Monothecousanthers are found in Malvaceae family: Correct Statement

The statement is correct. Monothecous anthers are found in the Malvaceae family. Monothecous anthers refer to anthers that have only one locule, which means they have only one chamber where the pollen is produced. The Malvaceae family includes plants like hibiscus, cotton, and okra, and all of them have monothecous anthers.

Middle layer is ephemeral: Correct Statement

The statement is correct. The middle layer of the anther is indeed ephemeral, meaning it is short-lived and undergoes degeneration during the maturation of the anther. The anther consists of four main layers - the epidermis, endothecium, middle layer, and tapetum. The middle layer is located between the endothecium and tapetum. It plays a role in the development and nutrition of the pollen grains. However, as the anther matures, the middle layer degenerates and eventually disappears.

Amoeboid tapetum releases ubisch bodies: Incorrect Statement

The statement is incorrect. It is the glandular tapetum, not the amoeboid tapetum, that releases Ubisch bodies. The tapetum is a specialized layer of cells found in the anther. It provides nutrition to the developing pollen grains and produces various substances, including Ubisch bodies. Ubisch bodies are lipid-rich structures that accumulate within the tapetum cells and are eventually released into the locule. These structures play a role in pollen wall development.

Banana is a monocarpic plant: Incorrect Statement

The statement is incorrect. Banana is not a monocarpic plant. Monocarpic plants are those that flower, set fruits, and then die. However, bananas are perennial plants, meaning they live for multiple years and produce fruits repeatedly. Once a banana plant produces fruits, the pseudostem (the part above the ground) dies back, but the underground rhizome remains alive and produces new shoots that grow into new plants. These shoots develop into new pseudostems, which eventually flower and produce fruits. Therefore, bananas are considered polycarpic plants.
