Answer:
Option-B
Explanation:
Schleiden was a German botanist and Schwann was a German zoologist who independently observed that plants and animals are made of cells.
Once when they together met in a conference, they shared what they observed and later both reached the conclusion that cell is the functional and structural unit of living organisms.
In the given question, since Schwann was a zoologist, therefore, he concluded that the cell in an organism must function properly whereas Schleiden was a botanist and concluded that the different structures of a plant are composed of cells.
Thus, Option-B is the correct answer.
Answer:
Both have two circuits for circulation.
Explanation:
- The two circuits of circulations are known as the systemic circuit and the pulmonary circuit.
- In the<u> systemic circuit</u> oxygenated blood from the heart is pumped to all parts of the body through the blood vessels and then the blood is pumped back to he heart.
- In the<u> pulmonary circuit</u> deoxygenated blood from all parts of the body is pumped from the heart to the lungs to be oxygenated and after it is oxygenated it is pumped back to the heart.
