Genetic Code

RNA containing the nucleotide adenine, guanine, cytosine and uracil (U). When three continuous nucleotide or amino acid code to signal the beginning or the end of protein synthesis, this set is known as a codon. This set of triplet gives instructions for the production of amino acids. The amino acids are linked together to form proteins.

Cell Division and Protein Synthesis

CHROMOSOMES
Chromosomes are string-like structures located in the cell nucleus of animal and plant. Each chromosome is made of protein and a single molecule of DNA.

Cell Membrane and Transport

The cytoskeleton is a framework of cell membranes that work as a cover for and protect their internal organelles. This function is vital in animal cells, that lack a cell wall. The order membrane cytoskeleton (cellular networks ‘skeleton’ made of protein and is contained within the cytoplasm) and gives shape to the cell. The cytoskeleton microfilaments attached to certain proteins in the cell membrane, especially an integral part.
Passive Transport

Plant Tissues

Like other organisms, plant cells are grouped into various tissues. These networks can be simple, consisting of a single cell type, or complex, which consists of more than one type of cell.
Dermal Tissue
Dermal tissue system consists of epidermis and periderm.

Animal and Plant Cell

The cell is the smallest unit of life, and there are microscopic in nature, meaning that they can not be seen with the naked eye. Cell discovered in 1665 by Robert Hooke and is named for the little guy with the “cell” (rooms) at a monastery.

There are two types of cells, cells of prokaryotic and eukaryotic cells. Prokaryotic cells is independent in nature, such as bacteria and archaea. On the other hand, the cells of all multi-cellular creature is a eukaryotic cell. Both animal cells and plant cells are eukaryotic cells, but they have a different structure.
The main difference between animal cells and plant cells is that plant cells have a cell wall, where animal cells do not have it. The cell walls are composed of cellulose provides rigidity plant cell to produce a fixed shape that is rectangular shape.
