1. In grasses, certain adaxial epidermal cells along the veins modify themselves into large, empty, colorless cells. These cells are called:- 
(1) Bulliform cells 
(2) Starch sheath cells 
(3) Companion cells 
(4) Complimentary cells 

2. By the activity of the cambium ring, the cells cut off toward the pith, mature into 
(1) Secondary phloem 
(2) Primary xylem 
(3) Secondary xylem 
(4) Primary phloem 

3. In certain regions, the phellogen cuts off closely arranged parenchymatous cells on the outer side instead of cork cells. These are called:- 
(1) Phellem 
(2) Periderm 
(3) Bark 
(4) Complimentary cells 

4. In the dicot root, the vascular cambium is. 
(1) Primary in origin 
(2) Completely secondary in origin 
(3) Both primary and secondary in origin 
(4) Neither primary nor secondary in origin 

5. The innermost layer of the cortex of the dicot root is characterized by the presence of suberin thickening. This suberin thickening occurs on 
(1) Radial walls 
(2) Transverse wall 
(3) Tangential wall 
(4) Both 1 & 3 

6. Regarding stele which of the following statement is correct? 
(1) All the tissues lie inner to pericycle 
(2) All the tissues lie inner to endodermis
(3) All the tissues lie inner to the hypodermis 
(4) All the tissues lie inner to the epidermis 

7. After secondary growth what is the actual future of primary xylem? 
(1) Converts into secondary xylem 
(2) Remains more or less intact in or around the center 
(3) Converts into secondary phloem 
(4) Gets crushed 
8. Regarding wood find out the wrong statement:- 
(1) Vessels of springwood have wider cavities 
(2) Vessels of autumn wood have wider cavities 
(3) Springwood is lighter in color 
(4) Autumn wood has a higher density

9. Select the wrong statement about heartwood : 
(1) It is made up of dead elements 
(2) It does not conduct water 
(3) It gives mechanical support to the stem 
(4) It is involved in the conduction of water and minerals from the root to the leaf 
10. In the dicot stem, pericycle is present on the inner side of the endodermis and above the phloem in the form of semilunar patches, it is made of: 
(1) Parenchyma 
(2) Collenchyma 
(3) Sclerenchyma 
(4) Prosenchyma 
11. In leaves, the ground tissue constitutes of thin-walled parenchymatous chloroplast containing cells and is called ______ 
(1) Mesophyll 
(2) Epidermis 
(3) Stomatal apparatus 
(4) Bundle sheath extension
