What is the meaning of pistillate and staminate flower and types of gametes in them?
the staminate also known as the androecium is composed of the organs of the male reproductive system (flower). these are the anther and filament.
the pistillate on the other hand (gynoecium) is composed of the organs of the female reproductive system. these are the pistil, style and ovary.

Why can't a staminate produce seeds?
Staminate plants (male reproductive structures) cannot produce seeds because they lack the necessary structures for seed formation, such as the ovule and the embryo sac. Instead, staminate structures produce pollen, which is essential for fertilizing the ovules in the pistil of female plants for seed production.
What is the main effect of being an imperfect flower?
Imperfect flowers, which have either male (staminate) or female (pistillate) reproductive structures but not both, can limit the plant's ability to self-pollinate. This condition often necessitates cross-pollination with other plants, which can enhance genetic diversity and resilience. However, reliance on external pollinators can also make these plants more vulnerable to fluctuations in pollinator populations. Overall, the main effect of being an imperfect flower is the trade-off between increased genetic variation and reduced reproductive assurance.
What flowers have a pistil?
Members of the family Cucurbitaceae like melons and squashes have pistillate (female) and staminate (male) flowers on the same plant separately. On the other hand, in date palm the plants bearing pistillate flowers are separate.
What are the gametes in a flower?
In flowering plants, the gametes are the male and female reproductive cells involved in sexual reproduction. The male gametes are contained within pollen grains, produced by the anthers of the flower's stamens. The female gametes are found in the ovules, which are located within the ovary of the flower's carpels. When pollination occurs, the male gamete fertilizes the female gamete, leading to seed formation.
Where is the gamete made in the flower?
In flowering plants, gametes are produced in the reproductive structures of the flower. Male gametes (sperm) are formed in the anthers of the stamens, where pollen is produced. Female gametes (eggs) are located in the ovules, which are found within the ovary of the pistil. These structures are essential for sexual reproduction in plants.
What are the difference between staminate and pistillate flowers?
the staminate also known as the androecium is composed of the organs of the male reproductive system (flower). these are the anther and filament. the pistillate on the other hand (gynoecium) is composed of the organs of the female reproductive system. these are the pistil, style and ovary.
Is the hibiscus flower a pistillate flower?
2+2=1
Example of staminate flowers?
Cucumbers, holly, and chrysanthemums have staminate flowers. A staminate flower has working stamens, but not functioning carpels. This is sometimes referred to as a "male" plant. Most flowers have functioning stamens and carpels.
Is lilly a unisexual flower?
Lilies are generally considered unisexual flowers because they typically have either male (staminate) or female (pistillate) reproductive organs in separate flowers. Some species of lilies can exhibit both male and female characteristics within the same flower, but they are primarily classified as unisexual. This means that individual flowers usually produce either pollen or ovules, not both.
Why Can a staminate flower not produce seeds?
because it is not able to reach the water and soil
What are examples of pistillate flowers?
Examples of pistillate flowers include flowers of squash, cucumber, watermelon, and apple trees. Pistillate flowers typically have female reproductive structures such as ovaries, styles, and stigmas, but lack male reproductive structures like stamens.
Why can't a staminate produce seeds?
Staminate plants (male reproductive structures) cannot produce seeds because they lack the necessary structures for seed formation, such as the ovule and the embryo sac. Instead, staminate structures produce pollen, which is essential for fertilizing the ovules in the pistil of female plants for seed production.

Where are the male and female sex cells in the flower?
gametes
Where are the male and the female sex cells in the flower?
gametes
Where female gametes of flower formed?
Female gametes in a flower are typically formed in the ovule, located within the ovary of the flower. The ovule contains the egg cell, which is the female gamete. Pollination and fertilization occur to produce seeds within the ovary.
