What are some questions to ask about cells?

Cell Day Frequently Asked Questions

• What is the smallest cell?

• What is the largest single cell and how big is it?
• How many different types of cells can be found inside the human body?
• Which living organism has the most cells?
• Do any cells have natural color?
• What color is a nucleus?

What is protoplasm with example?

The protoplasm is the cell’s living content. It is composed primarily of biomolecules such as nucleic acids, proteins, lipids, and carbohydrates. It also has inorganic salts and water molecules. The protoplasm is surrounded by the cell membrane.

Why protoplasm is called the basis of life?

‘Protoplasm is the physical basis of life’ was stated by Huxley. This is because the protoplasm is the matrix or the substratum where we find all the organelles of the cell suspended and is the medium for all the activities of the cell.

Is protoplasm a jelly like substance?

Protoplasm is the living part of the cell, which comprises of different cellular organelles. It is a jelly-like, colourless, transparent and viscous living substances present within the cell wall.

Do cells have Colour?

Are cells specific colors or can they be any color? In nature, most cells are transparent and without color. Animal cells that have a lot of iron, like red blood cells, are deep red. Cells that contain the substance melanin are often brown.

What are some good biology questions?

Biology

• Are gender traits completely a result of societal expectations?
• Are there any parts of the human body that get oxygen directly from the air and not from the blood?
• Are there nuclear reactions going on in our bodies?
• Can humans ever directly see a photon?
• Can I turn my cat into a diamond?

What would happen if the protoplasm is lost from the cell Why?

If the plasma membrane ruptures or breaks down, the cell will not be able to exchange material from its surroundings by diffusion or osmosis because it acts as a mechanical barrier. Thereafter, the protoplasmic material will be disappeared, and the cell will die. Was this answer helpful?

How many types of protoplasm are there?

Protoplasm exists in three forms: in the solid state, the liquid state and sometimes in a combined solid and liquid state. The physiological state of the cell determines which form it is in at any given time.

Who discovered protoplasm in cell?

Dujardin
Dujardin in 1835 discovered protoplasm but in 1839 it was J.E. Purkinje who coined the word protoplasm. Protoplasm is the colourless material comprising of all the living components of the cell.

Does protoplasm include cell membrane?

The protoplasm is surrounded by the membrane of the cells. The protoplasm refers to the materials contained within the cell membrane, i.e. the prokaryotic cytoplasm, since prokaryotes do not have a distinct nucleus and other cytoplasmic organelles.

Is protoplasm present in animal cell?

In animal cells, the whole cell is made of protoplasm, surrounded by a cell membrane. Protoplasm in living beings is made up of about 75–80% water.

Are organs pink?

Oxygenated blood circulates throughout tissues giving all organs a pink-red hue,14–17 more strikingly observed in the skin, mucosae, retina, the fresh gray matter of the brain, the red nucleus of the midbrain, the spleen, and the placenta.

In which solution does protoplasm shrink?

hypertonic solution
Shrinking of protoplasm from cell wall under influence of hypertonic solution is.

What is the protoplasm surrounding the nucleus called?

In eukaryotes, the portion of protoplasm surrounding the cell nucleus is known as the cytoplasm and the portion inside the nucleus as the nucleoplasm.

Do all cells have protoplasm?

Max Schultze in 1861 proposed the “Protoplasm Doctrine” which states that all living cells are made of a living substance called Protoplasm.

Where is protoplasm located?

Do viruses have protoplasm?

The virus is a small infectious agent which is made of protein coat called capsid that surrounds the genetic material. Some of the viruses also contain an envelope that surrounds the capsid. Protoplasm is absent in virus. So the correct answer is ‘protoplasm’.
