Looking Inside Cells
(Cell Structure)
3.2
Learning Objective:
• What role do the cell wall and cell membrane
play in the cell?
• What is the role of the nucleus in the cell?
• What organelles are found in the cytoplasm
and what are their functions?
• How do cells differ?
Organelle Micrographs
Enter the Cell
• Plant Cell vs
Animal Cell
• Plant cells have two major
structural differences. Plant
cells have a cell wall and
chloroplast, animal cells do not
• Cell Diversity
• The variety of structures in cells
reflects differences in cell
function.
The Nucleus
• Nucleus
• Nuclear
Envelope
• Chromatin
• Nucleolus
• Acts as the control center for
the cell
• Protects the nucleus, allows
materials to pass in and out
through pores
• Thin strands containing genetic
material that directs the cell’s
function
• Where ribosomes are made
(ribosomes make proteins)
