B. Myrosin, enzyme
C. Latex
D. Alkaloids

Answer 1

Plants are the multicellular eukaryotic organisms. They are the autotrophs which means that they can make their own food with the help of a process called photosynthesis. Photosynthesis is a process in which plants make their own food with the help of Sunlight, Chlorophyll, Water and Carbon Dioxide.

- The leaves of members of this family are deeply lobed. Flowers of these species are actinomorphic and ebracteate (without subtended bracts).
- The main characteristic of the members of this family is the presence of Myrosin enzyme which is secreted by the secretory cells present in the members of family Cruciferae.
- The function of myrosin is to catalyse the hydrolysis of a class of compounds called glucosinolates.
