Plants Organs As was noted in the previous chapter‚ most plant cells are specialized to a greater or lesser degree‚ and arranged together in tissues. A tissue can be simple or complex depending upon whether it is composed of one or more than one type of cell. Tissues are further arranged or combined into organs that carry out life functions of the organism. Plant organs include the leaf‚ stem‚ root‚ and reproductive structures. The first three are sometimes called the vegetative

The time of Jim Crow was a horrible time for the African-American population. The court case Plessy v. Ferguson ruled that segregation was okay as long as it is equal facilities (Pilgram‚ 2). This caused the laws of Jim Crow to take off and expand rapidly. Ben Tillman‚ the governor of South Carolina in 1892‚ said he would “willingly lead a mob in lynching a negro” (Klarman‚ 11). This demonstrates just how integrated segregation and racism was into southern society. In 1944‚ a Swedish man visiting

IB Biology HL Y1 15 January 2009 The Effect of Humidity on Transpiration in Plants Problem/Aim How does placing a plant in a more humid location for 50 minutes affect its rate of transpiration? Introduction Transpiration is the loss of water from a plant‚ mainly through the stomata of leaves. Darkness‚ internal water deficit‚ and extremes of temperature tend to close stomata and decrease transpiration; illumination‚ ample water supply‚ and optimum temperature cause stomata to open and increase

Biology Assignment Transpiration rates between Exotic vs. Native plants In this investigation we will be looking at transpiration. The topic we will be focusing on is transpiration rates between native plants as well as exotic plants. We will be experimenting with 2 native plants as well as 2 exotic plants. The reason we are experimenting on this topic is because of Australia’s dry weather‚ we are wanting to find out which plants will be able to hold more water during Australia’s peaking tempretures

The C4 & CAM Pathway Many plant species that evolved in hot‚ dry climates fix carbon through alternative pathways. Under hot and dry conditions‚ plants can rapidly lose water to the air through small pores called stomata. Stomata (singular‚ stoma)‚ are usually located on the undersurface of the leaves. Plants can reduce water loss by partially closing their stomata when the air is hot and dry. Stomata are the major passageways through which CO2 enters and O2 leaves a plant. When a plant’s stomata are

Mutualistic relationship of young desert plants and nurse plants. By: Anthony J. Johnston University of Arizona Abstract- The project being presented is on the association of desert plant life with nurse plants. It is said that desert plant life such as C. Gigantea‚ Ferocactus Wislizeni‚ and Ambrosia Deltoidea‚ associate themselves with other large nurse plants for protection‚ and other resources. Results showed that there was no random association of this hypothesis; therefore the null hypothesis
