24
A meristematic tissue that increases the thickness of plant stems over time is the
(a) vascular cambium (b) apical meristem (c) pericycle (d) epidermal meristem.

Heartwood is older, darker xylem that
still functions slightly rapidly divides during growth season carries water to the leaves Stops transporting water completely

Final Question
49
Surrounding a vascular bundle
50
endodermis
51
Name two functions each for roots, stems, and leaves
53
What two types of wood make up the rings of a tree
What two types of wood make up the rings of a tree? What cause each type?(
54
Spring wood—wide gaps due to rapid growth
Late wood—narrow gaps due to mostly dormant cell growth.
55
What is the difference between a compound and a simple leaf
56
Simple leaf—one leaf from per petiole
Compound leaf—multiple leaves per petiole
