Tour of the Cell Chapter 4
Central vacuole
Regulates cytoplasm composition, creates internal pressure, & stores cell compounds.
Smooth ER
Site of lipid synthesis
Nucleus
Stores the genetic info of the cell
The plasma membrane would fit into which general function category?
Support, movement, & communication
What is a typical function of lysosomes?
Breaking down of damaged organelles, such as mitochondria
Lysosome
Breaks down macromolecules using digestive enzymes
What are the three organelles that plant cells have but animal cells do not?
Chloroplast, central vacuole, cell wall
Plant cells have two energy-related organelles. _ harness light energy to create sugars & _ break down these sugars to create ATP.
Chloroplasts, mitochondria
Mitochondria
Converts chemical fuel into packets of chemical energy ATP that can power the cell.
Mitochondria
Converts chemical fuel into packets of chemical energy that can power the cell.
Where are the chlorophyll molecules located within the chloroplasts?
Embedded in the thylakoid membrane
Which organelles comprise the endomembrane system of a cell?
Endoplasmic reticulum, Golgi Apparatus, lysosome
The _ builds compounds, whereas the _ breaks things down.
Endoplasmic reticulum, lysosome
Chloroplast
Makes food by converting light energy into chemical energy
Mitochondria appear in greatest numbers in cells that are...
Metabolically active
Golgi apparatus
Modifies & packages proteins
Animal cells are surrounded by a _ whereas plant cells are also surrounded by a _
Plasma membrane, cell wall
How are cell surface proteins exported out the cell?
The protein is folded, then packaged for transport to the Golgi apparatus.
Ribosome
Works with mRNA to synthesize proteins
