生物小常识（Biological knowledge） Outside the bilayer membrane, chloroplast grana stack up like cake, pigment, enzyme in cystic mass falling. Germinal layer differentiation: the outer surface echoes the sense of God, the inner layer calls out and the pancreas and liver, others originate from the mesoderm Mitotic period of importance: the shape of the equator is clear Essential amino acids: one or two, the pigment should have been weak Isoleucine, leucine, tryptophan, threonine, phenylalanine, lysine, egg (Jia Liu), amino acid, valine Basic laws of life substance: Water and inorganic salts form definite functions. Carbohydrates and lipids, cells, energy, species diversity, functions change. Nucleic acids, proteins, units are the key. The amino and carboxyl groups, dehydration peptide bond; phosphate base five carbon sugar, together constitute the nucleotide. Amino acid classification: Asparagus Valley, Lai Jing group, benzene, propylene, cheese, aromatics. A half bear two sides, dry cake shop without limit. [notes] the asparagus and the valleys are acidic, and the Lai, Jing, and the groups are alkaline. Benzene, orange, and cheese have benzene rings. Silk, Jiangsu, cysteine, asparagine, glutamine, egg polarity, Gansu, C, valine, isoleucine, proline, bright polarity Poppy chrysanthemum bindweed, papaya banana (lacticiferous vessel) Rhododendron, walnut, Sang Lan, Li Putao (endophytic mycorrhiza) 1, Chapter 1, the memory of cell membranes in the structure of cells Double leaf (mitochondria and chloroplasts double membrane) No sugar (no membrane structure is centrosome and ribosome) 2. Easily confused single celled organisms in prokaryotes and eukaryotes distinguish between memories Prokaryote: one (Yi Yuanti) branch (Mycoplasma), fine (bacterial) blue (blue-green algae) Eukaryotes: a (Yi Zao) group (algae), yeast (fungus), mildew (bacteria) The only organelle in prokaryotes: prokaryotes (prokaryotes) that have nuclei (ribosomes) 3, the role of mineral elements (N, P, K) The
