Plant morphology

Abstract Photosynthesis, in essence, gives life to plants and plants give life to, us, humans. However, have you ever wondered how the first plant came to be? Through the process of an unlikely symbiotic union of an alga cell, a cyanobacterium, and a bacterial parasite and unfavorable environments, the first plant was born. Although scientists do not know why such a union occurred, they believe it might have to do with the theory of adaptation to one’s environment. Adaptation tends to occur when…

These plants only receive sunflecks, but it is believed that these provide up to 60% of the daily carbon gain by seedlings like Euphorbia forbesii and Claoxylon sandwicense. For photosynthesis to be at its optimum there should be on average of 16 hours of…

There are other elements within the text which suggest that the days in view are something other than simple days of standard length. The text suggests that the various creatures (plant and animal) came forth in a natural way at God’s instigation. Hence phrases like “Let the earth sprout vegetation” and “Let the earth bring forth,” as well as the emphasis on the ability of all life to reproduce via natural processes (e.g., “trees bearing fruit in which is their seed, each according to its kind”)…

may become groundwater (water that flows underground towards the nearest ocean)(name, date), it may continue to flow underground as run off until it reaches the ocean again. Plants release water into the atmosphere all the time through a process known as transpiration, during photosynthesis water release is higher. When plants absorb water through their roots, water vapor is released in the pores in their leaves in exchange for the intake of co2. This…

additional eight inches of rain fell but in a very short period of time. This amount of rain within such a short period of time resulted in a flood of unprecedented proportions for the South Carolina Botanical Garden. The devastation that occurred to the plants, animals, and grounds was of unfathomable proportions. The implausible amount of rain overwhelmed the Duck Pond and caused the water to breach the dam. The newly installed Natural Heritage Garden Trail received the brunt of the raging…

Research has shown that urine helps plants best when diluted with purified water; this is likely due to the fact that urine contains chemicals that would halt (or at the very least, slow down considerably) important processes within the plant. Such processes include, but are certainly not limited to, transpiration and photosynthesis, inarguably the two most vital activities performed within the plant. Transpiration occurs when plants lose water vapor through the guard cells and stomata;…

Plants and animals have made changes in their habitats as they have transitioned from water environments to land environments. This alteration requires the organisms to adapt to their new environments in order to survive and reproduce. These evolutionary transitions eventually led up to alterations in means of respiration, ways to prevent water loss, water dependent reproduction, and structural transformations. Amphibians evolved into reptiles and eventually into birds and mammals, being able to…

control group for two hours. The seeds in groups of three in 6” x 6” pots containing a doubly autoclaved mixture of field soil and potting mix at a 1:1 ratio. The maize plants were allowed to grow in 16 h light and 8 h dark at 28 °C ±2 in a greenhouse. Two least vigorous maize seedlings were eliminated to minimize the competition. The plants with five biological replicates for each treatment were put on randomized block design and watered every 1-2…
