Its name is derived from the Greek words chloros‚ meaning ‘green’ and phyllon meaning ‘leaf’. First isolated

1. Answer the questions on slide 2 What are macronutrients? • Macronutrients are nutrients that come in large amounts. They include water‚ carbohydrates‚ proteins‚ and fats. What are micronutrients? • Micronutrients are nutrients that come in small amounts. They include minerals and vitamins. How are minerals defined? What functions do they play? • Minerals are essential for the function of our cells. They are inorganic because they don’t contain any carbon. Minerals help your muscles‚ bones‚ blood

hence an energy source‚ for many living creatures‚ making them essential in the food chain. 3. Describe the purpose‚ process‚ and chemical and energy components of photosynthesis and the source of each component (e.g. CO2 is found in the air)? Chloroplast cells in the palisaide mesophyll absorbs light‚ which is then transferred to the reaction center. Carbon dioxide in the air and water from within the plant combine‚ transferring electrons from water into carbon dioxide molecules in a process called

trans regions of the organelle. What is the difference between a primary and secondary lysosome? What is the function of a lysosome? Explain the structures of mitochondria and chloroplasts. What are the unique features of these organelles that have given rise to the theory of endosymbiosis? What class of organelles do chloroplasts belong to? What are some other examples from this class? Why are vacuoles so important for a plant or protist cell? What do plants and what do protists use the vacuole
Premium Cell membrane Protein Signal transduction
Chloroplasts are organelles composed of a phospholipid inner and outer membrane. Between these 2 membranes is an intramembranous space. Inside the inner membrane is a fluid called the stroma which contains thylakoids‚ where photosynthesis takes place. The

What is Life? This perennial question the answer to which has somehow eluded the most brilliant minds. For while scientists have identified many years ago the right mix of the atoms and molecules that constitute cellular material‚ they have not succeeded in ‘switching it on’ to make it alive‚ or ‘breathing life’ into it (Rabago et.al‚2006) In this module you will: a. Explain the concepts of the cell theory b. Identify the parts of a cell c. Describe the function of each cell part d. Differentiate

1) Submitted to: Lapridad Julieta D. Reyes‚ Ph.D. Instructor KINGDOM MONERA The members of the Kingdom Monera are prokaryotes and Some are the most primitive type of all cell to have evolved on earth. They lack organelles such as nucleus‚ chloroplasts‚ mitochondria‚ endoplasmic reticulum‚ golgi bodies‚ and lysosomes. Cell wall contains peptidoglycan composed of sugar linked by amino acids. They have a single circular chromosome located in a nucleoid. The main chromosomes consists of circular

large surface area. The space enclosed by the inner membrane is called the matrix‚ and contains small circular strands of DNA. The inner membrane is studded with stalked particles‚ which are the site of ATP synthesis. Chloroplast. Bigger and fatter than mitochondria‚ chloroplasts are where photosynthesis takes place‚ so are only found in photosynthetic organisms (plants and algae).
