outline with two
semicells.
Semicells are ovate-pyramidal with a broad, flat base; the
lower angles are rounded, and the tip of the
semicell is truncate....
- halves,
called semicells.
Semicells are
diverse in shape, but are
unified by
having a single,
unbranched spine at the
angles of the
semicells. The cell wall...
- made of two,
symmetrical semicells. They are
usually longer than wide and are wavy and lobed. On the ends of the
semicells,
there is a notch. The cell...

divide into two
halves called semicells. The
cells are
typically 140–180 μm long and 65–85 μm wide.
Semicells have a pair of
basal lobes and a pair...
-
identical halves called semicells.
Cells are
about as
broad as long, 42–76 μm long and 40–72 μm wide
excluding the spines.
Semicells are
subelliptical to...
-
portions called semicells that are
almost entirely filled with chloroplasts, with a
nucleus that lies at the
center where the two
semicells are
joined together...
- with
blunt ends. Ring-like
thickening in the
central area
where the two
semicells join. In a good specimen, very
delightful to look at due to
obvious intracellular...

halves (termed
semicells), which, in a few
species of
Closterium and Penium, are of more than one...

semicells are not identical. In one
semicell, the
spines curve away from the isthmus,
while the
other semicell has
