compare the differences between unicellular, colonial and multicellular organisms by:
– investigating structures at the level of the cell and organelle,
– relating structure of cells and cell specialisation to function.
Answer (1)
Answer: comparison:Unicellular: * Structure: Single cell with all necessary organelles (e.g., mitochondria, ribosomes, nucleus). May have specialized structures like flagella. * Function: One cell performs all life functions; no cell specialization.Colonial: * Structure: Group of similar cells living together. Minimal cell specialization may occur, but individual cells can often survive alone. * Function: Some division of labor, but not essential for individual cell survival. Offers benefits like increased size.Multicellular: * Structure: Many specialized cells organized into tissues and organs. Organelles are abundant and arranged to support specific cell functions (e.g., many mitochondria in muscle cells). * Function: Extensive division of labor. Cell specialization increases efficiency in life processes (e.g., muscle cells for movement, nerve cells for signaling). Cell structure directly supports its specialized role.
