Amici (1818) studied cyclosis for the first time in

Options

A. Hydrilla
B. Amoeba
C. Chara
D. Acetabularia

Answer

**Step-by-Step Solution:**

1. **Identify the Scientist and Year**: The question asks about the scientist who studied cyclosis for the first time and the year it was studied. The answer is Amici in 1818.

2. **Define Cyclosis**: Cyclosis refers to the streaming movement of the cytoplasm within a cell. This movement is essential for various cellular processes.

3. **Location of Cyclosis**: Cyclosis occurs in the cytoplasm of the cell, which is the gel-like substance that fills the cell and surrounds the organelles.

4. **Mechanism of Cyclosis**: The streaming movement of the cytoplasm is facilitated by microfilaments, which are structures made up of proteins, specifically actin. These microfilaments play a crucial role in the movement of the cytoplasm.

5. **Organism Studied**: Amici studied cyclosis in a specific organism known as "Chara," which is a type of green alga. This organism was chosen for its clear visibility of cytoplasmic streaming.

6. **Conclusion**: In summary, Amici studied cyclosis for the first time in 1818 in the green alga Chara, observing the streaming movement of the cytoplasm facilitated by microfilaments.
