Mitosis

100

This is the initial stage of mitosis where the cell's chromatin condenses into visible chromosomes, the nuclear envelope begins to break down, and the mitotic spindle starts to form. 

• 
  

  
  

  
  

Prophase 

200

• 
  

  Phase of mitosis when the chromosomes line up at the cell's equator (MIDDLE
• ) with the spindle fibers attaching to them from opposite poles. 

  
  

  
  

• 
  

  
  

  
  

metaphase

300

Phase of mitosis when the chromosomes arrive at the poles, the nuclear envelope reforms around them, and the cell begins to divide into two daughter cells. 

telophase

400

• 
  

  Phase of mitosis when the sister chromatids separate and are pulled AWAY to opposite poles of the cell by the shortening spindle fibers. 

  
  

  
  

• 
  

  
  

  
  

anaphase

500

consists of the G1, S, and G2 phases where the cell grows, replicates its DNA, and prepares for division, before entering into the mitotic phases

interphase

Meiosis

100

Meiosis results in ____ daughter cells (how many?)

4

200

Meiosis that produces sperm cells is called ____

spermatogenesis

300

Meiosis that produces an egg and 3 polar bodies is called _____

oogenesis

400

name the 2 types of gametes that can be produced during meiosis 

sperm and egg

500

"diploid" refers to cells containing____ complete set(s) of chromosomes , while "haploid" refers to cells with _____ complete set(s).  (how many)

2/1

asexual and sexual reproduction

100

• The parent organism breaks into two or more pieces. Each piece then regenerates and develops into a complete, independent individual that are
  identical to the parent organism, making it a form of asexual reproduction

fragmentation

200

a new organism develops from an outgrowth of the parent organism, resulting in genetically identical offspring

budding

300

a form of asexual reproduction where offspring develop from an unfertilized egg

parthenogenesis 

400

species where individuals possess both male and female reproductive organs either at the same time or change back and forth

monoecious

500

species where individuals are either male or female (unisexual)

dioecious

types of birth +

100

egg laying

oviparous

200

live bearing 

viviparous

300

parent holds young in eggs within its body until they hatch

ovoviviparous 

400

a branch of mammals in which the young share nutrients with the mother within the womb (have a belly button)

placental

500

The formation of organs from the germ layers

organogenesis 

embryonic dev.

100

when a sperm and egg fuse this is called...

fertilization

200

when the nuclei of the sperm and egg join to produce a diploid cell this cell is called a ...

zygote

300

one the cell has cleaved to produce a solid ball of 16-32 cells it is called a ...(means raspberry in latin)

morula

400

this is formed when the cells continue cleaving to form a hollow ball with an inside layer and outer layer

blastula

500

in more complicated species there are 3 germ layers in the gastrula. the endoderm, ________ and _________

ectoderm/mesoderm
