MCQs on Animal Cell

The MCQs asked in a particular competitive examination may seem to be easy but they contain critical thinking also. The MCQs on animal cells are mostly asked in the NEET examination. In order to get through these MCQs, you should get some basic tips. These include, 

• NCERT be at your fingertips.

• While attending the examination, try to find the most inappropriate option and neglect it. This would help you to find out the right option easily.

• Practice the previous year asked questions. There are many sample paper books available in the market or you can simply download them from the internet.

• Do not take the risk of making more mistakes as each mistake costs you a -1. 

What is Cell?

In the year 1665, Robert Hooke noticed these cells in a bark of a tree which later led to the study of this branch of science widely. He named them so, because of their resemblance to the cells inhabited by Christian monks in a monastery.

Cells are widely known as building blocks of life. The branch of science which deals with the study of cells, it's types and functioning is widely known as cell biology.

Cells are broadly classified into two types:

●       Eukaryotic ( comprises of the nucleus)

●       Prokaryotic ( do not have a nucleus but have a nucleoid)

Animal Cells

The animal cells are the basic structural and functional units of animal tissues and organs.

These cells come under the eukaryotic division of the cell which consists of a nucleus. These contain both a membrane-bound nucleus as well as other membrane-bound organelles which are absent in the prokaryotic classification. The organelles present in the cells are suspended in the cytoplasm enveloped by a plasma membrane.

The organelles present in the animal cells contribute to the different types of functions that are essential for the survival of the cell. The organelle functioning is the same in both plants and animals as they both are eukaryotic and contain the same type of organelles. These cells do not contain a rigid cell wall. Due to this factor, animals acquire a greater diversity of cell types, tissues, and organs.

These cells simply have a cell membrane but have no cell wall. The other organelles present in an animal cell are chloroplast, vacuoles, nucleus, mitochondria, etc.

A Few More MCQs

Animal cells are eukaryotic cells lacking a cell wall but possess a true, membrane-bound nucleus in addition to other cellular organelles. They show the presence of DNA within the nucleus. Animal cells consist of organelles and cell structures that are responsible to carry out dedicated functions required for the proper functioning of the cell.
