(b) Discuss photorespiration. What is the relationship between photorespiration and photosynthesis?

Answer: Photorespiration is a process that occurs in plants, in which oxygen is consumed and carbon dioxide is produced, leading to the loss of energy and carbon that could otherwise be used for photosynthesis. The process occurs in the light and involves a series of reactions that occur in the chloroplast, peroxisome, and mitochondria.

During photosynthesis, plants take in carbon dioxide and produce oxygen and glucose, using the energy from light to drive the reactions. However, in certain conditions, such as when the temperature is high or when carbon dioxide levels are low, the enzyme RuBisCO, which is responsible for fixing carbon dioxide in the Calvin cycle, can mistakenly bind with oxygen instead of carbon dioxide. This results in the formation of a toxic compound that must be detoxified by a complex set of reactions, collectively called photorespiration.

The relationship between photorespiration and photosynthesis is complex, as they are intertwined processes that compete for the same resources. While photosynthesis produces energy and carbon compounds that can be used for growth and reproduction, photorespiration consumes some of these compounds and dissipates some of the energy that would otherwise be used for photosynthesis.

Overall, photorespiration reduces the efficiency of photosynthesis and limits plant growth, especially in conditions where carbon dioxide is scarce. Understanding the mechanisms of photorespiration is an active area of research, as it could provide insights into how to improve the efficiency of photosynthesis and increase crop yields.

8. (a) Enlist the seed spices grown in India. Briefly discuss the cultivation and postharvest management practices for coriander and cumin.

Answer: India is a land of spices and has a long history of the spice cultivation. Seed spices are an important group of spices grown in India. Some of the commonly grown seed spices in India are coriander, cumin, fennel, fenugreek, mustard, sesame, poppy, and ajwain.

Coriander and cumin are two of the most important seed spices grown in India. Let's discuss the cultivation and postharvest management practices for these two spices in brief:

Coriander:

Coriander is an annual herb that belongs to the Apiaceae family. It is grown extensively in India, particularly in the states of Rajasthan, Gujarat, Madhya Pradesh, Andhra Pradesh, and Karnataka. Coriander requires a cool and dry climate and grows well in well-drained soils. The seeds are sown in rows, and the seedlings are thinned to a distance of 10-15 cm. The crop requires regular irrigation and is usually ready for harvest in 100-120 days.

Postharvest management: After harvest, the coriander seeds are sun-dried to a moisture content of 8-10%. The dried seeds are then cleaned and packed in gunny bags for storage. Proper storage conditions, including low temperature and low humidity, are necessary to maintain the quality of coriander seeds.

Cumin:

Cumin is an annual herb that belongs to the Apiaceae family. It is grown extensively in India, particularly in the states of Gujarat, Rajasthan, and Uttar Pradesh. Cumin requires a warm and arid climate and grows well in well-drained soils. The seeds are sown in rows, and the seedlings are thinned to a distance of 10-15 cm. The crop requires regular irrigation and is usually ready for harvest in 120-150 days.

Postharvest management: After harvest, the cumin seeds are sun-dried to a moisture content of 8-10%. The dried seeds are then cleaned and packed in gunny bags for storage. Cumin seeds are sensitive to high temperatures and humidity, and proper storage conditions, including low temperature and low humidity, are necessary to maintain the quality of cumin seeds.

In summary, the cultivation and postharvest management practices for coriander and cumin involve proper soil and climate requirements, regular irrigation, and sun-drying and storage of the seeds at low temperatures and humidity to maintain their quality.

(b) Describe the various methods of pest control with appropriate examples.

Answer: There are several methods of pest control, ranging from chemical to non-chemical methods. Here are some examples:

Chemical pest control: Chemical pesticides are the most common method of pest control. They work by killing or repelling pests with toxic chemicals. Examples of chemical pest control methods include insecticides, fungicides, and herbicides.

Biological pest control: Biological pest control involves using natural predators or parasites to control pest populations. This method is often used in agricultural settings. Examples of biological pest control include using ladybugs to control aphids and using parasitic wasps to control caterpillars.

Cultural pest control: Cultural pest control involves changing the environment to make it less hospitable to pests. For example, crop rotation can help prevent the buildup of pests in the soil.

Mechanical pest control: Mechanical pest control involves physically removing pests from an area. This method is often used in homes and gardens. Examples of mechanical pest control include using sticky traps to catch flies and using nets to keep birds away from crops.

Integrated pest management: Integrated pest management (IPM) is a holistic approach that combines multiple methods of pest control. IPM involves monitoring pest populations, identifying the most effective methods of control, and using a combination of methods to achieve long-term pest control. This approach is often used in agriculture.

It's important to note that some methods of pest control, such as chemical pesticides, can have negative environmental impacts. As such, it's important to choose the most appropriate method of pest control for the situation, taking into account factors such as the type of pest, the environment, and the potential impact of the method on non-target species.

(c) What is food security? Why is it essential? Describe the current food security system in India.

Answer: Food security refers to the condition where all people, at all times, have access to sufficient, safe, and nutritious food to meet their dietary needs and preferences for an active and healthy life. Food security is essential because it is a fundamental human right and is crucial for achieving sustainable development, reducing poverty, and improving the health and well-being of people.

In India, the government has implemented various schemes and policies to address food security. The main components of India's food security system are:

Public Distribution System (PDS): The PDS is a government-run system that provides subsidized food grains to eligible households. The food grains are distributed through a network of fair price shops (FPS) across the country. The PDS is the primary mechanism for ensuring food security for the poor and vulnerable sections of the population.

Mid-day Meal Scheme (MDMS): The MDMS is a school feeding program that provides free cooked meals to children in primary and upper primary schools. The scheme aims to improve the nutritional status of children, increase school enrollment and attendance, and promote social equity.

National Food Security Act (NFSA): The NFSA is a landmark legislation passed in 2013 that aims to provide food and nutritional security to the most vulnerable sections of the population. The act provides for the identification of eligible households and the distribution of subsidized food grains through the PDS.

Integrated Child Development Services (ICDS): The ICDS is a flagship program of the government of India that aims to provide a package of services, including supplementary nutrition, health, and education, to children under six years of age and their mothers.

Despite the various schemes and policies, India continues to face significant challenges in ensuring food security for all. Issues such as inadequate food production, high levels of food waste, poor distribution systems, and rising food prices remain major obstacles to achieving food security. Additionally, the COVID-19 pandemic has further exacerbated food insecurity, particularly among vulnerable sections of the population. The government of India needs to continue to invest in improving the food security system and addressing these challenges to ensure that all citizens have access to safe and nutritious food.
