<h2>Question:-</h2><h3> Which structure is found in all animal cells?</h3>
<h2>Answer :- Centrioles </h2>
<h2>Explanation:- </h2>
- They are barrel shaped cell organelles only found in animal cell
- There function is to help in division of cell membrane by forming microtubules which help in division of chromosomes ( spindle fibres)
- They play role in arranging microtubules which act as endoskeleton of the cell
- They also help in formation of cell structure like cilia and filaments
Answer:

A the cell, definition - the cytoplasmic division of a cell at the end of mitosis or meiosis, bringing about the separation into two daughter cells.
Explanation:
1.Structure of virus- Schleiden and Schwann could not explain the structure and functioning of virus cell. They said that the function of body is coordinated function of cell which is not true in the case of virus because it only starts it's functioning when hosted by bacterial, plant or animal cell.
2.Prokaryotic cells- The cell theory do not holds true in the case of Pk cells because they do not have any well defined nucleus.
3.Multinucleate condition- The cell theory says that each cell have A NUCLEUS, but there are certain cells like tapetal cells that are coenocytic.
4.Cells without nucleus- Acc to cell theory there should be a nucleus in every cell, but human RBCs, sieve tubes of angiosperm are some of the cells lacking nucleus.
Answer:
D
Explanation: Because a nurse doesn't have credentials like going to medical school nor residency, so nurse doesn't sound right.
