Daughter cells | the two new cells that are created during reproduction |
How do plants reproduce? | both sexually and asexually |
How have plants adapted to reproduce better and what is the benefit of each? | sexually insures new chromosomes while asexually is an exact copy. |

proximal | towards body |
cranial | head |
lateral | side |
ventral | underneath |
Radial | body parts organized around a central point |
Bilateral | mirror halves |
Asymmetry | no body plan |
Organization of Life | cells->tissue->organs->organ systems->organisms |
Cells | basic unit of life. |
Tissue | group of similar cells working together |
Organs | group of different tissues working together to perform a specific job |
organ system | Many organs working together to perform a specific job |
organism | A living thing that carries out its own life activities |

What provides plants support and protection but is missing in animal cells? | a cell wall |
What is a eukaryotic cell? | a cell with a nucleus such as plant and animal cells. |
What is a prokaryotic cell? | cells without nucleus such as bacteria. |
What does the cell theory say about where cells come from? | Cells come from other cells. |
What does the cell theory say is the basic unit of life? | the cell |
What is the smallest number of cells needed for an organism to be alive? | one |
Over many generations polar bears grow bigger feet to allow it to easily walk on ice, this is what type of living characteristic? | Living things can adapt. |

Prokaryotic cells | do not have a nucleus |
Eukaryotic cells | have a nucleus |
what does multi-cellular mean? | More than 1 cell |
What is osmosis? | the diffusion of water |
What is diffusion? | The movement of particles from high concentration to low concentration. |

Which organelle is semi-permeable? | the cell membrane. |
List the 6 stages of mitosis. | Interphase, prophase, metaphase, anaphase, telophase, cytokinesis |
The "resting" phase of mitosis | Interphase |
Nucleus breaks apart; chromosomes look like a bowl of spaghetti | Prophase |
Chromosomes line up in the middle of the cell. | Metaphase |
Chromosomes move to each side of the cell. Copied ones on a side and original on the other side. | Anaphase |
Nucleus begins to reform around each set of chromosomes. | Telophase |
Cell pinches off creating two new daughter cells. | Cytokinesis |
sexual reproduction | two parent reproduction resulting in different offspring. |
asexual reproduction | single parent reproduction resulting in identical offspring. |
sexual reproduction advantage | offspring are different |
sexual reproduction disadvantage | slow process taking months to create offspring |
asexual reproduction advantage | fast process taking minutes to hours to create offspring |
asexual reproduction disadvantage | offspring are identical |
