Review for Unit 2: Cell Structure and Function (Chapter 7)
1. List the three parts of the cell theory:
This is the
__________________________________________________ short
__________________________________________________ answer
__________________________________________________ question.
2. People and Ideas: Who is responsible for each of the following:
___________ All cells come from preexisting cells
___________ Saw microorganisms with a microscope
Page 28__________ believed in spontaneous generation
29 in NB
__________ discovered that all animals are made of cells
___________ discovered that all plants are made of cells
___________ disproved spontaneous generation
3. Which organelles have the following functions?
__________ controls cell activities (like a brain)
__________ is the collecting and packaging center (packs and stacks)
__________ controls what enters and leaves the cell
Page 30
__________ Is the site of ribosome synthesis (full of RNA )
& Poem
__________ the power house (with ATP, responsible for ENERGY) in NB
__________ recycles cell materials (it is ‘suicide’ for molecule to enter)
__________ stores materials (can hold food or other cell products)
__________ site of protein synthesis (they are really keen!)
__________ carbohydrate production centers (only plants have them)
__________ the plumbing system of the cell (attaches all the ‘thingies’)
