Question 1 of 25
The process of producing new individuals of one's own kind is called:
Respiration
Reproduction
Digestion
Excretion
Explanation: Reproduction is the production of young ones similar to the parents.
Question 2 of 25
Asexual reproduction involves how many parents?
One
Two
Three
Four
Explanation: Asexual reproduction involves only a single parent.
Question 3 of 25
The fusion of a male sex cell and a female sex cell is called:
Pollination
Fertilisation
Germination
Budding
Explanation: Fertilisation is the fusion of male and female sex cells in sexual reproduction.
Question 4 of 25
Offspring produced by asexual reproduction are usually:
Identical to the parent
Different from the parent
Always larger
Always smaller
Explanation: With one parent and no mixing, asexual offspring are identical to the parent.
Question 5 of 25
Reproduction is important mainly because it:
Provides food
Continues the species
Removes waste
Produces energy
Explanation: Reproduction continues the species, as individuals do not live forever.
Question 6 of 25
Growing a new plant from a root, stem, or leaf of the parent is called:
Pollination
Vegetative propagation
Fertilisation
Germination
Explanation: Vegetative propagation grows a new plant from a part of the parent plant.
Question 7 of 25
Yeast reproduces asexually by:
Spore formation
Budding
Fragmentation
Cuttings
Explanation: Yeast forms a bud that grows into a new individual — budding.
Question 8 of 25
Bread mould and ferns reproduce by forming many tiny:
Buds
Spores
Cuttings
Seeds
Explanation: Bread mould and ferns reproduce by spore formation.
Question 9 of 25
The green alga Spirogyra reproduces by breaking into pieces, a method called:
Budding
Fragmentation
Vegetative propagation
Pollination
Explanation: Spirogyra reproduces by fragmentation, each piece growing into a new filament.
Question 10 of 25
A new plant grown from a potato develops from the potato's:
Seed
Bud (eye)
Flower
Fruit
Explanation: A potato grows a new plant from its bud, known as the "eye".
Question 11 of 25
The male reproductive part of a flower is the:
Pistil
Stamen
Sepal
Petal
Explanation: The stamen is the male part, producing pollen in its anther.
Question 12 of 25
Pollen grains are produced in the part of the stamen called the:
Stigma
Anther
Ovary
Style
Explanation: The anther at the top of the stamen produces pollen grains.
Question 13 of 25
The transfer of pollen from the anther to the stigma is called:
Fertilisation
Pollination
Germination
Budding
Explanation: Pollination is the transfer of pollen from anther to stigma.
Question 14 of 25
After fertilisation, the ovule develops into a:
Fruit
Flower
Seed
Petal
Explanation: The fertilised ovule develops into a seed.
Question 15 of 25
The part of the flower that develops into a fruit after fertilisation is the:
Ovary
Stigma
Petal
Sepal
Explanation: The ovary develops into a fruit that encloses the seeds.
Question 16 of 25
A seed contains a store of food and a:
Flower
Baby plant (embryo)
Fruit
Root hair
Explanation: A seed contains a baby plant (embryo) and stored food in a protective coat.
Question 17 of 25
The spreading of seeds away from the parent plant is called:
Pollination
Seed dispersal
Fertilisation
Germination
Explanation: Seed dispersal is the scattering of seeds to new places.
Question 18 of 25
The coconut is a seed that is dispersed mainly by:
Wind
Water
Animals
Explosion
Explanation: The coconut floats and is dispersed by water.
Question 19 of 25
Seeds with hooks that stick to an animal's fur are dispersed by:
Wind
Water
Animals
Explosion
Explanation: Hooked seeds cling to fur and are carried away by animals.
Question 20 of 25
Seed dispersal is necessary mainly to prevent:
Photosynthesis
Overcrowding of plants
Pollination
Germination
Explanation: Dispersal prevents overcrowding and competition under the parent plant.
Question 21 of 25
The male sex cell in animals is the:
Egg
Sperm
Ovule
Zygote
Explanation: The male sex cell in animals is the sperm; the female sex cell is the egg.
Question 22 of 25
The cell formed by the fusion of a sperm and an egg is the:
Bud
Spore
Zygote
Ovule
Explanation: Fertilisation forms a zygote, which develops into a new individual.
Question 23 of 25
Animals that lay eggs from which young hatch are called:
Viviparous
Oviparous
Mammals
Asexual
Explanation: Oviparous animals lay eggs; examples include birds and frogs.
Question 24 of 25
Animals that give birth to live young are called:
Oviparous
Viviparous
Spore-forming
Budding
Explanation: Viviparous animals give birth to live young, e.g. humans and most mammals.
Question 25 of 25
Amoeba reproduces asexually by dividing into two, a method called:
Budding
Binary fission
Fragmentation
Pollination
Explanation: Amoeba reproduces by binary fission, splitting into two new individuals.
