I, II, and III

I. Commelina species possess cleistogamous flowers.

Cleistogamous flowers are a unique type of flower found in some plant species, including certain species of the genus Commelina. Cleistogamy refers to the condition where flowers self-pollinate without opening or relying on external pollinators. In cleistogamous flowers, the anthers and stigma are in close proximity, facilitating self-fertilization. This adaptation is beneficial in environments where pollinators may be scarce or unreliable. By self-pollinating, plants ensure reproductive success even without the need for pollinators.

II. Amorphophallus plants produce the tallest flowers.

Some species offer floral rewards by providing secure environments for egg-laying, as exemplified by the towering Amorphophallus flower, which can reach a height of approximately 6 feet. Amorphophallus is a genus of plants that includes species with impressive inflorescences. Some species within the genus are known for producing the tallest flowers in the plant kingdom. One such example is Amorphophallus.

III. Cucurbita is an example of a monoecious plant where both male and female flowers are borne on the same plant.

Cucurbita is indeed an example of a monoecious plant. Monoecious plants have separate male and female flowers on the same individual plant. In the case of Cucurbita, the male flowers and female flowers are borne on the same vine. Pollination occurs when pollen from the male flower reaches the stigma of the female flower, allowing for fruit development.
