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…
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.

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 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…
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…

Photosynthesis is a sensitive process that responds in different ways depending on the environment and its changes. (Vargas and Cordero 2012). Recent studies have shown that there are many factors that affect the photosynthetic rate of plants. One study showed that the photosynthetic…
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…
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…
autotrophs is that heterotrophs (animals and fungi- e.g. Kangaroos) are organisms which cannot produce their own food so therefore must eat or ingest other organisms and autotroph (plants and cyanobacteria) are organisms that can make their own food.
Photosynthesis- carbon dioxide + water (light on chlorophyll) glucose + oxygen
Light reactions occur in the grana of chloroplasts where light energy is absorbed by chlorophyll driving a transfer of electrons to form energy molecules ATP and NADPH (formed…
Photosynthesis- carried out in the chloroplasts of plants; uses carbon dioxide to store
energy in the form of glucose (organic molecules); produces oxygen
6CO2 + 6 H2O
C6H12O6 + 6O2
Chloroplasts- found in the cells of green plants- convert light
energy into chemical energy, stores energy in food molecules.
Chloroplasts contain the pigment chlorophyll, which absorbs
mostly blue and red light, and reflects green and yellow (giving
plants their green appearance).
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)
