Money, cars, televisions are things that people have but they think they “need” more. Most people overlook the smaller things that allow us to be able to acquire those things we so much desire that we think “need”. Plants give us many medicines, produce oxygen, and even help the environment by preserving the soil. Many plants that have been known with the right extracts were found by ancient civilizations. The extracts from plats help reduce aches and pain. Aspirin is actually found in the leaves of willows. Another example is the periwinkle plant that effectively fights leukemia. One-fourth of all prescriptions came from a plant. Vitamins come from plants too. Medicine is very important to us; essentially plants are vital to us. Besides allowing us to have medical research and medicines, plants also make oxygen. Obviously, we need oxygen to breath. Oxygen is a byproduct of photosynthesis. A necessity, breathing, of living comes from little things on the ground that we step on; that makes you think! Plants aren’t only vital to humans, they are the environment too. Plants help preserve soil by giving it nutrients. Especially in a forest or prairie, the roots of plants hold the soil together which reduces erosion. Even when plants die they decompose and make the soil richer. A plants job is never done! I have heard about photosynthesis and botany before, but I never realized how vital they are to me and the world. It’s hard to wrap your mind around the thought of
Dissolved Oxygen? Oxygen gas that is dissolved into water is dissolved oxygen, or DO. DO is essential for rivers, streams, lakes, and aquatic life. It is a positive sign to have DO in water. If there is an absence of oxygen in water, it can be a sign of severe pollution. Water ranges from very high levels of DO to very low levels of DO. Sometimes the DO is so low, there is hardly any aquatic life. Where Does Dissolved Oxygen Come From? Most DO in water comes from the atmosphere or plants. The…
Photosynthesis and cellular respiration are connected through an important relationship. The relationship between photosynthesis and cellular respiration enables life to survive as we know it. The exchange of oxygen and carbon dioxide through photosynthesis or cellular respiration helps keep the atmospheric oxygen and carbon dioxide at a stable level worldwide. The equation for cellular respiration is, Cellular Respiration: C 6 H 12 O 6 + 6O 2 → 6CO 2 + 6H2O. The series of arrows indicates that there are many…
Photosynthesis is a process used by plants and other organisms to convert light energy, normally from the Sun, into chemical energy that can be later released to fuel the organisms' activities. During photosynthesis there is a twostage process. The first step is to capture the Sun’s energy, which occurs in the leaves and other green parts of the plant, and once there pigments start absorbing the light; while the same time it gets CO2 through the surrounding air, which enters the plant by going into the stomata…
The plants which are in soil get their oxygen from the soil and they rely on the oxygen in the air to pass through the soil and then to the roots of the plant. This can sometimes result in lack of oxygen or low levels of oxygen. The plants in hydroponics get their oxygen from the air pump which delivers air to the reservoir, thus oxygen is constantly passed through the water and the plants would get more oxygen than when in soil, thus they would be able to utilize this more oxygen effectively…
temperature. In order to see how exactly different temperatures affect the rate, we can experiment with cotyledon plants. First, gather all the materials: 5 same size cotyledon plants, 5 clear closed containers to place the plants inside, and oxygen sensor to measure the rate of photosynthesis. Make sure to have 5 rooms with different temperatures but same amount of light and water for all plants. Control the temperatures in the rooms. Have one room be room temperature, one 10 degrees lower than the room…
Lauren Huntington Exam 1 Question 1 Imagine a life without photosynthesis? If you can’t, it’s because life would simply not exist without it. This process, which is the defining metabolism of all plants, evolved billions of years ago when early heterotrophic organisms were so abundant that the organic molecules they depended on for life were becoming scarce. Under the pressures of competition for nutrients, cells evolved that were able to make their own energy-rich molecules from inorganic materials…
which plants make sugar, which stores the energy from the sun into chemical energy. Respiration complements photosynthesis in that it converts the chemical energy made by photosynthesis into organic molecules that may be used by organisms. Two different experiments were performed to test the amount of oxygen gas present during photosynthesis and the rate of respiration of different sugars by yeast. In the first experiment we used an oxygen gas sensor, which measured the amount of oxygen gas made…
Extremely important we are your food source; given you are plant cells. The first and most important reason why you cannot fire us is because we are on basically on bottom of the food chain we make energy for the plants to survive. If you take out the ability for plants to make their own energy by firing us the Chloroplast, plants will no longer survive because our job is to turn the sunlight into energy for the plants to use to survive. Plants cannot just eat other organisms. An additional reason is…
within the bonds between molecules. The most common examples of chemical energy are fuels such as gasoline, coal, and natural gas Energy Energy is needed: •For blood circulation, lymph and tissue fluid throughout the body •Breathing and taking in oxygen •Making new cells for growth and repair •To transmit nerve impulses •To build enzymes and hormones produced after digestion Health & Social Care • Unit 5 Energy in the body The body needs energy to function. The process by which it gets this energy…
energy from the sun and use it to synthesize the molecules and cells of their bodies. These organisms are plants. The process that allow plants to capture the sun and use it for synthesis is photosynthesis. Because, in this way, plants make their own food, they are also called autotrophs. Auto means “self”, troph means “feeding”, so autotroph means “self-feeding”. In photosynthesis, plants take in simple inorganic compounds (CO2 & H2O) and build organic nutrients such as sugars (C6H12O6) 1…
