Answer

1. The vascular and dermal tissues

2. Protein capsid

Explanation

Dermal tissue present in plants offer the first defense mechanism against physical damage which could be caused by insects and infections.The dermal tissue covers the outside parts of a plant except in woody shrubs and tree which are protected by the bark. Vascular tissues in plants are responsible for the transportation of water and nutrients that are vital in cell repair and growth.Through vascular tissues, the plant obtains nutrients important for the restoration of the damaged cells.

A capsid is the protein shell of a virus.It is composed of protomers which are subunits.Some viruses are enveloped by a capsid coated with a lipid membrane called the viral envelop.The main function of a capsid is to protect the genetic material of a virus while interacting with the host environment.
