Aim- To prepare a temporary slide of onion peel and study the structure of the
plant cell.
Introduction of Cell- Cell is a fundamental unit of structure and function of
living organisms. Cell consists of a cell membrane enclosing a mass of protoplasm.
They cells are self- contained autonomous unit. The activities of cells are
integrated for survival of organism, they independently carry out fundamental
functions such as nutrition, respiration, growth, reproduction and self-regulation.
Prokaryotic Cells lack proper membrane bound nucleus and other membrane
bound cell organelles.
Eukaryotic Cells have membrane bound organelles and proper well defined
nucleus bounded by nuclear membrane.
Examples: plant and animals, fungi
Protoplasm is differentiated into cytoplasm and nucleus. Plant cell possesses cell
wall, central vacuole and photosynthetic organelles chloroplasts.
Answer the following questions on the basis of your observations:
Q.1 Write the procedure of the experiment.
Q.2 Write the materials required for this experiment.
Q.3 What conclusion have you drawn from the experiment?
