Some of the questions and their solutions from NCERT Solutions for Class 11: Anatomy of Flowering Plants, are as follows:
Q. State the location and function of different types of meristem.
Ans. Meristems are specialised regions of active cells division which help in the growth of a plant.
Depending upon their location in a plant, the meristems are divided into three types.
(i) Apical meristem: It is present at the apices of roots and the shoot of a plant. The shoot apical meristem causes the elongation of the stem and formation of new leaves. The root apical meristem helps in root elongation.
(ii) Intercalary meristem: It is the meristem that occurs between the masses of mature tissues. It occurs in grasses and helps in the regeneration of grasses after they have been grazed by herbivores. Since the intercalary meristem and the apical meristem both appear earlier in a plant’s life and contribute to the formation of the primary plant body, so they constitute the primary meristem.
(iii) Lateral meristem: It occurs in the mature tissues of roots and shoots of many plants, particularly those that produce woody axis. As it appears later in a plant’s life, so it is termed as the secondary meristem. For examples: Fascicular cambium, interfascicular cambium, and cork cambium.

Q. Cork cambium forms tissues that form the cork. Do you agree with this statement? Explain.
Ans. Yes, Cork cambium forms the tissues that form the cork. When secondary growth occurs in the dicot stem and root, the epidermal layer gets broken. Cork cambium develops from the cortical region to replace the broken epidermal layer of stem so as to replace the outer epidermal cells and protect the stem and root from infections. Cork cambium cuts off cells toward both sides. The outer cells get differentiated into the cork or phellem, on the other hand the inner cells give rise to the secondary cortex or phelloderm. The cork is impervious to water, hence provides protection to underlying tissues.
Q. Cut a transverse section of young stem of a plant from your school garden and observe it under the microscope. How would you ascertain whether it is a monocot stem or dicot stem? Give reasons.
Ans. The monocot stem is characterized by the presence of a large number of scattered vascular bundles, each surrounded by a sclerenchymatous bundle sheath. Vascular bundles are conjoint and closed. The phloem parenchyma is absent, and water-containing cavities are present within the vascular bundles. Xylem vessels are arranged in Y- shaped manner.
On the other hand, the dicot stem is characterised by the presence of conjoint, collateral, and open vascular bundles. The vascular bundles are arranged in the form of a ring. The ground tissue is differentiated into the cortex, endodermis, pericycle, and pith. Xylem vessels are arranged in rows. Medullary rays are present between the vascular bundles.
