NEET Botany Cell: The Unit of Life MCQs

A prokaryotic cell lacking MreB protein is most likely to exhibit which shape?

Which structural component of a prokaryotic cell exhibits the highest resistance to lysozyme digestion?

A novel unicellular eukaryote is discovered with an unusual Golgi apparatus. Instead of the typical cis-trans polarity, its Golgi cisternae appear randomly distributed throughout the cytoplasm. Which cellular process would be MOST severely impacted by this disorganized Golgi?

A mutation affects a eukaryotic cell's ability to add mannose-6-phosphate tags to proteins. Which organelle's function would be MOST directly compromised?

Certain eukaryotic cells possess extensive networks of both smooth and rough ER. Which of the following cell types would likely have the HIGHEST combined surface area of ER?

A researcher observes a eukaryotic cell lacking functional peroxisomes. Which of the following metabolic processes would be MOST directly affected?

Certain histone modifications are associated with actively transcribed genes. Which of the following combinations is MOST likely to be found in the nucleosomes of such genes?

A researcher isolates chromatin fibers and treats them with a nuclease that specifically cleaves linker DNA. Following this treatment, what would be the approximate size distribution of the DNA fragments observed?

The orientation of cellulose microfibrils in the cell wall plays a crucial role in determining cell shape. If a plant cell has cellulose microfibrils arranged predominantly perpendicular to the direction of cell elongation, what shape is the cell most likely to adopt?

Callose deposition is often associated with specific plant responses. Which of the following scenarios is LEAST likely to induce callose deposition?
