Link between procaryotes and multicellular eucaryotes :–

Options

A. Cyanobacteria
B. Protista
C. Fungi
D. Plants

Answer

**Step-by-Step Solution:**

1. **Understanding Prokaryotes and Eukaryotes:**
- Prokaryotes are unicellular organisms that lack a defined nucleus and membrane-bound organelles. Examples include bacteria and archaea.
- Eukaryotes are organisms whose cells have a nucleus and other organelles enclosed within membranes. They can be unicellular or multicellular, such as plants, animals, fungi, and protists.

2. **Identifying the Link:**
- The question asks for the link between prokaryotes and multicellular eukaryotes. The kingdom that serves as a bridge between these two groups is **Protista**.

3. **Characteristics of Protista:**
- Protista includes a diverse range of organisms, both unicellular and multicellular, that possess eukaryotic cells.
- Some protists, like dinoflagellates, exhibit unique characteristics that show a blend of prokaryotic and eukaryotic features.

4. **Example of Dinoflagellates:**
- Dinoflagellates are a type of protist that are flagellated and exhibit a mesokaryotic nature. This means they have a well-organized nucleus similar to eukaryotes, but during cell division, they divide in a manner reminiscent of prokaryotes (through a process called amitosis).

5. **Conclusion:**
- Therefore, the kingdom **Protista** is significant as it contains organisms that display characteristics of both prokaryotes and eukaryotes, thus forming a link between them.

**Final Answer:**
The link between prokaryotes and multicellular eukaryotes is the kingdom **Protista**.
