Unicellular and Multicellular Quick Check ANSWERS NEEDED
Three key differences between unicellular and multicellular organisms are:
1. Structure: Unicellular organisms are composed of a single cell, while multicellular organisms are made up of multiple cells. Unicellular organisms are typically simple in structure and perform all necessary functions within a single cell. In contrast, multicellular organisms have specialized cells that perform specific functions, such as nerve cells, muscle cells, or skin cells.
2. Size: Unicellular organisms are usually microscopic in size, as they consist of a single cell. On the other hand, multicellular organisms can range in size from microscopic to macroscopic, depending on the species. The multicellular structure allows for increased complexity and size in order to accommodate different tissues, organs, and systems.
3. Reproduction: Unicellular organisms reproduce through simple cell division, which means that one cell splits into two identical cells. This process is known as binary fission. Multicellular organisms, however, have more complex reproductive mechanisms. They can reproduce sexually, involving the fusion of specialized cells, such as egg and sperm cells, which leads to genetic diversity. Additionally, multicellular organisms can also reproduce asexually through methods such as budding or fragmentation, where new individuals develop from a parent organism.
