Asexual Reproduction

Question 0

How many pairs of chromosomes do humans have in each cell?

Answer 0

23 pairs

Question 1

How many chromosomes do humans have in each cell?

Answer 1

46

Question 2

What is the name for chromosomes that have gene codes for a trait but have different variations of that trait?

Answer 2

homologous chromosomes

Question 3

What are the phases a cell goes through during its life?

Answer 3

interphase, prophase, metaphase, anaphase, telophase

Question 4

the cell cycle

Answer 4

sequence of growth and division in a cell

Question 5

interphase

Answer 5

the first phase of cell division. DNA replicates itself and forms a sister chromatid for each chromosome.

Question 6

mitosis

Answer 6

a period of nuclear cell division, two daughter cells are formed ( each contains a full set of chromosomes ) , identical to parent cells (clone)

Question 7

prophase

Answer 7

chromosomes become visible, nuclear envelope disintegrates, centrioles migrate to opposite poles, spindle fibers form between centrioles

Question 8

metaphase

Answer 8

chromosomes become attached to spindle fibers by the centromeres, chromosomes line up in the middle

Question 9

centromeres

Answer 9

the protein connecting the sister chromatids together

Question 10

anaphase

Answer 10

sister chromatids separate, spindle fibers shorten and pull one of the double chromosomes to a pole

Question 11

telophase

Answer 11

chromatids reach opposite ends of the poles, two nuclear membranes form, chromosomes unwind and loose their shape

Question 12

When does a cell carry out metabolism?

Answer 12

interphase

Question 13

cytokinesis

Answer 13

the cell pinches together and 2 cells are formed

Question 14

What organelle do animals have that plants do not?

Answer 14

centrioles

Question 15

In a plant cell, the cell can not go through cytokinesis because of the cell wall. What forms across the middle of a cell?

Answer 15

cell plate

Question 16

When do our cells divide?

Answer 16

growth, repair, development and maintenance

Question 17

asexual reproduction

Answer 17

also uses mitosis, new cells are identical, offspring are clones of parents, no variation unless a mutation occurs

Question 18

binary fission

Answer 18

nuclear material and cytoplasm of a cell divide equally

ex bacteria and ameba

Question 19

budding (unicellular)

Answer 19

cytoplasm divides unequally to create a smaller bud

ex yeast

Question 20

budding (multicellular)

Answer 20

outgrowth from the body of a parent that develops into a completely different organism, may detach or remain attached

Question 21

Equatorial plate

Answer 21

The middle of a animal cell

Question 22

Sporulation

Answer 22

Specialized cells are released by parents enclosed in protective capsules develop into new individual when environment is good (dandelion)

Question 23

Regeneration

Answer 23

Development of lost parts or growth of an entire organism from part of original organism (worm starfish)
