Introduction:
The major distinction between cells is of them being prokaryotic or eukaryotic. Within the eukaryotes major distinction is done based on the presence or absence of cell wall.
Answer to Problem 1MCQ
Correct answer:
The cell wall is not present in all the cell types. Therefore, option c. is correct.
Explanation of Solution
Reason for the correct statement:
The cell wall is not observed in all the cells. It is found in all the prokaryotes, plant cells and
Option c. is given as “Cell wall”.
As, “cell wall is a feature not found in all cells”, is the right answer.
Hence, option c. is correct.
Reasons for the incorrect statements:
Option a. is given as “Proteins”.
Proteins are found in each and every cell. It is the
Option b. is given as “Ribosomes”.
Ribosomes are the site of protein production and hence are found in all the cell types. So, it is a wrong answer.
Option d. is given as “Cell membrane”.
The cell membrane is found in all the cells. A cell may not have the cell wall or capsid but all have the cell membrane. So, it is a wrong answer.
Hence, options a., b., and d. are incorrect.
The cell wall is a cellular feature not found in all the cells.
