Which organelle labeled X in the diagram?

Which organelle labeled X in the diagram?

The correct answer is the cell Membrane.

Which organelle is marked with an X lysosome?

lysosome nucleus

Which organelle is most likely the cause?


Which organelle is the control center of the cell?


What is the meaning of cell organelles?

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.

How a cell works like a factory?

A cell can be thought of as a “factory,” with different departments each performing specialized tasks. A cell’s plasma membrane regulates what enters or leaves the cell. The CYTOPLASM includes everything between the cell membrane and the nucleus.

Which organelle is most like a factory delivery driver?


Which is not a cell organelle?

Answers for Which of the following is not a cell organelle? The mitrochondrion, lysosome and E.R are all organelles contained in the cytoplasm which is not an organelle but a gel-like material where all chemical reactions take place.

What are 2 types of organelles?

Different Cell Organelles and their Functions

  • Plasma Membrane.
  • Nucleus/DNA.
  • Ribosome.
  • Mitochondria.
  • Vacuoles.
  • Cytoskeleton.
  • Plastids.
  • Endoplasmic Reticulum.

Is cytoplasm considered an organelle?

Cytoplasm is a thick solution that fills each cell and is enclosed by the cell membrane. All of the organelles in eukaryotic cells, such as the nucleus, endoplasmic reticulum, and mitochondria, are located in the cytoplasm. …

Is ribosome an organelle?

All living cells contain ribosomes, tiny organelles composed of approximately 60 percent ribosomal RNA (rRNA) and 40 percent protein. However, though they are generally described as organelles, it is important to note that ribosomes are not bound by a membrane and are much smaller than other organelles.

Why isn’t a ribosome considered an organelle?

Ribosomes are different from other organelles because they have no membrane around them that separates them from other organelles, they consist of two subunits, and when they are producing certain proteins they can become membrane bound to the endoplasmic reticulum, but they can also be free floating while performing …

Why ribosomes are called organelle?

Ribosomes are small membrane-less, granular organelles which normally occur in prokaryotes. In prokaryotes, they remain spread in the cytoplasm. This makes it an organelle. Since RER is itself an organelle ribosome are called as organelles within the organelle.

Is nucleolus an organelle?

The nucleolus: an organelle formed by the act of building a ribosome.

Is there a membrane around the nucleolus?

The Nucleolus Although structurally distinct, it is not surrounded by a membrane. It is the site of transcription of the genes for rRNA molecules, for which there are 400 genes in a diploid human cell, distributed in multiple tandem repeats on 5 different chromosomes.

Is there DNA in nucleolus?

The nucleolus is a ribosome factory, composed of deoxyribonucleic acid (DNA), ribonucleic acid (RNA), and protein .

Who discovered the nucleolus?

Felice Fontana

What is the nucleolus made up of?

Nucleoli are made of proteins, DNA and RNA and form around specific chromosomal regions called nucleolar organizing regions.

Where is the nucleolus found?

cell nucleus

Is nucleolus a permanent structure?

Answer. – Nucleolus is a ribosomal factory which means it synthesizes ribosomal subunits and then delivers them to other parts of the cell to form ribosome. – Nucleolus is a permanent structure present inside nucleus. It is a largest structure present inside the nucleus.

What is a main function of the nucleolus?

The nucleolus is the most conspicuous domain in the eukaryotic cell nucleus, whose main function is ribosomal RNA (rRNA) synthesis and ribosome biogenesis.

What is important for maintaining configuration of nucleolus?

In essence, UBF binding to DNA, along with active rDNA transcription, is sufficient to form a nucleolus in human cells.

What is the nucleolus analogy?

An analogy for the nucleolus is that the nucleolus is like a building materials manufacturer.

What is an example of nucleolus in real life?

Nucleolus. A real life example would be a cookbook because just like a cookbook shows you how to make food the nucleolus shows the cell how to make ribosomes. A real life example would be a garbage disposal because like the Lysosome the garbage disposal breaks down waste.

What human body part is similar to the nucleolus?

The Nucleolus The Golgi body helps to create and package large molecules used in other parts of the cell. This organelle is found in both plant and animal cells. the equivalent in the human body is the blood veins. The nucleolus in a cell is inside the nucleus and creates ribosomes.

What is a good analogy for chromosomes?

A chromosome is like a flash drive or a book because they store information.

What is the cell membrane like in real life?

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. 4. Cell Wall -Supports and protects the cell while still letting materials pass through it.

What is a good analogy for mitochondria?

An analogy for mitochondria is that the mitochondria is like a power plant, because they both produce energy.

What is a endoplasmic reticulum like in real life?

Thee proteins on the ribosomes collect in the Endoplasmic Reticulum to help transport the proteins throughout the cell. It is responsible for protein synthesis. A real life example of the Rough Endoplasmic Reticulum would be traffic on a highway.

What is endoplasmic reticulum similar to?

Both rough ER and smooth ER have the same types of membranes but they have different shapes. Rough ER looks like sheets or disks of bumpy membranes while smooth ER looks more like tubes. Rough ER is called rough because it has ribosomes attached to its surface.
