Question

8 apply cells are not as large as this cube. explain why in terms of a cells surface area - to - volume ratio. 9 compare how is the structure of a unicellular organism different than the structure of a multicellular organism? how does this affect function? lesson 1 the characteristics of cells 13

Explanation:

8

As a cell grows, its volume increases faster than its surface - area. A large cell would have a low surface - area to volume ratio. This would limit the efficient exchange of nutrients, oxygen, and waste across the cell membrane. Smaller cells have a higher surface - area to volume ratio, which allows for more efficient transport and better cell function.

A unicellular organism is made of one cell that performs all life functions. A multicellular organism has many cells that can be specialized for different functions. In unicellular organisms, the single cell must handle processes like metabolism, reproduction, and response to the environment on its own. In multicellular organisms, cells can differentiate and work together in tissues, organs, and organ systems, allowing for more complex functions and larger body sizes.

Answer:

Cells are not large because as size increases, the surface - area to volume ratio decreases, limiting efficient transport of substances across the cell membrane.
