What are the features labeled A-D? Try and identify the plant stems. Are
these plants in growth position or have they been transported? How can you tell?
The scale bar = 3mm.
||Vascular tissue - phloem and xylem
||Hemispherical projection with
||Partially decayed cortex.
|Growth position or transported:
||These stems are most likely in growth position
because they all show the same alignment with very little cellular decay, and
not fragmentary. Also there are no fragments of other plant species and
very little detrital material present.
