and vacuoles allow plant cells to change size. What Is the Origin of Chloroplasts? Like mitochondria, chloroplasts likely originated from an ancient symbiosis, in this case when a nucleated cell ...

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.

An Iowa State University plant biologist received a $1.8 million federal grant to study a gene that affects both how plants ...

Plants control their water consumption via adjustable pores (stomata), which are formed from pairs of guard cells. They open ...

A team of scientists from Monash University has solved the structure of a protein known as "LYCHOS," which can detect and ...

How do plants breathe through stomata? Key regulators of stomata are plant vacuoles, fluid-filled organelles bound by a single membrane called the tonoplast. Plant vacuoles are fluid-filled ...

"We wanted to look at plants ... cell types. "The higher the number of these motifs downstream of the TSS, the more strongly the gene is expressed," Voichek says. "The motif acts like a rheostat ...
