Reproduction

Question 1

Antigens

Answer 1

Any foreign body that enters the body and triggers an immune response.

Question 2

Cancer

Answer 2

Rapid uncontrolled cell division of mutated cells.

Question 3

Diploid Number

Answer 3

Number of chromosomes in the body cells.

Question 4

Meiosis

Answer 4

The process in which gametes(sex cells) are produced.

Question 5

Kaploid or Monoploid Number

Answer 5

Number of chromosomes in the sex cells.

Question 6

Chromosomes

Answer 6

Rod like structures in cells that divide and contain genetic information of No the organism. Kept in nucleus of the cell.

Question 7

Centrioles

Answer 7

Cylinder shaped organelles near the nucleus of an animal cell that are involved in mitosis.

Question 8

Centromere

Answer 8

The region of attachment of who sister chromatids.

Question 9

Chromatin

Answer 9

The material that makes up chromosomes.

Question 10

Aster

Answer 10

Star shaped structure formed mitosis in animal cells by fibers from the centrioles.

Question 11

Mitosis

Answer 11

Separation of chromosomes and their distribution from the parent cell to the daughter cells.

Question 12

Interphase(IPMAT)

Answer 12

• Resting phase
• Lasts from the end of one cell division to the beginning of the next.
• Duplication of chromosomes and doubles chromosomes.

Question 13

Prophase(IPMAT)

Answer 13

• Chromosomes condense and become visible.
• Doubled chromosomes called chromatids and are connected to centromeres.
• Microtubules span across cell for spindle to fasten.
• Nuclear membrane breaks down.

Question 14

Metaphase(IPMAT)

Answer 14

• Centromeres are at opposite ends.

- Centromeres start dividing and chromosomes giveNo rise to single stranded, identical chromosomes.

Question 15

Anaphase(IPMAT)

Answer 15

• Duplicated chromosomes move to opposite poles.

- Results in identical sets of chromosomes at either ends of cell.

Question 16

Telophase(IPMAT)

Answer 16

• Chromosomes uncoil and become thread like.
• Spindles disappear
• Nuclear membrane reforms
• Cell membrane begins to pinch in.

Question 17

Cytokinesis

Answer 17

• Starts in anaphase and finishes in telophase.
• The division of cytoplasm.
• Results in 2 daughter cells the same size.

Question 18

Asexual Reproduction

Answer 18

• 1 parent

- No variationI (offspring identical to parent cell).

Question 19

Sexual Reproduction

Answer 19

• 2 parents

- Variation(offspring not identical to parent cell).
