Question

question 10
which of the following is not a component of the endomembrane system?
endoplasmic reticulum
golgi apparatus
nucleus
mitochondrion
lysosome

question 11
the process by which a cell engulfs a foreign particle is known as:
phagocytosis
endosymbiosis
membrane synthesis
hydrolysis
endofusion

question 12
which of the following is most likely to have the greatest concentration of rough endoplasmic reticulum?
a cell that engages in photosynthesis
a cell that destroys pathogens
a cell that secretes enzymes
a prokaryotic cell
a cell that makes steroid hormones

Explanation:

• For Question 10: The endomembrane system includes the endoplasmic reticulum, Golgi apparatus, nucleus, and lysosome. Mitochondria are not part of it as they have their own unique functions and double - membrane structure independent of the endomembrane system.
• For Question 11: Phagocytosis is the process by which a cell engulfs a foreign particle. Endosymbiosis is about the origin of some organelles, membrane synthesis is related to building cell membranes, hydrolysis is a chemical reaction involving water, and endofusion is not a standard term for this process.
• For Question 12: Rough endoplasmic reticulum is associated with protein synthesis. A cell that secretes enzymes (which are proteins) is most likely to have a high concentration of rough endoplasmic reticulum. Photosynthetic cells mainly have chloroplasts, cells that destroy pathogens may have more lysosomes, prokaryotic cells lack membrane - bound organelles like rough ER, and cells that make steroid hormones have more smooth endoplasmic reticulum.

Answer:

Question 10: D. mitochondrion
Question 11: A. phagocytosis
Question 12: C. a cell that secretes enzymes
