Answer: An Organ System
Explanation: Vascular plants have two distinct organ systems: a shoot system, and a root system. The shoot system generally grows above ground, where it absorbs the light needed for photosynthesis. The root system, which supports the plants and absorbs water and minerals, is usually underground.
Answer: The correct answer is- Converts solar energy to chemical energy.
Photosynthesis is a process of formation of food by green plants and algae using CO₂ and H₂O in the presence of sunlight. In this process, energy from sunlight is absorbed by chlorophyll ( green pigment present in the chloroplast) and it is converted into chemical energy in the form of ATP and NADPH. This is further utilized in the formation of food that is a carboydrate ( glucose).
I think the answer is Specialized cells!
Answer: If enough evidence accumulates to support a hypothesis, it moves to the next step — known as a theory — in the scientific method and becomes accepted as a valid explanation of a phenomenon.
