Cellular Reprod.
Cellular Reproduction Reveiw
| Question | Answer |
|---|---|
| The phase in the cell cycle during which the nucleus divides. | mitosis |
| The most common form of cell reproduction in multicellular organisms. | mitosis |
| Generally occurs when the organism is growing, repairing damaged tissue, or replacing dead cells. | mitosis |
| A form of asexual reproduction by which some single-celled organisms reproduce. | binary fission |
| A type of reproduction in which male and female reproductive cells combine to form offspring with genetice material from both cells. | sexual reproduction |
| The type of reproduction by which a single organism produces offspring that have the same genetic material. | asexual reproduction |
| A sperm or egg cell, containing half the usual number of chromosomes of an organism. | gamete |
| A part of sexual reproduction in which cells divide to form sperm cells in a male and egg cells in a female. | meiosis |
| The physical struction in a cell that contains the cell's genetic material. | chromosomes |
| Term used when a cell has only one set of chromosomes. | haploid |
| Term used when a cell contains two sets of chromosomes. | diploid |
| In some organisms, the process by which certain cells produce new tissue growth at the sire of a wound or lost limb. Also a form of asexual reproduction. | regeneration |
| A process of asexual reproduction in which an organism develops as an outgrowth, of the parent; breaking free and becoming separate and independent. | budding |
| A form of asexual reproduction where an organism is split into fragments. Each of these fragments develop into a mature, fully grown organism. | fragmentation |
| In the organizational hierarchy of organisms what is the simplest level? | cells |
| In the organizational hierarchy of organisms what is the most complex level? | organisms |
| Most cells reproduce through _________. | asexual reproduction |
| What type of reproduction has these characteristics: genetic material comes from only one parent organism and daughter organisms resulting from reproduction are genetically identical to the parent organism? | asexual reproduction |
| _________________________ occurs for the purposes of growth, damaged tissue repair, and replacement of cells. The new cells will have the same number of chromosomes as the original cell. | mitosis |
| Bacteria and some other unicellular organisms reproduce through the process of: | binary fission |
| A small growth develops on a hydra that eventually releases and develops into a new hydra. What must be true about the daughter hydra? | It is genetically identical to the parent plant and it was produced through a process called “budding.” |
| What will be true about a plant that develops from the cutting? | It may grow to look slightly different from the parent plant but it will be genetically identical. |
| When the root cell of a plant divides through mitosis into two new daughter cells, how do the daughters compare to the parent cell? | they are clones so they have the same genetic material as the parent |
| The anchor of a boat accidentally drags over a sponge and breaks the sponge into several pieces. If sponges are capable of asexual reproduction by fragmentation, what can we expect to happen with the sponge pieces? | they will grow into new sponges that are genetically identical to the damaged sponge |
| How does the number of chromosomes in the skin cell of a chimpanzee compare to the number of chromosomes in a chimpanzee sperm cell? | the skin cell will have twice as many chromosomes as the sperm cell |
| When the cells in the leaf of an oregano plant reproduce, the new cells have ________________________ chromosomes as the parent leaf cell. | the same number of |
| How do sex cells like sperm, eggs, and pollen differ from the other cells in a multi-cellular organism? | sex cells have only one set of chromosomes (one of each) for that species |
| If one egg cell of a female squirrel has 10 chromosomes, how many chromosomes will one of the squirrel’s skin cells have? | 20 |
| Mr. Moore wants to breed his male bearded dragon with Mr. Hodgdon’s female bearded dragon. If the breeding is successful, what will be true about the offspring? | They will have some characteristics of both parents but will not be identical to either |
| The process certain cells undergo in order to create sex cells or gametes. | meiosis |
| Meiosis occurs only in _________________ in plants and animals. | specialized sex organs |
| Meiosis results in the production of __________ sex cells | four |
| Sexual reproduction requires two parents that each provide_________of the genetic information the new offspring. | half |
| Most cells reproduce through ________________________ reproduction. | asexual |
| The daughter cells resulting from cell division are ____________________________ to the parent cell. | genetically identical |
| Bacteria and a few other unicellular organisms reproduce through a type of cell division known as __________________. | binary fission |
| List three reasons cells in multi-cellular organisms undergo cell division: a. _________________________ b. ____________________________ c. _________________________ | to grow, repair damaged tissue, replace dead cells |
| Most cells in multi-cellular organisms reproduce through a type of cell division known as ___________________ | mitosis |
| _____________________________is cell division that is responsible for the creation of sex cells. | meiosis |
| What are two examples of sex cells? a. ________________________ b. ___________________________ | egg and sperm |
| How does the number of chromosomes in a human skin cell compare to the number of chromosomes in a human muscle cell? | they are both diploid-same number of chromosomes |
| How does the number of chromosomes in a male rabbit’s liver cell compare to the number of chromosomes in one of its sperm cells? | liver cells will have twice the number of chromosomes |
| How does the number of chromosomes in the egg cell of a female alligator compare to the number of chromosomes in one of its lung cells? | egg cell will have half the number of chromosomes |
| When a plant cell divides and becomes two new cells, how does the number of chromosomes in the two daughter cells compare to the number of chromosomes in the parent cell? | They are identical, same number of chromosomes |
