Question

Assertion: Organisms are made up of cells.
Reason: Cells are structural unit of living organisms. A cell keeps its chemical composition steady within its boundary.

Assertion: Specialization of cells is useful for organism.
Reason: It increases the operational efficiency of an organism.


Assertion: The number of cells in a multicellular organism is inversely proportional to size of body.
Reason: All cells of biological world are alive.

Assertion : Living organisms possess specific individuality with the definite shape and size.
Reason : Both living and non living entities resemble each other at the lower level of organisation.

Assertion : It is important that the organisms should have cell.
Reason : A cell keeps its chemical composition steady within its boundary

Assertion: The number of cells in a multicellular organism is inversely proportional to the size of
body.
Reason: All the cells in the biological world are of same size.

Assertion: Cell is an open system.
Reason: Cell receives a number of materials including energy containing nutrients from outside.

Assertion: Smaller cells are usually metabolically active cells.
Reason: Smaller cell nucleocytoplasmic ratio and surface volume ratio is higher

Assertion: Rudolf Virchow modified the hypothesis of cell theory given by Schleiden and Schwann.
Reason : Cell theory says that all cells arise from pre-existing cells.

Assertion: Schleiden and Schwann were the first to observe the cells and to put forward cell theory.
Reason: The cells are always living unit.


Assertion: As per Schwann, cell wall is a unique character of the plant cell.
Reason: Body of plants and animals are composed of cells and products of cells


Assertion: Eukaryotic cells have membrane bound organelles.
Reason: Prokaryotic cells lack membrane bound organelles.

Assertion: Ribosomes are non-membrane bound organelles found in the prokaryotic cells only.
Reason: These are present only in the cytoplasm.


Assertion: Eukaryotic cells have more DNA than prokaryotic cells.
Reason: Eukaryotes are genetically more complex than prokaryote

Assertion: Prokaryotes have a one envelop system.
Reason: There is not even a single membrane that surrounds the prokaryotic cell.
