a schoo Chapter 35 The Plant Body 1. Describe and compare the three basic organs of vascular plants. Explain how these basic organs are interdependent. The three basic organs of a vascular plant are the stems‚ leaves‚ and roots. The stems consist of nodes‚ where leaves attach‚ and internodes between the nodes. The stem is responsible for elongation of the plant and acts as a central axis for other organs to attach to. The roots help to anchor the plant as well as absorb water and nutrients

Arrangement of Vascular Tissues in Flowering Plants • Xylem and phloem often are grouped together -> vascular bundle • Cambium -> lies in between xylem and phloem -> divide and differentiate -> form new xylem and phloem tissues -> thickening of stem Movement of Substances Into and Within Flowering Plants Entry of Water and Nutrients into Plants • Absorption of water -> root hairs -> grow into close contact with liquid around them • Thin film of liquid surrounding soil

Water is one of the most important molecules necessary to life. humans‚ for example‚ are made up of 70% water. Osmosis is a form of intracellular transport which is important in maintaining a correct balance of ions and substances between the blood and the inside of cells‚ for example. If the oncentration of an ion is too high outside a cell‚ water will br pulled out of the cell by osmosis in order to increase the water potential and thus retore balance. This is the case in ORT (oral rehydration

axes in a vascular plant. Fluids are transported between the roots and the shoots through the stem by the phloem and xylem. Leaves are the main photosynthetic organ of vascular plants. They have a fattened blade‚ a stalk and a petiole. They have the chloroplast (with chlorophyll) and the gas exchange takes place here. 2.) Intra-organism communication is possible through the xylem and the phloem. The transpiratinal pull is due to cohesion and adhesion. Evaporative cooling will result. A plant’s

Structure & Function of Plants Review: Plant Structure‚ Growth‚ and Development I 1. How does the vascular tissue system enable leaves and roots to function together in supporting growth and development of the whole plant? 2. When you eat the following‚ what plant structure are you consuming? Brussels sprouts‚ celery sticks‚ onions‚ and carrot sticks. 3. Characterize the role of each of the three tissue systems in a leaf. 4. Describe at least three specializations in plant organs and

Paramecium living in the intestines of termites breaks down the cellulose walls of wood fibers releasing proteins that are absorbed by the termites’ digestive system. Paramecium benefit by having an environment to thrive and they ingest the wood fibers for their own nutrition as well. 2. c. An important ecological effect
Premium Plant Algae Xylem
The evolution of plants has resulted in increasing levels of complexity‚ from the earliest algal mats‚ through bryophytes‚ lycopods‚ ferns to the complex gymnosperms and angiosperms of today. While the groups which appeared earlier continue to thrive‚ especially in the environments in which they evolved‚ each new grade of organisation has eventually become more "successful" than its predecessors by most measures. Probably an algal scum formed on land 1‚200 million years ago. In the Ordovician period
