Question

why?
cells reproduce through mitosis to make exact copies of the original cell. this is done for growth and repair. sexually - reproducing organisms have a second form of cell division that produces reproductive cells with half the number of chromosomes. this process is called meiosis, and without it, humans, oak trees, beetles, and all other sexually - reproducing organisms would be vastly different than they are today.
model 1 – meiosis i
images of different stages of meiosis i: cell from the sex organs (ovaries/testes in animals) during interphase i, early prophase i, late prophase i, metaphase i, anaphase i, telophase i

1. according to model 1, in what type of organs are the cells that enter meiosis i found?
2. considering what you already know about mitosis in cells, what event must take place during interphase before a cell proceeds to division?

Explanation:

Question 1

The first diagram in Model 1 is labeled "Cell from the sex organs (ovaries/testes in animals) during Interphase I". So the cells entering meiosis I are from sex organs.

In mitosis, before cell division (including the start of meiosis which has similar interphase requirements), the cell must replicate its DNA (and organelles) during interphase. This is to ensure each new cell gets a complete set of genetic material.

Answer:

Sex organs (e.g., ovaries or testes in animals)
