MALE & FEMALE GAMETOPHYTE DEVELOPMENT
MALE GAMETOPHYTE

* 0.015 to 0.05 ml
* It has two walls , outer exine and inner intine
* Exine - thick , scluptured and also called as exospore
* Intine - thin, delicate .also called endospore 
* It consists of reserve food materials
* Up to 13 celled condition - development is inner
*Pollination is also called small polination 
* After liberation - numerous development 
*4 primary androgonial cell - androgonial mother cell
*Anthrozites - antherozoid
FEMALE GAMETOPHYTE
* 1.5 to 5 mm
* It has two walls exine , mesospore and intine
*  Has reserve food materials
* Germination takes place inner sites
* It totally depends on the species
* Germination
* Nucleus - numerous divition - formation of free nucleus
* it has large vacuole - peripheral side 
Wall formation after numerous divition

Gymnosperm - Cycas male & female structures

Image
Introduction Gymnosperms are the plants that doesn't produce flowers. So their reproductive structures are cones. Cycas is one of a plant belongs to the group gymnosperms VEGITATIVE REPRODUCTION vegetative reproductive structures of cycas is called bulbils  or  adventitious buds                        bulbil of cycas *  Develop in the basal part of the stem, in the crevices between persistent leaf base  *  Decurrent base is covered with scale leaves and a few foliage leaves,develop from the centre. * After falling on soil, develop to a new one *  Male plant bearing bulbil develop as male cycas  *   Those from female plant develop as female cycas SEXUAL REPRODUCTION Cycas is a dioecious plant ( male and female on different plants ) MALE CONE *  Microsporangiate strobilus * Develop singly at the apex of stem *  Stem may get arrested for the crown *  Growth ...

PTERIDOPHYTE , SELAGINELLA

Image
Introduction Internal morphology of plant shows the structure and arrangement of cells in the plant body. In this section we are going to have a look to internal morphology of selaginella stem,leaf,root & ligule                                                                                    Selaginella sporophytic plant body   STEM *  Cutinised *  Divided in to 3 regions. Epidermis, cortex, vascular cylinder or stele *   Epidermis - uniseriate - prosenchymatous (  plant tissue consisting of long narrow cells with pointed ends) *  Devoid of stomata  and hairs * Cortex  :- multiseriate - compactly arranged parenchyma cells *  In maturity cortex is differentiated into two *  Outer cortex - thick walled lignified pa...

INTRODUCTION TO PALAEOBOTANY

Image
Introduction The history of plants on Earth is many million years old. During this long period where's the varieties of plants emerged on earth. They disappeared due to climatic changes or due to catastrophic events such as earthquakes landslides volcanoes                    most plants of the geological past were decomposed by bacteria after their death a few plans for their parts got buried deep in the soil without decomposition. These planst and plant parts remained well preserved in the sedimentary rocks of the different ages they are called fosills .                   Paleobotany is the study of  fossil plants NOMENCLATURE OF FOSSILS rules governing the nomenclature of living plants are equally applicable to fossils also. fossilization mainly depends upon the hardness and softness of different tissues, so it is very difficult to find out whole fossil structure of a particular pl...
