The epidermis is the outermost cellular layer which covers the whole plant structure, i.e. it covers roots, stem, leaves.
It is composed of a single layer of living cells, although there are exceptions.
Epidermis is usually closely packed, without intercellular spaces or chloroplasts. Instead, the epidermis is like a clear spray coating whose sole purpose is to protect the plant from the elements, while still letting the sun shine in. That's particularly important for a leaf because their main job is to photosynthesize.
Composition of Epidermis:
Epidermal Proper Cells
Specialized cells
Stomatal Guard Cells
Trichomes
Epidermal Proper Cells:
These cells vary in thickness and shape
The outer walls, which are exposed to the atmosphere and usually thickened, and may be covered by a waxy, waterproof cuticle which are made up of cutin. Apart from the normal epidermal cells there are also stomata in the epidermis of leaves and stem.
Wax in the form of granules or rods may be deposited on the surface of cuticle as continuous.
Specialized Epidermal Cells:
In certain species of pteridophytes and gymnosperm, many species of Graminae and certain dicots, fiber-like epidermal cells are formed.
In Graminae and many other monocots ,bubble-like cells are formed called Bulliforms cells, these cells are larger then normal epidermal cells and are thin walled.
Function:
These cells are concerned with opening of rolled leaf as enclosed in bud.
Rolling and unrolling of mature leaves as a result of loss and uptake of water.
Stomatal cells:
A stoma is an opening (pore) which is bounded by two bean shaped cells called guard cells and two to four subsidiary cells that lack chloroplasts.
The guard cells differ from normal epidermal cells in that they have chloroplasts and the cell walls are thickening unevenly; the outer wall is thin and the inner wall (nearest the opening) is thick.
The leaf and stem epidermis is covered with pores called stomata (sing., stoma), part of a stoma complex consisting of a pore surrounded on each side by chloroplast-containing guard cells.
The epidermal cells protect the underlying cells.
The waxy cuticle prevents the loss of moisture from the leaves and stems.
The transparent epidermal cells allow sunlight (for photosynthesis) to pass through to the chloroplasts in the mesophyll tissue.
The stomata of leaves and stems allow gaseous exchange to take place which is necessary for photosynthesis and respiration.
Water vapour may be given off through the stomata during transpiration.
The root-hairs absorb water and dissolved ions from the soil.

Biodiversity and conservation strategies of Nymphalidae Butterflies in the h...researchanimalsciences
Nymphalidae butterflies have a number of subfamilies, including the species
such as Browns, Milkweeds, Heliconians and Beaks. These vary greatly in appearance
ranging from small to large, with mostly in medium size. Some among these
butterflies are powerful fliers (Nawabs and Rajahs) or migrants (Painted lady,
Milkweed butterflies) while Bush browns (
Mycalesis visala, Melanitis leda
and
Elymnias hypermnestra)
and Rings (
Ypthima baldus, Ypthima chenui
and
Ypthima philomela
) are weak fliers. Three study sites i.e., Lankamalai of Kadapa
district, Talakona and Tirumala Hills of Chittoor district of Eastern Ghats of Southern
Andhra Pradesh were chosen.
Captive breeding method has been adopted for
restocking the population.
Nearly 26 Nymphalidae species were identified from
6 sub families. Species diversity
was calculated by using Simpson’s diversity indices
along with the seasonality and population index, richness and evenness of the species
were also discussed.

Francesca Gottschalk - How can education support child empowerment.pptxEduSkills OECD
Francesca Gottschalk from the OECD’s Centre for Educational Research and Innovation presents at the Ask an Expert Webinar: How can education support child empowerment?
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Near Threatened
has relatively translucent wings that are approximately 30-32
millimeters long.
wings are a unique feature for this bat that allow for easy
identification.
body length is 44-48 millimeters with a 41-47 millimeter long
posterior tail.
5. RANGE DESCRIPTION:
In the Philippines, there are records from Jolo (Taylor 1934),
Mindanao (Davao del Norte Province) and Palawan (Heaney et al.
1998).
HABITAT:
There are records of two groups roosting in dead leaves on
small shrubs in lowland forest in the Philippines (Taylor 1934;
Heaney et al. 1998). On Palawan Island, there are records from
secondary lowland forest at 80 m asl (Esselstyn et al. 2004).
MAJOR THREAT:
This species is dependent on primary forest which is being
lost due to logging, plantations, conversion to agriculture and forest
fires.

