Question

Q1) Select whether the statement is true or false:

f) The electrical gradient across the plasma membrane is caused by ATP moving into and out of cells.

g) Both eukaryotic cells and prokaryotic cells have a plasma membrane.

h) Dissecting microscopes are designed to have a magnified and clear view of tissue structure as well as the anatomy of the whole organism.

j) Endocytosis is the process by which a cell expels material into the extracellular fluid.

Answer 1

f) The electrical gradient across the plasma membrane is caused by ATP moving into and out of cells.

This statement is false as electrical gradient is not created by the movement of ATP into and out of the cells. It is created by the ions present inside and outside the cells.

g) Both eukaryotic cells and prokaryotic cells have a plasma membrane. True

This is correct as all cells have plasma membrane.

h) Dissecting microscopes are designed to have a magnified and clear view of tissue structure as well as the anatomy of the whole organism. True

These microscopes provide three dimensional image of an object. They provide clear view of structure and anatomy of an object.

j)Endocytosis is the process by which a cell expels material into the extracellular fluid.

This statement is false. Endocytosis is not the process of removal of the extracellular fluid. It is a process of intake of extracellular fluid.
