Answer:
cell membrane
Explanation:
The cell membrane allows the cell to stay structurally intact in its water-based environment.
Reef-building corals were
confined to relatively shallow depths because
many of these corals have microscopic algae
called zooxanthellae living inside their soft tissues.
These algae
are often important for the corals’ nutrition and
growth, but require sunlight for photosynthesis. There is no sunlight deep in the water.
