The Study of Ground Tissue, It essays

The Study of Ground Tissue, It essays In this lab I looked at different tissues of a plant in prepared and freshly prepared slides. Each of these slides showed the various tissues and cell types that make up a plant. I, specifically, looked at the angiosperm plants. I examined these plants by using the naked eye and drew diagrams describing the morphology of the plant. I, also, examined and drew diagrams of the anatomy of the plants by using a light microscope. I observed the ground, dermal, and vascular tissues and all their components. I observed them through the prepared slides and the freshly prepared slides, in which I had to cut a freehand section with a razor blade and stain with toluidine blue O to make. After I was finished with my observations I put away all of the equipment, cleaned my station and everything that needed to be cleaned, and threw away the materials that The purpose of this lab is to be able to identify the basic tissues and cell types, based on their appearance. In this lab I examined prepared slides of a typical dicot stem and sclerenchyma in a pear and a freshly prepared slide of apium graveolens (celery) stem. In these slides I observed ground tissue. The ground, or fundamental, tissue system includes three types of tissues: parenchyma, collenchyma, and sclerenchyma. Parenchyma cells are the most common of the ground tissues. They are found in the cortex of stems and roots, in the pith of stems, in leaf mesophyll, and in the flesh of fruits. There are even some strands of them in the vascular tissue. (Seagull 25) They are the least specialized of all plant cells and are often referred to as typical plant cells. At maturity they are alive and have primary walls that are relatively thin and flexible. Also, they are variable in size. They, mostly, lack secondary walls and the protoplast generally has a large central vacuole. They carry out most of the functions such as photo...
