Your own biology definitions, not a generic list

Ready-made lists of biology definitions are useful for a quick look, but they rarely match the exact wording your instructor uses in lecture or on exams.

Generate cards from the exact chapter or slides your class uses.
Correct any definition that differs from your course wording before you study.
Review missed terms on a spaced schedule instead of rereading the whole chapter.
Start free with no credit card, then export to Anki or CSV on Plus if you need them.

Example biology definitions flashcards

OsmosisMovement of water across a semipermeable membrane from an area of lower solute concentration to one of higher solute concentration.

MitosisCell division that produces two genetically identical daughter cells, each with the same number of chromosomes as the parent.

HomeostasisThe maintenance of a stable internal environment, such as body temperature or blood glucose, despite changes outside the organism.

AlleleAn alternative form of a gene that occupies the same locus on a chromosome as other forms of that gene.

Built from your material

Upload PDF textbook chapters, PPTX lecture slides, DOCX notes, plain text or a photo of a page.

Spaced repetition

Cards you miss come back sooner, so you spend less time on terms you already know.

Quizzes and mind maps too

Test yourself with multiple choice, true/false and short answer questions, or map how terms connect.

How it works

Upload your notes

Add a chapter, slide deck, document or photo of a page from your class.

Review the generated cards

Check the terms and definitions the AI pulled out and edit anything that does not match your course.

Study on a schedule

Work through the cards in the browser and let spaced repetition bring back the ones you miss.

DeckOwl builds flashcards from the material you already have. Upload a PDF of your textbook chapter, PPTX lecture slides, DOCX notes, or a photo of a page, and the AI extracts the key terms with their definitions for you to review.

Spaced repetition then schedules the cards you get wrong more often, so terms like mitosis and osmosis stay with you. The free plan includes 3 generations a month and browser study, and exports to Anki and CSV are on Plus.

Frequently asked questions

How many biology definitions should I memorize before an exam?

Start with the terms your instructor stressed in lecture and the bolded words in your textbook chapter. Reviewing 20 to 40 terms per session with spaced repetition usually works better than one long cram.

What is the best way to study biology definitions?

Write the term on one side and a definition in your own words on the other, then test yourself before checking. Revisit the cards you missed the next day and again a few days later.

Can I use my own notes instead of a ready-made list?

Yes. You can upload PDFs, DOCX files, PPTX slides, plain text or photos of pages, and DeckOwl will generate flashcards from that material.

Can I export my biology flashcards?

PDF, DOCX, Anki and CSV exports are part of the Plus plan, which costs $99.90 a year or $9.99 a month. The free plan lets you study in the browser with 3 generations per month.
