The model of the cell prepared here is much bigger than the real cell which is microscopic. So its helpful for studying the structures of the real cell.
Option D.
Step-by-step explanation:
The cell is defined to be the structural and functional unit of an organism. The cell contains different organelles that remain covered in one place i.e demarcated by cell membrane. Inside it there are different organelles like nucleus, mitochondria, ribosome, golgi bodies, lysozome etc. The sizes of these organelles are different. All these organelles are microscopic which makes the visualization of these organelles difficult. So making a model with comparative sizes and structures makes the studying easy for them. Thus this model is very helpful.
