Section 4-1 Cell Division and Mitosis

what is one reason cell division is important

growth- increases the number of cells

what is the second reason cell division is important

replace worn out cells

what is the third reason cell division is important

repair cells

what is the cell cycle mean

series of events that take place from one cell division to the next

does the cell cycle take the same amount of time for all cells?

no

the cell cycle is constantly repeated

true

what is the longest part of the cell cycle

interphase

interphase includes…

growth and development

the process in which the nucleus divides to form two identical nuclei

mitosis

what is the series of steps for mitosis

prophase, metaphase, anaphase, telophase

what is asexual reproduction

a new organism is produced from one parent organism

what does asexual reproduction have that is identical to the parent organism

hereditary material

an organism whose cells do not contain a nucleus, copies its genetic material, and then divides to form two identical organisms

fission

what are examples of fission

bacteria

a small, exact copy of the adult grows from the body of the parent

budding

what are examples of budding

hydra, yeast

what is regeneration or fragmentation

whole new organism grows from each piece of the parent

what are examples of regeneration or fragmentation

sponges, starfish, some worms

interphase

prophase

metaphase

anaphase

telophase

cytokinesis
