Amoeba Anatomy and Functions
a) Label the parts A, B, C, and D of the given organism.
Can you identify the different parts of the amoeba and their functions?
b) How are false feet formed in amoeba?
What is the process through which amoeba forms false feet?
c) What is the function of the part labeled as C?
What role does part C play in the survival of the amoeba?
d) The organism consists of two types of vacuoles, i.e., contractile vacuole and food vacuole. Food vacuole consists of food particles. What is the role of the contractile vacuole?
What is the significance of the contractile vacuole in the life of an amoeba?
Answer:
a) The organism is labeled: A- Nucleus, B- False feet, C- Contractile vacuole, D- Food vacuole.
b) False feet are formed in amoeba through cytoplasmic streaming.
c) The contractile vacuole regulates water content and d) the role of the contractile vacuole is excretion of excess water.
a) Label the parts A, B, C, and D of the given organism:
A - Nucleus
B - False feet
C - Contractile vacuole
D - Food vacuole
b) How are false feet formed in amoeba:
False feet, also known as pseudopodia, are formed in amoeba through the process of cytoplasmic streaming. The cytoplasm of amoeba flows towards a particular point, extending the cytoplasm outwards to form pseudopodia.
c) What is the function of the part labeled as C:
The part labeled as C, the contractile vacuole, has the function of regulating the water content in the amoeba. It collects excess water and expels it from the cell, maintaining osmotic balance within the organism.
d) What is the role of the contractile vacuole:
The contractile vacuole plays a crucial role in the excretion of excess water from the amoeba. It helps maintain the proper balance of water and prevents the cell from bursting due to excessive water intake. The food vacuole, on the other hand, is responsible for storing and digesting food particles.
