energy of the Sun to produce usable forms of energy • photosynthesis- the process by which producers use solar energy to convert CO2 and water into glucose. • cellular respiration- the process by which cells convert glucose and oxygen into energy‚ carbon dioxide‚ and water. • Consumers/ Heterotrophs- An organism that must obtain its energy by consuming other organisms • primary consumers-an individual incapable of photosynthesis; must obtain energy by consuming other organisms

The carbon cycle shows how carbon is recycled -Carbon dioxide is taken in by plants in order to carry out photosynthesis and make food. -The carbon from the carbon dioxide is used to make carbohydrates‚ fats and proteins that make up the plant body. For example the cell wall of plants is made from cellulose - a carbohydrate. -Some of this carbon is returned into the atmosphere as carbon dioxide when the plant respires. When these plants are eaten by other animals this carbon becomes part

Light Dependent Reactions The light dependent reaction of photosynthesis involves the transfer of sunlight energy into two things: The production of ATP Reduction of coenzyme NADP to NADPH NADP – Nicotinamide adenine dinucleotide phosphate NADPH – Reduced NADP The energy from sunlight is used to excite an electron‚ within a primary pigment‚ to a higher energy level. The excited electron is then donated to an electron acceptor leaving the chlorophyll molecule oxidised and reducing the acceptor

consumers are very small‚ and they are easily contained in a liter of water. If you put these organisms in a bottle and turn on the lights‚ you get photosynthesis. If you turn off the lights‚ you turn off the primary production. Darkness has no effect on respiration. This is because cellular respiration is actually the reverse process of photosynthesis. Oxygen is a necessity of life requirements for basically all living organisms.* In this lab we are testing how different levels of salinity in the

and close to allow the absorption of carbon dioxide and release of oxygen. Photosynthesis is the process by which plants convert sunlight into suitable energy. (http://www.yourdictionary.com/photosynthesis) Photosynthesis actually takes place in the stomata where carbon dioxide and oxygen enter and leave the plant. Chlorophyll is the green pigment of leaves and plants that’s in charge of absorbing light for photosynthesis. (http://dictionary.reference.com/browse/chlorophyll) All chlorophyll plants

Stomata are tiny pores found on the epidermis of the leaf‚ surrounded by guard cells. [1] Their main function is gas exchange [1] for photosynthesis and respiration. The development of stomata on the leaves of a plant is determined by interaction between different genes and environmental factors. A few studies have been conducted in order to establish a relationship between stomatal densities and given environmental factors. Research has shown that stomatal densities are controlled by environmental

Autotrophic cells capture free energy through photosynthesis and chemosynthesis. Photosynthesis traps free energy present in sunlight that‚ in turn‚ is used to produce carbohydrates from carbon dioxide. Chemosynthesis captures energy present in inorganic chemicals. Cellular respiration and fermentation harvest free energy from sugars to produce free energy carriers‚ including ATP. The free energy available in sugars drives metabolic pathways in cells. Photosynthesis and respiration are interdependent processes

explores the question: Who is really domesticating whom? The Botany of Desire relates to the topic of photosynthesis. Pollan states that while humans were “learning to walk on two feet”‚ plants were “inventing photosynthesis and perfecting organic chemistry…” (xx). According to Pollan‚ a reason for the need for photosynthesis was immobility. Pollan explains that due to “perfecting” photosynthesis‚ plants were able to design chemicals for defense against predators‚ which then solved the problem of
