Who this is for: Cambridge IGCSE Biology (0610) students who have mastered basic translocation definitions but still lose marks on explain questions about phloem loading, mass flow and companion cells.
What query it owns: how to use Translocation of Food 2 flashcards effectively in Cambridge IGCSE Biology.
Why this is safe: this page owns the advanced flashcard-study-method angle, while Tutopiya’s Translocation of Food 2 flashcard resource owns the card deck and the flashcard quiz owns the practice check.

Translocation of Food 2 flashcards build on the first deck by training mechanism-level recall: companion cells, active loading at the source, mass flow through sieve tubes, and unloading at sinks. Cambridge IGCSE Biology (0610) explain questions demand named structures and a logical sequence — not just “sugars move in phloem.” This guide shows how to use the second translocation flashcard deck for those higher-mark stems.

Key takeaways

• Companion cells provide energy for loading sucrose into sieve tubes at the source.
• Mass flow moves dissolved sugars through phloem along a pressure gradient from source to sink.
• Unloading at the sink lowers pressure, maintaining flow — bidirectional transport is possible in different sieve tubes.
• Complete Translocation of Food 1 flashcards before this deck.
• Confirm recall with the Translocation of Food 2 flashcard quiz.

What are Translocation of Food 2 flashcards?

Translocation of Food 2 flashcards cover phloem structure, loading, mass flow and unloading — the mechanism layer beyond definitions. Tutopiya’s Translocation of Food 2 flashcard deck targets Cambridge IGCSE Biology (0610) Extended Transport in Plants explain questions.

How to use the flashcards — step by step

1. Prerequisite check — pass Translocation of Food 1 quiz before opening this deck.
2. Study companion cell cards — link to active loading and energy from respiration.
3. Sequence cards — loading → high pressure at source → mass flow → unloading at sink.
4. Explain cards aloud — full sentences, not single-word answers.
5. Repair from Translocation notes, then take the flashcard quiz.

High-value flashcard prompts mapped to exam wording

Flashcard front (exam stem)	Back must include	Command word tested
”Describe how sucrose is loaded into phloem.”	Companion cells; active transport; sieve tubes	Describe
”Explain mass flow in phloem.”	High pressure at source; flow to sink; unloading	Explain
”State the role of companion cells.”	Loading sucrose; provide energy/ATP	State
”Suggest effect of ring-barking a tree trunk.”	Phloem removed; sugars cannot reach roots; root death	Suggest
”Compare loading and unloading.”	Source vs sink; pressure changes	Compare

Worked recall stems (how flashcards should train you)

1. Card: “Explain how translocation occurs in phloem.” Target: sucrose actively loaded into sieve tubes at source → water enters by osmosis → high pressure → mass flow to sink → unloading lowers pressure. Missing osmosis/pressure? — repeat mechanism sequence card.
2. Card: “Describe the role of companion cells in translocation.” Target: companion cells adjacent to sieve tubes; provide energy for active loading of sucrose. If you only said “help phloem” — review structure on Xylem and Phloem notes.
3. Card: “Suggest why removing bark around a tree trunk kills the tree.” Target: phloem in bark transports sugars to roots; without phloem, roots cannot respire and the tree dies. Reward in exams: named tissue + consequence chain.

Mass flow mechanism — one summary card

Step	Location	What happens
1. Loading	Source (e.g. leaf)	Sucrose actively loaded into sieve tubes; water follows by osmosis
2. High pressure	Source end	Water influx creates pressure
3. Mass flow	Sieve tubes	Dissolved sugars pushed along phloem
4. Unloading	Sink (e.g. root)	Sugars removed; pressure drops; flow continues

Test this four-step sequence from memory every session.

Common mistakes students make with flashcards

• Describing translocation as passive diffusion — loading requires active transport and energy.
• Omitting companion cells in explain answers.
• Confusing ring-barking (phloem damage) with xylem cutting (water transport).
• Skipping the first deck — mechanism cards fail without source/sink foundations.
• Never taking the Translocation of Food 2 quiz.

When you need more support

If explain stems on phloem mechanism still fail, book a Cambridge IGCSE Biology tutor. Use the Cambridge IGCSE Biology resource hub for the full Transport in Plants unit.

Frequently asked questions

Do I need Translocation of Food 1 before this deck? Yes — the second deck assumes you know definitions, source/sink and xylem vs phloem contrasts.

What is the hardest card type in this deck? Full explain sequences linking loading, pressure and mass flow — practise aloud, not silently.

How does this deck connect to ring-barking questions? Ring-barking removes phloem in bark; the suggest/explain cards train the consequence chain examiners reward.

How do I know flashcards are working? You pass the Translocation of Food 2 flashcard quiz on mechanism and explain prompts.
