What kind of cells were discovered in the cork?

Plant cells

5

Who were the scientists that contributed to the first two parts of the cell theory?

Schleiden and Shwann

6

Was Schleiden a botonist or a zoologist?

Schleiden was a botonist.

7

3

9

What does the first part of the cell theory state?

All living things are made of cells.

10

What does the second part of the cell theory?

Cells are the basic unit of life.

11

Who contributed to the third part of the cell theory?

Louis Pasteur

12

What is the third part of the cell theory?

Life comes from life.

13

What is spontaneous regeneration?

The idea that non-living things can become living.

ie. rats moving from underneath a sack.

14

What is biogenesis?

Life can only come from life.

Why may the second part of the cell theory be disputed?

Virus' are not made of cells, so if they are considered living then the second statement is wrong.
