Question

question 2 (6 points)
match the cell parts to their function:
column a

1. ___ dna molecules
2. ___ protein molecules
3. ___ nucleus
4. ___ nuclear pores
5. ___ nuclear envelope / nuclear membrane
6. ___ nucleolus
7. ___ ribosomes

column b
a. provide directions for cells to follow
b. these are the main products of cells
c. this is a structure within the nucleus that produces ribosomes
d. these \holes\ on the nucleus allow molecules to enter and leave the nucleus
e. this is the outer barrier that surrounds the nucleus
f. this organelle stores the dna molecules and keeps them safe
g. these structures manufacture protein molecules according to genetic instructions from the nucleus

Explanation:

• DNA molecules carry genetic information which provides directions for cells to follow.
• Protein molecules are the main products of cells as they perform various functions in the cell.
• The nucleus stores the DNA molecules and keeps them safe.
• Nuclear pores (the "holes" on the nucleus) allow molecules to enter and leave the nucleus.
• The nuclear envelope / nuclear membrane is the outer barrier that surrounds the nucleus.
• The nucleolus is a structure within the nucleus that produces ribosomes.
• Ribosomes manufacture protein molecules according to genetic instructions from the nucleus.

Answer:

1. DNA Molecules - a. Provide directions for cells to follow
2. Protein Molecules - b. These are the main products of cells
3. Nucleus - f. This organelle stores the DNA molecules and keeps them safe
4. Nuclear Pores - d. These "holes" on the nucleus allow molecules to enter and leave the nucleus
5. Nuclear envelope / Nuclear membrane - e. This is the outer barrier that surrounds the nucleus
6. Nucleolus - c. This is a structure within the nucleus that produces ribosomes
7. Ribosomes - g. These structures manufacture protein molecules according to genetic instructions from the nucleus
