transport system[6]
8:57 PM
We have learnt that the 3 main components of human circulatory system are the heart, blood vessels and blood respectively. I'm sure all of us would have a substantial amount of knowledge about them. And now, let's continue finding out more information about the transport system in plants!
Now, let me give all of you a brief overview of the plant's transport system.
Plants have a transport system too, in some ways similar to an animal's blood circulatory system. However, there is still a number of differences between the two. For example, there isn't a part in the plant's transport system that acts like the human heart, which pumps blood around the entire body. There isn't any circulating cells present, and also liquid do not move around continuously in plants.
The substances which are transported are- water and mineral salts, such as calcuim ions, magnesium ions, nitrate ions and phosphate ions from the soil and glucose from the leaves after photosynthesis.
In the next few posts, we will dicuss on the components that that makes up the plant's transport system, which extends from the roots, up through the stems to the leaves, flowers and fruits.
