Question

question 19
which of these is responsible for the
ough\ appearance of endoplasmic reticulum?
dna
enzymes
lysosomes
ribosomes

question 20
which cell structure modifies, shapes, and sorts proteins?
golgi apparatus
vacuoles
endoplasmic reticulum
nucleus

Explanation:

Analyze Question 19

Using the Organelle Functions knowledge point

• The rough endoplasmic reticulum (RER) is studded with ribosomes on its outer surface, giving it a bumpy or "rough" appearance under an electron microscope.
• Therefore, ribosomes are responsible for this characteristic appearance.

Analyze Question 20

Using the Organelle Functions knowledge point

• The Golgi apparatus is responsible for modifying, sorting, and packaging proteins received from the endoplasmic reticulum for secretion or delivery to other organelles.
• Therefore, the Golgi apparatus is the correct structure.

Answer:

Question 19

• DNA
• enzymes
• lysosomes
• ribosomes (Correct answer)

Question 20

• Golgi apparatus (Correct answer)
• Vacuoles
• Endoplasmic reticulum
• Nucleus
