Which of the following is not a haploid phase of the angiosperm life cycle?
A
Sporophyte
B
Egg cell
C
Gamete
D
Pollen grain
Verified step by step guidance1
Understand the concept of haploid and diploid phases in the angiosperm life cycle. Haploid cells have one set of chromosomes, while diploid cells have two sets.
Identify the phases of the angiosperm life cycle. Angiosperms alternate between a haploid gametophyte phase and a diploid sporophyte phase.
Recognize that the sporophyte phase is diploid, meaning it has two sets of chromosomes, and is responsible for producing spores through meiosis.
Examine the other options: Egg cell, Gamete, and Pollen grain. These are all part of the haploid phase, as they contain only one set of chromosomes.
Conclude that the sporophyte is not a haploid phase, as it is the diploid phase of the angiosperm life cycle.
