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

contain chloroplasts‚ which convert the energy in light to chemical energy through photosynthesis. The cylindrical shape of palisade cells allows a large amount of light to be absorbed by the chloroplasts. Beneath the palisade mesophyll are the spongy mesophyll cells‚ irregularly-shaped cells that having many intercellular spaces to allow the passage of gases‚ such as the intake of carbon dioxide for photosynthesis to take place. The stomata is the way in which these gases are exchanged‚ as well as

Questions 1. Based on what you already know about photosynthesis‚ develop a testable hypothesis to explain the influence of an increase in light intensity on the photosynthetic rate in tomato leaves. 2. What is the relationship between an increase in light intensity and photosynthetic rate in tomato leaves? Does this relationship support the hypothesis that you formulated? As light intensity increases then the rate of photosynthesis increases linearly until a point is reached when the

of an additional phosphate group on the 2’ position of the ribose ring that carries the adenine moiety.In photosynthetic organisms‚ NADPH is produced by ferredoxin-NADP+ reductase in the last step of the electron chain of the light reactions of photosynthesis. It is used as reducing power for the biosynthetic reactions in the Calvin cycle to assimilate carbon dioxide. Synthesis The oxidative phase of the pentose phosphate pathway is a major source of NADPH in cells‚[1] and in cells without mitochondria

that help it carry out basic functions that are necessary to maintain life and proper photosynthesis. The first and outermost layer of tissue is called the dermal layer. This is the plant’s ‘skin’ and serves the plant mainly as a source of protection. Also present in the dermal layer of the leaves are stomata‚ which are tiny openings that allow carbon dioxide to enter and complete the Calvin Cycle of photosynthesis. The innermost layer of the plant is called the vascular tissue and is composed of phloem

GCSE Physics Coursework - Resistance of a Wire Coursework Resistance of a Wire Task To investigate how the resistance of a wire is affected by the length of the wire. Theory What is resistance? Electricity is conducted through a conductor‚ in this case wire‚ by means of free electrons. The number of free electrons depends on the material and more free electrons means a better conductor‚ i.e. it has less resistance. For example‚ gold has more free electrons than

The symbiotic relationship between plants and people is made possible by the differences between cellular respiration and photosynthesis. While cellular respiration occurs in all living organisms‚ photosynthesis relies on chlorophyll and is unique to plants‚ algae‚ and some bacteria. Respiration and photosynthesis are essentially the same process in reverse. During photosynthesis CO2 and H2O are converted to glucose and oxygen‚ while cellular respiration uses glucose and oxygen which are converted
