Which organelle is the most prominent and important structure in a cell and also acts as the control Centre of the cell and why?


Which of the following organelles releases energy from sugars and is therefore called the powerhouse of the cell?


Which organelle would you expect to find in plant cells but not animal cells?


What surrounds and protects a cell?

The outer lining of a eukaryotic cell is called the plasma membrane. This membrane serves to separate and protect a cell from its surrounding environment and is made mostly from a double layer of proteins and lipids, fat-like molecules. The cytoskeleton is an important, complex, and dynamic cell component.

Is ribosome a true organelle?

Ribosomes is not a true organelle.

What is difference between organ and organelle?

Which organelle is the major difference between an organ and an organelle? Organ is a collection of tissues performing specific functions in a human body. On the contrary, organelles are cellular structures performing specific functions within the cell.

Is nucleolus an organelle?

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

Is there DNA in nucleolus?

The nucleolus is the central portion of the cell nucleus and is composed of ribosomal RNA, proteins and DNA. It also contains ribosomes in various stages of synthesis. The nucleolus accomplishes the manufacture of the ribosomes.

Is nucleolus a permanent structure?

– 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.

Do bacteria cells have a nucleolus?

no membrane bound organelles- but there are numerous inclusions and granules. Numerous small ribosomes in cytoplasm. many membrane bound organelles- lysosomes, mitochondria (with small ribosomes), golgi bodies, endoplasmic reticulum, nucleus. Bacteria, of course, have no nucleus and therefore also nuclear membrane.

What is the function of Nucleous?

The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information.

What is a main function of the nucleolus?

The nucleolus is a dynamic membrane-less structure whose primary function is ribosomal RNA (rRNA) synthesis and ribosome biogenesis.
