Draw and label a Pinus embryo as you saw it on the slide in lab this week. A tracheid is a structural and conductive cell in the xylem. Explain the meaning of the term gymnosperm. Apply the word dioecious to members of the genus Pinus . Dioecious means 2 houses so the genus Pinus is dioecious because the female and male pine cones are found on the same tree.
Long shoots form the axis for females and short shoots for males.
