Question

comparing the cell to a factory \part of the factory goes inside the ( ) for each organelle\
the nucleus- (control center)
function:
____ cells ____ is contained in the nucleus, but in
____ cells ____ is located in the
______.
make up/ components- (p 249)
use the picture to the right to label each
part of the nucleus, and give its function,
and compare it to the factory.
a.
b.
c.
d.
______ carry the cells genetic information.

Explanation:

This problem is about cell structure and function, specifically the nucleus and genetic information. In eukaryotic cells, DNA is in the nucleus; in prokaryotic cells, it's in the nucleoid. Chromosomes carry genetic info. For nucleus components: A is nucleolus (makes ribosomes), B (if present, maybe nuclear envelope), C (nuclear pores, allow transport), D (chromatin, DNA + protein).

Answer:

• For the fill - in - blanks:
• Eukaryotic cells \(\boldsymbol{DNA}\) is contained in the nucleus, but in prokaryotic cells \(\boldsymbol{DNA}\) is located in the nucleoid.
• \(\boldsymbol{Chromosomes}\) carry the cell's genetic information.
• For nucleus components (assuming typical labels):
• A: Nucleolus - Function: Produces ribosomal subunits. Comparison to factory: Like a sub - unit production area.
• B: Nuclear Envelope - Function: Double - membrane structure that encloses the nucleus, regulating what enters and exits. Comparison to factory: Like the factory's main entrance/exit with security.
• C: Nuclear Pores - Function: Allow passage of molecules between nucleus and cytoplasm. Comparison to factory: Like doorways for materials.
• D: Chromatin - Function: Consists of DNA and proteins, packages DNA. Comparison to factory: Like the storage and organization system for blueprints (DNA).
