THE STREAMING MOVEMENT OF CYTOPLASM OBSERVED IN A FRESHLY CUT LEAF OF A WATER PLANT IS TERMED
- A. amoeboids
- B. centrifugal motion
- C. ciliary motion
- D. cyclosis ✓
- E. osmosis
The answer to the question is: D. cyclosis
Cyclosis, also known as cytoplasmic streaming, is the movement of the cytoplasm within a cell. This phenomenon is commonly observed in plant cells, particularly in cells with large central vacuoles, such as those found in water plants like Elodea. In cyclosis, the cytoplasm flows in a circular motion around the cell, driven by actin filaments and myosin motor proteins.
During cyclosis, organelles and other cellular components are transported throughout the cell, allowing for the distribution of nutrients, hormones, and other essential substances. This movement is vital for cellular processes such as growth, metabolism, and response to environmental stimuli.
In the context of a freshly cut leaf of a water plant like Elodea, the streaming movement of cytoplasm can be easily observed under a microscope. The swirling motion of the cytoplasm within the cells is characteristic of cyclosis and plays a crucial role in maintaining cellular functions in plant tissues.
