Example high school biology flashcards

Which organelle produces most of a cell's ATP?The mitochondrion, through cellular respiration, because it houses the enzymes of the Krebs cycle and the electron transport chain.

What is the function of ribosomes?They build proteins by translating mRNA into a chain of amino acids, so they are where translation happens.

What is osmosis?The diffusion of water across a semipermeable membrane, moving from the side with lower solute concentration to the side with higher solute concentration.

What does one turn of the citric acid cycle produce per acetyl-CoA?3 NADH, 1 FADH2, 1 ATP or GTP and 2 CO2, which is why the cycle feeds the electron transport chain.

How do mitosis and meiosis differ?Mitosis produces two genetically identical diploid cells, while meiosis produces four genetically varied haploid gametes, which is why it is used for reproduction.

Generate the full set

Works with the files you already have

Upload PDF, DOCX, PPTX, plain text or images. Photos of pages are read with text recognition, so you do not need to retype anything.

Spaced repetition built in

Cards you miss come back sooner and cards you know come back later, so review time goes to the material you are still learning.

Quizzes and mind maps too

Turn the same material into multiple choice, true or false and short answer quizzes with explanations, or into a mind map of the main ideas.

How it works

Upload your material

Drop in a PDF, slide deck, Word document, set of notes or a photo of a page. No credit card is needed to start.

Review the generated cards

Read through the flashcards, edit any that are unclear, and remove the ones you do not need before you begin studying.

Study on a schedule

Work through the deck in the browser. Spaced repetition decides when each card comes back based on how well you knew it.

Writing cards by hand is slow, and cards copied straight from a textbook often test trivia instead of the ideas that matter. Generating them from your own lecture material keeps the deck tied to what your instructor actually covers, and you can edit any card that misses the point.

Once the cards exist, spaced repetition handles the scheduling. You spend less time deciding what to review and more time answering the cards you still miss.

Frequently asked questions

How many flashcards should I make for a biology unit?

Focus on one idea per card rather than aiming for a set number. Cards for key terms, processes and comparisons tend to cover a unit better than long cards that bundle several facts together.

What makes a good flashcard for studying?

A good card asks one specific question with one clear answer, and you should be able to say the answer in your own words. If a card has two answers, split it into two cards so you can tell which part you forgot.

Is there a free way to try it?

The free plan includes 3 generations per month and lets you study in the browser. Exporting to PDF, DOCX, Anki or CSV requires the Plus plan, which is $39 per year or $7.99 per month.

Can I export my flashcards to Anki?

Yes, Anki export is included with the Plus plan, along with PDF, DOCX and CSV export. Students can get 40% off with a school email address.
