Summary Of Proposed Research

Global drought not only affects the world agriculture and economics, but interactively affects the phenotypic trait of plants across a different diversity gradient. Nevertheless, plants are able to adapt themselves to the drought environment by changing their phenotypic trait. From previous research at Jena Drought Experiment, in Germany, the results show that diversity not only has the capability to increase community’s resistance to drought, but also to increase community’s recovery ability after drought. On the other hand, the results show that the drought environment makes a strong selection on both, the plant phylogeny and functional trait. Yet, ...

Introduction

Climate change is a major environmental problem, causing concern to various corners of our ecosystem. It is a result of global warming, environmental pollution and inefficient use of our natural resources. Climate change has affected almost all living organisms, including plants, animals, microorganisms and undoubtedly, man. It poses a serious threat to our ecosystem and is listed as a major concern in the Grand Challenges of the U.N. for Millennium Development and Millennium Ecosystem Assessment (Garrett 490). A wide variety of its implications, have made climate change, an important topic for researchers. There has been more awareness among researchers ...

1. How does the basic leaf structure suit its function? A leaf is a plant organ that is very crucial for a plant survival. It has a structure that makes it suitable to perform its functions. A leaf normally has a larger surface area so that they are able to absorb sunlight more easily. Sunlight is required by plants for the food making process. A leaf is normally very thin. This allows the carbon dioxide to travel and diffuse in a short distance. Also, oxygen which is usually a by-product, diffuse out easily. A leaf has a green coloring ...

Introduction

Stomata are sections in plants leaves that regulate the amount of water vapor and gases entering in and out of green plant leaves. Stomata are very essential in the control of water loss through the plant leaves in a process of transpiration. In light plants, transpiration is highest in the presence of sunlight because the guard cells fully open the stomata. Dark plants use the inverted stomatal rhythm and the openings of the stomata are wider in the dark. The opening of the stomata in leaves increases with time: at the beginning, fewer are open but after sometime majority become ...
