| What are the three types of life cycles |
|
Definition
Zygotic- is accomplished by spores with sporangia A zygotic meiosis is a meiosis of a zygote immediately after karyogamy, which is the fusion of two cell nuclei. This way, the organism ends its diploid phase and produces several haploid cells. These cells divide mitotically to form either larger, multicellular individuals, or more haploid cells. Two opposite types of gametes (e.g., male and female) from these individuals or cells fuse to become a zygote.
Gametic- Egg Sperm

Term
| what is the difference between obligate and facultative anaerobes |
|
Definition
| Our muscles usually have oxygen available to them....but they can make do without oxygen...hence their faculties still operate without oxygen (but really they would rather have oxygen). Obligate anerobes _must_ be in an anaerobic environment...they die if oxygen is there. It's not just that they can function without oxygen, it's that they must be in a place with no oxygen. |
