Question

Suppose you cut open a leaf in cross section and observed stomata on both the upper and underside of the leaf. As what would you classify this leaf?

Suppose you chop down a plant in the woods and bring it home to examine. You cut a cross-section of the stem and you note that it has pith in the center. How would you classify this plant?

You encounter a shrubby-looking plant that you cannot tell if it has true wood or not. Upon cutting it open cross-sectionally, you note a layer of cork cambium. What does this tell you??

Monocots and eudicots are so named due to differences in the number of leaves on the _______.?

What type of tissue comprises wood in woody stems??

In the forest, suppose you encounter a plant with large, broad leaves. Based on what you know about gymnosperm leaves and angiosperm leaves, what do you think this plant is??

Answer 1

1.When stomata present on both side of leaf the plant is called- AMPHISTOMATIC(also called oat type)

2. Since pith is present in the wooda the plant is a higher plant i.e.- VASCULAR PLANT

3. Presence of cork cambium means the plant has secondary growth and the plant is a woody or herbaceous plant. Secondary growth most of the time absent in monocots and the plant may be a dicot or a gymnosperm.

4. Monocots and eudicots are so named due to differences in the number of leaves on the- SEEDS(COTYLEDONARY LEAVES)

5. Wood ia primarily consist of secondary xylems, and the tissues include - trachieds, vessels and wood fibers.

6. Gymnosperm leavea are most of the time scale like or needle like and Angiosperm leavea are broad. So, the plant is an Angiosperm.
