ATP produces energy that helps the cell membrane that pump a membrane protein that pumps sodium ions out of a cell and potassium into the cell.

surface area of the leaf larger. The reason I think a higher light intensity could make the surface area larger is the fact that there would be a larger amount of chlorophyll‚ containing chloroplasts‚ for photosynthesis. By having leaves of a larger surface area‚ there would be a much more efficient use of the chloroplasts (containing chlorophyll) and the high intensity light available. Apparatus In order to carry out this experiment we will need: ·A light probe ·A graphing calculator ·A ruler Method

Analogy: baking a cake Step 1: gather the ingredients such as water‚ flour‚ baking powder‚ sugar and chocolate icing. The ingredients represent each products that the cycle of photosynthesis need. Such as water – which is use in the light dependent reaction when the molecules splits and gives off oxygen. Step 2: Preheat the oven at 375 degrees and that symbolizes the energy coming from the sun. Step 3: mix the flour‚ baking powder and sugar together. The Analogy for sugar is the electron coming

There are many differences between photosynthesis and cellular respiration. Photosynthesis requires energy as photons. Cellular respiration supplies energy in the form of ATP. In photosynthesis‚ electron transport occurs in the membranes of chloroplasts or thylakoid discs. Cellular respiration takes place in the membranes of mitochondria. In photosynthesis‚ water breaks down to supply 2 electrons and 2 Hydrogen ions and release ½ O at the beginning of the chain. In cellular respiration‚ 2 electrons

cycles to feed. I explained to him how plants use photosynthesis and respiration to produce sugars for food then releasing the used energy into our atmosphere. Four main factors needed to produce these processes are sunlight‚ oxygen‚ carbon dioxide‚ and water. I would explain to Van Helmont that under a microscope plants have cells that have tiny green pigments that contain chloroplast where all of the chemical reactions are computed. In photosynthesis a plant takes in carbon dioxide‚ water‚ and sunlight

is the third stage in cellular respiration and it occurs in the mitochondria. Photosynthesis: What is the overall goal of photosynthesis? - The purpose of photosynthesis is to produce energy for the plants to live on. Because photosynthesis only occurs in plants‚ why is it essential to animal life? - It works in a food chain. The animals eat the plants. If the plant doesn’t go through photosynthesis then the plant will die‚ eventually killing off all forms of life. What is the
