the Importance of Photosynthesis-
All living creatures need food to survive and grow, and plants are no exception. Unlike human beings and animals, plants make their food called glucose (C6H12O6). Photosynthesis is by far the most important factor to a plants survival but do you know why it's important? Photosynthesis is the only reason why plants can survive, without it plants would not be able to create food and since plants are physically unable to hunt and eat all plants would eventually starve. Ever since a seed germinates into a sapling it is equipped ready for the plnt to create its own food to survive making photosynthesis a crucial chemical process to plants.
Energy transformations occurring in photosynthesis-
The sun is the primary energy source for many organisms living on the Earth. Plants use the energy they receive from the sun in order to fuel photosynthesis. In fact without radiant energy photosynthesis could not take place and life would not exist.The radiant energy from the sun along with carbon dioxide and water combines to make a new substance called glucose which indicates it is a chemical change because it is new and permanent. So the main energy transformation occurring in photosynthesis is a transformation of radiant energy to chemical energy.
Photosynthesis can be complicated but here is how I describe photosynthesis. First Carbon dioxide (the gas that we exhale) from the air passes through the stomata on the underside of the leaves. Then water is absorbed by the roots and passes through vessels in the stem on its way to the leaves. Next sunlight is absorbed by the chlorophyll located in the chloroplast of plant cells. It is this energy that is used to split water molecules into hydrogen and oxygen. Oxygen (the gas we breathe in) is then released from the stomata and ends up in our atmosphere while the Hydrogen and Carbon Dioxide that is still in the leaves are used to form glucose.Some of this glucose is used to provide energy for the growth and development of plants while the rest is stored in leaves, roots or fruits for later use by plants.
Products, Reactants, and Formula in Photosynthesis-
By know we should all be familiar with the process of photosynthesis but do you know the formula for photosynthesis? Well the formula for photosynthesis is 6CO2+6H2O+ radiant energy= C6H12O6+6O2 or in simpler turns carbon dioxide + water+ radiant energy= glucose + oxygen. You will notice that carbon dioxide and water are the reactants or in other words they are what start and continue a reaction or chemical change. Then you will notice that light/radiant energy is what fuels the reaction and finally you should see that glucose and oxygen are the products of the formula. The products in a formula is what is produced at the end of the reaction.
Chloroplasts are the source of almost all of the world's food and a lot of its oxygen supply, thanks to photosynthesis. They are the most important tool in photosynthesis and are found only in plant cells. What makes them so important is that they are the sites of photosynthesis and can perform tasks from absorbing radiant energy to the very important production of glucose. Chlorophyll located in the chloroplast is what gives plants their unique green color and their remarkable ability to provide for the cell.
Where Plants get Energy- Plants get their energy from the sun, a giant ball of hydrogen and helium 92.96 million miles away. Now you may be wondering how do plants get their energy from the sun well it all relies on chloroplasts. Plants produce glucose through photosynthesis which occurs in the chloroplast, this glucose is then used by the plant for energy, or stored as starch in the leaves for later use. The radiant energy from the sun, is then used by the plant to convert carbon dioxide and water into glucose.
Importance of Plants to Animals and Humans- Everything we eat in some ways comes from plants. Throughout history about 7,000 different plants have been used as food by people. Oxygen is brought to all humans and animals by plants as a byproduct of photosynthesis. In fact when the world was forming the whole atmosphere was mainly made of carbon dioxide but then plants formed causing carbon dioxide levels to go down and oxygen levels to go up. Plants store carbon, and have helped keep much of the carbon dioxide produced from the burning of fossil fuels and making of factory's out of the atmosphere. One-quarter of all prescription drugs come directly from plants. Also, four out of five people around the world rely on plants for health care. Lastly animals rely on plants for food as they are the most abundant food source meaning that they start off the food pyramid and keep it going.
Food chain- Plants are always located at the bottom of the food chain so without them all other consumers would die due to starvation. Anyway in a food chain, consumers are organized into three groups that include primary consumers, secondary consumers, and finally tertiary consumers. Primary consumers are mostly herbivores that feed on plants and fungus. Secondary consumers are mainly carnivores that prey on other animals. However omnivores can also be considered a secondary consumer. Tertiary consumers are usually known as apex predators (like lions and humans) and are usually found at the top of the food chain. Tertiary consumers can be either carnivorous or omnivorous. All in all plants provide the basis for all civilization on Earth.
