4983633029	anaerobic	without air	1
5082939179	Tracheids	Specialized cells that conduct water in angiosperms	2
5082944781	Carpel	The female reproductive organ of a flower, consisting of an ovary, a stigma, and usually a style. It may occur singly or as one of a group	3
5082983454	Primary Structure	The first level of protein structure; the specific sequence of amino acids making up a polypeptide chain	4
5083010479	Secondary Structure	The second level of protein structure; the regular local patterns of coils or folds of a polypeptide chain	5
5083044557	Tertiary Structure	The third level of a protein structure; the overall, three-dimensional shape of a polypeptide due to interactions of the R groups of the amino acids making up the chain	6
5083093688	Quaternary Structure	The fourth level of a protein structure; the shape resulting from the association of two or more polypeptide subunits	7
5083152882	Carbohydrate	Member of the class of biological molecules consisting of monosaccharides, disaccharides, and polysaccharides	8
5083071721	Megaspore	the larger of the two kinds of spores produced by some ferns	9
5083181987	Estuary	the tidal mouth of a large river, where the tide meets the stream	10
5102451902	Polypeptide	A linear organic polymer consisting of a large number of amino-acid residues bonded together in a chain, forming part of a protein molecule.	11
5102715165	G1 phase	The cell grows physically larger, copies organelles, and makes the molecular building blocks it will need in later steps	12
5102722849	S Phase	The cell synthesizes a complete copy of the DNA in its nucleus and duplicates the centrosome	13
5102736377	G2 Phase	The cell grows more, makes proteins and organelles, and begins to reorganize its contents in preparation for mitosis.	14
5102760710	Cytokinesis	The cytoplasm of the cell is split in two, making two new cells	15
5102775876	Mitosis	The nuclear DNA of the cell condenses into visible chromosomes and is pulled apart by the mitotic spindle Four stages: prophase, metaphase, anaphase, and telophase.	16
5105521516	Glycolysis	Occurs in the cytoplasmic fluid of the the cell, that is, outside the organelles, begins respiration by breaking glucose into two molecules of a three-carbon compound called pyruvate	17
