Unformatted text preview: s. Diatoms-->silica/protein and polysaccharide Euglena-->no cell wall EACH IS LINKED BY GLYCOSIDE BONDS, A TYPE OF COVALENT LINKAGE WHICH IS VERY STRONG; ADVANTAGE IS THAT CELLULOSE IS TOUGH --->GIVES RIGIDITY AND ABILITY TO WITHSTAND SALTS IN ENVMNT CHITIN: GLUCOSE WITH AMINO SUBSTITUTION ; FOUND IN CRAB SHELLS, ARTHROPODS. TOUGH POLYMER HAS ACETYL GROUP glucosamine N-acetyl glucosamine Algae: HAVE MEMBRANE BOUND CHLOROPLAST; SOME HAVE ACCESSORY PIGMENTS B/C; ALL HAVE A Chloroplast-> Chlorophyll a all (some have b & c) Carotenoids: xanthophylls & carotenes Phycobilliproteins: phycocyanin & phycoerythrin ALL HAVE Mitochondria--similar to plants and animals Nucleus-->(Eukaryon = Greek: Karyon = ‘kernal’ or ‘nut’) DNA with histone proteins/Diploid/Haploid MEMBRANE BOUND Gametes/Zygote--> new genetic combinations NUCLEUS SEGMENTED NUCLEI DNA STABILIZED WITH HISTONE PROTEINS ALGAE HAVE GROWTH CYCLES BUT HAVE A PATTER INDIVIDUAL IS DIPLOID, THEN GO THRU REDUCTION DIVISION AND BECOME HAPLOID; HUMANS HAVE SPECIALIZED TISSUE WHERE REDUCTION DIVISION TAKES PLACE. IN MO'S, THE ENTIRE CELL IS AFFECTED CYTOGAMY: CAN GO THRU CYT...
