Question

explain why a lack ofsilica would interfere with diatom reproduction

Answer 1

Diatoms are unicellular organisms, which are covered with a cell wall containing silica, which is called frustule. These diatoms can exist in colonies, and form shapes like filaments, zigzag and stellated patterns, and ribbon-shaped colonies. Diatoms have a nucleus, cytoplasm, vacuoles, and chromatoplasts as cell components. The silicon wall is porous with different designs at various places for passage of gases and nutrients within the cell. The reproduction process can occur by either sexual or asexual reproduction. All diatoms pass through a seed-like or a spore phase called the resting spore.

Diatoms are dipoid, photosynthetic, single celled or colonial protist that secretes a protective silica shell. This silica rich material is used in filters and cleaners, and as insectiside. Lack of silica, can interfere with diatom reproduction.
