This document discusses the adaptations of epiphytes and halophytes to survive in extreme environments. Epiphytes attach themselves to trees without soil and have aerial roots to absorb moisture from air. They have thick cuticles, sunken stomata, and velamen tissue in roots. Halophytes can tolerate saline conditions. They have adaptations like stilt roots, buttress roots, and pneumatophores for gas exchange and anchorage. Their leaves are thick and hairy to reduce water loss. Both epiphytes and halophytes have anatomical and physiological adaptations to conserve water in arid conditions.

Vascular Cambium & Seasonal activity & its Role in Stem & RootFatima Ramay
Vascular Cambium & Seasonal activity & its Role in Stem & Root:
The vascular cambium (pl. cambia or cambiums) is a lateral meristem in the vascular tissue of plants.
The vascular cambium is a cylindrical layer of cambium that runs through the stem of a plant that undergoes secondary growth.
In Dicots:
The vascular cambium is in dicot stems and roots, located between the xylem and the phloem in the stem and root of a vascular plant, and is the source of both the secondary xylem growth (inwards, towards the pith) and the secondary phloem growth (outwards).
In Monocots:
Monocot stems, such as corn, palms and bamboos, do not have a vascular cambium and do not exhibit secondary growth by the production of concentric annual rings. They cannot increase in girth by adding lateral layers of cells as in conifers and woody dicots.
Cambium of some plants remains active for the entire period of their life, i.e., cambial cells divide and resulting cells mature to form xylem and phloem elements.
This type of seasonal activity usually found in the plants present in the tropical regions, and not all plants show cambial activity.
Percentage of ringless trees in the rain forests of;India : 75%Amazon : 43%Malaysia : 15%
In regions with definite seasonal climate; seasonal activity of cambium ceased with onset of unfavorable conditions; In Autumn, it enters the dormant state and lasts for the end of summer; In Spring, cambium again becomes active.
Duration of cambial activity is also affected by day-length, e.g., In Robinia pseudoacacia, cambium is dormant under short-day condition.
The cambium cells formed in circular in cross section from the beginning onwards.
The cambial ring is partially primary (fascicular cambium) and partially secondary (interfascicular cambium).
Periderm originates from the cortical cells (extra stelar in origin).
In Dicot stem, for mechanical support xylem is with comparatively smaller vessels, greater fibers and less parenchyma.
More amount of cork is produces for protection.
Lenticels on periderm are very prominent.
The cambial ring formed is wavy in the beginning and later becomes circular.
The cambium ring is completely secondary in origin.
Periderm originates from the pericycle (intra stelar in origin).
In Dicot root, xylem is with big thin walled vessels with few fibers and more parenchyma.
Less amount of cork is produced as root is underground.
Lenticels on periderm are not very prominent.

xerophyte verus mesophyte
=========================================================
A xerophyte is a types of plant that has adjusted to get by in a domain with minimal fluid water,
for example, a forsake or an ice-or snow-canvassed locale in the Alps or the Arctic.
The morphology and physiology of xerophytes are differently adjusted to moderate water, and
usually likewise to store substantial amounts of water, amid dry periods. Different species might
be adjusted to survive long stretches of parching of their tissues, amid which their metabolic
action may viably close down. Plants with such morphological and physiological adjustments are
xeromorphic.
Xerophytic plants may have comparable shapes, structures, and structures and look
fundamentally the same as, regardless of the possibility that the plants are not firmly related,
through a procedure called concurrent development. For instance, a few types of desert flora
(individuals from the family Cactaceae), which advanced just in the Americas, may seem like
Euphorbias, which are dispersed around the world. A random types of caudiciforms, plants with
swollen bases that are utilized to store water, may likewise show such likenesses.
Xerophytic plants can have less general surface territory than different plants, so diminishing the
range that is presented to the air and lessening water misfortune by vanishing. Xerophytes can
have littler leaves or less branches than different plants. A case of leaf surface decrease are the
spines of a desert flora. A case of compaction and diminishment of spreading are the barrel
desert flora. Different xerophytes may have their leaves compacted at the base, as in a basal
rosette, which might be littler than the plant\'s blossom. This adjustment is displayed by some
Agave and Eriogonum species, which can be discovered developing close Death Valley.
A few xerophytes have minor hairs on their surface to give a wind break and decrease wind
current, along these lines diminishing the rate of dissipation. At the point when a plant surface is
secured with minor hairs, it is called tomentose.
In a still domain, the regions under the leaves/spines where transpiration is occurring structure a
little limited environment that is more soaked than typical with water vapor. In the event that this
is not overwhelmed by wind, the water vapor potential angle is diminished as is transpiration.
Subsequently, in a windier circumstance, this confinement is not held thus the angle stays high,
which helps the loss of water vapor. Spines trap a layer of dampness furthermore moderate air
development over tissues.
===================
Mesophytes are earthbound plants which are adjusted to neither an especially dry nor especially
wet environment. A case of a mesophytic living space would be a country calm glade, which
may contain goldenrod, clover, oxeye daisy, and Rosa multiflora.
Mesophytic plants have unbending, tough, openly expanded stems and stringy, all around create.
“Any characteristic of an organism or its part which enable it to survive in its own particular habitat is called adaptation”. It is also defined as, “Adaptation is the evolutionary process whereby an organism becomes able to survive and reproduce in its habitat or habitats”. Adaptation is nothing but any changes in the structure or function of an organism or in any parts of its that results from natural selection and by which the organism becomes better fitted to survive and multiply in its environment.

