be compared to the CEO of a company. A CEO oversees all of the company’s activities and leads the direction in which it will grow, just as a nucleus does for a cell. Other analogies for this aspect of the nucleus include the brain or a command center.
What is the nucleus 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.
What would the nuclear envelope be in a school?
A nuclear membrane is like a hall monitor. The nuclear membrane is like a hall monitor who controls traffic in the halls. The golgi apparatus is like a school secretary.
Which best describes nuclear envelope?
The nuclear envelope is a single membrane, consisting of a phospholipid bilayer. Plasmadesmosomes in the nuclear envelope permit the exchange of macromolecules between the nucleus and the cytoplasm. All of the proteins of the cell are synthesized on ribosomes bound on the nuclear envelope.
Are ribosomes attached to the nuclear envelope?
The attached ribosomes make proteins that will be used inside the cell and proteins made for export out of the cell. There are also ribosomes attached to the nuclear envelope. Those ribosomes synthesize proteins that are released into the perinuclear space.
What is cytoplasm analogy?
Cytoplasm -is the fluid-like material inside the cell that contains all of the cell’s organelles. The cytoplasm is like a jello salad because the cytoplasm surrounds and suspends the cell’s organelles like the jello surrounds and suspends the fruit in the jello salad.
Which is the best analogy for the nucleus of a cell?
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 a school analogy for nucleus?
9. Endoplasmic Reticulum (E.R.) The nucleus is like the principal of a school, because the nucleus controls the cell like the principal controls the school.
What is a school analogy for cytoskeleton?
Cytoskeleton is like a interior school walls, stairs etc. Cytoskeleton is like the framework of the school, helping keep the building stay strong and keep its form. Ribosomes are like teachers in school. Ribosome helps to produce important proteins for a cell and teachers produce educated people.
What connects nuclear envelope?
The nuclear envelope is a double membrane composed of an outer and an inner phospholipid bilayer. The thin space between the two layers connects with the lumen of the rough endoplasmic reticulum (RER), and the outer layer is an extension of the outer…
What similarities occur between nuclear envelope and endoplasmic reticulum?
In addition, the outer nuclear membrane is functionally similar to the membranes of the endoplasmic reticulum (see Chapter 9) and has ribosomes bound to its cytoplasmic surface. In contrast, the inner nuclear membrane carries unique proteins that are specific to the nucleus.
What are the two main functions of nuclear envelope?
What is nuclear envelope and its function?
What is nuclear envelope and its function? The nuclear envelope (NE) is a highly regulated membrane barrier that separates the nucleus from the cytoplasm in eukaryotic cells. It contains a large number of different proteins that have been implicated in chromatin organization and gene regulation.
What does a nuclear envelope look like?
What does a nuclear envelope look like? The nuclear envelope is composed of two concentric lipid bilayer membranes separated by an intermembrane space of about 20-40 nm. This lamina looks like loosely woven hessian and is thought to help give strength and support to the nuclear envelope and possibly provide an anchor point for chromatin fibres.
What is the purpose of the nuclear envelope?
The primary nuclear envelope function is to maintain the integrity of the cell nucleus and provide a physical barrier between the nucleus and the cytoplasm. The nucleus is where all the genetic information is stored in a cell and is responsible for regulating cellular activities. Therefore, it is important that this is protected.
