Amoebas use cytoplasmic streaming to trap food particles and move. Cytoplasmic streaming is caused by microfilament movement in the cytoskeleton of an amoeba. The cytoplasmic streaming allows the amoeba to surround its food particles. The arm like projects that seem to come out of the amoeba are called pseduopodia. When the cytoplasm completely surrounds the food particles it forms a vacuole around them.
The pseduopodia also allow the amoeba to move.
What else can I help you with?
Amoebas move by using extenions of their cytoplasm called?
The ameba makes a "false foot" extension called a pseudopod. The cytoplasm inside the cell is capable of changing into different states. It can turn very easily from a fluid into a solid state and vice versa. The fluid state of the cytoplasm is called plasmasol, the more solid state is called plasmagel. When the organism locomotes the plasmasol flows through the center of the cell towards the front. When the plasmasol moves to the sides it becomes solid again. This way the cell can propel itself as a whole but can also send pseudopodia in many directions.
What are choanocytes responsible for?
Choanocytes are responsible for generating water currents and capturing food particles in sponges. They have a flagellum that creates the current and a collar of microvilli that trap and engulf food particles. Choanocytes play a crucial role in filter feeding and nutrient uptake for sponges.
What part of the body secretes mucus to trap and move dust and debris?
Goblet cells. They are located in the epithelium of many organs along with other cells. But, they are more prominent in the intestinal and the respiratory tracts.
Where does amoeba obtain its food?
The amoeba in Figure 15 belongs to the group of protozoans called sarcodines. Sarcodines move and feed by forming pseudopods (soo duh pahdz)---temporary bulges of the cell. The word pseudopod means "false foot." Pseudopods form when cytoplasm flows toward one location and the rest of the organism follows. Pseudopods enable sarcodines to move. For example, amoebas use pseudopods to move away from bright light. Sarcodines also use pseudopods to trap food. The organism extends a pseudopod on each side of the food particle. The two pseudopods then join together, trapping the particle inside. FROM SCIENCE EXPLORER 2009 LIFE SCIENCE BOOK
What are tiny hairs that trap dust and pollens?
Cilia are tiny hairs that line the respiratory tract and help trap dust and foreign particles to prevent them from entering the lungs. These hair-like structures wave in a coordinated manner to move mucus and trapped particles out of the respiratory system.
What is the MAIN function of the mucous glands and ciliated epithelial cells that line the airway tubes of the respiratory system?
To trap inhaled particles and move them out of the airways.
Animal like protists that use structures called?
Animal-like protists that use structures called pseudopods to move and feed are known as amoebas. These organisms are able to extend and retract these pseudopods to capture food particles and propel themselves through their environment.
What is the purpose of the tentacles of coral polyps?
They trap tiny particles of food as they drift by.

How does the lymphatic system proct the body from diseases?
Nodes in the lymphatic system can act as filters to trap foreign particles and so often trap cancerous cells on the move.
Why are planarians known as scavengers?
because they move around very quick and trap their food and scavenge for bacteria and food.
What is theMAIN functionof the mucousglands andciliatedepithelial cellsthat line theairway tubes ofthe respiratorysystem?
To trap inhaled particles and move them out of the airways.
What type of food does a fanworm eat?
Fan worms are filter feeders. Their frilly tentacles are lined with cilia, which beat continuously to move water over the tentacles. Mucus on the tentacles trap small particles from the water which are passed down to the mouth (located in the middle of the tentacles) and eaten. Exactly what they eat depends on the species of worm: larger worms can trap and eat larger particles than smaller species. The smallest worms can filter and eat particles the size of bacteria.

What do littleneck clams eat?
Littleneck clams filter particles, mainly plankton, from the water. They also trap bits of food in the mucus with which they cover their shells.
