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.

  • 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.

Excretion and Reproduction GK Level 3: Biology Practice Questions

Excretion and Reproduction GK Quiz Level 3 is an advanced General Awareness biology set on how humans and plants remove wastes and how living organisms reproduce. It uses statement, matching and sequencing formats on nephron function, the path of urine, asexual modes and flower types. Aptitude360 gives a full explanation with each answer.

Topics covered in this Excretion and Reproduction Level 3 set

  • Human excretory system: kidneys, ureter, urinary bladder and urethra
  • Nephron and Bowman's capsule: formation of filtrate and re-absorption of glucose, amino acids and salts
  • Artificial kidney and hemodialysis when the kidneys fail
  • Excretion in plants: transpiration, wastes stored in vacuoles, resins and gums
  • Asexual modes: binary and multiple fission, budding, fragmentation, regeneration, spores and vegetative propagation
  • Pollination, fertilisation and fruit formation in flowering plants, with unisexual and bisexual flowers

Key excretion and reproduction concepts to revise

  • Order of steps from filtration in the nephron to the release of urine
  • Amoeba and Leishmania by binary fission, Plasmodium by multiple fission, Rhizopus by spores
  • Hydra by budding and regeneration, yeast by budding, Spirogyra by fragmentation
  • Sugarcane, rose and grapes can be grown by vegetative propagation
  • The placenta passes nutrition from the mother's blood to the embryo

Revision tips for excretion and reproduction GK

  • Draw the urine pathway from kidney to urethra and label each organ's role
  • Keep a table of organisms against their asexual mode, since matching items often mix them up
  • Learn what each flower part becomes after fertilisation: ovule to seed, ovary to fruit

Who this Level 3 biology set suits

General Awareness aspirants who have finished the basic levels and want tougher, exam-style biology statements to check their accuracy.

FAQs about Excretion and Reproduction – GK Quiz with Answers – Level 3

What is the functional unit of the kidney?
The nephron is the basic filtering unit of the kidney. Its cup-shaped Bowman's capsule collects the filtrate, from which useful substances like glucose and amino acids are re-absorbed.
What is the difference between excretion and reproduction?
Excretion is the removal of harmful metabolic wastes from the body, such as urea through urine. Reproduction is the process by which organisms produce new individuals of their own kind.
How does Plasmodium reproduce?
Plasmodium, the malaria parasite, reproduces asexually by multiple fission. It divides into many daughter cells at the same time.
Which plants have unisexual flowers?
Papaya and watermelon bear unisexual flowers, which have either stamens or a pistil. Mustard and hibiscus bear bisexual flowers with both parts.
