The Problem
Background of the Study A leaf is a lateral photosynthetic appendage of the stem of a plant, commonly broad, flat, thin and of a green color. Leaves (plural) are the “food factories of plants, the sites where most of the plant’s energy is produced [1]. There are leaves that provide a protective service when a plant is under attack. Leaves may also serve as a storage sites or help obtain food for a plant [2]. For plants, as defense, leaves protect them from enemies such as animals, diseases, and environmental extremes through specific defense mechanism [3]. The most important contributions leaves make to our planet’s ecosystem are through their processing of oxygen and carbon dioxide. Oxygen, though a waste product of photosynthesis is essential to plant, animal, and human survival. As leaves break down carbon dioxide and release oxygen, they also help determine global climate patterns [4]. On the other side, a block is a molded rectangular brick of clay or sand enclosed in a molder and hardened for long hours and used as a building and paving material. Bricks were often used for reasons of speed and economy [5]. The researchers aimed to make dry leaves into use not only by preserving it and use as decorations but by making it as one of the main component for concrete blocks. Also, to support the RA 9003 or known as Ecological Solid Waste Management Act for implement.

Objectives of the Study This study primarily aims to make dry leaves as one of the main component in making concrete

    Jane describes how the “day of the triffids” captured her attention as a child. The book described plants devouring humans although not occurring at this place and time insects do get devoured by plants. The master plan of plants is to reproduce so there can be more plants one way plants do this is to have fruit in hopes that an animal eats the fruit and then speeds the seed through their poop. Kids spread dandelions very unconsciously by picking them up and blowing the dandelions into the wind Jane Goodall makes a good point about this. In the case that these strategies do not work plants are also able to reproduce sexually and asexually, which helps with the plants master plan to spread their seed. This process can work in a way that is unconstructive as well. If the plant produces too rapidly it can clog water ways and lakes starving oxygen to water killing fish such as the water hyacinth. This adaptation of reproduction is not a defense to the predators. However plants have developed defense mechanisms such as poisons, sharpe needles and violates to protect themselves against predators. The plants can communicate with each other through their chemicals and the fungi in the root system. Plants showed the ability to react and remember in stress induced situations, such as animals with central nervous systems. The chapter ends with Jane Goodall and the loving relationship humans have had with plants throughout some of our time…

    Two important aspect that these plants would need to consider is the availability of water as well as the exposure to sunlight. In addition to phototropism, already discussed, plants have multiple ways that they can change their stimulus-response due to dehydration. Plants with only limited access to water may experience changes such as growing leaves with smaller surface area (less area for photosynthesis, but also less area for water loss), dropping of the larger lower leaves, and may also experience direct root growth into deeper soil for an increased water supply. Information about knowing where their predators would also be important as it would tell the plants that they need to execute a strong stimulus response that limits the potential danger. Thus heavy touches (heavy pressure) and other strong stimuli that indicate that predators are near would be reacted to by the plants. However, smaller constant stimuli, such as some mildly strong wind gusts and/or rain (depending on the plant’s native habitat), would probably be ignored as the plant may have also habituated to these frequent…

    Photosynthesis is a chemical process that converts the sunlight into a chemical energy that plants store for later. Without photosynthesis, the world as we know it would not exist. All the plants would die and so would a major food and oxygen source. During Photosynthesis water is sucked up through the roots up the stem and to the leaves. The leaves take in carbon dioxide and begin to absorb sunlight. these things combine to make glucose and oxygen. The plant then uses the glucose and oxygen is expelled through the stomata of the plant as a waste product. In The leaves there are a very special pigment called chlorophyll. Chlorophyll is responsible for the absorption of sunlight. Richard Martin Willstätter is the man responsible for studying these structures.…

    Studies are beginning to point to this shortage as potentially the cause for some of the increased “societal burdens of aggression, depression, and cardiovascular mortality” that we are witnessing. Leaves provide us with critical nutrients that are lacking in seeds. We as a society eat too much seeds which are high in starch and relatively high in calories, but we should be eating the leaves for their…

    Plant leaves are known to have a spongy mesophyll layer which usually contains CO2 and O2 gases within it, due to this leaves and leaf disks usually float in water. If leaves are placed in an alternate source of carbon dioxide in the form of bicarbonate ions, then photosynthesis can occur. When photosynthesis occurs, oxygen will accumulate in the air space of the mesophyll, causing the sunken leaf to become buoyant again. Cellular respiration occurs at the same time as photosynthesis in plant these, countering the processes and affecting the accumulation of oxygen in the air spaces. Therefore the buoyancy of leaf disks is an indirect measurement of the net rate of photosynthesis.…

    An experiment by Matos tested the phenotypic plasticity to light availability in shade and sun leaves of coffee trees (Matos et al., 2009). Their research indicated that "compared [to] sun leaves, shade leaves had a lower stomatal density, a thinner palisade mesophyll, a higher specific leaf area, and improved light capture…" (Matos et al., 2009). The sun leaves were described as "generally thicker with an enhanced quantity of palisade mesophyll" (Matos et al., 2009).…

    Every day we look at the trees, the ground, the flowers blooming, and we think of how brightly colored and blossomed they are. Not very many people think about how nature works or all of the different processes and cycles it goes through to give us the magnificent shades and hues all year round. One aspect of nature that people will often travel for just to see are leaves. Most people do not know what exactly the leaves go through to get to the beautiful colors they are, especially in the fall. Unless studying or reading about nature and leaves is a hobby of yours, then you probably do not know about all of the complex, scientific processes that they go through. If you are not familiar with all of the scientific terms and labels used when…
