    are large cytoplasmic organelles.  Plastids are major organelles found in the cells of plants and algae. Plastids are the site of manufacture and storage of important chemical compounds used by the cell. Plastids often contain pigments used in photosynthesis‚ and the types of pigments present can change or determine the cell’s colour.  The term plastid was derived from the Greek word plastikas meaning formed or moulded.  This term was coined by Schimper in 1885.   In plants‚ plastids may differentiate

    Chapter 1 Revision Questions 1) List three abiotic characteristics and briefly describe the main differences between aquatic and terrestrial environments. Abiotic characteristics are: Temperature‚ Pressure and Light Availability. The differences between aquatic and terrestrial environments are: Small temperature changes occur in aquatic environments while large temperature changes occur in terrestrial environments. As the depth of water increases‚ pressure increases in aquatic environments while

Photosynthesis “deposits” energy‚ used carbon dioxide and water‚ and produces oxygen and glucose. By cellular contrast‚ cellular respiration “withdraws” energy‚ uses oxygen and glucose and produces carbon dioxide and water. b. The chemical energy of glucose

During this process mitosis has the function of permitting cells to replace ones that are worn out‚ damaged‚ or need to be replicated for single cells organism. Where mitosis is asexual cellular reproduction‚ meiosis not only multiplying the numbers of cells by cell division‚ but it reduces the number of chromosomes in each daughter cell to one-half of the number before meiosis (Pruitt and Underwood‚ 2006). Meiosis also permits chromosomes

    understanding around the rate of cellular respiration within multicellular organisms‚ also to research and understand how to use a CO2. Background: Living systems require free energy and matter to maintain order‚ to reproduce‚ and grow. Energy deficiencies cause disruptions at the population and ecosystem levels as well. 1 mol of H2O produces 1 mol of CO2 through cellular respiration. Autotrophic organisms capture free energy from the environment through the process of photosynthesis and chemosynthesis. Hypothesis:

    Cellular Respiration I/ Introduction - Cellular respiration is the cellular process whereby carbon-containing compounds are broken down through the series of reactions that result in the gradual release of energy. - Cellular respiration consumes oxygen (O2) and produces (CO2). Because oxygen is required so cellular respiration is aerobic. - Include metabolic pathways: glycolysis‚ transition reaction‚ the Krebs cycle‚ electron transport system and oxidative phosphorylation. - Overall reaction:
