Back to the Question

Now back to the question-why is the difference between the food transport system in the plants and the animals.

Plants:

The food(glucose) is produced during photosynthesis and transported to other parts of the plant via the phloem and excess is stored as starch.

The water and mineral salts absorbed by the roots are transported to other parts of the plant through the xylem.

Animals:

Food and water passes through various parts of the digestive system in the following order:

Mouth
Esophagus
Stomach
Duodenum
Ileum
Colon
Rectum
Anus
Toilet(joking)

Much digestion takes place in the small intestine and nutients,simple sugars and amino acids are absorbed into the blood stream and to the cells. Fatty acids and glycerol pass through to the lymphatic system.While in the large intestine, water and dissolved salts are absorbed.

This much summarise my 2nd question and this may be my last post.

Below is a crazy video about the human digestive system.

Animal digestive systems

Below are different pictures of digestive systems of different animals, which differs from what they eat. But many of them have some things in common-the food which they eats travels from they mouth, down the oesophagus(which is the gullet),into the stomach where food is broken down by the gastric juice, down the small intestine, through the large intestine, stored in the rectum and finally out through the anus. Basically this process takes about 24 to 72 hours.

Transport system in animals

There are a few systems in animals such as the respiratory system, circulatory system...but I will be concentrating on the digestion system...

Here's a video with some relavance to the transport system in plants

transport in plants

After doing research on the transport system in plants, i found out that plants transport system is made up of two tubes-the xylem vessels, and the phloem vessels(which I knew).But the interesting part is that the xylem tubes are made of dead cells while the phloem of living ones!!!

Next Topic

Now the next topic-transport in living things.What is the difference between the transportational system of food, waer, and minerals in animals and plants?
I will be doing more research to find out.
