What is the period of time between the first and second meiotic divisions?
It is called Interkinesis
Name and briefly describe the stages of the two meiotic divisions of meiosis?
the stages of the two meiotic divisions of meiosis?
What types of cell divisions are involved in creating a puppy?
Meiotic cell divisions form the sperm and egg cells that unite to form the first cell of a puppy. Then mitotic cell divisions continue to create the puppy from that single cell.
The period of growth in between cell divisions is called?
It is interphase, which is divided into three stages. First is a growth stage (G1), during which the synthesis of proteins and other necessary molecules takes place and the cell becomes larger. At about mid-interphase the cell replicates its nuclear DNA (S phase; the letter stands for "synthesis"). Finally there is a second growth stage (G2).
How does pro-phase look different from inter-phase?
an interphase is the stage of a cell between two successive mitotic or meiotic divisions an a prophase is the first stage of mitosis or meiosis in eukaryotic cell division, during which the nuclear envelope breaks down and strands of chromatin form into chromosomes.

What is sporogenous tissue?
sporogenous tissue is a combination of sporogenous cells which capable of undergoing the meiotic divisions.

do you mean milotic? and there is no suck thing as a meiotic.
Meiotic cell division occurs in a special organ known as?
meiotic cell division occurs in the gonads
What are the types of cells in meiosis?
Meiotic divisions The two meiotic divisions may be divided into a number of distinct stages. Meiotic prophase refers to the period after the last cycle of DNA replication, during which time homologous chromosomes pair and recombine. The end of prophase is signaled by the breakdown of the nuclear envelope, and the association of the paired chromosomes with the meiotic spindle. The spindle is made up of microtubules that, with associated motor proteins, mediate chromosome movement. In some cases (such as human sperm formation), the spindle is already formed at the point of nuclear envelope breakdown, and the chromosomes then attach to it. In other systems (such as human female meiosis), the chromosomes themselves organize the spindle. Metaphase I is the period before the first division during which pairs of interlocked homologous chromosomes, called bivalents, line up on the middle of the meiotic spindle. The chromosomes are primarily (but not exclusively) attached to the spindle by their centromeres such that the centromere of one homolog is attached to spindle fibers emanating from one pole, and the centromere of its partner is attached to spindle fibers from the other pole (see illustration). The bivalents are physically held together by structures referred to as chiasmata that are the result of meiotic recombination events. In most meiotic systems, meiosis will not continue until all of the homolog pairs are properly oriented at the middle of the spindle, the metaphase plate. The orientation of each pair of homologs on the spindle occurs in a random fashion, such that the paternally derived homolog of one bivalent may point toward one pole of the spindle, while in the adjacent bivalent the maternally derived homolog is oriented toward the same pole.
