We've got everything down to a science so I guess we know everything

It's time for a biology lesson. Here is a picture of a chloroplast. Look at it and study its components. Take as much time as you need.

Now that you've had some time to study, I'm going to give you one of the multiple choice questions I gave my students last week.

Q. All the parts of a chloroplast are

a. the outer membrane, inner membrane, stroma, thylakoid and grana.
b. the outer membrane, inner membrane, chloroplastal matrix, thylakoid.
c. the thylakoid, grana, cristae, outer and inner membranes.
d. the stroma thylakoid and grana.
e. your mom.

Including choice 'e' probably wasn't the most professional thing I've ever done, but oh well. Take that The Man!
