Topic: Flower Structure and Parts
Q1. Which part of a flower is mainly responsible for producing pollen grains?
- Stigma
- Anther
- Ovary
- Sepal
Q2.The filament and anther together form the:
- Pistil
- Stamen
- Ovule
- Petal
Q3. Which part of the pistil receives pollen grains?
- Ovary
- Style
- Stigma
- Ovule
Q4. The ovules are present inside the:
- Anther
- Ovary
- Filament
- Petal
Q5. Which part of a flower usually attracts insects and other pollinating agents because of its colour and appearance?
- Petal
- Ovule
- Anther
- Style
Q6. Which sequence correctly represents the parts of the pistil from the top to the base?
- Ovary --> Style --> Stigma
- Stigma --> Style --> Ovary
- Style --> Ovary --> Stigma
- Stigma --> Ovary --> Style
Short questions
Q1. Name the two main reproductive structures of a flower. What is the main function of each?
Q2. What is a stamen? Name its two main parts and state the function of each.
Q3. What is a pistil? Name its three main parts.
Q4. Differentiate between the functions of the stigma and ovary in a flower.
Q5. While arranging flowers in a vase, a student notices colourful petals surrounding the central structures of the flower.
Why are petals important to many flowering plants?
Q6. During a biology activity, students carefully observe a hibiscus flower and identify its anther, filament, stigma, style, and ovary.
Why is observing an actual flower useful for understanding its reproductive structure?
Q1. Describe the structure of a typical flower. Explain the roles of the sepals, petals, stamens, and pistil in the flower.
Q2. Explain the structure of the stamen and pistil in detail. Include the functions of the anther, filament, stigma, style, ovary, and ovules.
Q3.Draw a neat, labelled diagram of a typical flower and label the following parts:
Sepal
Petal
Anther
Filament
Stigma
Style
Ovary
Ovule
Also write the reproductive significance of any four labelled parts.
Q1. A student picks up a hibiscus flower during a school biology activity and notices a long structure in the centre ending in a sticky surface.
a) Which reproductive structure is being observed?
b) Name the parts represented by the long portion and its sticky upper surface.
Q2. A gardener observes that insects frequently visit the colourful flowers in his garden.
a) Which flower part is mainly responsible for attracting many insects?
b) How can these visits be useful to the reproductive process of flowering plants?
Q3. Three students describe different parts of a flower:
Student A: “My part produces pollen grains.”
Student B: “My part receives pollen grains.”
Student C: “My part contains ovules.”
Identify the flower part being described by each student.
