Cards

Term

 

SOMATIC

CELLS

Definition

Body Cells

Term

 

 

DIPLOID

Definition

Full set of genetic chromsomes

 

Term

 

 

MITOSIS

Definition

Occurs in somatic cells

Prodcues 2 identical daughter cells

ASEXUAL REPRODUCTION

Term

 

 

SEX CELLS

Definition

Sperm and egg

Term

 

 

HAPLOID

Definition

Half set of genetic chromosomes

23(sperm) + 23(egg) = 46 chromosomes

Term

 

 

Meiosis

Definition

Occurs in sex cells

Produces 4 NON-IDENTICAL GAMETES

SEXUAL REPRODUCTION

Term

 

 

I-PMAT

Definition

Interphase, Prophase, Metaphase, Anaphase, Telophase (Kinocytosis)

Term

 

 

INTERPHASE

Definition

Preperation before mitosis/meiosis 

 

Term

 

 

INTERPHASE:

G1 Phase (Gap Phase)

Definition

Manufactures protiens & amino acids

Cells grows

Term

 

 

INTERPHASE:

S Phase (Synthesis Phase)

Definition

DNA replicates

Longest stage of interphase 

Term

 

 

INTERPHASE:

G2 Phase (Gap Phase)

Definition

Prepares to divide

Same as G1 Phase 

Term

 

 

APOPTOSIS

Definition

Cell suicide

Occurs when cell runs out of DNA

Term

 

 

CHROMATIN

Definition

Complex long threads made of DNA and protein that makes up chromosomes 

Term

 

 

UNCONDENSED CHROMOSOME

Definition

Long, thin strands not visible with light microscope 

Term

 

 

CONDENSED CHROMOSOME

Definition

Short and visible

"X"

Term

 

 

CENTROMERE

Definition

Attachment place of spindle fibers on chromosome 

Term

 

 

HOMOLOGOUS CHROMOSOMES

Definition

Same size, shape, and same genes for traits but different detail

MIOSIS ONLY

Term

 

 

AUTOSOMES

Definition

Chromosomes that do not influence gender

Term

 

 

SEX CHROMOSOMES

Definition

X and Y chromosome that determine gender 

Term

 

 

PROPHASE

Definition

Chromatin condenses into chromosomes

Spindle fibres attach to centriomere

Term

 

 

METAPHASE

Definition

Chromsomes line up on equtorial plate

Term

 

 

EQUTORIAL PLATE

Definition

Center of nucleus

Term

 

 

ANAPHASE

Definition

Spindle fibres contract spliting chromatids

Term

 

 

TELOPHASE

Definition

Nucleous reappears 

Chromosomes unravel to form chromatins

Term

 

 

CYTOKINESIS

Definition

Cell division (cyotoplasm)

Term

 

 

BINARY FISSION

Definition

Equal division of nucleus and cytoplasm to form two identical organisms 

Term

 

 

BUDDING

Definition

Parent divides nucleus equally but not cytoplasm

Term

 

MEIOSIS

PROPHASE I

Definition

Homologous chromosomes undergo synapsis and cross over occurs 

Term

 

MIOSIS

METAPHASE I

Definition

Homologous pairs line up on equatorial plate 

Term

 

MEIOSIS

ANAPHASE I

Definition

Homologous chromosomes seperate and are pulled apart 

Term

 

MEIOSIS

TELOPHASE I

 

Definition

Daughter cells seperate

Each has one chromosome from each pair

Cytokenesis occurs

Term

 

 

MEIOSIS II

Definition

Exactly like mitosis minus interphase
