Document Summary
Lecture outcomes 1: 2 roles of light as used by life. It is a source of energy that directly or indirectly sustains virtually all organisms. Light provides organisms with information about the physical world that surrounds them: characteristics of chlamydomonas that make it a useful model system. A single large chloroplast: to harvest light energy and to make energy-rich molecules through the process of photosynthesis. Eyespot: a light sensor; gather info about location and light source: function of basic components of chlamydomonas cells. Contains the cell"s dna (genetic information) in the form of genes. Consists of many interconnected membranous sacs called cisternae, onto whose external surface ribosomes are attached. Consists of many interconnected membranous sacs called cisternae (without ribosomes). The golgi apparatus modifies, sorts and packages macromolecules for delivery to other organelles or secretion from the cell via exocytosis production of energy by synthesis of atp. Chloroplasts are the sites of photosynthesis within plant cells.
