Question

1. what part of an angiosperm contains the plants sperm?

pollen
style

Explanation:

Pollen grains are produced by the male reproductive part of the flower (stamen). Inside the pollen grain, there are male gametes (sperm). The style is part of the female reproductive structure (pistil) and is a tube - like structure that connects the stigma to the ovary. The anther is the part of the stamen that produces pollen, but it is the pollen itself that contains the sperm. The pistil is the female reproductive organ of the flower which includes the stigma, style, and ovary.

pollen
