Explanation:

• Question 10: The Golgi apparatus modifies, sorts, and packages cellular products (such as proteins) for secretion. Phagocytosis is mainly done by lysosomes, protein synthesis occurs in ribosomes (often attached to RER), and intracellular digestion is a function of lysosomes.
• Question 11: RER (Rough Endoplasmic Reticulum) has ribosomes attached and is involved in protein synthesis (so it can be involved in producing vesicles as proteins are packaged), intracellular transport (as proteins move through the RER network), and detoxification (though less common compared to SER in some cases). Synthesis of membrane phospholipids is mainly a function of SER (Smooth Endoplasmic Reticulum).
• Question 12: Lysosomes are formed by the Golgi apparatus. The Golgi modifies and packages enzymes into vesicles that become lysosomes. The nucleus contains genetic material, the cell membrane is a separate structure for protection and transport, and the endoplasmic reticulum is involved in protein and lipid synthesis.
• Question 13: The interconnected nature of RER and SER can facilitate the movement of phospholipids. For example, lipids synthesized in the SER can move to the RER (which is involved in protein - lipid interactions in membrane synthesis). Ribosome distribution is not facilitated by their interconnection in this way, steroid - producing enzymes moving from RER to SER is not a main function of their interconnection, and vesicle movement from ER to Golgi is a separate transport mechanism.
• Question 14: Assuming structure V is the ribosome - studded RER (but if V is the ribosomes themselves, ribosomes are made of rRNA and proteins. If it's a general organelle question, proteins are synthesized in RER (if V is RER). ATP is mainly synthesized in mitochondria, vesicles are formed by Golgi or ER budding, and ribosomes are complexes of rRNA and proteins (not synthesized as a whole in a typical organelle in this context).
• Question 15: The nucleolus (if W is the nucleolus) synthesizes the subunits of ribosomes. The nucleolus is involved in rRNA synthesis and ribosome subunit assembly. X (assuming it's ER), Y (assuming it's mitochondria), and Z (assuming it's Golgi) do not synthesize ribosome subunits.
