Photosynthesis
What is photosynthesis in its simplest form?
Plants provide us with food.Ever wonder how plants get their food?
Plants make their own food.Water and salt are absorbed through the roots. Plants make food using all this in the leaves.Sunlight and chlorophyll, which gives green color to leaves, help make food.Photosynthesis is the process by which plants absorb water and salts through their roots and produce food in their leaves in the presence of sunlight.
Plants release oxygen during photosynthesis.This oxygen is breathed by humans and other living organisms.Carbon dioxide released by humans is absorbed by plants and used to make food.Thus, plants play a major role in sustaining human life.As the trees are cut down in mass, the oxygen level decreases drastically.
Steps of photosynthesis
1. Leaves contain chlorophyll, which helps plants make food.
2. Xylem is where water is absorbed and transported to the leaves.
3. Carbon dioxide is absorbed from the air through the stomata at the base of the leaf.
4. The energy required for photosynthesis comes from sunlight.
5. Carbon dioxide, water, green matter and sunlight required for photosynthesis all react in plant cells.
6. Thus producing oxygen needed by humans and food needed by plants.
7. The food thus produced is transported to other parts of the plant through the phloem.
8. Plants use this food when needed.
The Astonishing Power of Leaves and the Nature that Inspires Us
What is a leaf?
Leaves are green and they can be found on trees. There are also different colored leaves.The leaves are generally green in color.They do not have roots or flowers, but they have a stem that is called a petiole.
Leaves provide the tree with food through the process of photosynthesis, which takes place in the leaf’s chloroplasts.
Each leaf has two sides: one side that faces up towards the sunlight and one side that faces down towards the ground. This means that there are two different types of leaves: an upper surface and a lower surface leaf.
What are Leaves, Why Do We Take Them for Granted?
Leaves are a vital part of the ecosystem. They provide food for animals, help in the process of photosynthesis and serve as an indicator to climate changes.The leaves fall down and lie there to decompose and provide the conditions for the plants to grow.
What is the Meaning Behind Fall Colors?
The fall colors are the result of a process called "chilling" or "senescence." This process is triggered by shorter days and cooler temperatures. The leaves on the trees begin to change color when they lose chlorophyll, which is what gives them their green color.
Chlorophyll is a chemical that helps plants make food from sunlight through photosynthesis. As sunlight fades and temperatures drop, plants stop producing chlorophyll and other pigments that give leaves their green hue.
The Value of Fallen Leaves & Trees in Urban Areas
Fallen leaves and trees are often overlooked in urban areas. They are seen as a nuisance and a hindrance. However, they provide many benefits to the urban environment.
Fallen leaves and trees have been shown to improve air quality by absorbing carbon dioxide and other gases emitted from cars, buses, factories, etc. They also provide habitats for insects, birds, mammals and other wildlife. They help to reduce noise pollution because they dampen sound waves.
Why Leaves Change Color with the Seasons?
The leaves change color with the seasons because of the photoperiod. This is a term that describes the amount of light that a plant receives. When there is less light, such as during winter, trees produce less chlorophyll and their leaves turn brown or yellow. When there is more light, such as during summer, trees produce more chlorophyll and their leaves turn green.
What is Sap & What Does Sap Do?
Sap is a term used for the fluid that is produced by trees. It is also the name of a company that uses this fluid to produce products like paper, plastic and adhesives.
The sap is collected by tapping into the tree. The sap flows out of the tree, and it can be collected in buckets or other containers. Sap can also be collected from several trees at once with a machine called a "sap-line."
Types of Sap:
Tree Sap: Tree sap is often used as an ingredient in home remedies and cosmetics because it has anti-inflammatory properties.
Syrup: Syrup made from sugar cane or sugar beet juice often contains tree sap as well as corn syrup, water and additional flavors like vanilla or maple syrup.
