    Along with these adaptations, we find the most impressive specializations of morphology, physiology and behaviour. For example we can marvel at the high-speed swimming of the marlins, sailfish and warm-blooded tunas, air-breathing in catfish and lung­ fish, parental care in the mouth-brooding cichlids and viviparity in many sharks and toothcarps.

MORPHOLOGY AND PHYSIOLOGY OF THE AXIS IN CUCURBITACEAEI ROLAND HOLROYD (WITH PLATES I-III AND FIVE FIGURES) Introduction From the time of HARTIG, a copious literature has developed on the origin and history of the internal phloem.

The writer investigated the embryology and developmental history of Cucumis. Title: Morphology and Physiology of the Axis in Cucurbitaceae Created Date: Z.

Other members of the Cucurbitaceae with 22 chromosomes include Gymnopetalum, Lagenaria, Momordica, Trichosanthes, and Melothria. None appear to be closely related to watermelon. The study of floral morphology in Cucurbitaceae is very important given the broad agronomic implications of this family and the frequent fertilization and fruit set problems present among their members.

The use of microscopy techniques with different levels of resolution allows us to. Austrobryonia (Cucurbitaceae), a new Australian endemic genus, is the closest living relative to the Eurasian and Mediterranean Bryonia and Ecballium.

Cucurbitaceae are usually hairy climbers with simple or branched, lateral tendrils (very rarely, the tendrils are lost, e.g. in the cucumber tree, Dendrosicyos socotranus), yellow or whitish unisexual flowers, an inferior ovary with parietal placentation and numerous,File Size: KB.

Comparative morphological studies on the vegetative and floral parts of all the melon species belonging to the Cucurbitaceae family in Nigeria is being presented together for the first time. This paper forms part of an ongoing research aimed at providing basic anatomy, cytology, molecular genetics, and histochemistry and palynology data on the Nigerian Cucurbitaceae family.

According to Braun () it is a modified bracteole. Engler considered it is modified stipule. Muller () regarded the upper portion of the tendril as a modified leaf and lower stiff portion as the axis. This view was supported by Hagerup ().

The epicotyl elongates after embryo growth into the axis (the stem) that bears leaves from its tip, which contain the actively dividing cells of the shoot called apical meristem.

Further cell divisions and growth result in the formation of mass of tissue called a leaf primordium. 68 videos Play all Morphology of Flowering Plants Neela Bakore Tutorials Looks aren't everything.

The Cucurbitaceae consist of 98 proposed genera with species, mainly in regions tropical and subtropical. All species are sensitive to frost. Most of the plants in this family are annual vines, but some are woody lianas, thorny shrubs, or trees (Dendrosicyos). Many species have large, yellow or white : Tracheophytes.

A compound leaf having leaflets on each side on an axis or mid-rib. Unipinnate: Having leaflets on each side of an axis, e.g., Cassia. Bipinnate: The central axis produces secondary axis which bears the leaflets, e.g., Acacia.

The secondary axes produce the tertiary axes which bears the leaflets, e.g., Acacia. Pollen morphology of the five Brazilian species of the genus Fevillea (F.

Leaflet Shape as a Function of the Proximal-Distal Axis and Left-Right Asymmetries. With respect to leaf morphology, the compound leaves of tomato present a developmental situation more complex relative to simple leaves.

The rachis of the complex leaf is a developmental axis in itself, similar to the heteroblastic series just described. CHAPTER - 5 MORPHOLOGY OF FLOWERING PLANTS Morphology: The study of various external features of the organism is known as morphology.

In anatomy, the second cervical vertebra (C2) of the spine is named the axis (from Latin axis, "axle") or epistropheus. By the atlanto-axial joint, it forms the pivot upon which the first cervical vertebra (the atlas), which carries the head, rotates. The most distinctive characteristic of this bone is the strong odontoid process known as the dens, which rises perpendicularly from the upper FMA: Cucurbitaceae, the gourd family of flowering plants, belonging to the order Cucurbitales and containing 98 genera and about species of food and ornamental plants.
