Question 1

What is puberty?
  1. The stage when a child’s body matures into an adult body
  2. The process of fertilisation in the uterus
  3. The release of an egg from the oviduct
  4. The stage when growth stops completely

Question 2

Which is the male gamete in humans?
  1. Sperm cell
  2. Egg cell
  3. Embryo
  4. Placenta

Question 3

Which is the female gamete in humans?
  1. Egg cell
  2. Sperm cell
  3. Zygote
  4. Foetus

Question 4

What is fertilisation?
  1. Fusion of the nuclei of a sperm cell and an egg cell
  2. Release of an egg from an ovary
  3. Attachment of an embryo to the uterine lining
  4. Division of a zygote into two gametes

Question 5

Where does fertilisation usually happen in humans?
  1. Oviduct (fallopian tube)
  2. Uterus
  3. Ovary
  4. Cervix

Question 6

Where does implantation of the embryo occur?
  1. In the lining of the uterus
  2. In the oviduct
  3. In the ovary
  4. In the cervix

Question 7

What is the main role of the placenta during pregnancy?
  1. To exchange substances between mother and foetus
  2. To produce sperm for the foetus
  3. To digest food for the mother
  4. To replace the umbilical cord

Question 8

Why can smoking during pregnancy harm the foetus?
  1. It can reduce oxygen reaching the foetus
  2. It guarantees twins
  3. It increases nutrient transfer to the foetus
  4. It prevents the placenta from forming

Question 9

How long does a full-term human pregnancy last?
  1. \(40\,\mathrm{weeks}\)
  2. \(4\,\mathrm{weeks}\)
  3. \(20\,\mathrm{weeks}\)
  4. \(80\,\mathrm{weeks}\)

Question 10

What is ovulation?
  1. Release of an egg cell from an ovary
  2. Fusion of sperm and egg nuclei
  3. Shedding of the uterine lining
  4. Development of a foetus in the uterus

Question 11

What is the main purpose of the menstrual cycle?
  1. To prepare the reproductive system for possible pregnancy
  2. To release sperm from the testes
  3. To prevent any egg from maturing
  4. To digest food more quickly

Question 12

Which structure carries sperm from the testes?
  1. Sperm duct
  2. Oviduct
  3. Uterus
  4. Placenta

Question 13

What is pollination in flowering plants?
  1. Transfer of pollen from anther to stigma
  2. Fusion of male and female nuclei in an ovule
  3. Growth of a seed into a new plant
  4. Transfer of water from roots to leaves

Question 14

Which feature is typical of insect-pollinated flowers?
  1. Bright petals and nectar
  2. Small dull petals and exposed anthers
  3. Feathery stigma hanging outside
  4. No scent and no nectar

Question 15

Which feature is typical of wind-pollinated flowers?
  1. Feathery stigma and exposed anthers
  2. Large scented petals and sticky nectar
  3. Bright petals with little pollen
  4. Petals sealed shut to trap pollen

Question 16

Where does fertilisation occur in a flowering plant?
  1. In the ovule
  2. In the stigma
  3. In the anther
  4. In the petal

Question 17

After fertilisation in a flowering plant, what does the ovule develop into?
  1. Seed
  2. Petal
  3. Stigma
  4. Sepal

Question 18

After fertilisation in a flowering plant, what does the ovary develop into?
  1. Fruit
  2. Root
  3. Leaf
  4. Anther

Question 19

Why is seed dispersal important for plants?
  1. It reduces competition between offspring and parent plants
  2. It ensures all seeds grow beside the parent
  3. It prevents seeds from being fertilised
  4. It makes pollination unnecessary

Question 20

A dandelion seed has a parachute-like structure. Which dispersal method is this adapted for?
  1. Wind dispersal
  2. Animal ingestion
  3. Explosive dispersal
  4. Water dispersal
