Amoeba captures food with the help of
pseudopods
very nice but in short .
answer is too short .
Amoebas capture food with the help of their pseudopodia. Pseudopodia are extensions of the amoeba's cell membrane that can be protruded in any direction. These extensions are like temporary "arms" that the amoeba uses to surround and engulf its food.
To understand how an amoeba captures its food using pseudopodia, let's break it down into steps:
1. Detection: An amoeba senses the presence of food molecules in its environment. It can detect food through chemical cues or by sensing changes in its surroundings.
2. Extension: Once the amoeba detects food, it extends its pseudopodia towards the food source. The pseudopodia are flexible and can be extended in any direction the amoeba desires.
3. Enveloping: The pseudopodia surround the food particles, forming a temporary "sac" around them. This process is known as phagocytosis. The pseudopodia fuse together, enclosing the food within a membrane-bound structure called a food vacuole.
4. Internalization: The amoeba then brings the food vacuole containing the captured food particles inside its cytoplasm.
5. Digestion: Within the food vacuole, the amoeba releases digestive enzymes to break down the captured food into smaller molecules. These smaller molecules are then absorbed by the amoeba's cytoplasm and used for energy and growth.
6. Waste elimination: After digestion, any indigestible material or waste is expelled from the amoeba's cell through a process called exocytosis.
So, in summary, amoebas capture food with the help of their pseudopodia by extending them towards the food source, enveloping the food particles, and bringing them inside their cell for digestion.
