Yeast cells have a cell wall, like plant cells, but no chloroplasts. Yeast can reproduce by producing a bud. The bud grows until it is large enough to split from the parent cell as a new yeast cell.

The fundamental problem of how cells reproduce has been studied intensely ever since dividing cells were first observed by microscopy. Since, the discovery in the seventies and eighties of the ...

In most multicellular organisms, meiosis is restricted to germ cells that are set aside in early development. The germ cells reside in specialized environments provided by the gonads, or sex organs.

Take the evolution of sex, for instance. To make the move from asexual to sexual reproduction, nature took a system by which parent cells reproduced simply by dividing (asexual reproduction ...

Our bodies divest themselves of 60 billion cells every day through a natural process of cell culling and turnover called apoptosis.

Not all mutations that lead to cancerous cells result in the cells reproducing at a faster, more uncontrolled rate. For example, a mutation may simply cause a cell to keep from self-destructing.

Researchers at Kumamoto University have achieved a groundbreaking advancement in stem cell biology by reproducing the developmental process of hematopoietic stem cells (HSCs) in vitro. This culture ...
