Topic: Vegetative Propagation Natural and Artificial
Q1. Vegetative propagation is a type of reproduction in which a new plant develops from:
- Only seeds
- Vegetative parts of a plant
- Pollen grains only
- Fertilised eggs only
Q2. Which of the following is an example of natural vegetative propagation through a stem?
- Potato
- Wheat seed
- Pea seed
- Mustard seed
Q3. Which part of Bryophyllum can give rise to new plants through vegetative propagation?
- Leaf
- Flower
- Fruit
- Pollen grain
Q4. Which technique is commonly used by farmers and gardeners to produce new plants from selected parent plants?
- Vegetative propagation
- Respiration
- Transpiration
- Photosynthesis
Q5. Which of the following is an example of artificial vegetative propagation?
- New plants developing from potato eyes
- New plants developing from leaf buds of Bryophyllum
- Growing a plant by cutting and planting a stem piece
- New plants developing naturally from runners
Q6. Which statement correctly describes one advantage of vegetative propagation?
- It always produces plants with completely different characteristics
- It can help produce new plants quickly from a parent plant with desirable features
- It can occur only in plants that produce flowers
- It always requires fertilisation
Short questions
Q1. What is vegetative propagation? Name any two vegetative parts of a plant that can participate in this process.
Q2. What is natural vegetative propagation? Give one suitable example.
Q3. What is artificial vegetative propagation? Name any two methods used by humans.
Q4. How does a potato tuber help in producing new potato plants? Mention the importance of the small structures present on the tuber.
Q5. A gardener wants to produce several new rose plants from a healthy rose plant in the garden.
Which method of artificial vegetative propagation could the gardener use? Why might this method be useful?
Q6. Farmers and gardeners often want to grow plants that have desirable characteristics such as good-quality fruits or flowers.
Why can artificial vegetative propagation be useful for achieving this purpose?
Q1. Explain natural vegetative propagation through roots, stems, and leaves. Give one suitable plant example for each method.
Q2. Describe the major methods of artificial vegetative propagation used in plants. Explain cutting, layering, and grafting with suitable examples.
Q3. Vegetative propagation is widely used in agriculture, gardening, and horticulture. Explain any four advantages of vegetative propagation. Also mention one limitation or concern associated with producing plants in this way.
Q1. A student notices that small plantlets are growing along the edges of a Bryophyllum leaf.
a) Which type of vegetative propagation is being observed?
b) Which plant part is involved in producing the new plantlets?
Q2. A farmer has a mango plant with fruits of excellent quality. The farmer wants to produce new plants that retain the desirable characteristics of the parent plant rather than depending on seeds.
a) Which broad method of plant propagation would be suitable?
b) Name one artificial technique that could be considered for this purpose.
Q3. Three students observe the following:
Student A: New plants develop from the eyes of a potato.
Student B: A gardener places a stem cutting into suitable soil and a new plant develops.
Student C: A branch of one plant is joined with another plant so that the tissues grow together.
Identify the type of vegetative propagation represented in each case and classify it as natural or artificial.
