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 25-minute clock, a question palette and full screen, and your score, the key and the solutions arrive when you submit.

Untimed

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.

Timed CBT

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

  • A clock that does not pause. 25 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.

About this test

Plant Physiology GK Practice Quiz Level 1: Photosynthesis and Plant Hormones

This Level 1 quiz builds a basic understanding of plant physiology: how plants make food, move water and grow. It covers photosynthesis, stomata and guard cells, xylem and phloem, meristems, plant hormones and tropisms. Aptitude360 explains every answer, so beginners can learn the reasoning as they practise.

What this plant physiology basics quiz covers

  • Photosynthesis: chlorophyll, sunlight, carbon dioxide and water, oxygen release and starch storage
  • Stomata, guard cells, gas exchange and transpiration
  • Xylem and phloem as conducting tissue, transpiration pull, root pressure and translocation
  • Apical, lateral and intercalary meristems, and parenchyma as a permanent tissue
  • Plant hormones: auxin, gibberellins, cytokinins and abscisic acid
  • Tropisms and movements: phototropism, geotropism, hydrotropism, chemotropism, pea tendrils and Mimosa

Key concepts in plant physiology to revise

  • Water is split into hydrogen and oxygen during photosynthesis
  • Desert plants take up carbon dioxide mainly at night
  • Xylem carries water and minerals upward, while phloem carries food
  • Abscisic acid inhibits growth and causes wilting of leaves

Revision tips for plant physiology GK

  • Make a table of each hormone with where it is found and its main effect
  • Pair each tropism with its stimulus: light, gravity, water, chemicals or touch
  • Remember that cambium is the lateral meristem that increases girth

Who should take this Level 1 quiz

Beginners in General Awareness biology who want to set up the basics before moving to harder levels.

FAQs about Plant Physiology – GK Quiz with Answers – Level 1

What is plant physiology?
Plant physiology is the branch of botany that studies how plants function, including photosynthesis, transport of water and food, growth and responses to stimuli.
Which pigment absorbs light for photosynthesis?
Chlorophyll is the green pigment that absorbs light energy for photosynthesis. It is found in chloroplasts.
What is the difference between xylem and phloem?
Xylem carries water and minerals from the roots to the upper parts of the plant. Phloem carries food made in the leaves to other parts.
Which plant hormone inhibits growth?
Abscisic acid inhibits growth. Wilting of leaves is one of its effects.
