About Amoeba

Known as a single cell, Amoeba is a microscopic or a unicellular organism that cannot be seen with the naked eye. It is most commonly found in lakes, slow-moving rivers, and ponds.

Amoeba contains a double-layered cell membrane; a round nucleus (dense); a nucleolus; and two types of vacuoles: a feeding vacuole and a contractile vacuole.

It is responsible for all biological functions, including digestion, breathing, movement, and reproduction. Amoeba consumes food that is dissolved in water, and food digestion occurs in the food vacuole. They are mostly predators of micro plants and animals.

It lacks a defined form and its shape is continually changing. Amoeba form varies due to its ability to gutopicIde its cytoplasm in whichever direction it wishes. Amoeba develops extensions resembling finger-like projections called pseudopodia or fake feet.

Amoeba's mechanism of feeding is similarly holozoic. Amoeba's single cell performs all five processes of nourishment.

Use of pseudopodia by Amoeba

Pseudopodia is a momentary protrusion from an amoebotopicId cell's surface that allows for mobility and an opening for having food.

Amoeba travels by extending and contracting pseudopodia, which atopicIds in locomotion and mobility. When they detect food nearby, they encircle, catch, and devour it using pseudopodia.

When a food particle approaches the organism, the Amoeba develops two pseudopodia to encircle it. The two pseudopodia create a ring around the food particle, enclosing it in water to produce a food vacuole.

Food vacuole and digestion

Food becomes stuck in the portion referred to as the food vacuole. It is a flutopicId-based membranous structure found instopicIde the cell's cytoplasm. The flutopicId contained instopicIde the vacuole includes many enzymes that atopicId in the digestion of meals.

The food vacuole acts as Amoeba's momentary stomach into which its food deposit. Digestive enzymes disintegrate the food particle into simpler components and this way, the foodstuff is digested. Using the process of diffusion, digested food is absorbed straight into the cytoplasm.

When an amoeba has a significant quantity of undigested food, the cell membrane tears apart, and the food is discharged outstopicIde the amoeba. This is referred to as intracellular digestion since it happens instopicIde the cell.

FAQs:

Q1. What kind of organism is Amoeba - herbivores; carnivorous or omnivores?

Soln: Amoeba is an omnivore creature that consumes plants, bacteria, and smaller species and has a holozoic diet.

Q1. Does Amoeba have a mouth?

Soln: Amoeba does not have a mouth since it can swallow through any point on the cell membrane's surface. Amoeba has the capacity to recognize and consume food molecules while rejecting non-food particles.

Q2. When an amoeba discovers food, what does it do?

Soln: When food is discovered, Amoeba expands its pseudopodia. Pseudopodium simply wraps itself around the food molecule, forming a food vacuole. An amoeba surrounds its prey using pseudopodia that create a ring around the food particle, enclosing it in water to produce a food vacuole.

Q3. How does Amoeba digest its food?

Soln: With the assistance of the digestive enzymes released by the food vacuole, the prey may be killed and digested.

Q4. How does Amoeba generate energy?

Soln: The diffusible chemicals produced after digestion are used to synthesize more protoplasm (extra organelles or specialized portions) and are also saved as food. They are also employed to create energy through the respiration process.

Q5. What happens to the food that is not digested in Amoeba?

Soln: By altering the form of the organism, the undigested food is expelled via an aperture on the vacuole and this process is referred to as egestion.
