Question

Plants cells are differ from animal cells in having
A. Cell wall
B. Plastids
C. A large central vacuole
D. All of these

Answer 1

Hint: A plant cell has rigid wall, plastids like chloroplast, leucoplast and chromoplasts and one large central vacuole. All these structures are absent in animal cells.

Complete answer: Because of the presence of eukaryotic cells plants and animals are very much similar to each other. Plasma membrane, nucleus, cytoplasm, mitochondria are generally present in eukaryotic cells. The main difference between plant and animal cells is the presence of rigid cell walls. Plant cells have protein and cellulose around them, while other cells have cell walls around them.
 

Specific organs work together to form an organ system. Organ system varies accordingly in different organisms. Usually a plant cell is larger than animal cells (from 10- 100 micrometer). Animal cells vary from 10-30 micrometer.

Hence, the correct answer is option (D).

Note: The structure of a plant is fixed while the structure of animal cells is flexible. Plant cells store their energy in the form of starch while animal cells store their energy in the form of glycogen. Nucleus is present in the centre of the animal cell while it is present on one side inside the plant cell.
