that the stomatal density on high leafs is higher than on low leafs. During photosynthesis the chloroplasts in the leaf cells synthesize ATP from ADP as a result of exposure to light‚ while oxygen is produced as a by-product of the photosynthetic reaction. Carbon dioxide‚ which enters the plant through diffusion via the stomata‚ is needed for this process (photosynthesis) to occur. When the chloroplasts in the leafs cell is exposed to higher light intensities‚ more ATP is synthesized from ADP‚ while

combination of substances. The combination of substances often causes reactions‚ and one of the main groups of reactions is the single-replacement reaction. In Amrita University’s explanation of single replacement reactions‚ a single replacement reaction is defined as a “chemical reaction in which a more reactive element displaces a less reactive element from its compound.” The general formula for single displacement reaction is: AB + C A + BC. This formula shows element A being replaced in its

In light reactions‚ the goal is to transfer solar kinetic energy to chemical potential energy. This is first done by the absorption of a photon of light. Plant pigments are molecules that selectively absorb light energy at wavelengths. A pigment molecule absorbs a photon of light one of pigments electrons jumps to an energy level further than the nucleus. The electron has more potential energy here. The electron now has raised from the ground state to an excited state. Pigments of photosynthesis

Investigating the Limits of Cell Growth Background: To find factors that limit cell growth In multicellular organisms‚ In order for an organism to grow cells must divide through mitosis. Cell division happens after the cell is big enough so the daughter cells will be replicated without any flaws. The regulation and amount of materials that can enter and leave the cell is based on how large the cells surface area is. The rate of movement is also determined by the volume of the cell. Many factors like

Rates of a Reaction (Kinetics) KINETICS DESIGN LAB Research Question: Does the concentration of Potassium Iodide (KI) affect the rate of its reaction with hydrogen peroxide (H2O2) (of a fixed concentration)? Introduction: There are several factors that affect the rate of a reaction. Some of them being Pressure (if the reactants are Gases)‚ Temperature‚ Presence of a Catalyst‚ Surface Area of the reactant‚ and Concentration. According to the Collision Theory‚ during a reaction‚ particles

Investigating the Osmosis Effect in Potato Cores Aim The aim of this experiment is to investigate the osmosis effect in potato cores while they are submerged in different concentrations of sucrose solution. Osmosis will take place while the potatoes are fully submerged in the sucrose solution. Apparatus æ Scalpel (1) æ Tile (1) æ Pr.

Earth with the same acceleration as their space station. You could get the same situation on Earth if you were in a lift when the cable broke. True weight is equal to mg for whatever value g has at that location. Apparent weight is equal to the reaction force exerted on the object and is equal to mg + ma where ‘a’ is the upward acceleration of the object. (For an object accelerating down‚ a is negative) Students learn to “explain that a change in gravitational potential energy is related to

Bowens Reaction Series Mineral occurrence in igneous rock is most simply explained by Bowen’s reaction series. Norman Levi Bowen discovered the series of reactions while studying the process of crystallizing minerals in Washington‚ D.C. in 1928. In order to best express his findings to his scientific brethren‚ Bowen created a visual display based on when and under what conditions each silicate mineral crystallized. This is extremely important to geologists because it helps them to easily understand
