In comparison with unvegetated soils, the presence of plants markedly affects the structure of soil microbial communities. Plant roots affect the physical, as well as chemical environment through the ...

Heterogeneity in the polysaccharide constituents of plant cell walls has been recognized since the earliest chemical analyses of isolated wall preparations. Clear and dramatic differences in average ...

Do existing plants represent all theoretically possible combinations of structure and function for growth, survival and reproduction? To answer this question an international team from 14 countries ...

A recent study investigating the molecular structure and function of an essential plant hormone could profoundly change our understanding of a key cell process, and might ultimately lead to the ...

A eukaryote is any cell or organism that possesses a clearly defined nucleus. Eukaryotic cells form the foundation of complex, multicellular life, including apple trees, mushrooms, fish and humans.

Plants with more complex water transport structures are more resistant to drought conditions, making them more likely to survive and pass this characteristic on to their offspring. That’s the ...

Show an alien how much you know about plant life on Earth. Answer a quiz on plant structure and function. Identify labels for plant parts. Match each plant part with its function. This learning object ...

• Background Higher plants are, like animals, organisms in which successful completion of the cell cycle requires the breakdown and reformation of the nuclear envelope in a highly controlled manner.

Ammonium toxicity resulted in morphological modifications of tomato leaf chloroplasts. The chloroplasts, which are normally flattened around the protoplast periphery, became ellipsoidally rounded and ...
