Cell Theory, Structure and Function Quiz

Schleiden and Schwann articulated that :

• prokaryotes are more evolved than eukaryotes.

• all organisms are made of cells

• organisms are spontaneously generated.

Why did it take a while for the cell theory to be developed after Robert Hooke first observed cells in 1665?

• most of Robert Hooke's work was lost

• no one believed him

• the work of other scientists such as Van Leewenhoek, Schleiden and Schwann helped to support the concept of cell theory.

• Neither

• the salt molecules from side A will move to side B.

• the salt molecules will not move in either direction.

Based on this image what will happen during OSMOSIS?

• the water molecules will move from side A to side B until they are at equilibrium.
