Chloroplasts 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 a chloroplast?

A green part in plant and algal cells. It does photosynthesis.

Which cells contain chloroplasts?

Plant cells and algal cells. Animal cells do not have them.

What pigment is found in chloroplasts?

Chlorophyll. It absorbs light energy for photosynthesis.

Why do chloroplasts look green?

Because chlorophyll reflects green light and absorbs red and blue.

What is the main job of chloroplasts?

To absorb light and make glucose by photosynthesis.

Where in a leaf are most chloroplasts found?

In palisade mesophyll cells near the top of the leaf.

Why do palisade cells have many chloroplasts?

They get the most light, so more chloroplasts help make more glucose.

Why do most root cells not have chloroplasts?

They are underground. They get little light, so they do not photosynthesise.

How are chloroplasts adapted for photosynthesis?

They have chlorophyll and many folded membranes. This gives a large surface area to catch light.

What stores may form inside chloroplasts after photosynthesis?

Starch grains. They form when extra glucose is stored.
