false
One of the functions of tracheids is extractive production
epithelial cell
What kind of cell do we find inside the dotted circle in the image below?
transverse
Which plane are you viewing in this photo?
false
Softwoods can have both longitudinal and radial (horizontal) epithelial cells.
While longitudinal epithelial cells can be found in softwoods, there is no such thing as a radial
(horizontal) epithelial cell.
fusiform
What kind of ray is shown in the image below?
true
Some species of softwoods don't have ray tracheids.
ray parenchyma
In the picture below, there are six rows of horizontal cells as indicated by the brackets on the
right. The middle bracket marks the middle four rows. The top and bottom brackets mark one
row each. What kind of cell occupies the middle four horizontal rows?
true
Softwood tracheid cells are dead at maturity.
true
Both ray tracheids and longitudinal tracheids have bordered pits.

Parenchyma have bordered pits.
false
In softwoods, longitudinal parenchyma are much longer than longitudinal tracheids.
ray tracheid
In the picture below, there are six rows of horizontal cells as indicated by the brackets on the
right. The middle bracket marks the middle four rows. The top and bottom brackets mark one
row each. What kind of cell occupies the top and bottom horizontal rows?
true
This is a heterocellular ray.
