Cell Organelles (9/24)

Question 1

Cell membrane

Answer 1

controls what enters and exits the cell through semipermeable wall
–> hydrophilic heads LOVE water, while hydrophobic tails HATE water
(rod like vs. globular: globular pushes to control what comes in/out)

Question 2

Nucleolus

Answer 2

makes RIBOSOMES

Question 3

Nucleus

Answer 3

“in charge” because it has DNA = code for all that proteins that make up an organism

Question 4

Rough Endoplasmic reticulum

Answer 4

refines proteins for export that were produced by ribosomes

Question 5

Smooth endoplasmic reticulum

Answer 5

repairs lipids
(50% of cell membrane = lipids, so we want to make sure they’re not leaking –> do so through lipid repair)

Question 6

Golgi Apparatus

Answer 6

responsible for the packing and shipping of proteins –> shipped into VESICLES

Question 7

Mitochondria

Answer 7

converts food we eat into chemical energy (ATP!) cells can use
–> CRISTAE = where enzymes are located to do mass production of ATP

Question 8

Lysosomes

Answer 8

contain digestive enzymes to break down bacteria or old cell parts

Question 9

Centrosome/centrioles

Answer 9

centrosome = organelles
–> centriole: responsible for movement of DNA during cell division

Question 10

Cilia & Flagella

Answer 10

both help in MOVEMENT
–> cilia = smaller structures, but more NUMEROUS
–> flagella = larger structures, but SINGULAR

Question 11

Most organized to least organized DNA

Answer 11

1). Chromatin: like spaghetti in relaxed shape
2). Chromatid: more condensed for it to move easier
3). Chromosome: more compact to be able to accurately copy DNA
