Question

The proximal end of the filament of stamen is attached to the

• A. Thalamus or petal
• B. Placenta.
• C. Connective
• D. Anther

Answer 1

The correct option is A

Thalamus or petal

The correct option is A.

Explanation of the correct option:

1. All floral appendages are linked to the thalamus, which is the enlarged base of the stem.
2. The colored structural unit of the corolla is the petal.
3. An anther and filament make up a stamen.
4. The filament's proximal ends are linked to the thalamus or petals, while the distal end contains an anther.

Explanation of the incorrect options:

Option B

1. The placenta is an organ that links the developing fetus to the uterine wall, allowing the fetus to absorb nutrients, eliminate waste, and exchange gases through the mother's blood supply.
2. A healthy fetus and a successful pregnancy are dependent on proper vascular development in the placenta.

Option C

1. It is one of the four fundamental cells that make up an animal's body
2. It also has a mesodermal origin, consisting of a mixture of cells and interlacing protein fibres embedded in a mostly carbohydrate-based ground substance.
3. In simple terms, the connective tissue is a collection of cells that interlace and connect the body's numerous cells and structures.

Option D

1. The anther is connected to the stamen, which is a portion of a flower's male reproductive system.
2. The male stamen structure is made up of a filament, which is a long tube with an oval-shaped pollen-producing component called the anther attached to the apex.
3. The stamen is the male reproductive component of a flower.
4. It is made up of a long tube, a filament, and a pollen-producing structure near the end.

Final answer: The proximal end of the filament of the stamen is attached to the thalamus or petal.
