- spherical
- coccus
- rod shaped
- bacillus
- spiral shaped
- spirillum
- prokaryotic cell
- a prokaryotic cell is a cell which lacks a membrane bound nucleus or membrane-bound organelles; bacteria and cyanobacteria have prokaryotic cells
- eukaryotic cell
- A Eukaryotic cell is a cell which contains a nucleus surrounded by a membrane and membrane bound organelles (chloroplasts and mitochondria, for example); present in protists, fungi, plants and animals. The chromosomes of eukaryotic cells have proteins associated with the DNA and eukaryotic ribsomes are larger in size than those found in bacteria and cynobacteria
- autotroph
- an organism which uses chemical energy such as sunlight to make their own food, examples are plants, volvox, and diatomes
- heterotroph
- a heterotroph is an organism which cannot make its own food and must ingest energy containing molecules produced by other organisms. examples are animals, trypanasomes, amoeba proteus, forminiferans, parimecium
- photosynthesis equation
- carbon dioxide + water --(chlorophyll / sunlight energy)-->sugar + water+ oxygen
- cellular respiration
- cellular respiration is the chemical degradation of a sugar molecule in the presence of oxygen which produces chemical energy in the form of ATP. water and carbon dioxide are byproducts of theis process. cellular respiration occurs in all living organisms. whole organism respiration is the exchange of gasses between an organism and its environment.
- cellular respiration equation
- sugar + oxygen + water ---> carbon dioxide + water + energy (ATP)
- purpose of accessory photosynthetic pigments
- they capture light and transfer the energy to chlorophyll.each pigment has a different absorption spectrum, harvesting energy by utilizing different portions of the electromagnetic spectrum.
