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

Period G Interspecific and Intraspecific Plant Competition Abstract A study was conducted to address the problem of interspecific and intraspecific competition among wheat and mustard plants. It was hypothesized that increasing the plant density‚ and therefore increasing intraspecific competition‚ would negatively impact the plant biomass. It was also hypothesized that interspecific competition would have a stronger negative effect on the plant biomasses. This was tested by planting varying

Plants Desert Baobab Tree The baobab tree is the iconic tree of the African Sahara. It is readily recognized by its enormous trunk and‚ by comparison‚ scrawny stems and twigs. It is the source of many legends among the tribes of the area‚ and is also a rich source of traditional medicine. In a land where rainfall is limited and it is rare to find even tiny bushes‚ the gigantic baobab tree thrives. It is able to do so due to a number of unique adaptations that it has perfected over the course

Fast Plants By: Kinser Haselhuhn Biology 111 Section Y Professor Brittingham 4/19/13 Abstract: Introduction: Materials and Methods: To begin the fast plants experiment‚ each group received the F1 generation seeds for their designated phenotypes. After receiving the seeds‚ the seeds were then planted into Styrofoam “quads” allowing the seeds to germinate. The seeds were then allowed to grow under a fluorescent light bank for 5 weeks. Throughout the growing of the seeds‚ each plant
