Zoology |
The scientific study of animals |
|

|
|
Cell theory |
All organisms have cellular organization excluding viruses. All existing cells come from previously existing cells |
|
|
|
kary-- |
nucleus |
|
|
|
karyokinesis |
division of nucleus |
|
|
|
cytokinesis |
division of cytoplasm |
|
|
|
What are the two types of cellular division? |
meiosis and mitosis |
|
|
|
What is Mitosis? |
nuclear division involving separation of replaced chromosomes so that each daugghter nucleu has the same number an kind of chromosomes as the other and original parent nucleus |
karyokinesis |
|
|
What does Mitosis produce?? |
twin daughter nuclei |

|
|
Science |
any field of study that ROUTINELY uses the Scientific Method as a way of making discoveries about natural phenomena |

|
|
asexual reproduction |
One parent. The offspring of one parent are usually genettically the same as parent (clones) |
|
|
|
Give two examples of asexual reproduction |
Budding Binary fission |
|
|
|
Binary fission |
Parent divides into two equal sized individuals |
|
|
|
Budding |
New individual arises as an outgrowth (bud) of parent that eventually detaches from repeated mitosis and cytokinesis. |
|
|
|
Fragmentation |
Mostly about plants. E.g. strawberry plants reproduce plantlets along the leaves |
|
|
|
Parth- |
Maiden |
Parthenon. |
|
|
Parthenogenisis |
The development of an embryo/individual from an UNFERTILIZED egg. |

Yes. Aphids, some zooplankton species and a few vertebrates can. |

Euglena can only occur ___________. |
Asexually |
|
|
|
Biparental production |
Two parents combine half their nuclear genetic material (by the supermarket cell chromosome and egg chromosome) to produce a zygote. |
|
|
|
Zygote |
Fertilized egg |
