Reproduction in Human Beings MCQs

Q1. Which organ/part has the function: 'produces sperm and testosterone'?

• A.testis
• B.oviduct (fallopian tube)
• C.uterus
• D.placenta

Answer: A. testis

What is the textbook's take? Asexual = single parent -> identical offspring (binary fission, budding, fragmentation, spores, vegetative propagation); sexual = two gametes -> zygote with variation; matching the stem's described feature against this list => the option answering the question = testis. Does that line up with one of the options? Yes - Correct. And the rest? option B) 'oviduct (fallopian tube)' is incorrect: oviduct (fallopian tube): site of fertilisation; option C) 'uterus' doesn't hold - uterus: where the embryo implants and develops. Pick: A) testis.

Q2. Which organ/part has the function: 'produces ova and female hormones'?

• A.ovary
• B.uterus
• C.placenta
• D.scrotum

Answer: A. ovary

First, read what's there - a typical biology numerical. We are after the quantity the stem asks for. Tool of choice - F = m*a, V = I*R, n = m/M, v = f*lambda, KE = (1/2) m v^2). Rearrange it for the unknown before substituting. Numbers in: F = m*a, V = I*R, n = m/M, v = f*lambda, KE = (1/2) m v^2). Common-sense check: recall the defining law / equation for the named quantity (e.g. Lock in option A) ovary. Trap-watch: option B) 'uterus' doesn't hold - uterus: where the embryo implants and develops; option C) 'placenta' is wrong because placenta: exchanges nutrients and wastes between mother and foetus.

Q3. Which organ/part has the function: 'site of fertilisation'?

• A.oviduct (fallopian tube)
• B.placenta
• C.scrotum
• D.vas deferens

Answer: A. oviduct (fallopian tube)
