Answer: Vegetative propagation is an a s exual method of plant reproduction that occurs in its leaves, roots and stem.
Answer:
VEGETATIVE PROPAGATIONregeneration of new plant from the vegetative part or organ of the parent plant is called vegetative propagation vegetative propagation is used full to separate the plant in wider region mother plant get favourable condition if then colonized to the reason by vegetative propagation the offspring adapted
1 NATURAL VEGETATIVE PROPAGATION-
BY ROOT -
the interact root of several Woody plants such as guava sisoo grow just below the soil produce advantages but should just below the soil produce but should develop from this bird which give rise to new plant
BY STEM -
stamp is the source of natural vegetative reproduction in several plants modification or found in stem to perform vegetative propagation
a Runners- the weak stem of creep forward on the soil that downwardly from node axillary bud are present in the axils of scale leaves node
b s ucker - rise time in similar to runner but it is underground its main stem grow upward and develop advantages root from underground
c offset- the thick and fleshy runner of hydrophytes plant is called offset
BY LEAVES
Titan plant develop adventirious bud on their leaves this word after separating from Mother plant give rise to new plant
BY BULBILS
they are fleshy but which are produced in the axils of leaves in the auxiliary Bud
ARTIFICIAL VEGETATIVE PROPAGATION-GRAFTING
it is the most common method of vegetative reproduction in this method variety of shame spices can be converted into plant of better variety in the technique of trade off to plant are joined in such portion of one part called stock is joint with another plant is called scion
BUDDING-
it is the superior and modern method of plant propagation in this method but of plant are superior varieties grafted in the stem of plant in variety after making oblique you cut up to the bark of stem after fue with this but join with plant as result formed on the new plant
LAYERING-
the method of inductor root formation the branches while they are still attached to a mother plant is called layering
CUTTING -
any part of plant root stem or leaf which has the power to develop itself into a new plant after separating from the mother plant is called cutting
IMPORTANCE OF PROPAGATION
the plant which have lost their power to produce seeds like Banana grapes Rose in it can be propagated by vegetative means only the plant which produce seed in less number are usually propagated vegetative leaf the change of some chemical x-ray and environmental variation as temperature can be studied easily in plant which vegetative propagation the tissue culture technique of vegetative propagation is used to raise disease free plantPhotosynthesis ceases when leaves wilt, mainly because:.
Photosynthesis ceases when leaves wilt, mainly because stomata close, preventing CO2 from entering the leaf.
What is photosynthesis?Photosynthesis is a series of chemical reactions by which plants can produce simple carbohydrates in presence of light.
Photosynthesis requires carbon dioxide and light to produce glucose and release oxygen.
In plants, the interchange of carbon dioxide and oxygen during photosynthesis occurs in specialized structures called stomata.

Miller urey experiment.The Miller Urey experiment refer to a form of chemical experiment that simulated the conditions present on the early Earth and tested the chemical origin of life using those conditions . The experiment performed at the time supported Alexander Oparin's and J. B. S. Haldane's hypothesis that putative conditions on the primitive Earth is important for chemical reactions to produce more complex organic compounds from simpler inorganic precursors.
The first was the “primordial soup” which was a conclusion that when Earth was young, the oceans were filled with simple chemicals important for life and this assemble into living cells.

When you ice skate, the heat generated by the blade of the skate rubbing against the ice causes some of the ice right under the blade to melt. This water acts like a lubricant under the skate that allows the skate to slide.What causes the ice to melt under the blade?
A) weight
B) friction
C) magnetic energy
D) electromagnetic energy
Answer:
Friction
Explanation:
When an object comes into contact with another object, friction is created, some objects have lower or higher friction when they meet each other, tires and the road for instance. Wheels are designed to lower friction, just as an ice skate is made to glide across the ice.

~Zero~
Answer: Ribosomes play a key role in homeostasis. Without ribosomes, a cell would not make proteins. A cell with no ribosome would simply not function. With no protein reproduction to maintain the cell wall there would be no barrier to keep invasive bodies from damaging the inner workings of the cell, there would be no way to produce the needed proteins for rebuilding and maintaining the cell.

Which of the following best explains why deforestation increases the risk of floods in an area? a. Tree leaves catch and retain rain water. B. Trees block the free flow of water. C. Deforestation increases precipitation. D. Tree roots improve soil water retention. Please select the best answer from the choices provided A B C D.
Deforestation increases the risk of floods in an area tree roots improve soil water retention.
Why does deforestation result in higher flood risk?When deforestation takes place, the top layer of soil can be dislodged – this is also known as soil erosion.
When the top layer of soil is unstable, it is unable to retain any of the water that falls on it, resulting in increased surface run-off, which, in turn, increases the risk of flooding.
Thus, option "D" is correct.
