Ingestion of foreign substances by macrophages and yeast cells by an amoeba is known as <u>Phagocytosis</u>
<u>Explanation:</u>
Phagocytosis that is the name given to the process of ingestion of foreign particles by macrophages. In human body the white blood cells does this function. Macrophages is found in all the tissues. Any foreign particle entering the body is engulfed by this process hence protecting the organisms.
Once a bacteria enters the body it is at once detected and recognised as the foreign particle. Then it is attached to the phagocyte. Then it is engulfed into a vesicle called phagosome. Then this is killed by the process of phagocytosis.
The movement of nutrients into the vascular stele requires energy, unlike the movement of water that does not require energy. This energy is provided by the phloem. Sugars are produced in the leafs, as part of the photosynthesis process, so whenever a new root is growing, or a fruit needs to grow, the phloem gets in action. With the help of the water the sugars get in the phloem, which can most simply be seen as an elevator inside the plant, that is moving nutrients up and down, on the places in which they are most needed.
