Question

What would happen if the nucleus is removed from the cell?
A. The activities of the cell would not be controlled and die
B. The cell will not have a regular shape
C. The cell will not be able to store food and water
D. The cell will not be able to move

Answer 1

The nucleus is a double-membraned organelle that houses genetic material as well as other instructions for cellular activity. It is one of the largest organelles and is only found in eukaryotic cells.
Functions-
It is in charge of storing the cell's genetic material, or DNA.
It is in charge of coordinating a variety of key cellular tasks, including protein synthesis, cell division, growth, and a variety of others.

Complete answer:
Option A: A eukaryotic cell's nucleus is its master controller. Its primary purpose is to store genetic information in the form of DNA. It goes via transcription to produce RNA, which then goes through translation to produce proteins. Proteins are involved in a variety of biological processes, including the production of hormones and enzymes. As a result, without a nucleus, the cell will die.
So, option A is correct.
Option B: The cytoskeleton is a dynamic system that is involved in cell structure and form, organelle transport, and environmental responses. Polymeric actin filaments and microtubules, which are frequently tightly connected with the plasma membrane, are the most prominent components of the cytoskeleton.
So, option B is not correct
Option C: A cell's storage compartment is called a vacuole. Water, food, and trash are all stored in vacuoles.
So, option C is incorrect
Option D: Microtubules, actin filaments, and intermediate filaments make up a cell's cytoskeleton. These structures give the cell its shape and aid in the organization of its components. They also serve as a foundation for mobility and cell division.
So, option D is not correct

So, the correct answer is “Option A”.

Note:
Structure of nucleus-
The nucleus is surrounded by a double-membraned organelle known as the nuclear membrane/envelope.
The nucleolus is located within the nucleus and takes roughly $25\%$ of the volume.
Within the nucleus, chromatins are thread-like, dense structures that hold proteins and DNA.
The nuclear matrix, a network of fibres and filaments that performs functions comparable to the cytoskeleton, provides mechanical strength to the nucleus.
