Role of mycorrhizas in the mineral nutrition of host plants Mycorrhizas are very important in the uptake of nutrients such as P‚ N‚ K‚ Cu‚ Zn and Ca by plants especially in soils low in these nutrients. Since P is the most limiting nutrient in tropical soils‚ mycorrhizas are vital for improving P nutrition particularly for cultivated plants. External hyphae can absorb and translocate P to the host from soil outside the root depletion zone. The thin mycorrhizal hyphae (2-4 μm in diameter) are able

Plant Hemoglobin Hemoglobin is a protein-iron compound found within the red blood cells of most vertebrates and is responsible for the cell’s red pigment. These red blood cells carries oxygen from the lungs to the rest of the tissue cells throughout the rest of the body. Just as hemoglobin transports oxygen in humans‚ they have also been found transporting oxygen within plants. In plants‚ there are two types of hemoglobin that can be found; symbiotic and non symbiotic. Oxygen is used

Aquatic plants: Fixed plants Fixed plants are held in place by their roots which grow in the water-bed. The Water Lily and Lotus are such plants. Their stems are long‚ hollow and light. These stems reach the surface of the water. The leaves and flowers‚ which grow from the top end of the stems‚ float upon the water. The leaves are broad with stomata on the top surface so that the water does not block them. Lotus The roots of lotus are planted in the soil of the pond or river bottom‚ while

Green plants absorb light energy using chlorophyll in their leaves. They use it to react carbon dioxide with water to make a sugar called glucose. The glucose is used in respiration‚ or converted into starch and stored. Oxygen is produced as a by-product. This process is called photosynthesis. Temperature‚ carbon dioxide concentration and light intensity are factors that can limit the rate of photosynthesis. Plants also need mineral ions‚ including nitrate and magnesium‚ for healthy growth. They
