A scientist is comparing two cells.


One cell, cell A, is from a unicellular organism, and the other cell, cell B, is from a multicellular organism.


What functional differences will the scientist most likely see when comparing the two cells?

A.

Cell A is very small and has only a few organelles, while cell B is very large and has many organelles.


B.

Cell A performs only one or a few functions, while cell B performs all of the organism's necessary functions.


C.

Cell A performs all of the organism's necessary functions, while cell B performs only one or a few functions.


D.

Cell A is very large and has many organelles, while cell B is very small and has only a few organelles.

Answer:

Cell A performs all of the organism's necessary functions, while cell B performs only one or a few functions.

Explanation:

There are two types of differences between unicellular cells:

  1. Structural differences
  2. Functional differences

Now, the structural differences include the size of the cell, no. of organelles etc. As we know that unicellular cell is small in size with less number of organelles while a cell from multi-cellular organism is large in size with complex structure and more no. of organelles.

But, the question here is not about structural differences but functional differences between cell.

Again, we know that unicellular organism is composed of only one cell that is able to perform all the important function required by an organism to survive. For example, a cell of Chlamydomonas is able to move, prepare its food, excrete, digest, everything that is needed for its survival.

Now, Let's talk about a cell from multi-cellular organism. We know there is division of labor among higher organisms. For example, In humans there are specific group of cells that are involved in movement (Muscle tissue), specific cells that are responsible for transmitting messages from body to brain to execute functions (called neurons).

So, when we talk about body functions of an organism, a unicellular cell will be able to perform all of those while multi-cellular cell will be a specific cell and can be able to perform only one or few specific functions of an organism's survival. So option C seems the best option.


Hope it helps! :)
