Question 1

The production of new cells to bring about growth, replacement of damaged cells and the production of new generations of individuals among some groups of organisms can happen through one of the wonderful processes taking place in the body of living things—-

Answer 1

Cell division

Question 2

2 kinds of cell division

Answer 2

Mitosis and Meiosis

Question 3

Body cells in which mitosis happens

Answer 3

Somatic cells

Question 4

Responsible in the increase in weight and height of the baby girl as she grew and developed into a teenager.
It is also responsible for the healing of the wound when a part of the body is accidentally cut or scratched.

Answer 4

Mitosis

Question 5

Takes place in the ovaries and testes of animals, including humans.
It is responsible for the formation gametes or sex cells-sperm cell and egg cell.

Answer 5

Meiosis

Question 6

New cells are formed through—-

Answer 6

Cell division

Question 7

New cells are formed through cell division. This is one important breakthrough that was discovered by:

Answer 7

Rudolf Virchow

Question 8

In what year did Rudolf Virchow made his discovery?

Answer 8

1858

Question 9

What was Rudolf Virchow’s occupation?

Answer 9

German Pathologist

Question 10

The process of cell division is repeated over and over in a process called:

Answer 10

Cell Cycle

Question 11

Described as the resting stage, resting because the cell is not dividing but is very active in performing metabolic activities.

Answer 11

Interphase

Question 12

In this stage of mitosis, the nuclear membrane and nucleolus begin to breakdown.

Answer 12

Prophase

Question 13

In Prophase, the chromatins change until they become double-stranded and are called

Answer 13

Chromatids

Question 14

The double-stranded chromosomes are connected at one point called—

Answer 14

Centromere

Question 15

In this stage of mitosis, the double-stranded chromosomes called chromatids align themselves at the equator of the cell.

Answer 15

Metaphase

Question 16

Structure in centromere that attaches each chromatid to the spindle

Answer 16

Kinetochore

Question 17

In this stage of mitosis, forces originating from the poles pull the chromatids to move. Consequently, the centromere splits, separating the chromatids into new, single-stranded chromosomes.

Answer 17

Anaphase

Question 18

the final stage of mitosis. The chromosomes now have reached the opposite poles.

Answer 18

Telophase

Question 19

What stage does mitosis and meiosis have in common and are similar?

Answer 19

Prophase

Question 20

The metaphase stage of mitosis and meiosis are the same except:

Answer 20

In meiosis, there is a pairing of homologous chromosomes, forming a tetrad

Question 21

Homologous chromosomes

Answer 21

Synapsis

Question 22

One set of chromosomes(ex: gametes)

Answer 22

Haploid

Question 23

In humans, haploids are

Answer 23

number=23

Question 24

Two sets of chromosomes(ex: all body cells except gametes)

Answer 24

Diploid

Question 25

In humans, diploids are

Answer 25

2n=46
