Identify and describe the function/purpose of the following specimens: A - Dry hide of sheep, B - Hoof of a sheep, C - Ear of a sheep, D - Tail of a sheep, E - Pepper plant showing leaf curl disease,

Here are the detailed notes on the specimens:

• A - Dry hide of sheep: This is the skin of a sheep, which, after processing, is used to produce leather. It is a valuable byproduct of sheep farming.
• B - Hoof of a sheep: The hard, protective covering on the foot of a sheep. It supports the animal's weight and requires regular trimming to prevent lameness and infections.
• C - Ear of a sheep: The external organ of hearing. Sheep ears are often used for identification purposes, such as attaching ear tags or making notches.
• D - Tail of a sheep: The caudal appendage. In many sheep breeds, the tail is docked (removed or shortened) shortly after birth to improve hygiene and prevent flystrike.
• E - Pepper plant showing leaf curl disease: This is a viral disease, often caused by Pepper leaf curl virus, transmitted by whiteflies. Symptoms include severe upward curling and distortion of leaves, stunting of the plant, and reduced fruit yield.
• F - Cassava plant showing mosaic disease: A widespread viral disease, primarily Cassava mosaic virus, transmitted by whiteflies. It causes characteristic yellow and green mottling on leaves, leaf distortion, and significant reduction in tuber yield.
• G - Cassava starch: A carbohydrate extracted from cassava tubers. It is widely used as a thickener in food products, and in industrial applications like textiles, paper, and adhesives.
• H - Mouldy maize grain: Maize grain contaminated by various fungi (moulds). This indicates poor storage conditions and can lead to the production of mycotoxins (e.g., aflatoxins), which are harmful to humans and livestock.
• J - Maize grain: The edible kernel of the maize (corn) plant. It is a major staple food crop globally and a primary source of animal feed, rich in carbohydrates.
• K - Onion bulb showing color rot: This typically refers to a fungal disease, such as anthracnose or other storage rots. Symptoms include discolored, sunken lesions on the bulb, leading to softening and decay, often occurring during storage.
• M - Sweet potato: A starchy, sweet-tasting root vegetable (storage root). It is a significant food crop, rich in carbohydrates, dietary fiber, and vitamins, particularly vitamin A.
• N - Folic acid: Also known as vitamin B9, it is essential for cell division and growth. In agriculture, it is often supplemented in animal feed to support reproductive health and overall growth.
• P - Cassava tuber: The large, starchy underground storage root of the cassava plant. It is a vital staple food in tropical regions but requires proper processing (e.g., peeling, grating, cooking) to remove toxic cyanogenic compounds.
• Q - Yam tuber: The starchy, edible underground stem (tuber) of the yam plant. It is a major staple food crop, especially in West Africa, providing a significant source of carbohydrates.
