Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Jared observes a cell in biology lab with the light microscope. The cell has the following structures:nucleus, cell wall, and chloroplast. Identify the type of cell that Jared is observing.
A
animal
B
plant
C
fungus
D
bacteria
Explanation: 

Detailed explanation-1: -The presence of the organelles proves that the cell is eukaryotic. The cell is a plant because of the cell wall.

Detailed explanation-2: -Since the cell has a large central vacuole, it must be a plant cell.

Detailed explanation-3: -Thus, light microscopes allow one to visualize cells and their larger components such as nuclei, nucleoli, secretory granules, lysosomes, and large mitochondria. The electron microscope is necessary to see smaller organelles like ribosomes, macromolecular assemblies, and macromolecules.

Detailed explanation-4: -An eukaryotic organelle that can easily be seen with the light microscope is the. endoplasmic reticulum.

Detailed explanation-5: -Chloroplasts. Plants are autotrophs; they produce energy from sunlight through the process of photosynthesis, for which they use cell organelles called chloroplasts. Animal cells do not have chloroplasts.
