Answer 16

Cell Theory

Hooke only observed cell walls because cork cells are dead without cytoplasmic contents.

Answer 17

TRUE

Question 18

The cell is derived from the Latin word [ ] which means small compartment.

Answer 18

Cellula

Question 19

He is given the credit for the invention of the first compound. Since he was young at that time, it’s possible that his father, Hans, made the first one, yet he perfected the production.

Answer 23

Cytoblast

Question 24

He reasoned that if there really is a correspondence between the vegetable and and animal tissues that he suspected, and if the nucleus is so important in the vegetable cell as Schleiden believed, then the nucleus should also be found in the ultimate particles of the animal tissue.
