“The Private Life of Plants: Traveling” was a useful documentary to help clarify my understanding on how plants manage to spread their seeds and germinate. I enjoyed watching the different time lapses for the species of plants and it helped me to see exactly what happens rather than reading it in a book or seeing a simple picture. I was amazed at all the different mechanisms plants used to travel around and not stick to just one area. I did not expect the pointy spines of plants to allow them to grip

surface of water and mud. Algae were evolving at the water’s edge‚ and one group – probably the charophytes – gave rise to plants. Cooksonia‚ a simple branching plant a few centimeters tall‚ evolved by 430 million years ago. It took another 160 million years for the taller Psilophyton to evolve. Then the evolutionary pace picked up. It took only 60 million years for plants radiate from the swampy lowlands to high mountains and nearly all places in between. They did so through modifications in

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

Fungal endophytes are found in asymptomatic photosynthetic tissues of all major lineages of land plants. The ubiquity of these cryptic symbionts is clear‚ but the scale of their diversity‚ host range‚ and geographic distributions are unknown. To explore the putative hyperdiversity of tropical leaf endophytes‚ we compared endophyte communities along

Plant Adaptation Investigation Observations Samples of plants were obtained during the campus tour. In order survive in the harsh climate of deserts‚ plants must adapt in function‚ reproduction‚ support‚ and defense. Although plants on campus are watered frequently‚ they live in a mostly xeric environment. Three types of cacti were observed: organ pipe‚ prickly pear‚ and saguaro. The organ pipe contains no leaves and has narrow stems that carry out photosynthesis and store water. Neither the

2011 Plants and Nitrogen Lab Report Introduction: Plants need ammonia‚ a combination of nitrogen and hydrogen‚ or nitrate‚ a form of inorganic nitrogen to grow. Most nitrogen is found in the atmosphere. However‚ plants and animals cannot directly absorb the nitrogen found in the atmosphere. Instead nitrogen gas is captured from the air by species of bacteria that lie in the water‚ soil‚ or grow on the roots of some plants. These bacteria convert the nitrogen into a form usable by plants. The

Plant cells are eukaryotic cells that differ in several key aspects from the cells of other eukaryotic organisms. Their distinctive features include: A large central vacuole‚ a water-filled volume enclosed by a membrane known as the tonoplast maintains the cell’s turgor‚ controls movement of molecules between the cytosol and sap‚ stores useful material and digests waste proteins and organelles. A cell wall composed of cellulose and hemicellulose‚ pectin and in many cases lignin‚ is secreted by

Abstract: Symbiosis is very important in the plant world. Fungus has a symbiotic relationship with other plants. This may help the plant through tough times‚ for example; droughts and long winters. There are many careers that study the problems of symbiotic plants. Symbiosis with Plants Symbiosis with plants is very important. Fungus helps the plant live through tough times. There is a lot of information available about symbiosis but there are also many unanswered questions. Certain careers
