Final answer:
The statement that creeping bentgrass has greater low-temperature hardiness than annual bluegrass is true, indicating its better adaptation to cold climates. Mosses thrive in the Arctic tundra due to their ability to grow well at cold temperatures and without true roots. Grassland plants have adapted to frequent forest fires through characteristics like protective bark or rapid post-fire regeneration.
Step-by-step explanation:
Creeping bentgrass does have greater low-temperature hardiness than annual bluegrass, which is true. This hardiness is an adaptation to cold climates, allowing bentgrass to survive and thrive under lower temperature conditions. Annual bluegrass, on the other hand, is less hardy in the face of cold temperatures, making it more susceptible to damage or death from exposure to low temperatures.
The adaptation of some plant species, like creeping bentgrass, to cold environments includes various mechanisms, such as antifreeze proteins, changes in cell membrane composition, and alterations to other cellular processes that confer greater resilience to freezing.
Mosses grow well in the Arctic tundra because a. They grow better at cold temperatures. Mosses lack true roots and can grow on hard surfaces, which makes tundra conditions suitable for their growth. Mosses can also tolerate low temperatures and have adapted to the cold conditions of the Arctic tundra.
In grasslands, where forest fires are a common occurrence, plants have adapted to these conditions in various ways. For example, some plants may have developed protective structures, like thick bark, to withstand fires, while others may rely on rapid post-fire regeneration strategies.
