path taken is: soil -> roots -> stems -> leaves The minerals (e.g.‚ K+‚ Ca2+) travel dissolved in the water (often accompanied by various organic molecules supplied by root cells).Less than 1% of the water reaching the leaves is used in photosynthesis and plant growth. Most of it is lost in transpiration. However‚ transpiration does serve two useful functions: * It provides the force for lifting the water up the stems. * It cools the leaves. Water and minerals enter the root by separate

materials both plants and animals take in to grow and prosper. Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar. This process occurs in plants and some algae. Plants need only light energy‚ CO2‚ and H2O to make sugar. The process of photosynthesis takes place in the chloroplasts‚ specifically using chlorophyll‚ the green pigment involved in photosynthesis. Photosynthesis takes place primarily in plant leaves‚ and little to none occurs

the cyanobacteria and the chloroplasts of algae and plants. Chlorophyll is an extremely important biomolecule critical in photosynthesis‚ allowing plants to absorb energy from lights. Chlorophyll is present in specialised cells within plants and many algae‚ when sunlight is present‚ chlorophyll combines it with water and carbon dioxide and creates energy through photosynthesis‚ a bi-product of which is oxygen. Organism that can photosynthesise are called autotrophs or “self-feeders”. Chlorophyll

currently consists of approximately 0.04% of Carbon dioxide. A large proportion of it is found dissolved in the oceans as well as the atmosphere. The carbon cycle consists of 6 stages. Initially the CO2 that is absorbed by plants for the use in photosynthesis becomes carbon compounds in plant tissue. The carbon is moved up the food chain by consumption‚ a primary consumer. It is passed on to the secondary and tertiary consumers when they eat other consumers. When these organisms die they are digested

have a starch level of 1 because the plant is missing CO2‚ which it needs to complete the photosynthesis process. 2. If the plant is in a closed environment‚ then the plant will have a starch level of 3 because it has all the environmental conditions it needs. 3. If the plant is kept in a dark environment‚ then it will have a starch level of 1 because it’s missing a fundamental resource needed for photosynthesis. 4. If the plant is kept in the presence of light‚air‚soil‚and water‚ then the plant will

Carbohydrates are used for numerous processes in organisms from acting in important roles of cellular recognition in the human body to storing chemical energy in plants in the form or starch. The roles of carbohydrates in the human body alone are numerous; providing energy for working muscles‚ providing energy for the regulation of blood glucose‚ preventing

Pigments are the substances that absorbed visible light. Different pigments absorb light of different wavelengths. From the absorption spectrum of chlorophyll a‚ it suggests that blue and red light work best for photosynthesis. There is a high degree correlation between the absorption spectra of leaf and the absorption spectra
