Answer:

1.There are many similarities between aquatic and terrestrial plants. Both varieties of the plant are green, with leaves, roots and the ability to flower. Land plants are typically taller than wide and have a branched root system.

2.Why do cacti have spines? Spines help cacti to thrive in desert environments by providing multiple functions. They protect the plant from predators, provide shade, help regulate temperature, reduce water loss and even help the plant to spread and reproduce.

By shading the cactus, these spines also help prevent the cactus from losing water through evaporation. So all in all, spines are adaptations that protect and help cacti hide from animals that may want to eat them. They also provide shade for the plant, which keeps them cooler and limits water loss.
