The correct answer is 1 and 3 only.

  • Vegetative propagation
    • It is an asexual method of plant reproduction that occurs in its leaves, roots and stem.
    • It is often used when the crop plants either do not produce seeds or when the seeds produced are not viable or are of long dormancy.
  • Clonal propagation
    • It is the process of asexual reproduction by multiplication of genetically identical copies of individual plants.
    • It occurs by apomixis (seed development without meiosis and fertilization) and/or vegetative reproduction (regeneration of new plants from vegetative parts).
  • The widespread use of vegetative propagation results in the spread of viruses through propagules such as cuttings, tubers, runners and bulbs. A plant once systemically infected with a virus usually remains infected for its lifetime.
  • Vegetative propagation can be practised most of the year.

Read the following passage and answer the item that follows. Your answers to this item should be based on the passage only. Many farmers use synthetic pesticides to kill infesting insects. The consumption of pesticides in some of the developed countries is touching 3000 grams/hectare. Unfortunately, there are reports that these compounds possess inherent toxicities that endanger the health of the farm operators, consumers and the environment. Synthetic pesticides are generally persistent in environment. Entering in food chain they destroy the microbial diversity and cause ecological imbalance. Their indiscriminate use has resulted in development of resistance among insects to insecticides, upsetting of balance in nature and resources of treated populations. Natural pest control using the botanical pesticides is safer to the user and the environment because they break down into harmless compounds within hours or days in the presence of sunlight. Plants with pesticidal properties have been in nature for millions of years without any ill or adverse effects on the ecosystem. They are easily decomposed by many microbes common in most soils. They help in the maintenance of biological diversity of predators and human health hazards. Botanical pesticides formulated from plants are biodegradable and their use in crop protection is a practical sustainable alternative. Which of the following statements is/are correct regarding biopesticides? 1. They are not hazardous to human health. 2. They are persistent in environment. 3. They are essential to maintain the biodiversity of any ecosystem. Select the correct answer using the code given below.
