Diatoms

Vedclass · Answer

(A) In $Diatoms$, the cell wall is composed of two thin overlapping shells which fit together like a soap box. During asexual reproduction, the cell divides by binary fission. Each daughter cell receives one of the two parental valves (the larger epitheca or the smaller hypotheca). The daughter cell that receives the smaller hypotheca secretes a new, even smaller hypotheca to fit inside it. Consequently, the size of the cell decreases with each successive division until a critical minimum size is reached. At this point, the cell undergoes sexual reproduction to restore its original size.

The protist in which the cell size decreases with each division is $.......$.
