    The effect of different coloured lights on the rate of Photosynthesis Objective: To find out which colour of light provides the best consequences for the production of oxygen/ the rate of photosynthesis Background: In photosynthesis‚ there are two main parts‚ including light dependent and light-independent reactions. Plants use the energy from light for producing sugar‚ which is being converted into ATP by cellular respiration. They also are the only organisms that produce oxygen along with glucose

    Photosynthesis notes -sunlight brings energy to Earth -the energy in sunlight is packaged in photons -the photosystems in the thylakoid membrane capture photons -pigments in the photosystems have an antenna complex that actually grabs the photons -chlorophyll b captures the photons and transfers the energy to chlorophyll a (the reaction center) -when the reaction center receives the energy it donates an electron -the donated electron will move down the electron transport system (ETS) -ETS

    THE HEARTBEAT Heartbeats are needed to pump blood around our bodies. Heartbeats are initiated with electrical impulses which start out in Sino Atrial Node. The Sino Atrial Node sends its electrical impulse to the atrium when it detects that it is full as when the atrium is full it contracts and squeezes the blood in to the ventricles. In order for the ventricles to squeeze the blood out of the ventricles and in to the arteries so it can be pumped around the body‚ the electrical message from the

    The purpose of this experiment was to see if the different amounts of fertilizer we applied to the algae would affect the growth rate. Also‚ we tested if fertilizer was even an impact in the growth rate of algae. Increasing the amount of the dependent variable (fertilizer) would affect the independent variable (growth of algae) negatively due to too much chemicals that are being applied to the independent variable. Which would kill the algae cells or at last damage them and either the algae would

    different forms but no more may be added. So that these don’t run out they are cycles so they may be reused. Photosynthesis and respiration are the reverse of each other‚ and you couldn’t have one without the other. Carbon is an essential component of all organic substances‚ necessary in nucleic acids‚ proteins‚ carbohydrates. The only way that can enter ecosystems is when it’s used for photosynthesis. Carbon dioxide diffuses into the plants stomata and through the Calvin cycle is combined with other

    Biology lab: measuring the effect of light intensity on plant growth Aim: Investigate the effect of light intensity on plant growth Hypothesis: Light intensity will have an effect on plant growth. With an increase in light intensity there will be plant growth at a faster rate in comparison to when the light intensity is low where plant growth is limited and will take place slowly. When there’s too much light intensity‚ the light intensity will no longer become a limiting factor. A limiting

    1.) What is Biology? Biology is the science of life. Biologists study the structure‚ function‚ growth‚ origin‚ evolution and distribution of living organisms. There are generally considered to be at least nine “umbrella” fields of biology‚ each of which consists of multiple subfields. 2.) What are the branches of Biology? Describe each. Biochemistry: the study of the material substances that make up living things Botany: the study of plants‚ including agriculture Cellular biology: the study of the
