Correct answer: Vexillary
Fabaceae exhibits vexillary aestivation where the largest petal overlaps the two lateral petals.
Which family shows epipetalous stamens?
- A Fabaceae
- B Solanaceae
- C Liliaceae
- D Brassicaceae
Correct answer: Solanaceae
In Solanaceae, stamens are attached to the petals, a condition known as epipetalous.
Which type of ovary is present in Fabaceae?

Correct answer: Superior ovary
Fabaceae has a superior ovary. The ovary is monocarpellary and unilocular.
The fruit of Fabaceae is typically a:
- A Berry
- B Capsule
- C Legume
- D Drupe
Correct answer: Legume
Fabaceae produces a legume or pod, which splits open along two sutures.
Which family is characterized by actinomorphic flowers with fused petals?
- A Fabaceae
- B Solanaceae
- C Liliaceae
- D Brassicaceae
Correct answer: Solanaceae
Solanaceae flowers are actinomorphic and gamopetalous. The petals are fused forming a tubular corolla.
Which family shows parallel venation in leaves?
- A Fabaceae
- B Solanaceae
- C Liliaceae
- D Brassicaceae
Correct answer: Liliaceae
Liliaceae is a monocot family, and monocots typically show parallel venation.
Which type of root system is found in Fabaceae?
- A Fibrous
- B Tap root
- C Adventitious
- D Prop roots
Correct answer: Tap root
Fabaceae plants generally have a tap root system, often with root nodules for nitrogen fixation.
Which family has a perianth instead of distinct calyx and corolla?
- A Fabaceae
- B Solanaceae
- C Liliaceae
- D Malvaceae
Correct answer: Liliaceae
In Liliaceae, the perianth consists of tepals that are not differentiated into sepals and petals.
Which family is known for having tetradynamous stamens?
- A Amaranthaceae
- B Solanaceae
- C Liliaceae
- D Brassicaceae
Correct answer: Brassicaceae
Brassicaceae shows tetradynamous stamens, but Amaranthaceae, Solanaceae, and Liliaceae do not exhibit this feature.
Which type of placentation is found in Solanaceae?
- A Basal
- B Marginal
- C Axile
- D Parietal
Correct answer: Axile
Solanaceae has axile placentation where ovules are attached to the central axis.
Which family includes plants like pea and gram?
- A Solanaceae
- B Fabaceae
- C Liliaceae
- D Poaceae
Correct answer: Fabaceae
Fabaceae includes economically important plants like pea and gram. These are leguminous plants.
Which family includes plants like potato and tomato?
- A Solanaceae
- B Fabaceae
- C Liliaceae
- D Brassicaceae
Correct answer: Solanaceae
Solanaceae includes important crops like potato and tomato. These plants have characteristic floral structures.
Which family includes onion and garlic?
- A Fabaceae
- B Solanaceae
- C Poaceae
- D Liliaceae
Correct answer: Liliaceae
Liliaceae includes plants like onion and garlic. They have bulbs and parallel venation.
Which type of fruit is common in Solanaceae?
- A Berry or capsule
- B Follicle or achene
- C Drupe or nut
- D Samara or caryopsis
Correct answer: Berry or capsule
Solanaceae produces fruits like berries (tomato) or capsules (Datura). These vary within the family.
Which floral symmetry is observed in Fabaceae?
- A Zygomorphic
- B Actinomorphic
- C Asymmetrical
- D Radial
Correct answer: Zygomorphic
Fabaceae flowers are zygomorphic, meaning they can be divided into two equal halves only along one plane.
Which type of stamens arrangement is found in Fabaceae?
- A Diadelphous
- B Monadelphous
- C Polyadelphous
- D Free
Correct answer: Diadelphous
Fabaceae typically shows diadelphous stamens, where 9 stamens are fused and 1 is free.
Which family shows superior ovary with trilocular condition?
- A Fabaceae
- B Solanaceae
- C Poaceae
- D Liliaceae
Correct answer: Liliaceae
Liliaceae has a superior, trilocular ovary. It contains many ovules arranged in axile placentation.
Which type of venation is seen in Solanaceae leaves?
- A Reticulate
- B Parallel
- C Dichotomous
- D Spiral
Correct answer: Reticulate
Solanaceae is a dicot family, and dicots typically have reticulate venation in leaves.
