Question

Which of the following structures is NOT part of the pistil? (A) Ovule (B) Ovary (C) Style (D) Anther (E) Stigma

Short answer

The part of the flower that is not part of the pistil is the Anther (Option D).

Step-by-step solution

Understand the structure of the Pistil

The pistil, which is the female reproductive organ in flowers, includes the ovary, style, and stigma.

Identify the parts mentioned in the options

In the given alternatives (A) Ovule, (B) Ovary, (C) Style, (D) Anther, and (E) Stigma, identify each part and compare with the components of the pistil already mentioned.

Identify the part not included in the pistil

On comparing, we can identify that the Anther is the part which is not included in the structure of the pisttl.

Key concepts

Flower Anatomy

Flowers are fascinating reproductive structures in plants that aid in reproduction. They come in diverse shapes, sizes, and colors but generally share a common anatomy. Understanding flower anatomy involves knowing the key parts that contribute to the reproductive process. The two main parts of a flower are the reproductive organs and the non-reproductive parts. The reproductive parts are essential for reproduction and include the pistil and stamen.

• Pistil: The female part of the flower that comprises the stigma, style, and ovary.
• Stamen: The male part of the flower that includes the anther and filament.

Each of these components has a crucial role in the flower's ability to reproduce. By identifying these parts, you can better understand how flowers function and differ from each other.

Plant Reproductive Organs

Plant reproductive organs include structures essential for the plant's propagation through reproduction. These organs exist in the form of the pistil and stamen, which are present within flowers.

The Pistil

The pistil is a key female reproductive part. It consists of:

• Stigma: The sticky top where pollen lands.
• Style: The tube-like structure that connects the stigma to the ovary.
• Ovary: The base of the pistil containing ovules, which develop into seeds post fertilization.

The Stamen

The stamen is the male reproductive organ that comprises:

• Anther: Produces pollen, the male gametes.
• Filament: Stalk holding the anther.

An important function of these organs is to ensure pollination and fertilization, leading to seed production and plant proliferation.

Biology

Biology is the study of life and living organisms, an umbrella that covers various subjects like botany, anatomy, and reproductive sciences. In the context of flowers, biology explores how these living structures function and propagate new life.
The study of plant biology, specifically, aims to help us understand processes such as photosynthesis, nutrient uptake, and reproduction. A key part of plant reproduction is the interactions between the reproductive organs such as the pistil and stamen.
Pollination is a crucial biological process where pollen is transferred from the anther to the stigma. This process leads to fertilization and the eventual production of seeds, promoting genetic diversity. Understanding these concepts not only contributes to our knowledge of plants but also enhances agriculture, allowing for improved crop production and sustainability.
