Parts Of Plants MCQs for NEET

  Plants are biotic factors of the ecosystem. They are photosynthetic, multicellular, eukaryotic in nature and are grouped distinctly into Kingdom Plantae. Contrary to the animals, plants possess a well-defined cell and specialized structures that are chiefly linked with cellular functionalities. These are the only living species who can manufacture/synthesize their own food. They are able to do so because of the presence of specialized structures in the cells of plants. Typically plant parts can be classified as the root system and the shoot system. 1. Which of the following factors promotes the opening of the stomatal aperture? (a) A decrease in guard cell turgidity (b) When the outer walls of the guard cells contracts (c) Radial orientation of the cellulose microfibrils in the cell wall of the guard cells (d) The longitudinal orientation of the cellulose microfibrils in the cell wall of guard cells Answer: (c) 2. Which of the following is made of dead cells? (a) Phloem (b) Phell...
