Answer:

False

Explanation:

Vitamin K is essential for the body. It helps in blood clotting, contributes to bone health and can be used in premature babies. However, it is not essential for the absorption of vitamin B12 from the intestine, this is the role of cyanocobalamin rather than vitamin K.

Vitamin K is essential for the body. It helps in blood clotting, contributes to bone health and can be used in premature babies. However, it is not essential for the absorption of vitamin B12 from the intestine. In the human body, the absorption of Vitamin B12 already starts in the mouth by saliva and continues until the end of the small intestine. In this process, several proteins are required for B12 uptake. Initially, R proteins secreted in saliva and gastric juice unite with it and accompany it to the duodenum, where pancreatic juice proteases break their bonds and allow their absorption.

<h3 /><h3>Why do root cells contain more mitochondria?</h3>

This has to do with the function of this organelle. The mitochondria are responsible for producing the energy needed by the cell. The root cells require more of this energy in order to undertake active transports of nutrients, which is the reason they contain more mitochondria.

Therefore, we can confirm that plant root cells get their energy through a veinous transport system within the plant as well as contain a higher concentration of mitochondria.
