produced from these substances during the process of photosynthesis in the presence of sunlight energy trapped by the chlorophyll. Humans depend on the already made food by plants since they can not make their own. Maize‚ rice‚ potatoes and vegetables are some of the plants eaten by human beings. Secondly‚ Plants remove carbon dioxide in the atmosphere which is a waste product of respiration in humans. They use this carbon dioxide in their photosynthesis process and produce oxygen which is a raw material

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

no growth. 2. How does increasing light intensity affect the rate of photosynthesis? Light intensity is a factor which can limit the rate of photosynthesis because if the light intensity is increased the rate of photosynthesis increases. However‚ at higher light intensities‚ the rate of photosynthesis will level off. 3. Describe the process of photorespiration. What is its effect on the rate of photosynthesis? Photorespiration is the process of combining PGA and glycolate to make

all examples of organisms in the kingdom fungi. The kingdom of the plants is the second largest kingdom. The plants are very complex multicellular organisms. They contain chlorophyll‚ which helps them prepare their own food by the process of photosynthesis in which plants convert energy from sunlight into food. This kingdom includes all types of plants like herbs‚ shrubs‚ trees‚ flowering and non flowering plants. The biggest kingdom is the kingdom of the animals. The animals are the most complex

Chloroplasts are the most important plastids found in plant cells. It is the structure in a green plant cell in which photosynthesis occurs. Chloroplast is one of the three types of plastids. The chloroplasts take part in the process of photosynthesis and it is of great biological importance. Animal cells do not have chloroplasts. All green plant take part in the process of photosynthesis which converts energy into sugars and the byproduct of the process is oxygen that all animals breathe. This process

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

Role of Stomata & Control Stomata : a pore found in the epidermis of plants which are used to control as exchange Main function of stomata : Allow enough C02 to enter the leaf to optimize photosynthesis‚ while conserving as much water as possible Structure of stomata * Each stomata consists of a stoma (minute pore) which are surrounded by 2 guard cells. * Stomata closes and opens according to the turgidity of the guard cells * Stomata also allows for cooling of the leaf by loss
