Is vacuole an organelle?

A vacuole is a membrane-bound cell organelle. In animal cells vacuoles are generally small and help sequester waste products. In plant cells vacuoles help maintain water balance. Sometimes a single vacuole can take up most of the interior space of the plant cell.

What does the smallest cell look like?

Most cells are colorless and see-through. The size of a cell also varies. Some of the smallest are one-celled bacteria which are too small to see with the naked eye at 1-millionth of a meter (micrometer) across. Plants have some of the largest cells 10–100 micrometers across.

Which one is true for smallest cell?

Mycoplasma refers to a genus of bacteria which lack a cell wall and it is currently considered the smallest known cell at about 0.1 micron (µm) in diameter.

What is the smallest entity that exhibits?


The cell is the smallest entity that exhibits all the characteristics of life. Cells are very small (microscopic) but very complex. They can be single celled like bacteria or some protists or multicellular like plants and animals. To study cells we use the microscope.

Which of the following is the smallest micro?

Viruses are so small that most cannot be seen with a light microscope but must be observed with an electron microscope. That’s why the correct answer is Virus. Virus is the smallest microorganism.

What are membrane less organelles?

Membraneless organelles are distinct compartments within a cell that are not enclosed by a traditional lipid membrane and instead form through a process called liquid-liquid phase separation. … Keywords: P granules intrinsically disordered regions liquid phase separation non-membrane-bound organelles.

Which is the only organelle found in a prokaryotic cell?


Answer: (2) Ribosomes

The two distinct forms of cells are prokaryotes and eukaryotes. Eukaryotic cells contain organelles that are membrane-bound whereas prokaryotic cells do not. In both prokaryotic and eukaryotic cells the ribosome is the only organelle that can be seen.

What is the cytosol function?

Function. The cytosol has no single function and is instead the site of multiple cell processes. Examples of these processes include signal transduction from the cell membrane to sites within the cell such as the cell nucleus or organelles.

Which is smaller ribosomes or lysosomes?

Is peroxisome the smallest organelle?

In the liver peroxisomes are also involved in the synthesis of bile acids which are derived from cholesterol. – Ribosomes considered as the smallest organelle of the cell and associated with the outer layer of the cell wall these are known as Protein factories it plays a key role in Protein synthesis.

Which is the largest cell organelle in animal cell?


Nucleus is the largest organelle in the animal cell covering upto 10% of the cell volume.

Which organelle is called kitchen of the cell?


Chloroplasts contain chlorophyll and carotenoid pigments responsible for capturing the light energy that is necessary for photosynthesis. The chloroplasts are therefore known as the kitchen of the cell.

Which is known as brain of the cell?

The cell membrane is found in all cells that separates the interior of the cell from the outside environment. So we can say that the nucleus controls the cell and acts as the brain of the cell.
