how do plants get glucose (sugar)
A
EAT IT
B
MAKE IT
C
STEAL IT
D
SING ABOUT IT
Explanation: 

Detailed explanation-1: -During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

Detailed explanation-2: -Green plants manufacture glucose through a process that requires light, known as photosynthesis. This process takes place in the leaf chloroplasts. Carbon dioxide and water molecules enter a sequence of chemical reactions within the chloroplasts.

Detailed explanation-3: -Plants use glucose for respiration. They break down glucose and the chemical energy thus released is used by the plant for other cellular activities. Glucose is also used to prepare starch and cellulose. It is used to produce oil or fat to store in seeds.

Detailed explanation-4: -Plants take in light from the sun (or through artificial means) through openings in their leaves known as stomata and join together with water from the soil, carbon dioxide from the air and chlorophyll from within the plant, to create sugars in their leaves at sites known as chloroplasts.
