Protein structure is the three-dimensional arrangement of atoms in a protein molecule. Proteins are polymers — specifically polypeptides — formed from sequences of amino acids, the monomers of the polymer. A single amino acid monomer may also be called a residue (chemistry) indicating a repeating unit of a polymer. Proteins form by amino acids undergoing condensation reactions, in which the amino acids lose one water molecule per reaction in order to attach to one another with a peptide bond. By convention, a chain under 30 amino acids is often identified as a peptide, rather than a protein.[1] To be able to perform their biological function, proteins fold into one or more specific spatial conformations driven by a number of non-covalent interactions such as hydrogen bonding, ionic interactions, Van der Waals forces, and hydrophobic packing. To understand the functions of proteins at a molecular level, it is often necessary to determine their three-dimensional structure. This is the topic of the scientific field of structural biology, which employs techniques such as X-ray crystallography, NMR spectroscopy, and dual polarisation interferometry to determine the structure of proteins.
Protein structures range in size from tens to several thousand amino acids.[2] By physical size, proteins are classified as nanoparticles, between 1–100 nm. Very large aggregates can be formed from protein subunits. For example, many thousands of actin molecules assemble into a microfilament.
A protein may undergo reversible structural changes in performing its biological function. The alternative structures of the same protein are referred to as different conformational isomers, or simply, conformations, and transitions between them are called conformational changes.
All you would have to do is sum them up cause their going the same direction.
The BEST example of technological design is researching a disease resistant corn hybrid.
Answer:
With respect to the cell wall of fungi and plants, it is correct to state that both cell walls provide structural support but fungi is made of polysaccharides and chitin and plants are made of cellulose.
Explanation:
The cell wall is the most external structure of the cells of fungi and plants, giving them form and protection, at the same time that it allows the growth and the function of relation between cells and of these with respect to its environment.
the main difference between the cell wall of fungi and plants is its composition, being in the first ones chitin and glucosamine. In plants, the main component of the cell wall is cellulose.

1. yes it is possible because some plants do not have chloroplasts like Prokaryotes. Not all plants need chloroplasts to survive
