3 to 4 paragraphs discussion question 


When you look around at the world, you can see many examples
that demonstrate how an object’s or a system’s structure relates to its
function. The structure of a highway system, for example, can affect traffic
flow. You can, no doubt, think of many other examples.

In this Discussion Board assignment, you will look at the
structure of the most basic unit of life, the living cell. You will also
investigate how the structures of cells are directly related to the functions
that are important to life.

Part 1

Your text describes the difference between the organelles in
a eukaryotic cell and the more simple structure of a prokaryotic cell as an
analogy between the chief executive officer’s (CEO’s) corner office and a
cubicle. Organelles are like appliances or pieces of furniture that perform
specific functions. Choose 1 organelle, and use an analogy to explain its
function. For example, explain how a chloroplast is like a solar panel, or how
a mitochondrion is like a furnace. Try to think of original analogies for other
organelles or cell structures such as golgi, lysosome, cell wall, cell
membrane, endoplasmic reticulum, ribosomes, nucleus, and so on. Include how
your analogy may be less than perfect.

Part 2

You will read that only plants, algae, and some bacteria are
photosynthetic. There is an exception to this, though. One species of sea slug
has found a way to steal chloroplasts, store them in cells lining its digestive
tract, and live on the sugar that is produced (Milius, 2010). What benefit
would there be for animal cells (including those of humans) to make their own
food? Could cell, tissue, or genetic engineering allow humans to use
chloroplasts this way? Describe 1 or 2 factors that would need to be considered
for chloroplasts to function in an animal or a human.

plant. Retrieved from
