Recommended: Importance of plants to humans

Plants plays a crucial role in the environment. They are the pillars of life on earth and is essential resource of every living organism. Plants provide humans the food for the survival, both direct and in indirect aspects. They serves as a resource for habitat not only for humans but for myriad species with different uses. And also, Oxygen is brought by plants, as a byproduct of photosynthesis through the different processes and cycle present in cell. Stomata is one of the part of cell that functions as a way that allow oxygen, carbon dioxide and water to move into and out of a leaf and It also facilitates the process of transpiration. This phenomenon occurs along with exchange of gases through this pores. As the gases get out through this pores they carry along with them water vapours. A stomata is a microscopic pore on the surface of plants. It is surrounded by a pair of specialized epidermal cells called guard cells, Guard cells are responsible for opening and closing the stoma. A number of environmental conditions will affect stomatal aperture (Zeiger et al., 1987). They are v...

  • Cellular Respiration And Photosynthesis Essay

    1028 Words  | 3 Pages

    Before learning about photosynthesis, I thought this was just a way for plants to grow, not knowing the full detail that goes on inside the plant for it to grow. So, after learning about what photosynthesis is and how it truly works, it is something that is remarkable and how plants are really the only living thing that uses this process. Photosynthesis is the process of taking in carbon dioxide (CO2), which is a gas that is exhaled from animals and goes into the air and is absorbed into a plant, water (H2O) which is absorbed through the roots of a plant or known as capillary action, sunlight is absorbed through chloroplasts which contain chlorophyll or better known as the leaves of the plant. With the photosynthesis process, the plant can create a by-product known as oxygen gas which is released through the little pores into the atmosphere (Simon, Dickey, Hogan & Reece, n.d.).

  • Photosynthesis Essay

    1372 Words  | 3 Pages

    In this laboratory experiment, the rate of photosynthesis was measured through the use of the “floating leaf disk technique.” The leaf disks were placed into a syringe and the O2 and CO2 in the mesophyll layers of the leaves were removed and then replaced with sodium bicarbonate or water, causing the leaves to sink to the bottom of the container. If one determines the number of leaf disks rising to the top as a result of an increase in oxygen gas in the mesophyll cells, then the rate of photosynthesis is able to be measured because O2 is a product of photosynthesis. The first step of this experiment was a feasibility study of the variance in the photosynthetic activity of the leaf disks in both water and bicarbonate solutions. After five minutes of light exposure, all of the leaf disks in the bicarbonate solution (10 disks) had ...

    ...hroughout the Eelgrass. Excess water in the form of vapor is disposed of through stomata on the leaves. The gas exchange, root, and shoot systems are used in this exchange because the stomata release the excess water in the form of water vapor, which was first absorbed by the roots in the root system, then transported through the xylem in the shoot system throughout the eelgrass. Another exchange that goes on in Eelgrass is nutrients to plant cells. Again the gas exchange, root, and shoot systems are used. Nutrients are absorbed by the roots and made through photosynthesis; stomata take in carbon dioxide which is used along with light, water, and other nutrients previously stored to make more. Nutrients are carried throughout the plant to plant cells by the phloem. Homeostasis is the balance of systems in organisms and it’s very important to keep them in balance.

  • Adaptation Of Plants

    657 Words  | 2 Pages

    The plants that we know today as terrestrial organisms were not always on land. The land plants of today can be linked back to aquatic organisms that existed millions of years ago. In fact, early fossil evidence shows that the earliest land plants could have arisen some 450 million years ago (Weng & Chappie 2010). Plants that used to reside strictly in water were able to adapt in ways that allowed them to move onto land. It is speculated the need for plants to move onto land was created by water drying up, causing plants to have less room and pushing them to move onto land. Although the exact cause of plant’s need to move to a terrestrial environment is unclear, it is known that plants had to undergo several adaptations to be able to live on land. These adaptations include: lignin, cellulose, suberin, and changes to plant’s surface, including the formation of a waxy cuticle.

    Photosynthesis occurs in the chloroplasts, using chlorophyll, the green pigment. It occurs in plant leaves, and little in stems. The leaf of the plant consists of the upper and lower epidermis, the mesophyll, the stomata and the veins. The epidermal cells do not contain chloroplasts, hence photosynthesis doesn’t occur there. They protect the rest of the leaf. The stomata are little holes, situated in the lower epidermis and are for air exchange, CO2 goes in and O2 out. The mesophyll cells have chloroplasts and photosynthesis occurs there. The chloroplast includes the outer and inner membranes, stroma, thylakoids of grana and intermem...

    Humans depend on plants in numerous ways. One reason we depend on plants is for consumption. Plants have the unique ability of producing their own food through a process called photosynthesis. In this process, plants are able to produce macromolecules such as carbohydrates that cannot be produced in animals or humans. In humans, the only to gain these macromolecules is to consume plant matter, or consume plant-eating animals (herbivores).

  • Transpiration Essay

    ... is exposed to sunlight, the light stimulates the opening of the stomata, hence speeding up that rate at which transpiration takes place. The opening and closing of the stomata occurs when the turgor in the guard cells, located over the stomata pores, changes. As guard cells take in water, minerals and ions from neighbouring cells, the osmotic and water potential is lowered. This makes water move into guard cells, consequently become more rigid. This then causes the stomata to open. If the guard cells could not extract water, minerals and ions from neighbouring cells, then the guard cells would not be turgid, resulting in the loss of water from the cells, hence closing the stomata. Although light is required for transpiration to take place, high concentrations are not required in order for transpiration to take place, unlike other processes such as photosynthesis.

    In a strict way, a community consists of all the organisms that live together in a particular habitat. Community structure concerns all possible ways in which the members of that community relate to and interact with each other. This includes the community-level properties that emerge from these interactions, such as trophic structure, energy flow, species diversity, relative abundance, and community stability [1].

  • Importance Of Trees Essay

    1136 Words  | 3 Pages

    Trees are one of the most important parts of the biosphere. They provide oxygen, which is one of the largest producers of life. Humans live and strive off of oxygen every second of their lives. Not just humans need oxygen to survive and thrive on Earth, but animals, and other creatures on the planet do as well. Trees are a huge part of all life and if they were gone, there would consequently be no form of life. Not only do trees create all forms of life, but they create beautiful surroundings for an area and create a comfortable and shady environment for all surrounding life. Even though trees seem to be everywhere you look, the planet is losing billions upon billions of them a year. Anywhere from three billion to six billion trees are lost every year, ("How Many Trees Are Cut Down Every Year? Rainforest Action Network Blog. N.p., n.d. Web. 10 Apr. 2014”). With this fact in thought, it shows that planting one tree can create a bigger difference than you realize.
