Water is a major part of cells, forming between 70 and 95% of the mass of the cell. ... In mammals, the alveoli in the lungs are moist with water, to allow gas exchange, and many plants have moist surfaces in their leaves (the mesophyll cells) for gas exchange. ... A main function is to transport materials around the body to where they are needed. ... Plants also lose water in a process called transpiration, and this helps water uptake by the roots, and has an effect on the temperature of the plant, and helps to ...

Animals differ from plants and fungi when it comes to nutrition. ... Collagen is the most abundant of proteins and is not found in plants or fungi. Animal cells are organized into tissues which are groups of similar cells acting as one functional unit. ... This undergoes the progression of mitotic cell divisions without a cell growth between the divisions known as cleavage. ... The genes that control animal development are similar; they have developmental genes that control the functions of other genes. ...

Some triplets have special functions and direct protein synthesis to start or stop. ... The E. coli replicates the plasmids so that a single cell may contain hundreds of identical copies. ... This plasmid is then put back in the Agrobacterium, which transfers the Bt gene into the cotton plant cell. The bacteria does this by infecting the plant cell causing a tumor to form and while infecting the plant part of the plasmid is transferred into the plant's nucleus. Fig. 5 Bt gene insertion into cotton plant cell Biological implications of genetically engineering cotton for insect resistance T...

Chromosomes are cell structures that carry the genetic material that is copied and passed from generation to generation of cells. ... Mutations can occur in either cell type. ... Most of the multicellular plants and animals we know have cells containing membrane bound structures and are therefore called eukaryotes. ... The majority of plant protein-coding genes contain introns, which must be removed from pre-mRNAs to produce mRNAs for translation into proteins. ...
