Cell Organelles & Plant Biology MCQ Bank

This page provides focused MCQ practice for cell organelles, plant-cell structure, and foundational plant biology. The questions are designed to test whether learners can connect structure with function, identify organelles from clues, and avoid common misconceptions about plant-cell organization.

Before you begin

Revise nucleus, chromosome, mitochondria, plastid, ribosome, endoplasmic reticulum, Golgi body, vacuole, cell wall, plasma membrane, and basic plant tissue ideas. Pay attention to functional keywords such as photosynthesis, protein synthesis, respiration, storage, secretion, and cellular control.

Practice method

Answer each item first without looking at the explanation. After submission, read the answer explanation and write the concept behind the correct answer in one sentence. This will convert option-selection practice into real biology learning.

Cell Organelles & Plant Biology

⏱️ Matrix Time: 12 Mins

Q1. Which organelle is responsible for photosynthesis in plant cells?

a. Mitochondria b. Chloroplast c. Ribosome d. Peroxisome

Answer Explanation & Validity Logic: Chloroplasts contain chlorophyll and the thylakoid membrane system where the light-dependent reactions of photosynthesis occur.

Q2. Which structure maintains turgor pressure and provides structural support in plant cells?

a. Cell membrane b. Central vacuole c. Nucleus d. Golgi apparatus

Answer Explanation & Validity Logic: The central vacuole in plant cells stores water and solutes; when full, it exerts turgor pressure against the cell wall, maintaining rigidity.

Q3. Which cell organelle is known as the 'powerhouse of the cell' due to ATP production?

a. Nucleus b. Chloroplast c. Mitochondria d. Lysosome

Answer Explanation & Validity Logic: Mitochondria generate ATP through cellular respiration, earning them the title 'powerhouse of the cell' across both plant and animal kingdoms.
