When things the amoeba wants to eat - other cells, little food particles, etc. - stick to surface molecules (the term for surface molecules that recognize and bind to specific factors - proteins, sugars, hormones - is receptors), the shape changing machinery is set in motion, and the membrane flows around the particle of lunch. When it's surrounded, the membrane comes in contact with itself on the other side of the particle and merges, actually capturing the particle within the amoeba in a little membrane-covered bubble, called a vacuole. This process is called "phagocytes", which basically means cell eating.

Process that amoebas use to take in food and other materials?
Amoebas use phagocytosis to take in food and other materials. During phagocytosis, the amoeba extends its cell membrane around the particle and engulfs it, forming a food vacuole. The food is then digested inside the vacuole.
What do amoeba's excrete?
Amoebas excrete waste through a process called exocytosis, where they expel undigested food particles and other waste materials from their cell membrane. This helps to maintain the amoeba's internal environment and prevent the accumulation of harmful substances.
Do Amoebas have hair?
No, amoebas do not have hair. They are single-celled organisms that lack specialized structures like hair. Their shape can change as they move and engulf food through a process called phagocytosis.
What is a disadvantage of how the amoebas move and feed?
One disadvantage of how amoebas move and feed is that their method of engulfing food particles through phagocytosis can be energy-intensive and time-consuming. This process requires a significant amount of energy and can limit the amount of food that can be consumed efficiently.
The process of breaking down food into usable materials?
Digestion is the process of breaking down food into usable materials, and is one function of the digestive system. The other function, absorption, makes these materials available to all cells in the body.

What does amoeba eat by?
To eat, the amoeba stretches out the pseudopod, surrounds a piece of food, and pulls it into the rest of the amoeba's body. Amoebas eat algae, bacteria, other protozoans, and tiny particles of dead plant or animal matter. Amoebas reproduce (make more amoebas) by a process called binary fission.
What do amoeba's excrete?
Amoebas excrete waste through a process called exocytosis, where they expel undigested food particles and other waste materials from their cell membrane. This helps to maintain the amoeba's internal environment and prevent the accumulation of harmful substances.
What specific organism relies on Endocytosis?
One specific organism that relies on endocytosis is the amoeba. Amoebas use endocytosis to engulf and take in food particles or other substances from their environment. This process allows them to obtain nutrients and energy for survival.
Do Amoebas have hair?
No, amoebas do not have hair. They are single-celled organisms that lack specialized structures like hair. Their shape can change as they move and engulf food through a process called phagocytosis.
How do the amoeba get their food?
AMOEBAS use pseudopods to get food...

How do amoebas and white blood cells take in food?
By the process of engulfment Amoebas take in food by phagocytosis, whereby small particles are engulfed by the cell and carried to the cytoplasm. Technically, white blood cells do not "take in food," however, the mechanism by which they engulf microorganisms, cellular debris, or other waste products is phagocytosis as well.
What forms food vacuoles to digest food particles?
amoebas
Does amoeba have jaws?
No, amoebas do not have jaws. They capture their food by surrounding it with their cell membrane and engulfing it through a process called phagocytosis.
Does an amoeba have a jaw?
No, an amoeba does not have a jaw. Amoebas are single-celled organisms that engulf food particles through a process called phagocytosis, where the cell membrane surrounds the food and forms a food vacuole for digestion.
