- A. Sugars
- B. Vitamins
- C. Coconut milk
- D. All of the above
Explanation: Cornell botanist F.C. Steward grew a complete carrot plant from a tiny piece of phloem.
Correct answer: All of the above- A. Callus
- B. Totipotent
- C. Clone
- D. None of the above
Explanation: Thus, callus cultures are basically clumps of cells raised due to disorganized proliferation of cells from the segment of plant organs.
Correct answer: Callus- A. Callus
- B. Seedling
- C. Clonal
- D. Somaclonal
Explanation: When cells divide by mitosis two genetically identical, therefore clonal, daughter cells are produced.
Correct answer: Clonal- A. Callous
- B. Seedling
- C. Clonal plant
- D. Adult plant
Explanation: Another advantage of meristem culture is that meristem, unlike other portions of a plant, it is virus free, therefore the plants produced…
Correct answer: Clonal plant- A. Protoplasm
- B. Cytoplasm
- C. Protoplast
- D. Callus
Explanation: They are isolated cells, whose cell wall is withdrawn and are enveloped by plasmalemma.
Correct answer: Protoplast- A. Callus
- B. Seedling
- C. Clonal
- D. Clump of cells
Explanation: The protoplasts regenerate a new cell wall and begin to divide. These clumps of cells can be manipulated to produce somatic embryos.
Correct answer: Clump of cells- A. Callus
- B. Somatic embryo
- C. Clonal plant
- D. Adult plant
Explanation: The protoplasts regenerate a new cell wall and begin to divide. These clumps of cells can be manipulated to produce somatic embryos.
Correct answer: Somatic embryo- A. Seeds
- B. Artificial seed
- C. Clonal plant
- D. Clumps of cells
Explanation: Synthetic seeds are artificially encapsulated plant propagation material.
Correct answer: Artificial seed- A. Thermocycler
- B. Biopole
- C. Bioreactors
- D. None of the above
Explanation: Bioreactors are vessels that have been designed and produced to provide an effective environment for enzymes or whole cells to transform…
Correct answer: Bioreactors- A. Corn
- B. Tomato
- C. Mango
- D. Roses
Explanation: It is possible to produce millions of somatic embryos at once in large tanks called bioreactors.
Correct answer: Tomato- A. Callus
- B. Seedling
- C. Clonal
- D. Somaclonal
Explanation: The particle gun, that bombards a callus with DNA coated microscopic metal particles.
Correct answer: Callus- A. Wheat
- B. Canola
- C. Cotton
- D. Rice
Explanation: The large number of QTLs identified suggests that cold tolerance in rice expressed at both germination and booting is quantitatively…
Correct answer: Rice- A. Wheat
- B. Canola
- C. Cotton
- D. Sugarcane
Explanation: Drought tolerant crops includes cereals, rice, sugarcane.
Correct answer: Sugarcane- A. Corn
- B. Canola
- C. Cotton
- D. Sugarcane
Explanation: Herbicide-resistant plants are Wheat, rice, sugar beets, canola.
Correct answer: Canola- A. Mustard
- B. Soya bean
- C. Cotton
- D. Sunflower
Explanation: Soybeans have been developed that mainly produce the monounsaturated fatty acid, oleic acid, a change that may improve human health.
Correct answer: Soya bean- A. Oleic acid
- B. Palmitic acid
- C. Vernolic acid
- D. None of the above
Explanation: These altered plants also produce vernolic acid and ricinoleic acid, derivatives of oleic acid that can be used as hardenes in paints and…
Correct answer: Vernolic acid- A. Mustard
- B. Soybean
- C. Castor bean
- D. Sunflower
Explanation: These altered plants also produce vernolic acid and ricinoleic acid, derivatives of oleic acid that can be used as hardenes in paints and…
Correct answer: Castor bean- A. Mustard
- B. Soybean
- C. Cotton
- D. Sunflower
Explanation: Amino acid contents are improved in Corn, soybean
Correct answer: Soybean- A. Mustard
