Problem 113 - Objective Biology for NEET

Question

Select the incorrect matching: (a) Ornamental - Tulip,gloriosa, lupin, sweet pea, petunia (b) Medicine Muliathi, belladonna, aloe \(\begin{array}{ll}\text { (c) Fodder } & \- & \text { Sesbania, trifolium }\end{array}\) \(\begin{array}{ll}\text { (d) Edible oil }- & \text { Soyabean, groundnut, colchicine }\end{array}\)

Step-by-Step Solution

Answer

Option d is the incorrect matching. While Soyabean and groundnut are used for edible oil, colchicine is used in medicine.

Step 1: Analyze Option a

The first option lists Tulip, gloriosa, lupin, sweet pea, and petunia as ornamental plants. A quick check of each plant confirms they are all used for ornamental purposes, thus this selection is correct.

Step 2: Analyze Option b

The second option categorizes Muliathi, belladonna, and aloe as medicinal plants. An analysis of these plants confirms they all have medicinal properties and uses. Therefore, this is not the incorrect matching.

Step 3: Analyze Option c

The third option states that Sesbania and Trifolium are fodder plants. Looking at these plants shows they are indeed used as fodder. Therefore, this option is not the incorrect matching.

Step 4: Analyze Option d

The final option d lists Soyabean, groundnut, and colchicine as plants used for edible oil. A review of these plants shows that while Soyabean and groundnut are indeed used for edible oil, colchicine is not. It is used in medicine instead, specifically in the treatment of gout. Therefore, this is the incorrect matching.

Key Concepts

Ornamental Plants

Ornamental plants, such as tulips, gloriosa, lupin, sweet pea, and petunia, are cultivated primarily for their aesthetic value and ability to enhance the beauty of any environment. These plants are much more than just decorative; they contribute to a positive ambiance and well-being by improving air quality and reducing stress.

Importance in Landscaping

Ornamental plants are fundamental in landscaping and gardening, serving diverse roles—from being the centerpiece in a garden to providing borders and groundcover. Their variety in size, shape, color, and scent allows for creative design and personal expression in green spaces.

Environmental Benefits

Beyond beauty, they play an ecological role by supporting local wildlife, such as birds and pollinators, contributing to biodiversity.

Medicinal Plants

Medicinal plants like Muliathi, belladonna, and aloe have been recognized for their health benefits and therapeutic properties for centuries. They are the cornerstone of traditional medicine and play a crucial role in modern pharmacology.

Natural Remedies

These plants contain natural compounds that are extracted and utilized to treat various ailments. For instance, aloe is known for its soothing effect on the skin and is widely used in burn treatment and skincare products.

Active Compounds

The active compounds in medicinal plants, such as alkaloids and flavonoids, are scientifically studied for their potential in drug development, emphasizing the value of plant-based medicine in healthcare.

Fodder Plants

Fodder plants such as Sesbania and Trifolium are cultivated primarily for animal feed. These plants are important for sustaining livestock, which, in turn, support human food supplies and agriculture.

Nutritional Value

Fodder plants are evaluated for their nutritional content, digestibility, and palatability. Proper fodder contributes to the health of livestock and the quality of products such as milk, meat, and leather that they provide.

Sustainable Agriculture

Integrating fodder plants in crop rotation and agricultural practices contributes to soil fertility and reduces reliance on synthetic feeds and fertilizers, aligning with sustainable agriculture principles.

Edible Oil Plants

Edible oil plants like soybean and groundnut are known for the high oil content in their seeds, which is extracted and refined to produce cooking oil. These oils are high in nutritional value and are a staple in kitchens around the world.

Health Benefits

Edible oils can be high in essential fatty acids, such as omega-3 and omega-6, and provide energy and support cell growth. Choosing oils with a healthy fat composition is important for maintaining a balanced diet.

Diverse Uses

Beyond cooking, edible oils from plants serve various industrial purposes, including the production of biofuels, cosmetics, and pharmaceuticals, showcasing their versatile applications.
