Cell Organelles

Here are some various drawings of an idealized animal cell, showing all the different types of organelles.  Different artists depict them slightly differently, so looking at many versions should be helpful.  If you click the "source" link under each picture, you will find many great websites with further information.  In some cases this will be necessary to be able to see the image.  My black background is messing some of these up, sorry about that.
Look at these to orient yourself, we will then go into detail on each organelle, and then have some unlabeled cell drawings so you can quiz yourself.  Enjoy!

Organelles
Here are some closeups! :D

Cell membrane


Here is a good depiction of the various things embedded into a cell's plasma membrane (also referred to as the phospholipid bilayer):

Nucleus

Notice the pores, which is where the mRNA (post-transcription) would emerge to go to a ribosome for translation.

Mitochondria

Here is a labelled mitochondria.  Please note, Matrix and Cristae will come into play when you learn about metabolism.

And, here is a really sweet video of a mitochondrion, showing some metabolism processes.  FYI Mitochondrion is singular, Mitochondria is plural.  (Link to the animator's website, for better quality, and links to other really cool videos: http://www.xvivo.net/powering-the-cell-mitochondria/)

  2. LOL. This wasn't intended to teach you everything, this was a study resource for a Physiology class to review for their exam. Better luck next time.
