The rate of transpiration increases with temperature because warmer temperatures cause the stomata to open more widely, allowing for greater evaporation of water from the plant’s surface. Higher temperatures also increase the water-holding capacity of air, further promoting transpiration. Related Questions: Why is transpiration called a necessary evil? What is the composition of translocating fluid? … Read more
Gardeners use autumn leaves because they provide organic matter that enriches the soil. As the leaves decompose, they release nutrients like nitrogen, phosphorus, and potassium, which are essential for plant growth, and improve the soil’s structure and water retention capacity.

Transpiration is called a necessary evil because, although it leads to the loss of water from the plant, it is essential for the uptake of minerals and water through the roots and for cooling the plant. The composition of the translocating fluid, which flows through the phloem, primarily consists of water, dissolved sugars (mainly sucrose), … Read more

ATP (Adenosine Triphosphate) is a nucleotide consisting of adenine (a nitrogenous base), ribose (a five-carbon sugar), and three phosphate groups. The energy in ATP is stored in the bonds between the phosphate groups. When a cell needs energy, it breaks the bond between the second and third phosphate groups, releasing energy and converting ATP to … Read more
Aerobic respiration is the process by which cells generate energy in the presence of oxygen. It occurs in three main stages: Glycolysis: This occurs in the cytoplasm where one molecule of glucose is broken down into two molecules of pyruvate. This process produces a small amount of ATP and NADH. Krebs Cycle (Citric Acid Cycle): … Read more
An enzyme is a protein molecule that acts as a catalyst to speed up biochemical reactions without being consumed in the process. Enzymes are highly specific for their substrates, meaning each enzyme catalyzes only a particular reaction. They have an active site where the substrate binds, and the enzyme-substrate complex forms. Enzymes lower the activation … Read more
Anaerobic respiration and fermentation play significant roles in certain physiological conditions and in various industries. Anaerobic Respiration allows organisms to generate energy without oxygen, which is crucial during intense physical activities (e.g., when muscles lack sufficient oxygen). In human muscles, this process results in the production of lactic acid, which can lead to muscle fatigue … Read more
Comparison of Respiration and Photosynthesis Respiration and photosynthesis are complementary biochemical processes that sustain life. While photosynthesis captures energy from light to produce glucose and oxygen, respiration breaks down glucose to release energy in the form of ATP. Feature Photosynthesis Respiration Definition Process by which plants, algae, and some bacteria convert light energy into chemical … Read more
