Question

Streaming of protoplasm in amoeba is an example of
A. Locomotion
B. Movement
C. Both A and B
D. None of the above

Answer 1

Hint: Amoeba is a unicellular organism. Protoplasmic streaming is also called protoplasmic streaming. It can help in the transport of fluid. Locomotion refers to the change in position of the body while movement refers to the changes in the body part. It helps in the movement of body parts of the amoeba.

Complete answer:
The movement of the fluid substance within a plant or animal cell is called cytoplasmic streaming or protoplasmic streaming and cyclosis. It increases the rate of transport of molecules and organelles around the cell. Larger plant and animal cells show this type of movement. It depends on the temperature, in the high-temperature rate of protoplasmic streaming is high.
The movement of part of the body leads to a change in the position and location of the organisms which is called locomotion. Movements like walking, running, jumping, crawling, climbing, swimming, flying, galloping, slithering, and so on are observed in multicellular organisms.
Protoplasmic streaming is the movement of fluid. If one of the proteins does not transport and remain attached with a substrate, such as a microfilament or a microtubule. In this condition, motor proteins can move organelles and other molecules through the cytoplasm.
In unicellular organisms such as amoeba, this type of protoplasm streaming can provide the mechanism for cell locomotion. It helps in the movement of body parts of the amoeba. The microfilaments provide the driving force to control the direction of the streaming.
From the above information, we can say that the streaming of protoplasm in amoeba is an example movement.

Hence, the correct answer is option (B).

Note: Protoplasmic streaming enables the movement of motor molecules of the plant cell. The rate of cytoplasmic flow can range between 1 and 100 micron/sec. At the neutral pH cytoplasmic streaming is highest and it decreases at both low and high pH. Due to the addition of Lugol’s iodine solution and Cytochalasin D, the flow of the cytoplasm can be stopped.
