Mitosis

Question 1

Centriole Pair

Answer 1

All animal cells have two small organelles known as centrioles. They help to divide. Centrioles are located in the nucleus, made from 9 bundles of microtubules in a ring.

Question 2

Spindle Fibres

Answer 2

Spindle fibres form a protein structure that divides the genetic material in a cell.
Necessary to equally divide the chromosomes in a parent cell —> 2 daughter cells.

Question 3

Sister Chromatids

Answer 3

Sister chromatids is when a single chromosome has been copied, each spindle is called a sister chromatid.
That is 2 sister chromatids held together by a centromere - special part of a chromosome.

Question 4

Cleavage Furrow

Answer 4

Microfilaments during cytokinesis that splits the two daughter cells membrane in half.

Question 5

Mitosis

Answer 5

= 2 daughter cells
Same chromosome number in a parent and daughter cells.
Genes in nuclei of daughter cells are identical to genes in a nucleus of parent cells.
Replicates in diploid cells
Asexual reproduction
No crossing over occurs
Results in body cells
Cell division

Question 6

Interphase

Answer 6

DNA replicates
Cells grow + carry out normal cell activity and replicates other organelles
Cells spend most of its life here

Question 7

Cytokinesis

Answer 7

Division of the rest of the cell (cytoplasm + organelles) after the nucleus divides

Question 8

Cell Cycle Order

Answer 8

Interphase
Prophase
Metaphase
Anaphase
Telophase
Cytokinesis

Question 9

Cell Division

Answer 9

Process when a cell divides into 2 new cells.
If the cell gets too big, it cannot get enough nutrients into the cell.
Many organisms, especially unicellular reproduce by cell division called asexual reproduction.

Question 10

Gamete

Answer 10

Only one egg results from meiosis. The other three cells are called polar bodies.
