Which pair correctly identifies the gametes that unite to form new plant offspring?

• Pollen and ovum unite during fertilization

• Petal and receptacle unite during fertilization

• Anther and sepal unite during fertilization

• Stigma and filament unite during fertilization

In flowering plants, what is the male gamete involved in fertilization?

• Pollen released from the anther

• Ovum found inside the ovule

• Nectar produced by petals

• Chloroplasts within leaf cells

During sexual reproduction in flowering plants, what role does the ovum play?

• It is the female gamete that fuses with pollen

• It transports pollen to the stigma surface

• It forms the anther that produces pollen

• It attracts pollinators with sweet nectar

Which statement best describes a key advantage of sexual reproduction shown in the diagram?

• It guarantees identical offspring every generation

• It produces high genetic variation in offspring

• It removes all harmful genes from a population

• It ensures rapid population growth in all species
