Translocation Flashcards

1️⃣ Familiarise yourself with the flashcards:

Look through all the flashcards to see what's on both sides.
Make sure you understand the information on each card. If something's unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

Look at the question or prompt on each card and try to remember the answer before flipping it over.
Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It's useful to remember specific examples to understand these concepts better.

What is translocation in plants?

Translocation is the movement of dissolved food, such as sugars, through the phloem.

Translocation happens in the phloem tubes.

Translocation mainly moves dissolved sugars, especially sucrose.

Translocation can move substances both up and down the plant.

A source is a part of the plant that makes or releases sugars into the phloem, such as leaves.

A sink is a part of the plant that uses or stores sugars, such as roots, fruits, or seeds.

Plants need translocation to move sugars from leaves to other parts for respiration, growth, and storage.

Translocation is an active process because it needs energy from respiration in phloem cells.

A leaf that is doing photosynthesis is a source, because it makes sugars.

A growing root tip is a sink, because it needs sugars for growth.

Translocation moves sugars in the phloem both up and down; transpiration moves water in the xylem mainly upwards.
