Types Of Cells And Cell Stuctures 4.1-2

Question 1

Nucleus

Answer 1

This acts as a “control center” for all activities performed by the cell.

Question 2

What is the storage source of genetic information (DNA)?

Answer 2

Nucleus

Question 3

What does the Nuclear Envelope/Membrane act as?

Answer 3

This acts as the actual “vault” to protect the DNA that is inside.

Question 4

DNA

Answer 4

The “instructions” for all cell’s activities, genetic material

Question 5

Chromatin phase

Answer 5

“The DNA is loose” (It would look like a bowl of plain spaghetti noodles.)

Question 6

Chromosome phase

Answer 6

“The DNA is tightly wrapped up.” (This phase is used for separating the DNA equally during cell division. This way we hopefully get two equal sets. One set for each cell.)

Question 7

Nucleolus

Answer 7

This structure acts like a photocopier in your school.

Question 8

What is the site of RNA synthesis?(“Synthe” means “to make”; “sis” means “the process of”) (This is the making a cheap, disposable copy of DNA.) (We can make “messenger” RNA, mRNA, and send it to the cytoplasmic “construction site”.)

Answer 8

Nucleolus

Question 9

What is the Nucleolus responsible for?

Answer 9

It is also responsible for helping to make Ribosomes, which are mostly RNA structures.
It also makes mRNA and other types of RNA molecules.

Question 10

These are membrane bound structures that have specialized functions that help it function efficiently.

Answer 10

Structure organelles
