A. Pectin
B. Myrosin, enzyme
C. Latex
D. Alkaloids

Answer 1

Hint: 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.

- Species belonging to Cruciferae are mostly annual, biennial or perennial herbaceous plants.
- 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.

The plants of this family can be cultivated as vegetable crops such as cabbage, Raddish, etc. Seeds of these plants can also be used for extracting oil such as mustard oil.
