Question

select the part whose main job is to produce steroid hormones.
cell wall ribosome
mitochondria smooth endoplasmic
reticulum

Explanation:

To solve this, we analyze each option:

• Cell wall: Provides structure (plant cells), not hormone production.
• Ribosome: Synthesizes proteins, not steroid hormones.
• Mitochondria: Produces ATP (energy), not hormones.
• Smooth endoplasmic reticulum (SER): Involved in lipid (including steroid hormone) synthesis.

Answer:

smooth endoplasmic reticulum