found in Brunei, Indonesia,Malaysia, the Philippines,
and Thailand.
forearms, 30-31 mm.
7. RANGE DESCRIPTION:
In the Philippines, records are from Luzon Mindanao (Davao
del Norte, Davao del Sur, Davao Oriental, and Zamboanga del Norte
Provinces), Palawan, and Panay (Heaney et al. 1998; Taylor 1934)
and Polillo (Alviola 1999).
HABITAT:
In the Philippines, the species has been found in disturbed
forest and agricultural areas (Sanborn 1952). On Palawan island, it
has been reported from cogon grassland at around 60 m asl
(Esselstyn et al. 2004) and in secondary forest beside a creek at
450 m asl on Mt. Makiling (Laguna, Luzon) (Heaney et al. 1998;
Sedlock 2001).
MAJOR THREAT:
There are no major threats to this species throughout its
range. In the Philippines, the species is locally threatened at higher
elevations in montane forest on ultramafic soils through activities
associated with mining (D. Balete pers. comm. 2006).
8. Common name:
Little long-fingered
bat
Scientific name:
Miniopterus
australis
Family:
Vespertilionidae
Conservation Status:
Least Concern
medium sized for a vesper bat
with large feet and more prominent nostrils than
other European Myotis species
hair is dark grey at the base, with light smoky grey
dorsal-side hair and light grey ventral-side hair.
9. RANGE DESCRIPTION:
It occurs throughout the Philippines except Babuyan/Batanes group
with specimens recorded from Bongao, Bohol, Capiz, Catanduanes, Guimaras,
Leyte, Luzon (Bulacan, Kalinga (Heaney et al. 2004), and Rizal provinces),
Mindanao (Davao del Norte, Davao del Sur, Maguindanao, and Zamboanga del
Norte provinces), Negros, Panay, Polillo, and Siquijor (Heaney et al. 1998)
being found from sea level to about 925 m asl (Heaney et al. 1998;
Esselstyn et al. 2004; Heaney et al. 2004). The species has also been recorded
from Samar (J. C. Gonzales pers. comm. 2006), Cebu (Paguntalan pers. comm.
2006) and on Isarog at 1,450 m asl (Sedlock unpubl. data).
HABITAT:
In the Philippines, the species is often dependent on caves (Heaney et
al. 1998, Esselstyn et al. 2004) where it forages over the canopy in secondary
and primary lowland areas, including agricultural areas (Heaney et al. 1991;
Lepiten 1995; Rickart et al. 1993; Sanborn 1952; Taylor 1934). It has also been
documented in montane forest on Luzon (Heaney et al. 2004).
MAJOR THREAT:
There are no major threats to this species, although it is presumably
locally threatened by disturbance of maternity caves. In the Philippines,
limestone quarrying is destroying roosting habitat and it is also threatened by
disturbance caused by guano mining there, however, individuals reoccupy
caves once the disturbance ceases.
10. Common name:
Schreiber's Long-
fingered bat
Scientific name:
Miniopterus
schreibersi
Family:
Vespertilionidae
Conservation Status:
Near Threatened

average size for a vesper bat.
slightly bigger than the Miniopterus australis.
11. RANGE DESCRIPTION:
Occurs from south-western Europe and north and west Africa
through Anatolia and the Middle East to the Caucasus. In Africa it is known
from records in North Africa (Morocco, Algeria, Tunisia, Libya), and west
Africa (Guinea, Sierra Leone, Liberia, Nigeria, Cameroon). It is patchily
distributed over its range in some huge and vulnerable colonies.
HABITAT:
It forages in a variety of open and semi-open natural and artificial
habitats, including suburban areas. It feeds mainly on moths, and
occasionally on flies. It is a colonial species that roosts mostly in caves and
mines (although it can also be found in man made tunnels, ruins and other
buildings), often in large mixed colonies with other cave-dwelling bat
species.
MAJOR THREAT:
The disturbance and loss of underground habitats and pesticide
use may threaten this species. In the Caucasus, disturbance caused by
tourism in caves is a problem (K. Tsytsulina pers. comm. 2005).
12. Common name:

It is found throughout the Philippines with records from
Bohol, Cebu, Guimaras, Leyte, Lubang, Luzon, Palawan, Mindanao
(Maguindanao, and Zamboanga del Norte provinces), Mindoro,
Negros, Samar, and Tablas (Hollister 1912; Lawrence 1939; Peterson
1981; Taylor 1934; Heaney et al. 1998; Esselstyn et al. 2004) where
it occurs from sea level up to 430 m asl (Heaney et al. 1998;
Esselstyn et al. 2004). It has been recorded between sea level and
1,600 m over its entire range.
HABITAT:
On Palawan it has been recorded in old growth forest
(Esselstyn et al. 2004). It is an aerial insectivore that catches
insects above the forest canopy, in open areas, in disturbed forest
and in some agricultural areas.
MAJOR THREAT:
There are no major threats to this species throughout its
range, however, locally it is affected by disturbance of caves.

Myotis horsfieldii
Family:
Vespertilionidae
Conservation
Status:
Least Concern
forearms, 35-38 mm.
found in China, India, Indonesia, Malaysia,
Myanmar, the Philippines, Thailand, and
Vietnam.
17. RANGE DESCRIPTION:
In the Philippines, it has been recorded from sea level to 800 m asl
(Heaney et al. 1998) although there is a record from 1,450 m asl on mount
Isarog Camarines Sur Province, in the southeastern portion of Luzon Island.
There are records from the Philippine islands of Bohol, Catanduanes,
Luzon (Camarines Sur, Cagayan, Laguna, Pampanga, Quezon, and Rizal
provinces), Mindanao (Lanao del Norte Province, Misamis Occidental),
Negros, and Palawan (Heaney et al. 1998) and Polillo (Gonzales pers.
comm. 2006).
HABITAT:
In the Philippines, it has been recorded near to streams in lowland
forest, disturbed forest and agricultural areas. In the Philippines, it
sometimes roosts in caves and in tunnels and has been reported roosting
beneath a large rock over a stream (Taylor, 1934).
MAJOR THREAT:
There appear to be no major threats to this species as a whole.
