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.
Answer:
C
Explanation:
Let's look at the cellular respiration equation
oxygen+glucose--> water + carbon dioxide + ATP
In the process, oxygen is used. We inhale oxygen and use it in cellular respiration. We then create carbon dioxide which is exhaled out. We don't use the carbon dioxide, so it is the waste product.
Therefore, the answer is C. Oxygen is used, and carbon dioxide is released as waste.
