Question

Family Solanaceae and Convolvulaceae belongs to the order (a) Poales (b) Polymoniales (c) Diptera (d) Dicot

Short answer

None of the options listed in the question is correct. Both the Solanaceae and Convolvulaceae families belong to the Solanales order.

Step-by-step solution

Understand the taxonomical hierarchy

The first step is always to know the taxonomical hierarchy and its order: Kingdom, Phylum, Class, Order, Family, Genus, Species. In this case, the Family is Solanaceae and Convolvulaceae.

Identify the Order for the given Families

Next, we need to identify the Order to which these families belong. Both Solanaceae and Convolvulaceae belongs to the order of Solanales. This information can usually be found in textbooks or reliable internet sources.

Match the Order to the options provided

Finally, match the identified Order 'Solanales' to the options provided in the question. Since Solanales isn't listed in the options, there must be an error in the question or the options given are incorrect.

Key concepts

Order Solanales

Order Solanales is part of the taxonomical hierarchy used to classify plants scientifically. This order falls under the class of Magnoliopsida and is part of the angiosperms, which are flowering plants. Solanales was first established based on molecular phylogenetic studies, which help in understanding the evolutionary relationships amongst various plants.

Two well-known families that belong to this order are Solanaceae and Convolvulaceae. This grouping is supported by plant features such as similar floral structures and genetic makeup. One key aspect of biological classification is ensuring groups genuinely reflect homogenous characteristics and evolutionary history.

Family Solanaceae

The Family Solanaceae, often referred to as the "nightshade family," includes a diverse range of plants. This family contains both ornamental plants and major agricultural crops.

Key Characteristics of Solanaceae:

• Many plants in this family have alkaloids, which can be toxic but also have medicinal properties.
• Typical flowers are often funnel-shaped, featuring five petals.
• The fruits generally present as berries or capsules.

If you've ever eaten potatoes, tomatoes, or eggplants, you've experienced plants from this family. These plants are crucial in human diets across the world. However, it's worth noting that some members, like belladonna, are toxic.

Family Convolvulaceae

Family Convolvulaceae is commonly known as the "bindweed" or "morning glory" family. This family mostly consists of herbaceous plants, though some are shrubs or trees.

Noteworthy Features:

• These plants usually have twining (climbing) stems, often used in decorative gardening.
• The flowers frequently appear funnel-shaped and can be quite colorful, ranging from pinks to purples and blues.
• They produce dry fruit called capsules, which contain seeds.

Members of this family, like the sweet potato, are not only beautiful but also provide nutritional benefits. The variety and adaptability of Convolvulaceae make it an interesting subject of study in plant taxonomy and ecology.
