Cell Cycle

Most cells in an organism go through a cycle of growth, development, and division called the ---- -----

Interphase

Is the period during the cell cycle of a cell's growth and development

Mitosis

The nucleus and its contents divide

Sister Chromatids

Two identical chromosomes, called ------ ----------, make up a duplicated chromosome

Centromere

Sister chromatids are held together by a structure called the ----------.

Cytokinesis

During ----------- the cytoplasm and its contents divide.

Daughter Cells

Are the two new cells that result from mitosis and cytokinesis.

Prophase

The nucleolus disappears, and the nuclear membrane breaks down. Spindle fibers begin to form. Copied DNA condenses into chromosomes.

Metaphase

Chromosomes line up in single file at the middle of the cell.

Anaphase

Sister chromatids separate. Spindle fibers begin to shorten, pulling chromatids toward opposite sides of the cell. The cell begins to lengthen.

Telophase

A nuclear membrane forms around the chromatin. Chromosomes begin to unwind. Spindle fibers begin to break down. Two identical nuclei form.

Does the cell that the daughter cells are made of still exist (Yes or No)

No

What are the results of cell division?

Reproduction, growth, replacement, and repair

A duplicated chromosome is made of two?

Sister Chromatids

Which is NOT part of mitosis? (put the term)
a: anaphase
b: interphase
c: prophase
d: telophase

interphase

Cell Differentiation

The process by which cells become different types of cells is called ---- ----------------

Stem Cell

Are unspecialized cells that are able to develop into many different cell types

Plant cells also have unspecialized cells similar to ANIMAL stem cells. These cells are grouped into areas of a plant called?

meristems

Organs

are groups of different tissues working together to preform a particular job

Organ Systems

are groups of different organs that work together to complete a series of tasks

Tissue

are groups of similar types of cells that work together to carry out specific tasks

Humans have four main types of tissue, what are they?

muscle, connective, nervous, and epithelial

Plants have three main types of tissue, what are they?

dermal, vascular, and ground tissue

The new cells formed by mitosis are called?
