Q.

Read the following statements and find out the correct statements.

$\left(a\right)$ The shape of cells may vary with the function they perform.

$\left(b\right)$ The prokaryotic cells lack all membrane-bound organelles.

$\left(c\right)$ Schleiden, a German botanist concluded, based on his studies on plant tissues, that the presence of cell walls is a unique character of the plant cells.

$\left(d\right)$ Based on their studies on plants and animals, Schwann, a British Zoologist, proposed the hypothesis that the bodies of animals and plants are composed of cells and products of cells.

$\left(e\right)$ Schleiden and Schwann modified the hypothesis of Rudolf Virchow and gave the cell theory a final shape.
