Who this is for: Cambridge IGCSE Biology (0610) students who confuse xylem and phloem transport, or who can name phloem but cannot explain source, sink and sucrose movement in exam wording.
What query it owns: how to use the Translocation of Food 1 flashcard resource in Cambridge IGCSE Biology (0610).
Why this is safe: this page owns the flashcard workflow angle for translocation part 1, while Tutopiya’s Translocation of Food 1 flashcard page owns the card set and the flashcard quiz owns the check.

Translocation of food — the movement of sucrose and amino acids through phloem — is a staple Transport in plants topic in Cambridge IGCSE Biology (0610). Students often say “food moves up and down” without naming phloem, source regions (leaves) or sink regions (roots, fruits). Flashcards fix that when you drill definitions and pathways separately from xylem water transport. This guide shows how to work through Tutopiya’s Translocation of Food 1 flashcard resource.

Key takeaways

• Translocation is the movement of sucrose and amino acids in the phloem.
• Source = where sugars are made (usually leaves); sink = where they are used or stored (roots, fruits, growing tips).
• Transport in phloem requires energy — unlike passive water movement in xylem.
• Follow flashcards with the flashcard quiz and Translocation notes.

What is the Translocation of Food 1 flashcard set?

The Translocation of Food 1 flashcard set covers the foundations of phloem transport in Cambridge IGCSE Biology (0610): phloem structure, what is transported, source-sink relationships and how translocation differs from transpiration. Find it on Tutopiya’s Translocation of Food 1 flashcard page alongside Translocation notes and Xylem and Phloem.

Xylem vs phloem: what each flashcard pair should lock in

Feature	Xylem	Phloem
What is transported	Water and mineral ions	Sucrose, amino acids
Direction	Upward (mainly)	Up and down (source to sink)
Process linked	Transpiration pull	Translocation
Energy needed	No (passive pull)	Yes (from respiration)

How to use the flashcards — step by step

1. Skim Translocation notes first.
2. Open the flashcard deck — 10–15 cards per session.
3. Answer before flipping — include tissue name and substance transported.
4. Sort into three piles — confident / unsure / wrong.
5. Re-drill unsure and wrong the same day.
6. Take the flashcard quiz.
7. Continue with Translocation of Food 2 flashcard for mechanism detail.

Flashcard prompts in past-paper wording

Exam-style prompt	Must-include keywords	Common error
”Define translocation.”	Sucrose/amino acids, phloem	Saying “food” without naming phloem
”State the function of phloem.”	Transport assimilates, source to sink	Confusing with xylem
”Name a source and a sink in a plant.”	Leaves (source), roots/fruits (sink)	Both called “source"
"Compare xylem and phloem.”	Substance, direction, energy	Only naming structure
”Explain why translocation needs energy.”	Active process, loading phloem	Saying it is passive

Worked recall drills (say these aloud on each card)

1. Card front: “Define translocation.” Back: The movement of sucrose and amino acids through the phloem from source to sink.
2. Card front: “Source and sink in summer?” Back: Source = leaves (photosynthesis); sinks = roots, fruits, growing tips (respiration, storage, growth).
3. Card front: “Xylem vs phloem — what moves?” Back: Xylem = water and minerals; phloem = sucrose and amino acids.

Confirm with the Translocation quiz.

How flashcards fit the wider Transport in plants unit

Part 1 flashcards build vocabulary; Translocation of Food 2 flashcard covers loading and the pressure-flow model. Link back to Transpiration for the water pathway. The Cambridge IGCSE Biology resource hub links all Transport resources.

Common mistakes students make with flashcards

• Using “food” without specifying sucrose or amino acids.
• Confusing translocation with transpiration.
• Saying phloem transport is passive — it requires energy.
• Forgetting that direction is source to sink, not always upward.
• Skipping Part 2 flashcards before topical past papers.

When you need more support

If compare xylem/phloem questions still fail, book a Cambridge IGCSE Biology tutor, then repeat the flashcard quiz.

Frequently asked questions

How often should I use the Translocation of Food 1 flashcards? Two sessions per week until source-sink and phloem definitions are automatic.

Should I do Part 1 before Part 2? Yes — Part 1 builds definitions; Part 2 covers the mechanism in more depth.

Are flashcards enough for compare questions? They lock in facts; practise compare stems on the Transport in plants topical past paper questions.

What is transported in phloem? Mainly sucrose and amino acids — not water (xylem) or starch (too large; starch is converted to sucrose first).
