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.

What is the process by which plants produce new cells?

  1. Cell division

  2. Cell growth

  3. Cell differentiation

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

Cell division is the process by which plants produce new cells. It occurs when a cell divides into two or more daughter cells. Cell division is essential for growth, development, and repair.

Multiple choice

Which growing method is commonly used for tomatoes to maximize yield and quality?

  1. Hydroponics

  2. Aeroponics

  3. Aquaponics

  4. Traditional soil cultivation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Hydroponics is a growing method where tomatoes are cultivated in a nutrient-rich water solution without soil. This method allows for precise control over nutrient levels, resulting in higher yields and improved fruit quality.

Multiple choice

What is the process of pinching the growing tips of a plant to encourage branching called?

  1. Pinching

  2. Pruning

  3. Topping

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

Pinching is the process of removing the growing tips of a plant to encourage branching and a more compact growth habit.

Multiple choice

What is the process of dividing a plant into multiple smaller plants called?

  1. Propagation

  2. Division

  3. Transplanting

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

Division is the process of dividing a plant into multiple smaller plants, each capable of growing independently.

Multiple choice

What is the process of supporting a plant with a stake or trellis called?

  1. Staking

  2. Trellising

  3. Caging

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

Staking is the process of supporting a plant with a stake to keep it upright and prevent it from falling over.

Multiple choice

What is the term used for the cultivation of aquatic plants in aquaculture systems?

  1. Aquaponics

  2. Hydroponics

  3. Mariculture

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

Aquaponics is a sustainable farming system that combines aquaculture (fish farming) with hydroponics (plant cultivation in water) to create a symbiotic relationship between the two.

Multiple choice

Which aquaculture technique involves the integration of fish farming with the cultivation of plants, often in a symbiotic relationship?

  1. Aquaponics

  2. Hydroponics

  3. Mariculture

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

Aquaponics combines aquaculture and hydroponics, where the waste from fish farming provides nutrients for plant growth, and the plants help filter and clean the water for the fish.

Multiple choice

What is the primary method used for propagating mango trees?

  1. Grafting

  2. Air layering

  3. Stem cuttings

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

Grafting is the primary method used for propagating mango trees, as it allows for the combination of desirable traits from different varieties and ensures consistent fruit quality.

Multiple choice

Which of the following is an example of a plant species that has been successfully conserved through ex-situ methods?

  1. Cycad

  2. Orchid

  3. Rose

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

Cycad is an example of a plant species that has been successfully conserved through ex-situ methods, such as seed banks and botanical gardens.

Multiple choice

What is the primary method of banana propagation?

  1. Seeds

  2. Cuttings

  3. Grafting

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

Bananas are typically propagated through vegetative cuttings, where a section of the rhizome or sucker is planted to produce a new plant. This method allows for the preservation of desirable traits and rapid multiplication of plants.

Multiple choice

What is the process of supporting climbing vegetables, such as tomatoes and cucumbers, called?

  1. Staking

  2. Trellising

  3. Caging

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Staking, trellising, and caging are all methods used to support climbing vegetables and provide them with a structure to grow on.

Multiple choice

What is the process of thinning out seedlings to ensure proper spacing and growth called?

  1. Transplanting

  2. Thinning

  3. Pruning

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

Thinning is the process of removing excess seedlings from a planting area to ensure proper spacing and growth, allowing the remaining plants to develop and produce a higher yield.

Multiple choice

Which of the following is NOT a common type of vegetable grafting technique?

  1. Splice grafting

  2. Whip grafting

  3. Cleft grafting

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

Budding is not a common type of vegetable grafting technique, as it is more commonly used for fruit trees and shrubs.

Multiple choice

What is the term for the process of growing a tissue construct in a bioreactor?

  1. Tissue culture

  2. Tissue engineering

  3. Bioreactor culture

  4. In vitro culture
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Bioreactor culture is the process of growing a tissue construct in a controlled environment using a bioreactor.

Multiple choice

Which technique involves directly converting one cell type into another without going through a pluripotent state?

  1. Transdifferentiation

  2. Somatic Cell Nuclear Transfer (SCNT)

  3. Induced Pluripotent Stem Cell (iPSC) Generation

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

Transdifferentiation is the process by which one cell type directly converts into another cell type without going through a pluripotent state.
