7 IMPORTANT FACTORS AFFECTING PHOTOSYNTHESIS

- by Jaishree Gorane - 9 Comments.

Photosynthesis is crucial for plant growth. Factors like light intensity, CO2 concentration, temperature, water, chlorophyll, protoplasm, and leaf structure affect and determine efficiency. Light intensity directly influences photosynthesis, while CO2 concentration initially enhances it. Temperature affects enzymes. Water scarcity hampers CO2 intake. Chlorophyll loss impairs energy absorption, protoplasm affects hydration and carbohydrates, and leaf structure determines light and CO2 entry.

What are the Adaptations of leaf for Photosynthesis

- by Jaishree Gorane - 7 Comments.

10 important leaf adaptations for photosynthesis. From a large surface area that captures abundant sunlight to the presence of chlorophyll and concentrated chloroplasts that optimise energy uptake, leaves have evolved to maximise the process. Efficient gas diffusion, thin leaves for rapid transport, transparent cuticle and an extensive vein system ensure the distribution of nutrients. Explore these vital adaptations for efficient photosynthesis.

Photosynthesis – Class 10

- by Jaishree Gorane - 19 Comments.

Photosynthesis, the vital process in plants, converts raw materials—carbon dioxide and water—into glucose, releasing oxygen. It occurs within chloroplasts, the site of photosynthesis. The process involves interconnected events, including light absorption, energy conversion, and carbon dioxide reduction. Factors like light intensity, temperature, and nutrient availability influence photosynthesis. Unique adaptations in desert and aquatic plants optimize their photosynthetic efficiency

13 Important Differences between Photosynthesis and Respiration

- by Jaishree Gorane - 8 Comments.

Differences between photosynthesis and respiration are significant. Photosynthesis is the process where plants convert sunlight, water, and carbon dioxide into glucose and release oxygen. It is light-dependent and anabolic, increasing plant weight. In contrast, respiration breaks down glucose using oxygen to release energy, carbon dioxide, and water. It occurs throughout day and night, is exothermic, and is essential for all organisms’ survival.

Types of Autotrophic Nutrition – Chemosynthesis and Photosynthesis

- by Jaishree Gorane - 5 Comments.

Autotrophic nutrition is of two main types – Chemosynthesis and Photosynthesis. Chemosynthesis involves the synthesis of carbohydrates using chemical nutrients as an energy source, while photosynthesis uses sunlight to convert carbon dioxide and water into glucose and oxygen. Chemosynthetic autotrophs thrive in low-light environments, while green plants, algae and cyanobacteria are particularly good at capturing solar energy through photosynthesis.

Autotrophic Nutrition – Significance ,Types, Organisms and Examples

- by Jaishree Gorane - 5 Comments.

Autotrophic nutrition, including photosynthesis and chemosynthesis, is of great significance for sustaining life on Earth. Autotrophs, such as plants, algae, and chemosynthetic bacteria, synthesise their own food. They play a vital role as producers, fixing carbon dioxide and forming the foundation of energy pyramids and food chains. Autotrophs fuel the development of ecosystems and provide essential nourishment for heterotrophs.

How are Fats Digested in our Body ? Where does this process take place?

- by Jaishree Gorane - 4 Comments.

Fat digestion takes place mainly in the small intestine, where large globules are emulsified by the bile of the liver. Pancreatic lipase further breaks down the globules into absorbable molecules. The digestive juices in the small intestine convert these molecules into fatty acids and glycerol. This complicated process ensures efficient fat digestion and takes place in coordination between the liver, gallbladder, pancreas and small intestine.

How is the Small Intestine designed to absorb Digested Food ?

- by Jaishree Gorane - 7 Comments.

The small intestine, a vital component of the digestive system, has a remarkable design optimised for efficient absorption of digested food. With millions of finger-like projections called villi, the inner surface area of the small intestine is significantly increased, facilitating nutrient absorption. This intricate structure, combined with the secretion of intestinal juices and specialised epithelial cells, ensures effective extraction of important nutrients from the food we consume.
