Unit 2: Chapter 04 Homework- A Tour of the Cell

Which of the following is part of the endomembrane system?

Golgi apparatus

Which plant cell organelle converts chemical fuel into packets of chemical energy that can power the cell?

Mitochondrion

The structural framework in a cell is the

cytoskeleton

The ____________________ builds compounds, whereas the ________________ breaks things down.

endoplasmic reticulum; lysosome

Where in a cell is ATP made?

mitochondria

Where is the genetic information of the cell stored?

nucleus

One of the ways smooth endoplasmic reticulum (ER) differs from rough endoplasmic reticulum is that rough ER is covered by

ribosomes.

Where are lipids made in the cell?

smooth endoplasmic reticulum (ER)

_____ are found only in plant cells, but _____ are found in both plant and animal cells.

Central vacuoles; ribosomes

Drag the correct label under each cell structure to identify whether it is found only in animal cells, only in plant cells, or in both types of cells.

Lysosome- Found in ANIMAL cells but not most plant cells Cell Wall- Found in PLANT cells but not animal cells Nucleus- Found in both PLANT and ANIMAL cells Chloroplast- Found in PLANT cells but not animal cells Rough ER- Found in both PLANT and ANIMAL cells

Drag the correct description under each cell structure to identify the role it plays in the cell.

Mitochondrion- Converts chemical fuel into packets of chemical energy (ATP) that can power the cell Chloroplast- Makes food by converting light energy into chemical energy Golgi Apparatus- Modifies and packages proteins Plant Cell Wall- Strong, protective structure made from cellulose fibrils Central Vacuole- Regulates cytoplasm composition, creates internal presure, and stores cell compounds

Drag the correct description under each cell structure to identify the role it plays in the cell.

Nucleus- Stores the genetic information of the cell. Lysosome- Breaks down macromolecules using digestive enzymes. Mitochondrion- Converts chemical fuel ino packets of chemical energy that can power the cell. Ribosome- Works with mRNA to synthesize proteins. Smooth ER- Site of lipid synthesis.

Drag the labels onto the flowchart to trace the movement of proteins through the endomembrane system and out of the cell.

Rough ER> Vesicle from ER>Golgi apparatus>Vesicle from Golgi>Plasma Membrane

Which of the following is a function of the central vacuole?

Storing compounds produced by the cell

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 and ________________ break down these sugars to create ATP

chloroplasts; mitochondria

The plant cell wall

is a protective structure made of cellulose fibrils.

Which of the following organelles breaks down worn-out organelles?

lysosomes

What carries instructions for making proteins from the nucleus into the cytoplasm?

mRNA

What structure acts as a selective barrier, regulating the traffic of materials into and out of the cell?

plasma membrane