2. PLANT ADAPTATIONS
Plants can survive in many extreme environments.
In order to survive in such environments, these plants
need to have adaptations.
Here ,it deals with epiphytic and halophytic
adaptations.
3. EPIPHYTES
These are mainly small shrubs or herbs
attaching themselves to trunks and
Branches, without putting down roots
in soil.
In this way, they can grow high up in
the canopy layer and capture sunlight
to carry out photosynthesis.
They are harmless to the host.
Epiphytes have aerial roots to capture
moisture from the air.
4. MORPHOLOGICAL ADAPTATION
Roots are well developed.
Three types of roots present.
1.absorbing roots (absorbs minerals and nutrients from host)
2.clinging roots(firmly fix to host)
3.aerial roots.(spongy in nature & absorbs atmospheric moisture)
Stems in some epiphytes are succulent and leaves are reduced in
number.
5. ANATOMICAL ADAPTATIONS
Thick cuticle
Sunken stomata
Surface of aerial roots are not cutinized.
Water storage tissues seen in succulent types.
Aerial roots posses greenish, white thin walled massive
tissues called VELAMEN.
Cells of velamen are hygroscopic and absorbs moisture from
air.
Their cell wall posses spiral or reticulate thickening & does
not posses protoplasm.
Distinct exodermis present below velamen
Vascular system well developed.
Cortex is parenchymatous
7. HALOPHYTES
80% of the earth is covered by saline water
Very few plants are able to tolerate saline conditions without
serious damage
Plants that survive in saline environments are termed halophytes
Most halophytes prefer saline conditions but can survive in
freshwater environments
Most halophytes are restricted to saline environments.
EG. Rizophora, Avicennia, Sonneratia.
They posses STILT ROOTS and BUTTRESS ROOTS.
They produce negatively geotropic breathing roots-
PNEMATOPHORES.
Seeds germinate before their dispersal and germinated seeds fall as
seedlings and grow on suitable substratum.
Secrete SALTS & posses water storage tissues.
8. MORPHOLOGICAL ADAPTATION
STILT ROOTS are also called as prop roots
Arise from aerial branches which enter the layers of soil.
Helps efficient anchorage of plants.
STILT ROOTS
ROOT BUTTRESS
9. PNEMATOPHORES OR BREATHING ROOTS are produced
from horizontal roots.
Negatively geotropic and posses air pores or lenticels
Gaseous exchange takes place through these pores.
Anatomically made of arenchyma bering air chambers.
PNEMATOPHORES
10. Leaves are thick leathery and glassy.
Densely covered with branched or unbranched hairs.
Fruits and seeds well adapted for dispersal through air and
water. Light weighted and bears air chambers.
Viviparous germination.
Each seedling consists of club shaped hypocotyle and
downwardly projecting radicle.
13. Physiological Adaptation
High rate of transpiration
Release dissolved salts as exudates.
Produce additional shallow roots for
water absorption.
Osmotic conc. Of cell sap is high; helps in the absorption of
water from saline soil.
