Which of the following statements accurately compare the cross-sections of these two types of plants? Choose all that apply.
|
In monocots, xylem cells are larger in diameter than phloem cells, but the opposite is true for eudicots. |
||
|
Monocots have pith in the center and cortex near the stem surface; eudicots do not. |
||
|
Monocots have vascular bundles scattered in the stem; eudicots have theirs arranged in a ring around the outer part of the stem. |
||
|
Both stems have epidermal cells on the outside. |
||
|
The vascular bundles in both stem types are surrounded by ground tissue. |

The evolution of plants onto land required them to solve several problems. The first groups of plants to come up with an effective means of support on land was the Mosses Flowering plants Angiosperms Gymnosperms Ferns A unique characteristic of monocots is They have secondary growth They have no vascular tissue They have no netted leaf veins They have scattered vascular bundles They are flowering plants Osmosis is most important in the transport of Sugars in the phloem Sugars in...

3. Now examine a prepared slide of a Psilotren stem cross Section Notice the epidermis with its well-developed cuticle. Stomata are present here as well. The cortex is relatively large and has three regions. Beneath the epidermis is a region of parenchyma cells that contain chloroplasts (chlorenchyma). Adjacent to the chloren- chyma is typically a zone of sclerenchyma cells that give the stem support. The innermost portion of the cortex consists of another region of parenchyma...
