Flashcards in Chapter 3 Part 3 Deck (21):
1

Cell growth between divisions -DNA and organelles replicate

Interphase

2

Cell divides

Mitotic phase

3

Separates 46 double stranded chromatids among 2 cells

Mitosis

4

Nuclear envelopes disappears

Prophase

5

Double stranded chromatids line up at middle of cel

Metaphase

6

Each chromatid strand moves away to opposite poles of cel

Anaphase

7

Nuclear envelope reforms

Telophase

8

Divides cytoplasm into 2 identical cells

Cytokinesis

9

Produces genetically non identical sex cells (gametes) by meiosis - each sex cell contains 23 chromosomes

Reproduction cel division

10

Cancer causing agents that produce permanent DNA change known as mutations

Carcinogens

11

A group of cells that divide without control

Tumor (neoplasm)

12

Tumors have the ability to metastasize (spread) to other body parts

Cancerous (malignant)

13

Tumors do not metastasize

Benign (non malignant)

14

Provides pain relief reduces swelling by increasing lymph flow decrease depression and anxiety

Massage

15

Radiation,surgery,chemotherapy

Cancer treatments

16

Involves the progressive alternation of body's homeostatic responses

Aging

17

Causes include the formation of free radicals and ireversible cross links between cel membrane proteins

Aging

18

Vitamin C,E and selenium decrease free radical formations

Antioxidants

19

Normal genetically programmed cell death

Apoptosis

20

A pathological cell death resulting from disease

Necrosis

21

Produces genetically identical body cells by mitosis

Somatic cell division
