The picture provided shows the
organism Amoeba proteus viewed under a microscope. Why does this organism not contain
multiple specialized cells? (A) This statement is incorrect; it
does contain multiple specialized cells. (B) Because it does not need to
move or respire. (C) Because it is unicellular. (D) Because it is not alive.
Let’s first explore the concept of
specialization. Then, we’ll look back at this
amoeba.
In biology, structure and function
are closely related. The structure of a particular
biological component or organism often relates to its function. Cells that have particular
structures suitable for specific functions are said to be specialized. For example, a neuron has many
branches that allow it to conduct electrical signals from one part of the body to
another. And a sperm cell is specialized
because its long tail is ideal to help it swim toward the egg in order to fertilize
it.
Now we can look back at the
amoeba. This organism is adapted for its
specific lifestyle. But why does it not contain
multiple specialized cells as the question is asking? The key word here is
“multiple.” Amoeba do not contain multiple
cells because they are unicellular, meaning they only contain a single cell. Additionally, as suggested by
incorrect answer choices, amoeba are indeed alive, are capable of movement, and
undergo cellular respiration to meet its energy requirements.
So, getting back to our question,
the option that correctly describes why this amoeba doesn’t contain multiple
specialized cells is given by answer choice (C): because it is unicellular.
