Question

The following diagram shows cells of onion peel, label the cell wall, nucleus and cytoplasm.
The following diagram shows human cheek cells, label the parts as observed by you.

Answer 1

Hint: The diagrams mentioned above are the internal structure of an onion peel and human cheek cells. In order to label them, we need to understand its anatomy and know about various structures present in it. Onion peel is an example of a plant cell whereas a human cheek cell is an example of an animal cell.

Complete answer:
The plant cell usually consists of an outer cell wall which is rigid and helps in protecting the internal contents of the cell. Inside the cell, the liquid matrix is called a cytoplasm in which all the cell organelles and nucleus are present.Nucleus is a membrane bound organelle that contains DNA and is present only in eukaryotes. The tiny dot-like structure in the above diagram is the nucleus of the cell. Now coming to animal cells,the above mentioned diagram contains the same structures found in plant cells that are the cytoplasm, nucleus whereas cell membrane and nuclear membrane are found in addition. These are structures found in above diagrams and now let us label them.

Note:
Although plant and animal cells are similar in their cell structure, there exists few differences between them. The plant cell has a cell wall which is absent in the animal cell and instead cell membrane is present in it. The plant cell also contains large vacuoles and chloroplasts which are not found in animal cells.
