A plant cell wall is arranged in layers and contains cellulose microfibrils, hemicellulose, pectin, lignin, and soluble protein. These components are organized into three major layers: the primary ...

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 ...

Adam: My name is Adam, and I work for a fruit and vegetable business. Plant cells have a rigid cell structure. They are made up of a cell wall, cell membrane, cytoplasm, vacuole, nucleus ...

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.

Most research on plant stem cells focuses on the tips of roots and shoots, where growth occurs in height. But biologist ...

So, any green you see on a plant — the leaf, the stem, in the peel of an unripe banana — all comes from the chloroplasts in ...

Research on organic solar cells has been conducted for a long time. Recent advancements in understanding their molecular ...

Major topics include plant responses to light, carbon dioxide levels, mineral nutrition and abiotic and biotic stresses such as drought and pests. Emphasis is on mechanisms by which changes in the ...

A team has clarified how in plants the boric acid channels, the conduits for the necessary element boron, are transported to the plasma membrane.

Dysfunctions of the tiny cell processes (primary cilia) of the pancreatic beta cells could be a cause of type 2 diabetes.

Various types of fuel cells exist, but the one automakers are primarily focusing on for fuel cell cars is one that relies on a proton-exchange membrane, or PEM. In the generic PEM fuel cell ...

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 ...
