Answer:

what is plasmolysis

Explanation:

Plasmolysis is the process in which cells lose water in a hypertonic solution.

The reverse process, DEPLASMOLYSIS or Cytolysis, can occur if the cell is in a hypotonic solution resulting in a lower external OSMOTIC PRESSURE and a NET flow of water into the cell. Through observation of plasmolysis and deplasmolysis, it is POSSIBLE to determine the tonicity of the cell's environment as well as the rate solute molecules cross the cellular membrane.

Vegetative propagation => The method of GROWING plants from their vegetative parts like roots,stems or leaves etc is known as vegetative propagation.

Ex:- Rose, Sugarcane, Banana, Strawberry etc. are grown by vegetative propagation method.

• Plants produced by vegetative propagation have flowers and fruits much EARLIER than plants produced by SEEDS.
• It is easy, fast method and can be used for propagation of plants which cannot be produced by seeds.
• The plants produced by vegetative propagation bears similar Characteristics as their parents.

• Since, plants are genetically very similar and almost identical,no NEW VARIATION can be generated.
• Plants can still suffer from various plants diseases.

Explanation:

In DEPLASMOLYSIS, water from the outside ENVIRONMENT rushes into the cell through a process called osmosis, which CREATES turgor pressure. The cytoplasm and plasma membrane push against the cell WALL, thereby helping the PLANT to stand upright again

Explanation:

CARL Linnaeus, in the 18TH CENTURY, established a system of CLASSIFICATION of species by similarity. At the time, the system of classification was SEEN as the plan of organization used by God in his creation. Later, the theory of evolution applied it as groundwork for the idea of common descent.

Transpiration is the process of water movement through a plant and its evaporation from AERIAL parts, such as leaves, STEMS and flowers. Water is necessary for plants but only a small amount of water TAKEN up by the ROOTS is used for growth and metabolism. The REMAINING 97–99.5% is lost by transpiration and guttation.

EXPLANATION:

The root of the tree represents the ANCESTRAL lineage, and the TIPS of the branches represent the DESCENDANTS of that ancestor. As you move from the root to the tips, you are MOVING forward in time. When a lineage splits (speciation), it is represented as branching on a phylogeny.

Answer:

Certain pathogens are tissue and organ specific because the nutrients required for them are PRESENT only in those ORGANS.  

Explanation:

For example when a plasmodium falciparum that is the malarial parasite enters the hum BODY through a mosquito it DIRECTLY invades the red blood corpuscles of the body.

It infects and multiplies in population only in the Red blood corpuscles, after it has reached its complete capacity that is the red blood cells are tightly PACKED with the parasites, then they burst open and display the infection.

Transportation In Plants

Transport in plants – plants are the type of organisms that have an autotrophic mode of nutrition. By taking in carbon DIOXIDE from the air, minerals, and water from the soil, plants make their own food. After that, they release OXYGEN and water vapor. This process is Photosynthesis.



By this process, plants synthesize their food in the leaves. For trees, leaves are considered to be food factories. For the process of photosynthesis, raw materials should be transported to the leaves. For transport in plants, they need a transport system to move food, water, and minerals around because for them no heart, no blood, and since these plants do not have a circulatory system, transportation makes up for it.

Why is Transportation An Essential Process?

To circulate water, essential nutrients, excretory products and gases within the plants for various purposes, transportation in plants is NECESSARY. In vascular tissues, this transportation in plant takes place. By a suction force, water and minerals are transported to various parts of the plant.

Vascular tissues are normally conducting tissues. Formation of these tissues can be done by xylem and phloem of a plant. Without the use of pump how water moves up the plant against gravity in tubes made of dead xylem cells can be explained by only transportation process.

The Process of Transportation

In plants, there are pipe-like vessels through which water and minerals can enter the plants. These vessels are made up of elongated cells and thick walls. A group of cells forms a tissue which performs a specialized function within the organisms. These are conducting tissues. These conducting tissues are divided into two types which are xylem and phloem.

Xylem: It is a vascular tissue that spreads from the top to bottom of the plant. For the transport of water molecules, it helps a lot. It also plays a vital role in case of dissolved substances from the root hairs to aerial parts of the plant. It transfers water in one direction. Commonly, xylem OCCUPIES the central part of the vascular bundle. It mainly includes different types of cells such as tracheid, vessels, and xylem parenchyma and xylem fibres.

Phloem: It is also a vascular tissue. In a plant where the necessity of food molecules is there, by the use of phloem transportation process will take place. Some elements are there in the phloem such as sieve elements, phloem parenchyma, fibres and companion cells.

The transportation process in this tissue is bidirectional. In association with xylem, it forms vascular BUNDLES. The edges of vascular bundles are occupied by phloem.

Explanation:

neurofibromatosis has a variable phenotypic expression that includes dermatologic MANIFESTATIONS. Some patients may have a primarily cutaneous expression, while others may have life-threatening or SEVERELY disfiguring complications.

Neurofibromatosis is an autosomal dominant disorder that AFFECTS the bone, nervous system, SOFT tissue, and skin. At least 8 different clinical phenotypes of neurofibromatosis have been identified, and they are linked to at least two genetic disorders. Clinical manifestations increase over time. Neurologic PROBLEMS and malignancy development may supervene.

HEYAA !!! HERE'S FULL EXPERIMENT---->>>

AIM ...

=========

to prepare a temporary mount of leaf peel to show its STOMATA ......

Requirements ...

================

Leaf of a plant like lily, Bryophyllum , or tradenscantia, forceps, waych glass, slide, coverslip , brush, needles, safranin, glycerine, and microscope .

Principal Involved ...

===================

Stomata are minute appertures ( openings ) present on the surface of the leaf . they are generally more on the lower EPEDERMIS . Each stomata is surrounted by two bean-shaped cells called “gaurd cells” . Theae cells have differential thickenings, i.e. THICKER inner wall facing the stoma and thinner outer wall . The turgidity of gaurd cells controls the opening and closing of stomata . Stomata heps in exchange of gases and water vapours between the atmosphere land leaf .

Procedure ...

===============

1 ) Pell off the leaf from its under surface and put the peel in a watch glass containing water .

2 ) Add a few drops of Safranin stain into the watch glass to stain the peel .

3 ) After staining put the peel on the cleaning slide and cut it in a RECTANGULAR or square shape .

4 ) With the help of a filter paper, remove the excess of stain and water .

5 ) Put a drop of glycerine on the slide over the peel, gently put the coverslip to avoid the entry of air bubbles and observe under the microscope .

Observations ...

=================

1 ) Epidermis consists of a single layer of cells which are irregular in outline and without intracellular spaces .

2 ) Minute appertures ( openings ) are seen which are imbedded in epidermal cells .

Result ...

==========

The minute apperture seen in the mount are stomata . Each stomata is surrounded by two bean-shaped cells called gaurd cells .

Precautions ...

================

1 ) The epidermal peel should be taken from a freshly plucked leaf .

2 ) Always hold the slide by its edges to avoid making the slide dirty .

3 ) Always use a brush to transfer the peel from petri dish to the slide .

4 ) The peel should be cut to a PROPER size and its curling must be avoided .

5 ) The peel should be mounted in the centre of the slide .

6 ) The peel should not be allowed to dry .

7 ) Always keep the coverslip gently to avoid the entry of air bubbles .

8 ) Oozing of glycerine should not be there .
