What is the purpose of cell division in prokaryotes? What are four functions of cell division in eukaryotes? (2 words) What is the name for a non-reproductive cell in a eukaryote? For a reproductive cell in a eukaryote? (2 words) What are the two main stages in the cell cycle and their sub-phases (in order)? 10) (2 words) 15) 16) 17) 18) During the "S" phase of Interphase A duplicated chromosome is comprised of two __(20) that are connected with a 1211 . During mitosis, a complicated array of microtubules called the _122) connects the chromosomes to the poles of the cell. In an animal cell, structures called _(23) can be found at the poles. These structures plus the microtubules produce something called an_ _(24) which is named so because it looks like a "star". At the centromere of each duplicated chromosome can be found a _(25), which is a complicated structure that assists with movement of the chromosomes along the microtubules of the mitotic spindle (aka. spindle apparatus).

Answer 1

Purpose of cell division in prokaryotes :

Prokaryotes like bacteria propagate by binary fission. For unicellular organisms cell division is the only method to produce new individual .

In eukaryotes : cel division in eukaryotes is necessary for development , growth and repair of the organisms. Eukaryotic cell division ensure that each resulting daughter cell receives a complete copy of the organisms's entire genome.

Non reproductive cell in eukaryotes are known as somatic cells. Reproductive cell are germ cells.

The two main stages are the interphase ( sub phase are G1 phase, S phase and G2 phase) and mitotic phase( prophase, metaphase, anaphase, telophase).

S Phase is responsible for the replication of DNA
