Eukaryotic cells are like complex apartments with rooms (organelles) enclosed by walls (membranes). Prokaryotic cells are like open studios.
Mitosis produces genetically identical cells for regular body functions. Meiosis creates genetically diverse cells for sexual reproduction.
Mitosis is like construction workers in your body. It builds new cells they need to make more of themselves for healing or growth.
Genetic diversity is like having a toolbox with lots of different tools. In living things, these tools are the variations in genes.
What are chloroplasts? You’ll learn about their function, location, structure, and the process of photosynthesis within chloroplasts.
Plants are composed of tissues, which are clusters of cells that work together to perform a function. Learn about plant tissue types & roles.
In biology, we categorize life by how similar organisms are with each other. Like a family tree, we find relationships by their classification of life.
We categorize life into 3 domains of life: eukarya, archaea and bacteria. Domains classify life in the most general way such as the presence of a nucleus.
The Cambrian explosion was the largest diversification of life in Earth’s history. Ocean life started as sparse and simple. Then, it remarkably diversified.
The single-most important biochemical reaction human beings need is cellular respiration. Our cells require oxygen to break down the food and provide energy.
Supernovas are the dying stage of a star when the star explodes. Heavier elements like copper and zinc get flung out into space which we find in our bodies.
By 10 to 1, colonies of bacteria outnumber human cells. We rely on bacteria because they break down sugars, help digest food and protect against infections.
Your identity is decided by 4 letters of DNA (A, T, G & C). And there’s so much Deoxyribonucleic Acid in your body that it stretches all the way to the moon.
