Question

complete the chart by checking if the structure is found in prokaryotic eukaryotic (plant or animal) cells. some may have more than one check mark.
ribosome - synthesizes proteins
capsule - enables the cell to attach to surfaces
cell membrane - controls what enters and exits the cell
chloroplasts - site of photosynthesis
mitochondria - produce energy for the cell

Explanation:

• Ribosome: Present in prokaryotic (smaller 70S) and eukaryotic (larger 80S, in both animal and plant cells as protein - synthesis is a fundamental cellular process) cells.
• Capsule: Mainly a prokaryotic (e.g., bacterial) structure for attachment, not found in typical animal or plant (eukaryotic) cells in the way described (plant cells have cell walls but not capsules like prokaryotes).
• Cell membrane: Present in all cells (prokaryotic, animal, and plant). It is a universal cellular structure that controls the movement of substances in and out of the cell.
• Chloroplasts: Exclusive to plant (eukaryotic) cells as the site of photosynthesis. Animal cells and prokaryotic cells do not have chloroplasts.
• Mitochondria: Present in eukaryotic cells (both animal and plant) as the power - house of the cell, generating ATP. Prokaryotic cells lack mitochondria (they generate energy through other means like the cell membrane - associated electron transport chains).
