Learning objectives Unit 2 Reproduction

1.

define traits

2.

define heredity

3.

the role of the nucleus and its contents in determining traits and controlling cell
division

4.

define gene

5.

define DNA

6.

define chromosome

7.

describe genes as being composed of DNA

8.

describe
chromosomes as being composed of numerous genes

9.

define gene mutation

10.

define mutagen

11.

give examples of mutations caused by:

(i)

nature

(ii)

human activity

12.

illustrate and describe the basic processes of cell division, including what happens
to the cell membrane and th
e contents of the nucleus

-

define cell cycle

-

list the stages of the cell cycle

-

define mitosis

-

define cytokinesis


13.

state and briefly describe the four phases of mitosis followed by cytokinesis.
Include:

i)

Prophase

ii)

Metaphase

iii)

Anaphase

iv)

Telophase


14.

distinguish
between sexual and asexual reproduction in representative organisms




15.

define asexual reproduction

-

explain methods of asexual reproduction using an example. Include:

(i)

binary fission

(ii)

budding

(iii)

fragmentation

(iv)

vegetative reproduction

(v)

spore formation


16.

define sexua
l reproduction


17.

define gamete, fertilization, zygote, embryo

-

describe the role of meiosis in sexual reproduction

-

state and briefly describe the eight phases of meiosis

-

define diploid

-

define haploid

-

describe interkinesis

Meiosis I

-

Prophase I: homologues
chromosomes pair up

-

Metaphase I: homologus chromosomes pair up at the equator

-

Anaphase I: homologuous chromosomes separate and are pulled to
opposite poles

-

Telophase I: homologuous pairs have moved to opposite ends of
the cell and cell begins to divide

Mei
osis II

-

Prophase II: nucleus contains only 1 chromosome from the
homologous pair in each cell

-

Metaphase II: chromosomes line up at the equator

-

Anaphase II: half of the chromosomes are pulled to opposite poles

-

Telophase II: a nuclear membrane forms around e
ach set of
chromosomes and the cell begins to divide to produce four haploid
gametes

18.

compare and contrast mitosis and meiosis. Include:

(i)

types of cells

(ii)

number of daughter cells produced

(iii)

amount of genetic material in each daughter cell

19.

Interkenisis: the cell

grows and makes various proteins


20.

distinguish between sexual and asexual reproduction in representative organisms

21.

explain how various organisms reproduce sexually. Include:

(i)

moss

(ii)

flowering plant

(iii)

insect
