Level 9 Guided Question:How to plant uptake and use soil Nutrients?
As for all animals, your body is made of four types of tissue: epidermal, muscle, nerve, and connective tissues. Plants, too, are built of tissues, but not surprisingly, their very different lifestyles derive from different kinds of tissues. All three types of plant cells are found in most plant tissues. Three major types of plant tissues are dermal, ground, and vascular tissues
Level 9 - Investigation: Lab on Transpiration
Vascular plants are known as tracheophytes, which literally means “tube plants.” The earliest vascular plants quickly came to dominate terrestrial ecosystems. Why were they so successful? It was mainly because of their tube-like vascular tissues.The vascular tissues for which these plants are named are specialized to transport fluid. They consist of long, narrow cells arranged end-to-end, forming tubes. There are two different types of vascular tissues, called xylem and phloem.,Xylem is vascular tissue that transports water and dissolved minerals from roots to stems and leaves. This type of tissue consists of dead cells that lack end walls between adjacent cells. The side walls are thick and reinforced with lignin, which makes them stiff and water proof. Phloem is vascular tissue that transports food (sugar dissolved in water) from photosynthetic cells to other parts of the plant for growth or storage. This type of tissue consists of living cells that are separated by end walls with tiny perforations, or holes. Click on the button "Lab directions" to see how to the conduct the lab. Lab is worth

Level 9 elaborate:Plant Tissues
" Obtain three prepared microscope slides that contain the following plant specimens: stems,leaves and roots. Observe the size and shape of each cell it will give you clues to the type of tissues they are such as parenchyma, collenchyma or sclerenchyma. To know what to look for either read the online chapter on our text at the start of this page or do an internet image search or watch the VDO on "Plant Tissue" located above. Once you have located your image in the microscope either draw what you see watch you see being careful to make detailed drawings with color and label them with the specimen name as ell as he type or types of tissues you see click on the link below to download and print the lab
