Prairie grasses grow from the roots and not from the tips.
How does this adaptation help prairie grasses to survive?
a. The grass can grow wider to make the stem more sturdy
b. The grass can take in more carbon dioxide
c. The grass can photosynthesize faster near the root
d. The grass can keep growing if it is eaten by grazing animals
I don't understand the question that well. Can someone explain? I think it might be d.
It is not about what is above ground. Therefore b and c are no good. I suppose a would be possible but suspect that d is correct because indeed those grasses fed buffalo, cattle etc. and spreading out underground so you can pop up here and there is helpful.
So if some of the grass is eaten, the grass will grow back at the root? I think its d then
I am inclined to agree with you.
Thank you.
You are welcome.
The question is asking how the adaptation of growing from the roots instead of the tips helps prairie grasses survive. In order to find the correct answer, let's break down the possible options:
a. The grass can grow wider to make the stem more sturdy: This option is not directly related to the adaptation of growing from the roots. It talks about the stem becoming sturdier, which doesn't necessarily have a direct connection to the adaptation itself. Therefore, we can eliminate this option.
b. The grass can take in more carbon dioxide: While carbon dioxide is an important component for photosynthesis, growing from the roots or tips wouldn't make a significant difference in the grass's ability to obtain carbon dioxide. Therefore, this option is unlikely to be the correct answer.
c. The grass can photosynthesize faster near the root: This option could be a possibility. Growing from the roots allows the grass to maximize the surface area available for photosynthesis, as the majority of the leafy tissue is concentrated near the base. This increased photosynthetic capacity can help the grasses produce more energy and survive better.
d. The grass can keep growing if it is eaten by grazing animals: This option is not directly related to the adaptation of growing from the roots. While it is true that prairie grasses have adaptations to withstand grazing, such as the ability to regrow from the base if eaten, this does not specifically relate to the way they grow from the roots or tips.
Based on the explanations above, option c seems to be the most likely correct answer. Growing from the roots helps prairie grasses photosynthesize faster, which increases their ability to generate energy and ultimately aids in their survival.
