Animal & plant life cycles
Take your time. Show your thinking.
1. What is the correct life cycle of a frog (an amphibian) in order: Frogspawn (eggs) → Tadpole → Froglet (with legs) → Adult frog, or Tadpole → Egg → Adult frog?
Egg → Larva → Pupa → Adult
2. How do mammals (such as humans, dolphins, cats and whales) feed their newborn young: the mother produces milk from mammary glands, or newborn mammals photosynthesis?
Egg → Larva → Pupa → Adult
3. In the life cycle of a butterfly, what is the resting casing inside which the caterpillar transforms into a winged adult: the chrysalis (pupa) or the seed?
Egg → Larva → Pupa → Adult
4. What is the transfer of pollen grains from the male anther of a flower to the female stigma called: pollination or germination?
Egg → Larva → Pupa → Adult
5. What do we call the complete biological change in body form that a caterpillar goes through to become a butterfly, or a tadpole to become a frog: metamorphosis or hibernation?
Egg → Larva → Pupa → Adult
6. In the life cycle of a butterfly, what is the feeding stage that hatches from the egg and eats leaves to grow rapidly: the caterpillar (larva) or the pupa?
Egg → Larva → Pupa → Adult
7. In a bird-pollinated or insect-pollinated flower, why are the petals often brightly coloured and scented with sweet nectar: to attract pollinators such as bees, butterflies and sunbirds, or to scare away the Sun?
Egg → Larva → Pupa → Adult
8. Inside a bird’s egg, what part provides the main store of nutrient-rich food for the growing embryo: the yolk (and albumen) or the outer shell?
Egg → Larva → Pupa → Adult
9. Where do female sea turtles return to lay their clutches of leathery eggs: in a nest dug in the warm sand of a beach above the high-tide line, or floating on the waves?
Egg → Larva → Pupa → Adult
10. After pollen lands on the stigma and travels down to join with an ovule inside the flower’s ovary, what is this fusion of male and female cells called: fertilisation or transpiration?
Egg → Larva → Pupa → Adult
11. In a flowering plant’s life cycle, what is the process called when a seed absorbs water, swells and begins to sprout a root and shoot: germination or pollination?
Egg → Larva → Pupa → Adult
12. What three conditions do almost all seeds need in order to germinate successfully: water, oxygen and a suitable temperature (warmth), or bright electric light and salt?
Egg → Larva → Pupa → Adult

Animal & plant life cycles
Answers and reasoning. Review before teaching.
1. What is the correct life cycle of a frog (an amphibian) in order: Frogspawn (eggs) → Tadpole → Froglet (with legs) → Adult frog, or Tadpole → Egg → Adult frog?
Frogs lay jelly-coated eggs in water that hatch into gill-breathing tadpoles before growing legs and lungs.
2. How do mammals (such as humans, dolphins, cats and whales) feed their newborn young: the mother produces milk from mammary glands, or newborn mammals photosynthesis?
The mother produces milk from mammary glands
All mammals nourish their young with nutrient-rich milk.
3. In the life cycle of a butterfly, what is the resting casing inside which the caterpillar transforms into a winged adult: the chrysalis (pupa) or the seed?
Chrysalis (pupa)
Inside the chrysalis (pupa), tissues reorganise into the adult butterfly.
4. What is the transfer of pollen grains from the male anther of a flower to the female stigma called: pollination or germination?
Pollination
Pollination can be carried out by insects, birds, bats or the wind.
5. What do we call the complete biological change in body form that a caterpillar goes through to become a butterfly, or a tadpole to become a frog: metamorphosis or hibernation?
Metamorphosis
Metamorphosis is a dramatic transformation in body structure from larva to adult.
6. In the life cycle of a butterfly, what is the feeding stage that hatches from the egg and eats leaves to grow rapidly: the caterpillar (larva) or the pupa?
Caterpillar (larva)
The caterpillar is the larval stage specialised for feeding and growth.
7. In a bird-pollinated or insect-pollinated flower, why are the petals often brightly coloured and scented with sweet nectar: to attract pollinators such as bees, butterflies and sunbirds, or to scare away the Sun?
To attract pollinators such as bees, butterflies and sunbirds
As pollinators feed on nectar, pollen brushes onto their bodies and is carried to the next flower.
8. Inside a bird’s egg, what part provides the main store of nutrient-rich food for the growing embryo: the yolk (and albumen) or the outer shell?
The yolk (and albumen)
The egg yolk is packed with fats, proteins and vitamins that nourish the developing chick.
9. Where do female sea turtles return to lay their clutches of leathery eggs: in a nest dug in the warm sand of a beach above the high-tide line, or floating on the waves?
In a nest dug in the warm sand of a beach above the high-tide line
Female sea turtles crawl ashore at night to bury their eggs in sandy beaches; hatchlings then scramble to the sea.
10. After pollen lands on the stigma and travels down to join with an ovule inside the flower’s ovary, what is this fusion of male and female cells called: fertilisation or transpiration?
Fertilisation
After fertilisation, the ovule develops into a seed and the surrounding ovary swells into a fruit.
11. In a flowering plant’s life cycle, what is the process called when a seed absorbs water, swells and begins to sprout a root and shoot: germination or pollination?
Germination
Germination is the sprouting of a seed into a seedling.
12. What three conditions do almost all seeds need in order to germinate successfully: water, oxygen and a suitable temperature (warmth), or bright electric light and salt?
Water, oxygen and a suitable temperature (warmth)
Seeds use stored food reserves to germinate underground and do not need light until their first leaves emerge for photosynthesis.
