Where does the cell theory state that all cells come from?

a. spontaneous generation
b. genetic engineering
c. other cells
d. evolutions

Plants that adapted to the cooler conditions would survive and rapidly evolve into a  new species.

Explanation:

The plants will react by evolving through natural selection.

The plant species that do not have the genes to adapt to the rapid change in climate would become extinct while those with adaptive genes will survive, reproduce, and contribute rapidly to the development of future generations.

In other words, natural selection selects for individuals with adaptive genes and ensures that such individuals reproduce more and give rise to future generations with the adaptive gene while individuals that are poorly adapted to the change in climate gradually fade off the population.

Hence, the plants that adapted to the cooler conditions would survive and rapidly evolve into new species.
