Answer:
Step 1
The plant takes in carbon dioxide in the atmosphere through the stomata on its leaves. It is worth noting that there are some stomata on the stems as well.
Step 2
Water gets into the plant mainly through the roots and finds its way to the leaves, where photosynthesis occurs. Plant roots are specially designed to draw water from the ground and transport it to the plant leaves through the stem.
Step 3
Chlorophyll, the green coloring matter of the leaf, traps the energy from sunlight as it shines on the leaf. It is worth noting that it is chlorophyll that gives the leaf its green color.
Step 4
The solar energy is used to break water down into hydrogen and oxygen. Then hydrogen is combined with carbon dioxide to make sugar, which is food for the plant. Oxygen is released as a byproduct through the stomata.
Chemical reactions occur with the help of protons from the water molecules and electrons from the chlorophyll molecules to produce Adenosine Triphosphate (ATP). ATP provides energy for cellular reactions and Nicotinamide Adenine Dinucleotide Diphosphate (NADP), which is integral in plant metabolism.

Answer:
Evaporation and Transpiration
Explanation:
Evaporation is the process in which water from bodies of water vaporizes and enters the atmosphere while transpiration is the process in which water from plants evaporates into the atmosphere.
Answer:
Antibiotics cannot kill viruses because bacteria and viruses have different mechanisms and machinery to survive and replicate. The antibiotic has no “target” to attack in a virus.
