Which is an adaptation that plants survive on land apex?

The adaptation that helped plants survive on land are vascular systems.
This means that when plants became vascular plants, they were able to start living on land because the elements of the vascular system helped them take water and nutrients from the soil, and in return emit oxygen into the atmosphere around them.

That is true tge cactus as a structural adaptation to its envirinment has it leaves reduced to spines. but this doesnt mean it cant produce food it produces food because of the presence of chlorophyll in its stem
