Definition
| In order to stay small. Small size makes it easier for substances to move from the outside of cells to the middle of the cell quickly - due to the shorter distance to travel |
|
|
Term
| How do we represent the benefit of cells staying small? |
|
Definition
| The must maintain a high surface area to volume ratio |
|
|
Term
| What are features of asexual reproduction? |
|
Definition
| Only one parent, uses mitosis, makes identical offspring or clones |
|
|
Term
| What are the uses of asexual reproduction? |
|
Definition
| Growth, repair, reproduction |
|
|
Term
| What are advantages of asexual reproduction? |
|
Definition
| It occurs rapidly since you often start with a large cluster of cells, make many identical offspring fast |
|
|
Term
| What are disadvantages of asexual reproduction?Wha |
|
Definition
| Since the offspring are all identical, they all will have the same flaws, so they all are suceptible to the same diseases, etc. |
|
|
Term
| What are the features of sexual reproduction? |
|
Definition
| Two parents, uses meiosis, produces variation in offspring, who are different from their parents |
|
|
Term
| What are the uses of sexual reproduction |
|
Definition
| The formation of offspring only! |
|
|
Term
| What are the advantages of sexual reproduction? |
|
Definition
| The production of variation in offspring so they are better able to cope with changing conditions; you can produce large numbers of offspring |
|
|
Term
| What are the disadvantages of sexual reproduction? |
|
Definition
| You cannot predict what combination of traits the offspring will be, it takes a long time for offspring to reach maturity since you start with a single cell, a zygote. |
|
|
Term
|
Definition
| A sequential series of processes that takes the cell from one round of division to the next |
|
|
Term
|
Definition
| The first stage of the cell cycle; the cell grows and does normal processes |
|
|
Term
|
Definition
| Synthesis; the chromosomes are copied |
|
|
Term
|
Definition
| The cell prepares for cell division; it makes sure all processes and components are working correctly |
|
|
Term
|
Definition
| Mitosis; the division of the nucleus |
|
|
Term
|
Definition
| The division of the cytoplasm |
|
|
Term
|
Definition
| Structures found in the nucleus that are made up of DNA and associated proteins and contain the genetic instructions for an organism |
|
|
Term
|
Definition
| DNA and associated proteins called histones; chromatin makes up chromosomes |
|
|
Term
|
Definition
Copies of chromosomes that are made during synthesis

Term
|
Definition
| The region of a chromosomes where two sister chromatids are held together |
|
|
Term
|
Definition
| A structure found in animal cells that helps organize the protein cables that move chromosomes during cell division |
|
|
Term
|
Definition
| Cell division in prokaryotic cells like bacteria; produces two identical cells |
|
|
Term
| Mnemonic device or saying to help you remember the phases of the cell cycle |
|
Definition
| I picked more apples than carrots: Interphase, prophase, metaphase, anaphase, telophase, cytokinesis |
