Respiration in Plants Assignments/DPPs

The captivating journey through plant life takes a surprising turn with the chapter “Respiration in Plants” for Class 11, NEET and other medical entrance exams. It reveals that plants, often perceived as solely dependent on photosynthesis, also undergo a vital process called cellular respiration. This chapter equips you with a holistic understanding of how plants break down organic molecules to generate energy (ATP) for their survival and growth, just like animals do.

Overview : Respiration in Plants for Class 11 and NEET

While photosynthesis allows plants to capture energy from sunlight, it doesn’t paint the whole picture. Plants, like all living organisms, require a constant supply of energy for various cellular processes like growth, development, and nutrient transport. This energy comes from cellular respiration, a process that breaks down organic molecules (usually glucose) in the presence of oxygen to release energy (ATP).

The Biochemical Pathway: Breaking Down for Building Up

“Respiration in Plants” delves deeper into the intricate steps of cellular respiration:

Glycolysis: This initial phase occurs in the cytoplasm and doesn’t require oxygen. Here, glucose is broken down into a simpler molecule called pyruvate, with a net gain of a small amount of ATP.
Aerobic Respiration: This phase, dependent on oxygen, occurs within the mitochondria, the powerhouse of the cell. Pyruvate is further broken down through a series of reactions in the Krebs cycle (citric acid cycle) and the electron transport chain (ETC). These reactions generate most of the ATP produced during respiration.

The Players on the Stage: Organelles and Molecules

Understanding the key components involved in plant respiration is crucial:

Mitochondria: The organelles housing the enzymes responsible for the Krebs cycle and ETC.
Oxygen (O₂): Essential for aerobic respiration, acting as the final electron acceptor in the ETC.
Glucose (C₆H₁₂O₆): The primary organic molecule broken down for energy production.
ATP (adenosine triphosphate): The energy currency within cells, generated during both glycolysis and the ETC.
Carbon Dioxide (CO₂): A byproduct of respiration released into the atmosphere.

A Balancing Act: Respiration vs. Photosynthesis

While seemingly at odds, respiration and photosynthesis work together in a harmonious cycle:

Photosynthesis: Produces glucose (sugar) and releases oxygen as a byproduct.
Respiration: Utilizes glucose (sugar) and oxygen to generate ATP, releasing carbon dioxide as a byproduct.

Beyond Basics: Exploring the Significance of Respiration

“Respiration in Plants” highlights the far-reaching importance of this process:

Energy Production: Provides the essential energy for various plant functions like growth, nutrient uptake, and seed germination.
Heat Generation: Contributes to maintaining plant temperature, particularly in cold environments.
Germination and Seedling Growth: Provides energy for breaking down stored food reserves in seeds during germination and initial growth.
