Answer 1

Answer:

Butomus genus plant flowers contain Amphitropous ovules.

Explanation:

Ovules are the structure that is the part of the flowers. Flowers are the reproductive parts of angiosperm or seed-bearing plants. It contains the diploid female reproductive cell called megasporocyte which forms the female gametophyte. The ovules are housed inside the round vase-shaped structure called the ovary. After fertilization, each ovule inside the ovary develops into seeds.

The ovules comprise three parts:

• the integuments: forms the outer layer of the ovule, the nucellus: female gametophyte develops inside it and the female gametophyte form in the centre of the nucellus.

Depending on the shape the ovules are categorized into six groups. One of them is Amphitropous ovules. Amphitropous ovules have a body that is curved. The ovule and the embryo sac resemble the shape of a horseshoe and are almost completely inverted on its stalk. Butomaceae is a family of plants that contains only one genus of plant called Butomus.

Plants under the genus Butomus have ovules that are Amphitropous in shape.
