Robert Hooke discovered cells in ______

• Liver cells of human

• Meristematic tissue

• Cork cells

• Bacterial culture

Assertion : Mitochondria and chloroplasts are

semi autonomous organelles.

Reason: They are formed by division of pre-existing

organelles as well as contain DNA but

lack protein synthesizing machinery

• Both assertion and reason are true, and the reason is the correct explanation of the assertion.

• Both assertion and reason are true, but the reason is not the correct explanation of the assertion.

• The assertion is true but the reason is false.

• . Both assertion and reason are false

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.

• Both assertion and reason are true, and the reason is the correct explanation of the assertion.

• Both assertion and reason are true, but the reason is not the correct explanation of the assertion.

• Assertion is true but reason is false.

• Both assertion and reason are false

Identify the cell organelles

• 1- chloroplast, 2- Golgi complex, 3- mitochondria

• 1- chloroplast, 2- RER, 3- SER

• 1- chloroplast, 2- SER, 3- Mesosome

• 1- chloroplast, 2- vacuole 3- SER

8. Find out the false sentence

• Golgi apparatus is involved with the formation of lysosomes

• Nucleus, mitochondria and plastid have DNA; hence they are able to make their own structural proteins

• Mitochondria is said to be the power house of the cell as ATP is generated in them.

• Cytoplasm is called as protoplasm
