Question

question 7
peroxisomes got their name because hydrogen peroxide is:
produced during their oxidation reactions
a cofactor for the organelles enzymes
used in their detoxification reactions
used with ribosomes to produce proteins
incorporated into their membranes

question 8
in plant cells, the function of the lysosomes is carried out by ___.
peroxisomes
ribosomes
vacuoles
chloroplasts
nuclei

question 9
which of the following is both in eukaryotic and prokaryotic cells?
nucleus
mitochondrion
ribosomes
endoplasmic reticulum
vacuoles

Explanation:

• Question 7: Peroxisomes perform oxidation reactions that produce hydrogen peroxide, which is how they got their name.
• Question 8: In plant cells, vacuoles carry out functions similar to lysosomes in animal cells, such as waste - disposal and storage.
• Question 9: Ribosomes are present in both eukaryotic and prokaryotic cells. Prokaryotes lack membrane - bound organelles like the nucleus, mitochondria, endoplasmic reticulum, and large vacuoles found in eukaryotes.

Answer:

Question 7: produced during their oxidation reactions
Question 8: vacuoles
Question 9: ribosomes
