Students observed cells under the microscope. They observed that the cells had a cell wall, cell membrane, nucleus, and many chloroplasts.
Which observation helps students identify the type of cell observed?
A. The presence of a nucleus means the cells are from a plant.
B. The presence of a cell membrane means that the cells are from an animal.
C. The presence of chloroplasts means that the cells are from a plant.
D. The presence of a cell wall means that the cells are from an animal.
Answers
Answer:
c
Explanation:
Since chloroplasts are only found in plant cell not in animal cell.
Hope you understand
Answer:
C. The presence of chloroplasts means that the cells are from a plant .
This statement proves that chloroplasts are present only in plants and hence the cells the students have found must have been plant cells . Plants use the green colour pigment called chlorophyll which are present in their chloroplasts to absorb sun light and convert it into chemical energy . This process is called as photosynthesis and is one of the key roles done by plants . Chloroplasts will be very important in the doing of photosynthesis , because without it plants wont be able to absorb solar energy , convert it into chemical energy and then into food . And since we humans dont need to absorb solar energy and get it ( solar energy ) directly through the heat transfer method called - radiation , we dont have chloroplasts . Therefore , the statement - C .The presence of chloroplasts means that the cells are from a plant , will make the students identify the cell type , which is a plant cell .
