Diatoms have cell walls composed of Silicon Dioxide.
Are you referring to land building (where when coral dies it contributes to reef) calcification (coral and other animals are calcifying due to pollution) or polyps (how coral grow)
Answer:
Red blood cells are considered cells, but they lack a nucleus, DNA, and organelles like the endoplasmic reticulum or mitochondria. Red blood cells cannot divide or replicate like other bodily cells. They cannot independently synthesize proteins,The nucleus is the cell's brain which controls much of its functions. An animal cell or eukaryotic cell will therefore die without a nucleus. The cell would not know what to do without a nucleus and there would be no cell division. The synthesis of proteins will either stop or shape wrong proteins.When red cells die, hemoglobin is broken up: iron is salvaged, transported to the bone marrow by proteins called transferrins, and used again in the production of new red blood cells

Blue whale is the biggest animal in the world
Penicillins disrupts bacterial cell wall synthesis.
<h3>
How does penicillin affect bacterial cell walls?</h3>
- Penicillin kills bacteria by inhibiting the proteins which cross-link peptidoglycans in the cell wall .
- When a bacterium divides in the presence of penicillin, it cannot fill in the “holes” left in its cell wall.
- β-Lactam antibiotics, including penicillins, cephalosporins, monobactams, and carbapenems, are distinguished by a lactam ring in their molecular structure and act by inhibiting the synthesis of the peptidoglycan layer of bacterial cell walls.
- Penicillins work by bursting the cell wall of bacteria. Drugs in the penicillin class work by indirectly bursting bacterial cell walls.
- They do this by acting directly on peptidoglycans, which play an essential structural role in bacterial cells.
