The cells of protists need to play out the majority of the capacities that different cells do, for example, develop and duplicate, look after homeostasis, and get vitality. They also need to obtain “food” to provide the energy to perform these functions.
Some animal-like protists use their “tails” to eat. These protists are called filter-feeders. They acquire nutrients by constantly whipping their tails, called flagellum, back and forth. The whipping of the flagellum makes a present that brings food into the protist.
Other animal like protists must “swallow” their food through a system called endocytosis.
Endocytosis happens when a cell takes in substances through its membrane.
The process is described below:
1.The protist wraps around its prey, which is usually bacteria.
2.It makes a sustenance vacuole, a kind of “nourishment stockpiling compartment,” around the microscopic organisms.
3.The protist produces toxins which paralyze its prey.
4.Once digested, the food material moves through the vacuole and into the cytoplasm of the protist.
Some protists are plant-like and photosynthesize.
Some protists absorb nutrients from decaying matter like a fungus.
A few protists chase their sustenance or go about as parasites.
