Q: A difference between beans and corn during germination is
a. the cotyledons are above ground in the bean plant
b. the corn shoot is hooked to protect it from damage
c. the bean plant cannot germinate until water penetrates the seed coat
d. oxygen is required in the seed before a corn plant can germinate
A?
Yes, a. THe corn scutellum is behind the growing point, and remains where it started.
ok thanks!
To determine the correct answer to this question, let's analyze each statement and eliminate the incorrect options.
a. The cotyledons are above ground in the bean plant: This statement is true. During germination, the cotyledons, which are embryonic leaves, come above ground in the bean plant. The cotyledons provide nutrients to the growing seedling.
b. The corn shoot is hooked to protect it from damage: This statement is not accurate. The corn shoot does not have a specific hook-like structure to protect it from damage. Therefore, we can eliminate option b.
c. The bean plant cannot germinate until water penetrates the seed coat: This statement is true. Bean seeds have a hard seed coat that needs to absorb water and soften before germination can occur. The water penetration is essential for initiating the germination process in beans.
d. Oxygen is required in the seed before a corn plant can germinate: This statement is also true. Like all germinating seeds, corn requires oxygen for proper germination. Oxygen is needed for energy production during respiration, which is essential for seed germination.
Based on our analysis, the correct answer to the question is option d. Oxygen is required in the seed before a corn plant can germinate.
