Plants, leaves & photosynthesis
Take your time. Show your thinking.
1. What is the role of the green sepals on the outside of a flower bud: to protect the unopened flower bud, or to absorb soil nitrates?
2. What is the transfer of pollen from the anther (male part) to the stigma (female part) of a flower called: pollination or germination?
3. Why do plants need nitrate ions from the soil: to make amino acids and proteins for cell growth, or to freeze water?
4. Which three conditions do most seeds need to germinate: water, oxygen and warmth, or darkness, ice and salt?
5. What chemical reagent turns blue-black when added to a leaf that contains stored starch: iodine solution or pure water?
6. Which part of a flower produces and holds the pollen grains: the anther (stamen) or the sepal?
7. Which vascular tissue consists of hollow tubes that carry water and dissolved mineral ions upward from the roots to the leaves: xylem or petals?
8. Which vascular tissue carries sugars made in the leaves to the rest of the plant: phloem or bark?
9. What green pigment inside plant chloroplasts absorbs light energy for photosynthesis: chlorophyll or haemoglobin?
10. Which part of the plant transports water upward from the roots and supports the leaves and flowers: the stem or the seed coat?
11. Why do many insect-pollinated flowers have brightly coloured petals and sweet nectar: to attract pollinators, or to absorb soil water?
12. How are coconut seeds adapted to travel between tropical islands: they float on ocean currents, or they attach to bird feathers?

Plants, leaves & photosynthesis
Answers and reasoning. Review before teaching.
1. What is the role of the green sepals on the outside of a flower bud: to protect the unopened flower bud, or to absorb soil nitrates?
To protect the unopened flower budSepals enclose and protect the developing petals before the flower opens.
2. What is the transfer of pollen from the anther (male part) to the stigma (female part) of a flower called: pollination or germination?
PollinationPollination transfers pollen grains by insects, birds or wind so fertilisation can occur.
3. Why do plants need nitrate ions from the soil: to make amino acids and proteins for cell growth, or to freeze water?
To make amino acids and proteins for cell growthPlants combine glucose with nitrogen from nitrates to synthesise amino acids and proteins.
4. Which three conditions do most seeds need to germinate: water, oxygen and warmth, or darkness, ice and salt?
Water, oxygen and warmthSeeds require water to activate enzymes, oxygen for respiration, and suitable warmth.
5. What chemical reagent turns blue-black when added to a leaf that contains stored starch: iodine solution or pure water?
Iodine solutionYellow-brown iodine solution turns blue-black in the presence of starch.
6. Which part of a flower produces and holds the pollen grains: the anther (stamen) or the sepal?
Anther (stamen)The stamen is the male part of the flower, consisting of a filament supporting the pollen-producing anther.
7. Which vascular tissue consists of hollow tubes that carry water and dissolved mineral ions upward from the roots to the leaves: xylem or petals?
XylemXylem vessels transport water and minerals in a one-way flow from roots to leaves.
8. Which vascular tissue carries sugars made in the leaves to the rest of the plant: phloem or bark?
PhloemPhloem translocates dissolved sugars from leaves to growing roots, fruits and seeds.
9. What green pigment inside plant chloroplasts absorbs light energy for photosynthesis: chlorophyll or haemoglobin?
ChlorophyllChlorophyll absorbs mainly red and blue light and reflects green light.
10. Which part of the plant transports water upward from the roots and supports the leaves and flowers: the stem or the seed coat?
StemXylem vessels in the stem transport water and minerals upward to the leaves.
11. Why do many insect-pollinated flowers have brightly coloured petals and sweet nectar: to attract pollinators, or to absorb soil water?
To attract pollinatorsBees and butterflies visit for nectar and carry pollen between flowers.
12. How are coconut seeds adapted to travel between tropical islands: they float on ocean currents, or they attach to bird feathers?
They float on ocean currentsA coconut’s fibrous, air-filled husk makes it buoyant and waterproof in seawater.
