10 Questions
What is the function of pseudopodia in Amoeba?
Movement and capturing food
Which organelle in Amoeba traps the food particles?
Vacuole
What is the role of the cell membrane in Amoeba?
Regulate movement of substances
What happens to the food particles once engulfed by Amoeba's pseudopodia?
Transported to vacuoles
What is the function of the nucleus in Amoeba?
Contains genetic material
How does Amoeba move and capture food?
Amoeba moves and captures food by extending pseudopodia or false feet.
What are the main components found in Amoeba's cytoplasm?
In Amoeba's cytoplasm, you can find a rounded dense nucleus and many small bubble-like vacuoles.
How does Amoeba engulf food particles?
Amoeba engulfs food particles by pushing out pseudopodia around the food particle and engulfing it.
Explain the feeding process of Amoeba when it detects food.
When Amoeba senses food, it extends pseudopodia around the food particle and engulfs it to form a food vacuole.
What is the function of vacuoles in Amoeba?
Vacuoles in Amoeba play a role in storing and digesting food particles.
Study Notes
Amoeba Structure and Function
- Pseudopodia in Amoeba function as extensions that help capture food and move the organism.
- The organelle responsible for trapping food particles is the food vacuole.
Cell Membrane
- The cell membrane in Amoeba is semi-permeable, allowing selective passage of substances in and out of the cell.
Food Engulfment and Digestion
- Once engulfed by Amoeba's pseudopodia, food particles are trapped in a food vacuole.
- Within the food vacuole, digestive enzymes break down the food into smaller molecules.
Nucleus
- The nucleus in Amoeba contains the genetic material and regulates cellular activities.
Locomotion and Feeding Mechanisms
- Amoeba moves and captures food through the formation and retraction of pseudopodia.
- The feeding process involves the detection of food, protrusion of pseudopodia, and engulfment of food particles.
Cytoplasm Composition
- Amoeba's cytoplasm primarily consists of water, salts, sugars, and various organelles such as mitochondria, ribosomes, and lysosomes.
Vacuoles
- Vacuoles in Amoeba function as storage units for nutrients, waste, and other substances.
