CELL TYPES AND STRUCTURES
OBJECTIVE
To observe the two main types of cells and their typical structure.
INTRUDUCTION
* PROKARYOTE:Any cellular organism that has no nuclear membrane, no organelles inthe cytoplasm except ribosomes, and has its genetic material in theform of single continuous strands forming coils or loops, characteristics of all organisms is the kingdom Monera, as the bacteria and blue-green algae. a cell lacking a true membrane-bound nucleus; * EUKARYOTE: is an organism with a complex cell or cells, in which the genetic material is organized into a membrane-bound nucleus or nuclei. * PROKARYOTIC CELL
PROKARYOTIC CELL
CHLOROPLAST: Chloroplasts are the food producers of the cell. The organelles are only found in plant cells and some protists such as algae. Animal cells do not have chloroplasts. Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells. * AMYLOPLAST: A nonpigmented organelle, or plastid, occurring in the cytoplasm of plant cells. Amyloplasts transform glucose, a simple sugar, into starch through the process of polymerization, and store starch grains within their stretched membranes. * CHROMOPLAST: Are plastids, other than chloroplasts, that produce and store pigments. Found in flowers, leaves, roots and ripe fruits, they contain carotenoids (lipid-soluble pigments ranging from yellow to red in color), which lend color to the plant tissues containing them. * STOMATA: Plants breath through tiny openings in leaves called stomata. Stomata open and close to allow the intake of carbon dioxide and the release of oxygen.
