Biology · The cell
[0:00] Today we're looking at the cell, the basic unit of life. There are two main groups: prokaryotes, like bacteria, have no defined nucleus…
Board · Biology

Key points
- Every living thing is made of one or more cells.
- Prokaryote: no defined nucleus. E.g. bacteria.
- Eukaryote: nucleus with DNA. Plants, animals and fungi.
- Mitochondria produce the energy.
Exam tip If they ask for the short definition: “the basic unit of life”.
The cell
What's the difference between a prokaryotic and a eukaryotic cell?
Tap to see the answer
Answer
A prokaryotic cell has no defined nucleus; a eukaryotic cell does, and the DNA sits inside it.
NoYes
What does the membrane do?
How it works
From lecture to exam, in three steps.
No rewriting your notes, no copying them out neatly. You record, ROBI builds the material, you practice.
-
01
Record or upload a PDF
Leave your phone recording in class, or while you listen to a Zoom lecture. Got the handout? Import the PDF.

02
ROBI builds your board
It transcribes live and organizes everything by topic and depth: summary, key points, concept map, flashcards and quiz.

03
Study actively
Practice with cards and questions built from what was actually said in class, and ask the chat about anything that wasn't clear.
The board
Everything you need to study, built for you.
Every recording becomes a board with tools to review however works best for you. Try them right here.
Summaries by topic and depth
A quick view to review, or a deeper one to really understand.
1. What a cell is
The basic unit of life. There are prokaryotes (no nucleus) and eukaryotes (with a nucleus).
2. Parts of the cell
Membrane, cytoplasm, nucleus and mitochondria.
3. For the exam
Be able to tell prokaryotes and eukaryotes apart, with an example of each.
1.1 The unit of life
The cell is the smallest unit that carries out the functions of a living thing: it feeds, interacts with its surroundings and can reproduce.
- Unicellular: a single cell does everything, like many bacteria.
- Multicellular: many specialized cells, like in the human body.
1.2 Prokaryotes and eukaryotes
Prokaryotes have no defined nucleus. Eukaryotes do: the DNA is inside the nucleus.
1.3 Membrane and cytoplasm
The membrane decides what goes in and out. The cytoplasm holds the mitochondria, which produce the energy.
