This practice test has 25 important multiple choice questions from the Chapter - Anatomy Of Flowering Plants in Biology - Class 11th.

Q3. Which of the following is not a feature of spring wood?

Color of the wood is light. Density is less. Cambium is active. Lesser number of xylary elements.

Spring season produces a wood which has large number of xylary elements having vessels with wider cavities.

Q4. In a monocot leaf

bulliform cells are absent from the eqidermis veins from a network mesophyll is well differentiated into palisade and spongy parenchyma mesophyll is not differentiated into palisade and spongy parenchyma

mesophyll is not differentiated into palisade and spongy parenchyma

Q5. A.T.S. of a young dicot root can be distinguished from that of a young dicot stem by the presence of

radial arrangement of xylem and phloem collateral arrangement of xylem and phloem interfascicular cambium intrafascicular cambium

adial arrangement of xylem and phloem

Q9. Stem grows in girth due to

outer cortical epidermis vascular cambium phellogen

Stem increase in girth due to the activity of vascular cambium. In this process, the outer cortical and epidermis layers gets broken. This layer is replaced with new protective cell layer

Q10. Which of the following is true about heartwood?

They are dead but gives mechanical support to stem They are light in color They conduct water and minerals. 1 and 3

Heartwood is dead and have non-conducting elements.

Q12. Which of the following helps in the curling of the leaf surface?

Bulliform cells Xylem tissue Palisade parenchyma Bundle sheath cells

In grasses, adaxial epidermal cells along the veins modify themselves into large, empty, colorless cells. These are called bulliform cells

Q16. After the secondary growth, the oldest layer of secondary phloem in a dicot stem is located

just outside the vascular cambium just inside the vascular cambium just inside the vascular phloem just outside the secondary xylem

just inside the vascular phloem

Q18. Vessels differ from tracheids

in being living in being derived from a single cell in that they consist of vertical row of cells with cross walls dissolved in coducting water and minerals

in that they consist of vertical row of cells with cross walls dissolved
