âI think weâve read every single book they have.â Mark chuckled. He still wasnât ready to put the children downâWill was hanging off of one hip, his hand on Markâs shoulder as he stoically looked down at Bridget, and Mabel had nuzzled into the crook of Markâs neck with a contented sigh.
Diatoms are producers within the food chain. A unique feature of diatom cells is that they are enclosed within a cell wall made of silica (hydrated silicon dioxide) called a frustule. These frustules show a wide diversity in form, but are usually almost bilaterally symmetrical, hence the group name.
Diatoms are a protist (single cell organism) which is part of the family of eucaryotic (Cells that have nuclei) algae. There are two types of diatoms, pennales (pennate shaped), and centrales (circular shaped).Diatoms like all plant cells are photosynthetic, meaning they make their own sucrose (sugar) from light, water, and nutrients. Diatoms use oils to store sugar. The oil also keeps the diatoms afloat.here are two types of diatoms, pennales (pennate shaped), and centrales (circular shaped).
