Plant Propagation Techniques

660 Questions

Plant propagation techniques cover both natural and artificial methods of cultivating plants, including micropropagation, tissue culture, and layering. These botanical concepts evaluate how desirable characteristics are multiplied and transferred into new plants. Questions on this topic routinely feature in the biology segment of various state and central competitive exams.

D Correct answer
Explanation

Option D is a testable hypothesis: 'This plant will grow best in sunlight.' It makes a specific prediction that can be tested by comparing plant growth in different light conditions. Options A, B, and C are opinions or statements, not testable predictions.

Multiple choice botany reproduction in flowering plants common modes of vegetative propagation plant breeding for food production tissue culture

Stem cuttings are commonly used for propagation in 

  1. Rubber

  2. Mangoes

  3. Sugarcane

  4. Jasmine
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Vegetative reproduction is a type of asexual reproduction in which new plants are formed from the vegetative parts like, tubers, runners, suckers, rhizomes etc. Some of the plants can be propagated by the means of cutting. The part which is cut is allowed to grow into a new plant. Stem cutting which can be referred as the cane cuttings are used in the case of sugarcane. 

So, the correct answer is option C.

Multiple choice

What is the term used to describe the ability of a pathogen to overcome plant resistance?

  1. Avirulence

  2. Virulence

  3. Pathogenicity

  4. Aggressiveness
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Virulence refers to the ability of a pathogen to overcome plant resistance and cause disease. Avirulence is the opposite of virulence, and it refers to the inability of a pathogen to cause disease in a resistant plant.

Multiple choice

Which of the following is NOT a common method of disease management in plants?

  1. Cultural practices

  2. Chemical control

  3. Biological control

  4. Genetic engineering
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Genetic engineering is not a common method of disease management in plants. Cultural practices, chemical control, and biological control are all common methods of disease management.

Multiple choice

  1. Infection

  2. Colonization

  3. Reproduction

  4. Dissemination
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Infection refers to the process by which a pathogen enters a plant and establishes itself. Colonization is the process by which a pathogen multiplies and spreads within a plant. Reproduction is the process by which a pathogen produces new offspring. Dissemination is the process by which a pathogen is spread from one plant to another.

Multiple choice

  1. Infection

  2. Colonization

  3. Reproduction

  4. Dissemination
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Dissemination refers to the process by which a pathogen spreads from one plant to another. Infection is the process by which a pathogen enters a plant and establishes itself. Colonization is the process by which a pathogen multiplies and spreads within a plant. Reproduction is the process by which a pathogen produces new offspring.

Multiple choice

What is the term used to describe the ability of a plant to resist infection by a pathogen?

  1. Resistance

  2. Tolerance

  3. Immunity

  4. Susceptibility
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Resistance refers to the ability of a plant to resist infection by a pathogen. Tolerance is the ability of a plant to tolerate the presence of a pathogen without showing symptoms of disease. Immunity is the complete resistance of a plant to a pathogen. Susceptibility is the inability of a plant to resist infection and colonization by a pathogen.
