Question

With the labelled sketch briefly write the life cycle of angiosperm plant

Answer 1

The adult, or sporophyte, phase is the main phase of an angiosperm's life cycle. As with gymnosperms, angiosperms are heterosporous. Therefore, they generate microspores, which will produce pollen grains as the male gametophytes, and megaspores, which will form an ovule that contains female gametophytes.

Answer 2

Angiosperm Life Cycle.

• ... Like ferns, the dominant part of the life cycle is the sporophyte.
• Flowering plants produce haploid spores.
• Microspores are produced within the anthers whereas the megaspores are produced within the ovule.
