Normal practice, or a Simulated test

Both use the same questions. Normal practice is untimed and needs no account: choose an option and the answer and solution appear at once. The Simulated test is the real computer-based format, with one 35-minute clock, a question palette and full screen, and your score, the key and the solutions arrive when you submit.

Every question on one page, loading as you scroll. Choose an option and see straight away whether it was right.

  • No timer. Nothing to start and nothing to submit. Stop whenever you like.
  • Answered as you choose. Tap an option and it is marked at once, with the correct answer shown.
  • Solutions in place. The explanation, and the video where one has been added, sit under the question.
  • Open to guests. Normal practice needs no sign-in.

The computer-based test format: one clock, a question palette, and a score the moment you submit.

  • A clock that does not pause. 35 minutes from the moment you begin, and the paper is submitted for you when it reaches zero.
  • Question palette. Answered, not answered and marked for review, section by section, as the real interface has it.
  • Full screen, proctored. The test takes over the screen; leaving it three times submits the paper.
  • Answers hidden until you submit. The key, the explanations and your score all arrive together at the end.

Cell Structure and Function GK Quiz Level 3: Cell Theory and Organelles

This Level 3 Cell: Structure and Function quiz checks whether you can place the history of cell biology in the right order and tell organelles apart by their roles. It is a general awareness biology set on Aptitude360 covering cell theory, the plasma membrane, plastids and prokaryotic versus eukaryotic cells. Every question has a written explanation.

Topics covered in this cell biology GK set

  • Chronological order of discoveries by Hooke, Leeuwenhoek, Brown, Purkinje, Schleiden, Schwann and Virchow
  • Matching scientists with their contributions and the years of those contributions
  • Cell theory as stated by Schleiden and Schwann, and Virchow's addition to it
  • Organelle roles: ATP production in mitochondria, protein making by ribosomes, packaging by the Golgi apparatus, digestion by lysosomes
  • Plastid types: chloroplasts for photosynthesis and leucoplasts for storage
  • Plasma membrane, cell wall, vacuoles and osmosis
  • Differences between prokaryotic and eukaryotic cells, and between plant and animal cells

Key cell structure concepts to revise

  • Hooke saw dead cork cells, while Leeuwenhoek first saw free-living cells
  • Robert Brown discovered the nucleus and Purkinje coined the term protoplasm
  • Mitochondria have their own DNA and ribosomes
  • Prokaryotes such as bacteria lack a nuclear membrane and membrane-bound organelles
  • Plant cells have a cellulose cell wall, plastids and a large central vacuole

Revision tips for cell structure and function

  • Build a timeline of cell discoveries and recite it in order, since sequence and matching questions depend on it
  • Pair each organelle with a single keyword, such as powerhouse for mitochondria or suicide bag for lysosomes
  • Make a two-column table of structures found only in plant cells and those common to both

Who should take this Level 3 cell quiz

Students preparing general science for competitive exams who have already covered cell basics and now want harder statement and match-type practice.

FAQs about Cell: Structure and Function – GK Quiz with Answers – Level 3

Who discovered the cell?
Robert Hooke discovered the cell when he observed small compartments in a thin slice of cork. He named them cells. The cells he saw were dead.
Which organelle is called the powerhouse of the cell?
Mitochondria are called the powerhouse of the cell because they release energy in the form of ATP. They also have their own DNA and ribosomes.
What is the difference between prokaryotic and eukaryotic cells?
Prokaryotic cells, such as bacteria, have no nuclear membrane and no membrane-bound organelles. Eukaryotic cells, found in plants and animals, have a true nucleus enclosed by a membrane.
What does the cell theory state?
Schleiden and Schwann proposed that all plants and animals are made of cells. Virchow later added that all cells arise from pre-existing cells.
