The question is incomplete as it does not have the options which are:
A) roots. B) spores. C) seed pods. D) chlorophyll.
Answer:
A) roots
Explanation:
The vascular plants are evolved from the Bryophytes which are evolved from the algae.
The algae are non-vascular plants and Bryophytes too. The vascular plants developed the vascular tissue to transport the absorbed water and nutrients from the terrestrial surface.
The plants living during the Devonian period possessed the vascular tissue to transport the nutrients but to absorb the nutrients and water, they also possessed the roots.
Thus, Option-A is the correct answer.
Explanation:
Environmental exposure to certain chemicals, ultraviolet radiation, or other external factors.
Answer:
Active Transport: Active transport pumps molecules through the cell membrane against the concentration gradient.
Passive transport, also known as passive diffusion, is a process by which an ion or molecule passes through a cell wall via a concentration gradient, or from an area of high concentration to an area of low concentration.
