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 sugars, such as sucrose, produced during photosynthesis, to other areas of the plant for respiration or storage.

Where does translocation occur in a plant?

Translocation occurs in the phloem, which is one of the two main types of transport tissue in the vascular bundle.

What are ‘sources’ and ‘sinks’ in the context of translocation?

The ‘source’ is where substances like sugars are produced or enter, and the ‘sink’ is the area of growth or storage where these substances are transported.

How do the roles of sources and sinks change during the summer?

In the summer, the leaves act as the source, producing excess sugars, and the roots act as the sink, storing these sugars.

How do the roles of sources and sinks change during the winter and spring?

In the winter and spring, the roots act as the source, providing stored sugars, while the leaves act as the sink, receiving sugars for growth.

What role do companion cells play in translocation?

Companion cells provide energy for sieve cells, which are involved in the transport of substances during translocation.
