Patrick O’Donnell Science B2 Question: How does the presence of light affect the production and consumption of carbon dioxide in plants? The initial energy that lights gives to the chloroplasts ultimately affect the amount of carbon dioxide that is consumed and produced. To start the light dependent stage of photosynthesis, sunlight is needed for the initial energy in which the chlorophyll in the chloroplast harnesses. Water is taken in by the xylem tissues in the roots. The water molecules…

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…

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;…

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…

in an insect habitat has a significance in the determination of plant species in an area, which in turn determines which arthropod communities reside in it. Higher water content is a favorable condition for the majority of plants species that exist. Therefore, greater plant diversity is present in habitats surrounded by partially submerged in water. The results of an experiment conducted by Dinnage (2012) show that flourishing plant productivity provides a larger resource base for insects and…
