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

SICK PLANTS Hypothesis: From my research‚ I think the plant in the solution containing all nutrients will have the fastest / most successful growth‚ and the control group / water solution will have the least growth as it doesn’t have any of its necessary nutrients. Variables: The independent variable will be the solution the plants are put in to begin with. All other conditions will be kept the same‚ such as temperature‚ sunlight‚ length of shoot‚ time space left. I will have a control group

In contrast to mosses (Phylum Bryophyta)‚ the vascular plant sporophyte is dominant over AND is functionally independent of the gametophyte. • Conductive (vascular) tissues are universal AND are present in the sporophyte (not the gametophyte). • Although mosses live in moist environments (at least some of the time)‚ some vascular plants have acquired relative independence of free water. • Some vascular plants survive in harsh conditions (including hot and cool deserts). Ferns belong to the Phylum

after a week of measuring the biggest plant per bag. Each day the biggest radish plant in site A was measured and by day five the largest plant was 5 centimeters long‚ and had developed small green leaves. By the 5th day site B and D’s seeds showed no signs of growing and length remained at 0 centimeters. Site C and D’s superior seed both grew a total of 3 centimeters according to the 5th day measurements. Both the graph and table display the same results. The plants were measured with a ruler and then

Carnivorous Plants In a world where plants are at the bottom of the food-chain‚ some individual plant species have evolved ways to reverse the order we expect to find in nature. These insectivorous plants‚ as they are sometimes called‚ are the predators ‚ rather than the passive prey. Adaptations such as odiferous lures and trapping mechanisms have made it possible for these photosynthesizers to capture‚ chemically break-down and digest insect prey (and in some cases even small animals.) There

Plants and humans are perhaps the most important organisms‚ however‚ us humans‚ have caused the death of thousands of plants by starting fires and by cutting down trees for things such as paper and furniture. Plants make oxygen which is very important for our survival; we can’t live without it. In the year 2003 alone‚ 774500 acres of land‚ that contained not only threes but animals too‚ were burned in California (Jane Strong‚ 2003). Some of this land was burned due to natural fires but some of it

In 1976‚ the Rizal Cement company‚ owned by the Madrigal family‚ came under the management of PHINMA under a management contract with the owners. In 1978‚ General Luzon Cement (now Central Cement)‚ a company foreclosed by PCI Bank‚ was purchased by PHINMA. In 1983‚ an expansion plant for the Davao Union Cement was constructed.
