How are relationships or interactions between different organelles illustrated? What is missing from this model? Evaluating different models helps learners better appreciate and understand the nuanced ...

sensing mechanical forces and directing when to build or break down bone. But when exposed to senescent cells—damaged cells that stop dividing but don't die—osteocytes themselves begin to stiffen.

which lacked the organelles, with stem cells sourced from bone marrow. With the stem cells’ mitochondria tagged with fluorescent proteins, the team shot a time-lapse video of what happened next.

Eukaryotic cells contain a large number of functional sub-units, so-called organelles. They perform important functions ...
