MCQs on Plant Anatomy

Plant anatomy refers to the study of the internal structures of the plant. Plants are made up of a variety of cells that are organized into tissues. Tissues are further organized into organs that perform specific functions to carry out the life processes of the plants.

Plants comprise two organ system – the root system and the shoot system.. The roots absorb water and minerals from the soil which is transported to different organs of the plant through the stem. The leaves perform photosynthesis whereas the flowers are the reproductive organs of a plant.
