A less rigid structure: water pressure supports them. 5. Flat leaves on surface plants for flotation. 6. Air sacs for flotation. 7. Smaller roots: water can diffuse directly into leaves. 8. Feathery roots: no need to support the plant. 9. Specialized roots able to take in oxygen. Floating All floating plants

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 from the soil

for plant growth as well as crop physiology. Almost every plant process is affected directly or indirectly by water supply. Plants‚ as one of basic food sources‚ either in nature or cultivations‚ in their growing period‚ require water or at least moisture for germination. Certainly‚ most land plants are exposed to short or long term water stress at some times in their life cycle and have tended to develop some adaptive mechanisms for adapting to changing environmental conditions. Some plants may

Some of the most bizarre and fascinating plants in the natural world are undoubtedly carnivorous plants. Carnivory‚ defined as the consumption of animal tissue‚ is often only associated with the animal kingdom. However the existence of carnivory is widespread and diverse in the plant and fungi kingdoms as well. Specifically carnivorous plants‚ which originally descended from exclusively photosynthetic plants‚ have evolved elaborate‚ efficient‚ and diverse methods to capture‚ digest‚ and metabolize

Fast Plants Material and Methods When first preparing our fast plants we had to set up four different systems that would dictate our variable of fluorescent light. Each system would provide light to our fast plants for different amounts of time per day. Our systems were set up for 0 hours of light‚ 6 hours of light‚ 12 hours of light‚ and 24 hours of light. To setup the lab we began to setup our lighting system with fluorescent a timer for each set of fast plants. Our 24 hours was set up in

Chun Wai Discuss the advantages and disadvantages for plants of living in an aqueous environment compared to a terrestrial one? Introduction: Plants are commonly classified to two main types: aquatic plant and land plant. They have different features to adapt the living environment. What by meant is that they require different adaptions to stay alive in their respective environment such as humidity and structure of leaves. Aquatic plants referred to as hydrophytes or macrophytes. They need a special
