Biology Quiz 10.1/10.2 Flashcards
Ratio of Surface Area to Volume
As the length of the sides increases, the volume increases more than the surface area
Formula
SA=6s2;V=s3
Surface area formula
Length x width x 6 sides
Volume formula
Length x width x height
Cell division
The process by which a cell divides into new daughter cells
Asexual reproduction
Production of genetically identical individuals from a single parent
Sexual reproduction
Involves the fusion of two parent cells offspring inherit some genetic information from each parent
Chromosomes
Genetic information is bundled into packages of DNA
Chromatin
Complex of chromosome and protein
Cell cycle
Cells go through a series of events as they grow and divide
What are the two cycles?
Prokaryotic cell cycle
Eukaryotic cell cycle
What are the 4 phases?
G1 phase-Cell Growth
S1 phase-DNA Replication
G2 phase-Preparing for Cell Division
M phase-Cell Division
Mitosis
The first stage of this process, division of the cell nucleus
Cytokinesis
The second stage,the cell division of the cytoplasm
Prophase
The first stage of mitosis
