Answer:
When plants evolved to survive on land, they faced a number of challenges and risks that they had to overcome in order to thrive in this new environment. Some of these challenges and risks include:
Lack of water: Plants need water to survive, but on land, water is not always readily available. Plants had to evolve specialized structures like roots, stems, and leaves to collect water and transport it throughout the plant.
Exposure to the sun: On land, plants are exposed to high levels of sunlight, which can be harmful if not managed properly. Plants had to evolve mechanisms like waxy coatings and pigments to protect themselves from the harmful effects of UV radiation.
Support: In the water, plants can rely on buoyancy to support their weight, but on land, they need to be able to support themselves. Plants had to develop structures like stems and woody trunks to provide support and stability.
Reproduction: In the water, plants can rely on water currents to disperse their seeds, but on land, they need to be able to spread their seeds without the aid of water. Plants had to evolve structures like flowers and fruits to attract pollinators and seed dispersers.
Herbivores: On land, plants are exposed to a variety of herbivores that can eat them. Plants had to evolve defenses like thorns, spines, and chemical toxins to protect themselves from being eaten.
Overall, the ability of plants to overcome these challenges and risks has allowed them to colonize a wide range of terrestrial environments and to become an essential part of the Earth's ecosystems.
