General structure
Name the part of the flower that is brightly coloured and attracts pollinators.
Petals
Pollen is produced here.
Anther
Two raw materials required for photosynthesis.
Carbon dioxide and water (and light).
Define transpiration.
Loss of water vapour from plant leaves (mainly through stomata).
Structure that anchors the plant.
Roots
Structure pollen lands on during pollination.
Stigma
Two raw materials required for respiration.
Oxygen and Glucose
Where on the leaf does most transpiration occur?
Through stomata (usually on underside of leaves).
Structure that protects the developing bud.
Sepal
Structure fertilisation occurs in a flowering plant.
In the ovule inside the ovary of the flower.
Identify the organelle in leaf cells where photosynthesis happens.
Chloroplasts (chlorophyll in leaf cells).
What is the role of the waxy cuticle on the leaf surface?
waterproof layer that allows light through but reduces water loss.
Name three labeled parts of a leaf.
Examples: cuticle, palisade mesophyll, spongy mesophyll, stomata, guard cells, vascular bundle/xylem/phloem, upper/lower epidermis, blade, vein.
Describe the role of pollen tubes in fertilisation.
Pollen tube grows from stigma through style to ovule, delivering sperm nuclei.
Identify the organelle in leaf cells where respiration happens.
These leaf adaptations all serve this function in plants. (Thick cuticles, small leaves, hairy leaves and closed guard cells.)
Reduce water loss.
Name the two main plant transport tissues and state what each transports.
Xylem (transports water and minerals) and phloem (transports dissolved sugars/products of photosynthesis).
Describe the difference between self‑pollination and cross‑pollination.
Self‑pollination: pollen to same flower/plant; cross‑pollination: pollen to different plant—cross increases genetic diversity.
Describe what happens to glucose produced in photosynthesis.
Glucose is used for respiration (energy) or converted to starch for storage.
What role do Guard cells have during transpiration?
Guard cells open stomata to allow CO₂ in; when open water vapour diffuses out—in drought guard cells close to conserve water.
