What is the function of the lens in a seed?
Understand the Problem
The question asks about the function of the 'lens' (or lenticel) in a seed. It presents four options, and we need to identify which one accurately describes the lens's role.
Answer
The lens regulates water uptake during seed germination.
The lens in a seed primarily regulates water uptake during germination. It acts as the main entry point for water and influences the rate at which the seed absorbs water, which is crucial for successful germination and seedling development.
Answer for screen readers

More Information
The lens is also known as the micropyle in some species. The lens facilitates the physical dormancy break which is a key factor in germination.
Tips
A common mistake is to confuse the function of the lens with other parts of the seed, such as the seed coat or the embryo. The lens is specifically involved in water regulation.
