Question

A typical animal cell has :
A. Cell membrane
B. Cell wall
C. Permanent vacoule
D. Lysosome
E. Rough Endoplasmic Reticulum (RER) with Ribosomes attached
Choose the correct answer from the options given below :

• A. A and B only
• B. A and C only
• C. A and D only
• D. D, A and E only

Hint:

The three main features that easily distinguish a Plant cell from an Animal cell under a microscope are the presence of a rigid Cell Wall, green Chloroplasts, and a massive Central Vacuole.

Answer 1

The Correct Option is D

Step 1: Concept:
This question differentiates between the cellular anatomy of typical animal cells and plant/fungal cells.

Step 2: Step-by-step Explanation:

• All eukaryotic cells, including animal cells, are bounded by a flexible lipid bilayer called a Cell membrane (A).

• Animal cells contain membrane-bound organelles for protein synthesis, notably the Rough Endoplasmic Reticulum (E).

• Animal cells possess Lysosomes (D) to act as their primary intracellular digestive system.

• However, animal cells explicitly lack a rigid Cell wall (B), which is a defining feature of plant cells (cellulose) and fungal cells (chitin).

• Furthermore, animal cells do not have a large, Permanent central vacuole (C) used for maintaining turgor pressure; this is another hallmark of mature plant cells. (Animal cells may have small, temporary transport vacuoles).
Therefore, the features present in a typical animal cell are A, D, and E.

Step 3: Final Answer:
The correct combination is D, A, and E only, corresponding to option (D).
