Plant cells have several structures not found in other eukaryotes. In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls ...

By this definition, stem cells are particularly important for plant growth, because virtually all tissues of the plant descend from small groups of stem cells located in their growing apices ...

Using a computer model that reveals how plants grow thicker over time, biologists have uncovered how cells are activated to produce wood tissue. Understanding the genetic and molecular signals behind ...

A palisade cell is packed with chloroplasts for photosynthesis. A xylem cell is a long, thin, straw-like waterproof tube which carries water from plant roots to leaves. Red blood cells are a ...

All living things have a blueprint provided by the DNA that is stored in every one of their cells. Yet the amount of DNA in ...

Cancer remains one of the leading global causes of mortality, with an estimated increase in cases due to lifestyle, ...

Scientists in Japan have created hybrid plant-animal cells, essentially making animal cells that can gain energy from ...

A new method developed by Penn State biologists allows them to turn stripped-down plant cells into other types of cells, ...

If stem cells were able to multiply uncontrollably, this would lead to uncontrolled growth, as in the case of cancer. WOX5 is an important signaling molecule that regulates stem cells in the meristem.

A leaf usually has a large surface area, so that it can absorb a lot of light. Its top surface is protected from water loss, disease and weather damage by a waxy layer. The upper part of the leaf ...

In fact, under a microscope, you'd really have to know what you're looking at to tell the difference between plant and animal ...

Stem cell-like approach in plants sheds light on specialized cell wall formation New method reprograms isolated plant cells to form other cell types Date: October 31, 2024 Source: Penn State ...
