Reproduction - sexual and asexual

Question 2

What is Asexual Reproduction?

Answer 2

The formation of a new organism from only one parent.

Question 3

What is Budding?

Answer 3

(e.g. of yeast and hydras) occurs when a small part of the parent’s body separates from the rest and develops into a new individual

Question 4

What is Binary Fission?

Answer 4

(e.g. of bacteria and Amoeba) when a cell replicates to form 2 new ‘daughter’ cells.

Question 5

What is Fragmentation?

Answer 5

(e.g. of flatworms and starfish) occurs when a parent body is broken into pieces, and each piece may form a new individual.

Question 6

What is Spore Formation?

Answer 6

(e.g. of ferns) occurs where special cells with resistant coverings form.

Question 7

What is Parthenogenesis?

Answer 7

(e.g. of bees, wasps) occurs when a new organism develops from an unfertilised egg.

Question 8

What are Runners or Regeneration?

Answer 8

(e.g. of many plants) occurs when part of an organism grows to form other organisms. Examples of regeneration in plants are the vegetative propagation of runners of grasses and strawberries, rhizomes in ferns, tubers in potatoes.

The pistil consists of the sticky stigma, the style (a long tube) and the ovary with ovules

Question 13

angiosperms

Answer 13

Plants that reproduce sexually

Question 14

What are the main parts of the human female reproductive system?

Answer 14

The ovaries, fallopian tube, womb, cervix and vagina.

Question 15

Pollination

Answer 15

Pollination occurs when pollen grains reach the stigma

Question 16

Pollen tube

Answer 16

Pollen grains landing on the sticky stigma develop a long “pollen tube” reaching down the style to the ovule

Question 17

Pollen Gamete

Answer 17

When the pollen tube reaches the ovule the male gamete moves down the tube to fuse with the ovum and produce a zygote

Question 18

Zygote

Answer 18

the fusing of the male gamete with the ovum produces a zygote which develops into a seed

Question 19

Endosperm

Answer 19

the food covering around a plant embryo

Question 20

Germination

Answer 20

the process of a seed growing into a plant

Question 21

scrotum

Answer 21

the bag of skin caontaining the testes

Question 22

testes function

Answer 22

produce male sex cells (sperm)

Question 23

Sperm ducts function

Answer 23

the sperm pass through the sperm ducts and mix with fluids to form semen

Question 24

Answer 24

passes urine and semen out of man’s body

Question 25

urethra function

Answer 25

tube carrying semen and urine

Answer 29

a ring of muscle at the lower end of the uterus which keeps the baby in the womb
