happy to help again :)
The average red blood cell lives for 120 days.
2. There are 2.5 trillion (give or take) of red blood cells in your body at any moment. To maintain this number, about two and a half million new ones need to be produced every second by your bone marrow.That's like a new population of the city of Toronto every second.
3. Considering all the tissues and cells in your body, 25 million new cells are being produced each second.That's a little less than the population of Canada - every second !
4. A red blood cell can circumnavigate your body in under 20 seconds.
5. Nerve Impulses travel at over 400 km/hr (25 mi/hr).
6. A sneeze generates a wind of 166 km/hr (100 mi/hr), and a cough moves out at 100 km/hr(60 mi/hr).
7. Our heart beats around 100,00 times every day.
8. Our blood is on a 60,000-mile journey.
Answer:
Vacuoles.
Explanation:
Eukaryotic cells contain well membrane bound nucleus. Their cell organelles are divided into structural and functional compartment by the endomembrane system.
The large compartment that maintains turgor pressure is vacuole. Vacuoles are generally present in plants and maintain the disposal of cellular waste and storage of toxic materials.
Thus, the answer is vacuole.
They are also describe as a plant with naked seeds because during pollination ovule is not enclosed by the carpel except some kind of scales during development .....In contrast the angiosperm have evolved flower hence they are also called flowering plants
