Answer:
Although the nervous system is very complex, there are only two main types of cells in nerve tissue. The actual nerve cell is the neuron. It is the "conducting" cell that transmits impulses and the structural unit of the nervous system. The other type of cell is neuroglia, or glial, cell.
Enceladus, one of Saturn's moons of only
about 314 miles in diameter hides in its entrails an ocean of liquid water that
is rich in organic molecules, making it one of the places where it is most
likely to find some form of extraterrestrial life.
Europa is a strange
shaped moon of Jupiter with a large number of intersecting lines. Models
from the interior of Europe show that under a thin crust of 5 km (3 miles) of
water ice, Europa can have oceans with 50 km (30 miles) of depth or more. The
visible marks of Europa could be the result of a global expansion where the
crust could have been fractured, filled with water and frozen.
Phagocytosis is a process where cells can engulf bacteria or food.
<h3>What is phagocytosis?</h3>
Phagocytosis is a process in which cells such as macrophages surround and engulf some type of substance that the body wants to eliminate. Phagocytosis is a type of <em>endocytoses</em>. It is a process that the immune system uses to eliminate pathogens or cellular debris, finishing the material being digested by the cell, seen in processes such as infection.
We also see it in <em>apoptosis</em>, where the macrophages are going to ingest the remains of the apoptotic cell for the elimination of their cellular remains.
Therefore, we can confirm that phagocytosis is a process where cells can engulf bacteria or food.

There exist some insectivorous plants like the Pitcher plant, Venus flytrap plant, etc that are considered to be partially heterotrophic.
<h3>What are insectivorous plants? </h3>
The insectivorous plant which is sometimes also referred to as a carnivorous plant is a plant that has a special adaptation for the capturing and digesting of insects.
They can also digest some other animals by the means of unique structures like ingenious pitfalls and traps. Carnivorous nature in plants is an independent evolution and is present about six times throughout the several families and orders of plants.
There are more than 600 known species of carnivorous plants and they make for a very diverse group. In some cases, they have some more characteristics than their carnivorous nature.
Therefore, the Pitcher plant, Venus flytrap, etc are considered to be partially heterotrophic plants.
