What is Chloroplast? – Structure, Function & Importance Explained Chloroplasts are one of the most essential organelles found in plant cells and some algae. These green structures play a key role in the process of photosynthesis, the method by which plants produce their own food. In this article, you’ll learn everything you need to know about chloroplasts—what they are, how they work, and why they matter in biology.  Definition of Chloroplast A chloroplast is a double-membraned organelle found in plant cells and eukaryotic algae that conducts photosynthesis . It contains the green pigment chlorophyll , which captures light energy to convert carbon dioxide and water into glucose (sugar) and oxygen .  Structure of Chloroplast Chloroplasts have a complex internal structure that is vital for their function. Here's a breakdown: 1. Outer Membrane Smooth and permeable to small molecules. Acts as a protective covering. 2. Inner Membrane Less permeable and cont...

Difference Between Heart Attack and Cardiac Arrest Causes of Heart Attack Signs and Symptoms of a Heart Attack Silent Heart Attack – What You Need to Know Risk Factors of Heart Attack Diagnosis of Heart Attack Treatment Options for Heart Attack Recovery After a Heart Attack How to Prevent Heart Attacks Conclusion Frequently Asked Questions (FAQs) What is a Heart Attack? A heart attack , medically known as myocardial infarction , occurs when the blood flow to a part of the heart muscle is blocked , often by a blood clot or plaque in the coronary arteries. This blockage deprives the heart of oxygen, causing damage or death to the heart tissue. It is a medical emergency and requires immediate attention to restore blood flow and minimize permanent damage. Difference Between Heart Attack and Cardiac Arrest Heart Attack =...

🌿 What is Transpiration Pull? Transpiration pull is a vital mechanism in plants that facilitates the upward movement of water from the roots to the leaves. This process is driven by the evaporation of water from the leaf surfaces, primarily through structures called stomata . 🧬 How Does Transpiration Pull Work? Water Absorption : Roots absorb water from the soil through osmosis. Cohesion and Adhesion : Water molecules stick together (cohesion) and to the walls of xylem vessels (adhesion), forming a continuous column. Evaporation : Water evaporates from the mesophyll cells into the air spaces within the leaf and exits through the stomata. Negative Pressure : The loss of water creates a negative pressure (tension) that pulls more water into the leaf from the xylem. Upward Movement : This tension pulls the continuous column of water upward from the roots through the xylem vessels to the leaves. This entire process is passive, relying on physical forces rather than ...
