Every living organism constantly needs the exchange of substances such as nutrients, waste products, and respiratory gases with the environment in order to survive and grow. In this chapter, you will learn about transportation in plants, types of vascular tissues in plants, and movement of materials across the roots. While learning about transportation in plants, you will do several activities, including demonstration of the movement of water and sap in plants. You will also learn about transportation in animals, particularly components of vertebrate circulatory systems, the blood, mechanism of blood clotting, structure of the heart, the cardiac cycle, and the foetal circulatory system.

Dr. Mlelwa
Dr. Mlelwa is an experienced online tutor in biology and chemistry from ordinary level to advanced level. His highest level of education is two years of doctor of medicine (MD) at Muhimbili university of Health and allied science in from Nov 2018 to Sept 2020. There after he failed to continue with Doctor of Medicine Studies due to several reasons which are out of scope of this description. He started online teaching since January 2020 in his YouTube channel (Dr.Mlelwa Lectures) by that time he was still a medical student dreaming to become one among the best tutor in medical studies, that's why he called the channel Dr. Mlelwa Lectures, comparing to Dr. Najeeb Lectures who was one of his role mode. His good performance, being the second best boy in advanced biology examinations national wise in 2018, made him one among most interesting online tutor, having influence to different students inside Tanzania as well as abroad.
