This lab is about Plant kingdom. As you know plants are all around us. This week students will study plants and their diversity. Plants are classified based on habit, habitat, presence or absence of vasculature, presence and absence of spores, naked seed or enclosed seeds, fruits and flowers.
Use the resources available to you and answer the following questions. You can visit a local arboretum, zoo or botanical garden to collect the information for the worksheet.

Mosses are common examples of seedless non-vascular plants. Identify a moss plant and answer the following questions based on your observations
a. Is the plant a sporophyte or gametophyte?
b. Does this plant have vasculature?
c. What is the function of vasculature?
d. What can you predict about the size of the plant based on answer to question B?
e. What other adaptations are essential for this plant to succeed?
f. Do you find true roots, leaves and stem in mosses?
g. How does reproduction take place in this plant (asexual or sexual)?
h. Picture of the plant (plants) and its scientific name.
