|
||||
|---|---|---|---|---|---|
| Prophase | - long strands of DNA condense to distinct chromosomes, each with two chromatids that are exact copes of each other
- the nuclear membrane disappears
🗑
|
||||
| Telophase | new nuclear membranes form
🗑
|
||||
| Metaphase | chromosomes line up in the middle of the cell
🗑
|
||||
| Anaphase | - chromatids of each chromosome split into two separate chromosomes
- separated chromosomes pull to the opposite ends of the cell
🗑
|
||||
| Cytokinesis | - cell pinches and divides
- is the division of the parent cell's cytoplasm
🗑
|
||||
| animal cell | the cell membrane pinches; membrane forms around each cell
🗑
|
||||
| plant cell | a cell plate forms where the cell wall will divide the two cells
🗑
|
||||
| DNA | a chemical that contains information for an organism's growth and functions
🗑
|
||||
| Chromosomes | compacted DNA
🗑
|
||||
| Cetromere | holds together chromatids
🗑
|
||||
| Chromatids | a duplicated chromosome consists of two
🗑
|
||||
| cell cycle | the normal sequence of development and division of a cell
🗑
|
||||
| Interphase | the part of the cell cycle during which a cell is not dividing
🗑
|
||||
| Mitosis | the part of the cell cycle during which the nucleus divides
🗑
|
||||
| Asexual Reproduction | - one organism produces one or more new organisms that are identical to itself and that live independently of it
- one parent organism, rate of reproduction is rapid, offspring identical to parent
🗑
|
||||
| Binary Fission | occurs when the parent organism splits in two, producing two completely independent daughter cells
🗑
|
||||
| budding | a process in which an organism develops tiny buds on its body
🗑
|
||||
| regeneration | the process of new tissue growth at sites of a lost limb
🗑
|
||||
| Sexual Reproduction | two parent organisms, rate of reproduction is slower than rate for asexual reproduction, offspring have genetic information from two parents
🗑
|
||||
| a plant cutting is | genetically identical
🗑
|
||||
| a new plant from seed is | genetically similar
🗑
|
||||
| a cell produces two genetically identical daughter cells when it | undergoes mitosis
🗑
|
||||
| most multi cellular organisms grow and develop because their cells | continue to divide
🗑
|
||||
| Which of the following correctly sequences the steps in the cell cycle? | interphase, mitosis, and cytokinesis
🗑
|
||||
| cells prepare for cell division during | interphase by duplicating their DNA
🗑
|
||||
| After mitosis, the number of chromosomes in a daughter cell is | the same as the number in the parent cell
🗑
|
||||
| Asexual reproduction in most organisms involves | mitosis by one parent
🗑
|
||||
| A leaf breaks off a plant. Someone puts the stem of the leaf into water. Roots eventually grow from the stem. This is an example of | rengeneration
🗑
|
||||
| characteristic of asexual reproduction | it can result in large numbers of offspring
🗑
|
||||
| as you become an adult, the cells in your body | keep dividing
🗑
|
||||
| How do cells share genetic material? | they divide
🗑
|
||||
| - the cell cycle beings with - A cell grows and carries out life functions in | interphase
🗑
|
||||
| How does a cell prepare for mitosis? | it makes exact copies of its DNA
🗑
|
||||
| A cell grows and carries out life functions in | a cell plate grows between the two new nuclei
🗑
|
||||
| The offspring produced by asexual reproduction | are genetically identical to their parents
🗑
|
||||
| The cell cycle ends with | cytokinesis
🗑
|
||||
| What are the smallest units able to perform the basic activities of life? | cell
🗑
|
||||
| New cells form as the result of | a division of existing cells
🗑
|
||||
| All of the cells in your hand have | one complete copy of DNA
🗑
|
||||
| all cells come from | cells
🗑
|
||||
| DNA must be duplicated before mitosis so that | each daughter cell gets a complete copy of DNA
🗑
|
||||
| the steps of mitosis | prophase, metaphase, anaphase, telophase
🗑
|
||||
| During interphase, | the DNA in chromatin is duplicated
🗑
|
||||
| When a cell prepares to divide, its genetic information condenses from a mass of loose strands into tightly wound structures called | Chromosomes
🗑
|
||||
| An organism that produces other organisms is called | a parent
🗑
|
||||
| organisms produced through mitosis | are exact copies of the parent
🗑
