Exam 2 Lab 7 Flashcards
What is a chromatid
one half of a replicated chromosome
2 main phases of cell cycle
Interphase
Mitosis
Phases of Interphase
G1
S
G2
Phases of Mitosis
Prophase
Metaphase
Anaphase
Telophase
What happens in G1
Growth phase
Organelles double
What happens in S
DNA synthesis
What happens in G2
Growth
New organelles
What happens in Prophase
Duplicated chromosomes have no particular arrangement in cell
Chromosomes condense
Spindle begins to form
What happens in Metaphase
Chromosomes line up at metaphase plate and spindle fibers attach
What happens in Anaphase
Sister chromatids are pulled apart and towards opposite sides
What happens in Telophase
2 Daughter cells are now forming
Spindle disappears
Nuclear envelope reforms
Similarities between plant and animal cell cycle
Chromosomes condense
Nuclear envelope breaks down
Chromosomes line up at Metaphase plate
Chromosomes are pulled to opposite sides of cell
Differences between plant and animal cell cycle
Animal cells have centrioles that organize spindles, plants dont
Plant cells cant furrow
Plants divide by cell plate
