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 ...
Cell structure Description Function Cell type Cell wall Freely permeable layer surrounding cell membrane. The cell wall of plant cells is made from cellulose. This gives them a rigid structure.
A look at the cells of different organisms and a comparison of the structures found in plant and animal cells. All animal cells are surrounded by a membrane which contains the cytoplasm.
"Flowering plants have succeeded in adapting to the most unwelcoming and harshest environments in the world, in part due to the construction of their cell walls. They provide the plants with both ...
Researchers at the University of Bayreuth and Heinrich Heine University Düsseldorf have described a previously unknown mechanism in the perception of light and heat in plants. The results ...
Researchers from Umeå University, Sweden, and Cornell University, U.S., have discovered a widespread mechanism in bacteria that enhances the bacteria's defense against environmental threats.
