CHAPTER 7 LECTURE SLIDES Respiration • Organisms can be classified based on how they obtain energy: • Autotrophs – Able to produce their own organic molecules through photosynthesis • Heterotrophs – Live on organic compounds produced by other organisms • All organisms use cellular respiration to extract energy from organic molecules Cellular respiration • Digestion – enzymes breaking down large macromolecules into smaller ones. • Cellular respiration is a series of reactions

Patterns in Nature 1. Organisms are made of cells that have similar structural characteristics * Outline the historical development of the cell theory‚ in particular the contributions of Robert Hooke and Robert Brown Robert Hooke was the first person to observe a cell through a compound microscope in 1665. Franscesco Redi used a microscope to observe that flies do not spontaneously appear but develop from eggs laid by other flies. Many years later‚ Robert Brown observed a large body in

1. In some ways‚ chlorophyll can be thought of as a solar panel like the ones used to generate electricity at power plants. Using terms such as granum‚ photosystem‚ ATP and chlorophyll‚ explain this comparison. This comparison of a chlorophyll being thought of as a solar panel like the ones used to generate electricity at power plants can be explained as a chlorophyll would be the solar panel‚ a photosystem would be a specific arrangement of the panels‚ granum would be a stack of solar panels‚ and

Life cannot exist without energy Energy flows in one direction thru the ecosystem eg. Green plants (autotrophs) harness light energy from the sun. An another consumers eat the autotrophs and other consumers. This flow of energy is a consequence on the laws of thermodynamics‚ were in sense that energy can neither be stored or created‚ but is transferred from one type to another. At which sun is converted to heat. The transfer of energy in an ecosystem‚ can be showed in a number of ways eg as a

In this chapter‚ about photosynthesis‚ we vaguely learned about organisms that lived deep down in the ocean and they get their energy from earth. They make their own food‚ which makes them autotrophs‚ though they do this without the help of light (light independent process). Being fascinated about this process I did some research and tried to find out more about how they were discovered and what kind of environment they lived in; so I found a ted talk on this topic. In this Ted talk‚ Mike deGruy

Like cement sets the foundation for a house‚ the cell theory sets the foundation for biology. Schleiden and Schwann proposed the cell theory‚ which states that the cell is the basic unit of life and that new cells arise only from the reproduction of already existing cells via cell cycle‚ in 1839. Since the cell is the structural and functional unit of life as the house is for a community‚ without the house the community would be irritated and would not be stable‚ the community would therefore cease
