Bozeman 017 - Compartmentalization 2.b.3 and Boz 43 - Organe

Why are cells small?

• gravity would have too much impact on large cells
• cells need a large surface area to volume ratio
• large cells take too much energy to grow
• signals can not get from one end of a large cell to another

Eukaryote cells increase surface area for increased space for chemical reactions by having lots of...

• internal membranes

• outgrowths of the cell membrane

• tiny cells inside the larger cell

• always being very flat

Compartmentalization also helps Eukaryote cells to...

• keep competing reactions in separate areas of the cell 
• divide into two new daughter cells
• look really fancy under a microscope
• require fewer resources to live

The rough Endoplasmic Reticulum (ER) functions to...

• make proteins that are packaged to send to other places
• makes lipids
• makes steroids
• breaks down toxins in the cell

Proteins made inside the Rough ER are...

• trapped in membrane vesicles & sent to Golgi or out of cell

• immediately destroyed

• used to make more Ribisomes for the ER

• sent directly to the nucleus

All of these are true about Lysosomes EXCEPT

• they work to detoxify the cell 
• They digest and recycle old cell parts
• Responsible for programmed cell death (apoptosis)
• Are a lipid sac containing enzymes

All of the following are true about Vacuole EXCEPT

• storage of pigments and poisions in plants

• storage and regulation of water in plants

• vacuoles increase surface area of cells

• help produce energy for the cell

 All Eukaryote cells contain...

• mitochondria, but only some have chloroplasts
• chloroplasts, but only some have mitochondria
• either chloroplasts or mitochondria, but never both

 Ribosomes are made up of..

• rRNA and protein, made in the nucleolus
• rRNA and protein, made in the ER
• only rRNA, made in the nucleolus
• only protein, made in the ER

All of the following are jobs of the Golgi Body (Apparatus) EXCEPT 

• receiving proteins in vesicles from the ER
• sending protein vesicles to the cell membrane
• modifying proteins
• digesting proteins
