Group: Production, morphology, and arrangement of cells on stalks


10911027 Stalks are present.

10911001 Cells are borne on stalks.

10911002 Stalks are attached to one pole of the cell.

10911003 Stalks are attached in a subpolar position on the cell.

10911004 Stalks are attached to the side of the cell (other than subpolar).

10911005 The stalk is an extension of the cell wall.

10911006 Stalks develop at the flagellated end of a cell.

10911007 The stalk is a secretion of the cell.

10911008 One end of the stalk is attached to a substratum.

10911009 Holdfasts are produced.

10911010 The holdfast is located at the tip of the stalk.

10911011 The holdfast is produced on the cell at a point from the origin of the stalk.

10911012 Stalk (peduncle, pedicle) is very short, almost reduced to a simple holdfast.

10911013 Stalks are elongated.

10911028 Stalk is twice as long as body.

10911029 Stalk is stiff.

10911030 Stalk contains spasmoneme (contractile fiber).

10911031 Stalk is filamentous.

10911032 Pedicle is flexible.

10911014 Stalks are branched.

10911015 Stalks are dichotomously branched.

10911033 Stalk branches contract singly.

10911034 Stalk branches contract together.

10911016 Stalks are dumbbell-shaped in cross section.

10911017 Stalks are circular in cross section.

10911018 Stalks are ribbon-like.

10911019 Stalks are horn-shaped.

10911020 Stalks are lobate.

10911021 Stalks are slender.

10911022 Stalks are twisted.

10911023 Stalks contain ferric hydroxide.

10911024 Stalks are soluble in hydrochloric acid (HCl).

10911025 Cells are permanently attached to the stalks and in this state are nonmotile.

10911026 Motile daughter cells are liberated from the mother stalk cell.
