Identify the plant grow from the data given below:
habitat tree
xylem vessels present
absence of companion cell in phloem
no fruits

While analysing the anatomy of a given slide,phloem,cambium and xylem are present . Identify the material.

Read the following statements carefully and select the appropriate option given below. (i) It is possible to store pollen grains of a large number of species for years in liquid nitrogen (-196^(@)) . (ii) Cells of the nucellus have abundant reserve food materials. (iii) In a normal flower which opens and exposes the anthers and the stigma, complete autogamy is common. (iv) If both male and female flowers are present on the same plant, it prevents both autogamy and geitonogamy. (v) Cultivation of hybrids has tremendously increased productivity.

In the anatomy lab. Eugin observed the following features in the T.S of a plant part. a) Radial and polyarch xylem bundles b) Parenchymatous (homogenous) cortex c) Large pith d) Epidermis with unicellular hairs e) Pericycle f) Endodermis with casparian strips. i) Identify the plant part. ii) Re-arrange the given regions from the periph-ery to the center in their correct sequence. iii) Give an account of casparian strips.
