| microbiology | science that studies all one-celled organisms |
| Three Kingdoms | Animal. Plant, Protista |
| Which kingdom do all three microorangisms belong to? | potista |
| scientific name for ameba | Ameba proteus |
| scientific name for Paramecium | Paramecium caudatum |
| scientific name for Euglena | Euglena gracilis |
| How does the Ameba ingest food? | Pseudepods |
| How do Amebas move from one location to another? | Flowing of protoplasm and pseudopod formation |
| What is the function of the Contractile Vacuole? | Removal of excess water |
| How do Paramecia ingest prey? | Trichocysts, cilia, oral groove, gullet, food vacoule |
| How do Cilia enable Paramecia to move? | nnnnnnnnnnnnnnnn |
| What are Trichocysts used for? | To paralyze prey and protection |
| Why do Paramecia have two nucle? | Micronucleus for reproduction, macronucleus for regulation |
| Whay are cParamecium considered more complex thant the ameba? | constant shape, oral goove & gullet, trichocysts, anal pore, sexual reproduction |
| Why are Euglena considered plantlike? | contains chlorophyll, choloroplasts, carries on photosynthesis |
| What is the function of the Euglena's Eyespot? | light sensitive structure used in detecting light |
| How do Euglena make their own food? | Photosynthesis |
| How does the process of Binary Fission in one-celled organisms produce offspring? | Equal splitting of parent into two off spring binary fission |
| How does the Euglena move? | Flagella, ship like movements f the flagellum pull the euglena through the water |
| How does the mmmmmmmm | jjjjjjjjjjjjjjjjjjjjjjjjjj |
| Miotic cell division is used for | asexual reproduction in one celled organisms and gowth in multicellualr organisms |
| how many stages does Mitotic division occur in? | Six stages |
| Interphase or resting stage | chromosomes makes a copy of itself, the centrosome with two entrioles appear outside the nucleus |
| Phophase | Nucleolus, nuclear membrane and centrosome disappear, cnetrioles move to opposite ent of the cell poles and spindle fibers form between them |
| Metaphase | Chromosomes attach themseleves midway between the poles |
| anaphase | the spindle fibers shorten and pull the double chromosomes apart |
| Telophase | The cell begins to divide in half |
| Cytoplasmic Division | The cell completely divides into tow new daughter cells |
| What are the results of Mitotic Cell Division? | There are two new cells each having the same number of chromosomes as the parent cell, each daughter cell in equal in size however, each is half the size of the parent cell |
| Meiotic Cell Division | Special cell division that occurs only in the testis of males and ovaries of females |
| What does Meiotic cell division result in? | Production of sperm cells in males and egg cells in females |
| How many chromosomes do sperm and egg cells contain? | 23 in humans |
| Meitotic division in males | 46 chromosomes to 23 in 4 sperm |
| Parent Sex cell in Testis | 23 chromosomes |
| Meiotic Division in Females | 23 chromosomes in 4 eggs 3 interactive polar bodies |
| What are the results of Meiotic Cell Division? | four new cells ( sperm and egg) are produced haveing half the number of chromosomes as the parent. 4 sperm cells are active, 1 of the 4 egg cells can be fertilized. |
