cell structure and function

100

^{what is cell theory?}

the theory that all organisms are made out of one or more cells.

200

^{what does a prokaryotic cell lack of ?}

membrane-bound nucleus 

300

^{how are eukaryotic cell DNA strands like ?}

linear 

400

^{What does cytoskeleton do ?}

helps transport materials within the cell 

500

^{what are cells surrounded by?}

cell membrane 

cell division

100

^{what kind or molecules do chromosomes include?}

DNA

200

^{what are 2 types of cell divisions?}

Binary and mitosis 

300

^{what happens in eukaryotic cell division?}

a growth period that separates the DNA and duplicates 

400

^{how many phases does a eukaryotic cell go through?}

4

500

^{cells that lose the ability to regulate the rate of cell division Are called?}

cancer cells

cell transport

100

^{what are the two types of cell transports?}

passive transport and active transport.

200

^{what happens during passive transport?}

substances and molecules move away from high concentration to low concentration areas 

300

^{what happens during active transport?}

the energy moves materials in different directions than normally 

400

^{what happens in endocytosis ?}

some materials are moved into cell via a vesicle that enters the cytoplasm 

500

^{what happens in exocytosis?}

some cells are moved out of the cells via a vesicle that fuses with the cell membrane and opens on the outside of the cell

asexual reproduction

100

^{what occurs when only one parent contributes genes to the offspring?}

asexual reproduction

200

^{resulting offspring of asexual reproduction are?}

identical to he parent

300

^{do organisms that undergo asexual reproduction the same as the ones in sexual reproduction?}

no

400

^{is bacteria produced asexually ?}

yes

500

^{how does asexual reproduction happen?}

it occurs when the mitosis during cell division is produces two or more genetically identical offspring

sexual reproduction

100

^{what is the creation of an offspring by combining the genetic material from two parent ?}

sexual reproduction 

200

^{what does sexual reproduction include?}

meiosis , spermatogenesis, oogenesis, and fertilization

300

^{what is the resulting of sexual offspring?}

it gets something unique from both parents 

400

what can trisomy cause?

down syndrome 

500

^{how does sexual reproduction happen?}

when the male sperm get to the females egg
