prokaryotic cells plant cells animal cells
ribosomes
smooth endoplasmic reticulum
chloroplasts
submit

Explanation:

• Ribosomes: All cells (prokaryotic, plant, animal) need to synthesize proteins, and ribosomes are the site of protein synthesis.
• Smooth endoplasmic reticulum: Prokaryotic cells lack membrane - bound organelles. Plant and animal cells (eukaryotic) have smooth ER for functions like lipid synthesis.
• Chloroplasts: These are specific to plant cells (for photosynthesis). Prokaryotic and animal cells do not have them.

Answer:

• Ribosomes: Prokaryotic cells (✔), Plant cells (✔), Animal cells (✔)
• Smooth endoplasmic reticulum: Prokaryotic cells (✖), Plant cells (✔), Animal cells (✔)
• Chloroplasts: Prokaryotic cells (✖), Plant cells (✔), Animal cells (✖)
