10-2 cell division

Telophase

A nuclear envelope reforms around each cluster of chromosomes. The nucleus becomes visible in each daughter nucleus

G1 phase

Cells do most of their growing increasing in size and synthesizing new proteins and organelles

S

Chromosomes are replicated and the synthesis of DNA molecules take place. also, keep proteins associated with the chromosomes are synthesized

When chromosomes become visible at the beginning of cell division, what does each chromosome consist of?

Each chromosome consists of two identical sister chromatids

Centromere

Each pair of chromatids is attached to an area called

Cell plate

It forms midway between the divided nucleus during cytokinesis in plant cells

G2

Many of the organelles and molecules required for cell division are produced

How does cytokinesis occur in most animal cells?

The cell membrane is drawn in word until the cytoplasm is pinched into two nearly equal parts

Prophase

The chromosomes become visible. The centrioles take up positions on opposite sides of the nucleus.

Metaphase

The chromosomes line up across the center of the cell

Anaphase

The chromosomes move until they form two groups near the poles of the spindle

Cytokinesis

The division of the cytoplasm itself

Prophase, metaphase, anaphase phase, telophase

The four phases of mitosis

Interphase

The period of growth in between cell divisions

Cell cycle

The series of events that cells go through as they grow and divide

Spindle

The spindle is a fanlike microtuble structure that help separate the chromosomes

G1, S, G2

The three phases interface is divided into

Centrioles

To Teenies structure is located in the cytoplasm near the nuclear envelope at the beginning of prophase

Mitosis and cytokinesis

Two main stages of cell division
