Question

Name the type of gametes formed of the staminate or pistillate flowers.

Answer 1

Plants have gametes which, for this plant species, contain half the normal number of chromosomes. The male gametes are located on the anthers of flowers within tiny pollen grains. Female gametes are present in a flower's ovules. The mechanism that brings these male and female gametes together is pollination.

Complete answer:
The one with no female reproductive part, i.e. the pistils, is a staminate flower. Male gametes (pollen grains) are thus formed by such flowers. There are no stamens in a pistillate flower, so they only contain female gametes (eggs).
A male flower, bearing only stamens, is a staminate flower. The female is a pistillate flower, bearing only pistils. A single plant (pronounced moan-EE-shus) has different male and female flowers on the same plant.
The female is a pistillate flower, bearing only pistils. A single plant (pronounced moan-EE-shus) has different male and female flowers on the same plant. Plants that are dioecious (die-EE-shus) on separate plants have either staminate or pistillate flowers.

Additional Information: Monoecious plants have male flowers and female flowers on the same plant in distinct structures. "Mono" means one-and literally "one house" is the expression "monoecious." The same plant houses various flowers, some of which are male, others female.
Dioecious plants on various plants house the male and female flowers. They have male plants (with only male flowers) and female plants (with only female flowers), so not only do the plants have different male/female flowers. Asparagus and Hollies are dioecious.

Note: Gametes are produced inside established organs in higher plants, the anther for the male containing the haploid pollen and the ovule for the female containing the embryo sac and the progenitor of the seed.
