Many of the viruses that infect archaeal cells primarily carry out a lysogenic infection.Even if they do enter a productive infectious cycle, they can release new virions without killing the host cell.What might be the evolutionary advantages of these lifestyle features?
Guard Cells
Specialized cells located within the epidermis of leaves, stems, and various organs responsible for controlling gas exchange and limiting water loss through the opening and closing of stomata.
Stoma
Pores found on the leaf and stem surfaces that facilitate gas exchange between the plant's internal tissues and the atmosphere.
Companion Cells
Specialized cells in the phloem of plants that support the function of sieve tube elements in transporting sugars.
Cuticle Cells
The outermost layer of cells in plants and some animals that provides protection and reduces water loss.
