Short note on Photosynthesis

Photosynthesis 

On earth, every organism needs food for its survival. Some animals eat plants as a source of food and some animals eat another organism as food. Similarly, plants also need food for their survival and they make their food on their own by taking sunlight as a source of energy and convert it into chemical energy. This process is called Photosynthesis. The word Photosynthesis is generally divided into two parts photo - light and synthesis - to make.


Things Need For Photosynthesis - For the photosynthesis reaction to occur there are generally three things to be needed -

• Water
• Carbon Di Oxide
• Oxygen
  

Process Of Photosynthesis - The process of photosynthesis generally happens in the leaves of the plant. The leaves of the plant contain chlorophyll in their cells which have one crucial pigment called Chloroplast. This Chloroplast is responsible for giving green color to the leaves of the plant. The process of plant photosynthesis is generally divided into two parts based on the requirement of sunlight.

• Light Dependent Reaction - As the name implies this reaction depends on light for their process. In this reaction, the light energy is converted into chemical energy as ATP & NADPH. This process occurs in the thylakoid membrane present inside Chloroplast.
• Light Independent Reaction - This reaction does not depend on light for their process. Therefore this reaction is also called a Dark Reaction. This reaction generally occurs in the stroma which is present outside of the thylakoid membrane of the Chloroplast. The final product is glucose results after the conversion of carbon Dioxide and another chemical compound.

Importance of Photosynthesis - Photosynthesis is a very important process that occurs in plants. There are following some importance of Photosynthesis -

• This process is very essential for making the balance in nature as plants take Carbon Di Oxide and in turn give Oxygen to us.
• All the products we get from plants like timber, fruit, resins, medicines are due to Photosynthesis.
• Due to this process plants are able to give food to other living organisms.
• Fruits are by-products of plants and Glucose is stored in them and provides a  source of energy to all living beings.

                              Characteristics of living beings

Welcome to this blog where we will explore the fascinating world of living beings and delve into the realm of Biology.

To begin with, let's understand the term "Biology." The word can be broken down into two parts - "Bio," which refers to life or living organisms, and "logy," which denotes the study of a particular subject. Therefore, Biology is the scientific study of living organisms, encompassing their physiology, anatomy, and distinctive features.

Living organisms possess certain characteristics that set them apart from non-living entities. These defining traits include:

Growth: Living organisms have the ability to grow internally. Unlike non-living objects that may grow externally, such as mountains with the accumulation of flora, living beings undergo internal growth and development.


Reproduction: Reproduction is a vital process for the continuation of species. Living organisms have the remarkable capacity to produce offspring of their own kind. Reproduction can occur through sexual means, involving the union of two sex cells, or asexual means, where a single parent gives birth to new organisms.


Metabolism: The totality of chemical reactions occurring within an organism is known as metabolism. It involves two essential processes: anabolism, which is the synthesis of substances, and catabolism, the breakdown of substances.


Movement: Living organisms exhibit the ability to move from one place to another. This unique characteristic distinguishes them from non-living entities.


Cellular Organization: Cells are fundamental building blocks of life. Living organisms possess a cellular structure with various shapes and sizes of cells, each serving specific functions in the body.


Responsiveness or Consciousness: A significant hallmark of life is responsiveness or consciousness. Living beings are aware of their surroundings and can react to stimuli. In contrast, non-living objects lack this capacity for conscious awareness.

By understanding these common characteristics of living beings, we gain valuable insights into the intricate world of Biology. Stay tuned for more fascinating topics related to the diverse and incredible life forms on our planet.
