What is the role of glucose in photosynthesis
Glucose is the suger made from sunlight for plants.
Answer: To make substances like cellulose and starch
Explanation: During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch. Cellulose is used in building cell walls. =)

What is the main difference between a cell nucleus and a nucleoid? A.
size of the organelle
arrangement of the cytoskeleton
movement of the flagella
presence or absence of a surrounding membrane
Eukaryotic cells have a nucleus, an organelle that houses proteins and RNA. It's regarded as the biggest and most significant cell organelle.What is the difference between a nucleus and a nucleoid?
Prokaryotes include the nucleoid, an irregularly shaped area that houses genetic material. Eukaryotes have a nucleus that houses their genetic material. It is regarded as the biggest and most well-run cell.
The prokaryotes have nucleoid, which houses their genetic material. It is referred to as the compact and well-organized cell.
Therefore, Eukaryotic cells have a nucleus, an organelle that houses proteins and RNA. It's regarded as the biggest and most significant cell organelle.
