Practice Test Questions with Complete
Solutions
What is the primary goal of plant biotechnology?
✔✔To improve plant characteristics such as yield, pest resistance, and drought tolerance.
What is the role of genes in genetically modified (GM) crops?
✔✔Genes control the traits of plants, and modifying these genes can enhance plant performance.
What is the significance of the Bacillus thuringiensis (Bt) gene in crops?
✔✔It provides resistance to specific insect pests by producing a protein toxic to the pests.
What is a common method used for introducing new genes into plant cells?
✔✔Agrobacterium-mediated transformation.
What does the term "marker gene" refer to in plant biotechnology?
✔✔A gene used to identify successfully transformed cells by providing a selectable trait.
1
,What is the purpose of CRISPR-Cas9 technology in plant genetic engineering?
✔✔To edit the DNA of plants with high precision for desired traits.
What is the primary function of the photosynthesis process in plants?
✔✔To convert light energy into chemical energy, producing glucose and oxygen.
What is the significance of transgenic plants in agriculture?
✔✔They have been genetically modified to possess traits such as pest resistance or improved
nutritional content.
What is an advantage of using genetically modified crops in farming?
✔✔Increased crop yield and reduced reliance on chemical pesticides.
What is the purpose of the "herbicide resistance" trait in genetically modified crops?
✔✔To allow crops to survive herbicide treatment while weeds are controlled.
How does genetic modification help in improving drought tolerance in crops?
2
, ✔✔By altering genes related to water retention or stress resistance, making plants more resilient
under drought conditions.
What is the role of plant hormones in plant growth?
✔✔They regulate processes such as growth, flowering, and fruit development.
What is the function of the chloroplast in plant cells?
✔✔Chloroplasts are responsible for photosynthesis, converting light energy into chemical
energy.
What is the role of the gene "Cry" in Bt crops?
✔✔The Cry gene encodes a protein toxic to specific insect larvae, providing pest resistance.
What is the main concern surrounding the use of genetically modified organisms (GMOs) in
agriculture?
✔✔Potential environmental impacts and concerns about food safety.
What is the purpose of genetic screening in plant breeding?
