Plant Propagation Techniques

591 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.

B Correct answer
Explanation

Tissue culture allows for the production of genetically identical copies of plants from a single parent plant, enabling the rapid propagation of plants with desirable traits and the production of disease-free plants.

Multiple choice

What is the term used to describe the practice of growing crops in a controlled environment, often using artificial lighting and hydroponic systems?

  1. Aquaculture

  2. Aeroponics

  3. Hydroponics

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

Hydroponics is the practice of growing crops in a controlled environment, often using artificial lighting and hydroponic systems, where plants are grown in nutrient-rich water solutions without soil.

Multiple choice

The process of formation of new roots from existing roots is known as:

  1. Rhizogenesis

  2. Caulogenesis

  3. Phyllotaxis

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

Rhizogenesis is the process by which new roots are formed from existing roots, enabling the plant to expand its root system.

Multiple choice

The process of formation of new shoots from existing shoots is known as:

  1. Caulogenesis

  2. Rhizogenesis

  3. Phyllotaxis

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

Caulogenesis is the process by which new shoots are formed from existing shoots, enabling the plant to produce branches and increase its photosynthetic capacity.

Multiple choice

What is the process of growing cells in a controlled environment outside of an organism called?

  1. Cell Culture

  2. Tissue Engineering

  3. Genetic Engineering

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

Cell culture is the process of growing cells in a controlled environment outside of an organism.

Multiple choice

What is the best time to apply mulch in the garden?

  1. Spring

  2. Summer

  3. Fall

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

Mulch should be applied in the spring or fall, when the soil is cool and moist. This will help to prevent weeds from germinating and will also help to conserve soil moisture.
