Q. What is the primary purpose of pollination in flowering plants?
A.To attract herbivores
B.To facilitate fertilization
C.To enhance photosynthesis
D.To increase seed dispersal
Solution
Pollination is essential for the transfer of pollen from the male anther to the female stigma, enabling fertilization and subsequent seed development.
Correct Answer: B — To facilitate fertilization
Q. What is the significance of mycorrhizal associations in plant reproduction?
A.They enhance seed germination
B.They provide nutrients and water to the plant
C.They increase flower production
D.They prevent pollination
Solution
Mycorrhizal associations improve nutrient and water uptake for plants, which can enhance overall health and reproductive success.
Correct Answer: B — They provide nutrients and water to the plant
Q. What is the term for the process by which seeds are spread away from the parent plant?
A.Germination
B.Pollination
C.Dispersal
D.Fertilization
Solution
Dispersal is the process that allows seeds to be spread away from the parent plant, reducing competition and increasing the chances of successful germination.
Correct Answer: C — Dispersal
Q. What role do fruits play in the reproduction of flowering plants?
A.They provide nutrients to the roots
B.They protect the seeds and aid in their dispersal
C.They enhance photosynthesis
D.They attract herbivores for growth
Solution
Fruits protect developing seeds and often aid in their dispersal by attracting animals that eat the fruit and excrete the seeds elsewhere.
Correct Answer: B — They protect the seeds and aid in their dispersal
Q. Which method of plant reproduction is commonly used in agriculture to produce clones of a desired plant?
A.Sexual reproduction
B.Cross-pollination
C.Asexual reproduction
D.Seed dispersal
Solution
Asexual reproduction, such as cuttings or grafting, allows farmers to produce genetically identical plants with desirable traits.
Correct Answer: C — Asexual reproduction
Q. Which of the following is a benefit of using genetically modified organisms (GMOs) in plant reproduction?
A.Increased genetic diversity
B.Enhanced resistance to pests and diseases
C.Slower growth rates
D.Reduced crop yields
Solution
GMOs can be engineered to have enhanced traits, such as pest resistance, which can lead to higher crop yields and reduced reliance on chemical pesticides.
Correct Answer: B — Enhanced resistance to pests and diseases
Q. Which of the following is a common method of seed dispersal?
A.Wind
B.Photosynthesis
C.Germination
D.Transpiration
Solution
Wind is a common method of seed dispersal, allowing seeds to travel long distances from the parent plant.
