Microsporogenesis differs from megasporogenesis in flowering plants primarily in that:

The correct answer is A: Microsporogenesis produces four functional spores while megasporogenesis produces only one. In microsporogenesis, all four microspores produced from meiosis are typically functional. In megasporogenesis, usually three of the four megaspores degenerate, leaving only one functional megaspore.

The compensation point in photosynthesis is defined as the light intensity at which:

The correct answer is B: Rate of photosynthesis equals the rate of respiration. At compensation point, the rate of CO2 fixation in photosynthesis equals the rate of CO2 release in respiration, resulting in net zero gas exchange.

Companion cells are exclusively associated with which of the following?

The correct answer is B: Sieve tube elements. Companion cells are specialized parenchymatous cells that remain alive and are attached to sieve tube elements in the phloem.

The cork tissue in plants is derived from which meristematic tissue?

The correct answer is C: Cork cambium (Phellogen). Cork tissue (phellem) is produced outward by the cork cambium (phellogen), which is a lateral meristem.

The integuments of an ovule serve primarily to:

The correct answer is B: Develop into the seed coat after fertilization. Integuments are the outer layers of the ovule that develop into the seed coat (testa) after fertilization, providing protection to the seed.

C Stomata

D Xylem vessels

Correct Answer: B. Cuticle
