We are at a point in the history of civilization where awareness of our fragile relationship to nature and the environment is high. We are losing 3‚000 acres of rain forest around the world and four species of plants and animals. More plants‚ insects‚ birds and animals became extinct in the 20th century than in any era since the Cretaceous catastrophe more than 65 million

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 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

A plants volatile organic compound (VOC) composition is the hand that swats unwanted visitors‚ welcomes visitation from much needed pollinators‚ and the substantial determinant in a plants identity and overall evolutionary fitness within the plant community. Understanding the mechanics of volatile formation is essential in interpreting their importance in plant life‚ and in plant-animal interactions. A huge allocation of energy is assumed to be given to the production of volatiles‚ and is therefore
