Test your understanding with targeted questions

Question 1 Easy

Which organelle is known as the "brain" or "control center" of the cell?

  • Answer: The nucleus.
  • Hint: It contains the cell's genetic information (DNA).

💡 Hint: It contains the cell's genetic information (DNA).

Question 2 Easy

What is the primary function of the Mitochondria?

  • Answer: To produce energy (ATP) through cellular respiration.
  • Hint: It is often called the "powerhouse" of the cell.

Question 1

Which organelle is found in plant cells but not typically in animal cells?

  • Type: mcq
  • Options: A) Mitochondria, B) Nucleus, C) Chloroplast, D) Ribosome
  • Correct Answer: C
  • Explanation: Chloroplasts are specialized for photosynthesis, a process only plants (and some algae) perform.
  • Hint: This organelle is green and uses sunlight to make food.

💡 Hint: This organelle is green and uses sunlight to make food.

Question 2

True or False: Lysosomes are responsible for protein synthesis.

  • Type: boolean
  • Options: True, False
  • Correct Answer: False
  • Explanation: Lysosomes contain digestive enzymes to break down waste; Ribosomes are the organelles that synthesize proteins.
  • Hint: Lysosomes are like the "janitors" or "recycling bins."

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

The Poisoned Factory: A cell is exposed to a toxin that specifically destroys Ribosomes. Predict the immediate effect on the cell's ability to function and explain your reasoning.

  • Solution: The cell would immediately stop being able to produce proteins. Since proteins are essential for almost every cell function (enzymes, structure, signaling), the cell would eventually die because it could not repair itself or carry out chemical reactions.
  • Hint: What is the "product" that ribosomes make?

💡 Hint: What is the "product" that ribosomes make?

Challenge 2 Hard

Organelle Identification: You are looking at a cell under a high-powered microscope. You see a large, central fluid-filled sac that is pushing all the other organelles against the cell wall. Identify the organelle and the type of cell you are looking at.

  • Solution: The organelle is a Large Central Vacuole, and the cell is a Plant Cell.
  • Hint: Only one type of cell has a vacuole large enough to push other parts aside for structural support.

💡 Hint: Only one type of cell has a vacuole large enough to push other parts aside for structural support.
