How do plants defend themselves against predators?

To keep small predators at bay, many plants have a mat of fine hairs on the surface of their leaves. To deter larger animals some plants have sharp spines or thorns, while others have leaves that sting or are bitter to taste.

How do herbivores deal with plant defenses?

Herbivore use of plant chemicals

Plant chemical defenses can be used by herbivores, by storing eaten plant chemicals, and using them in defense against predators. To be effective defensive agents, the sequestered chemicals cannot be metabolized into inactive products.

What are some defense mechanisms used by plants?

If thorns, spines, prickles, and trichomes are the spear brigade, idioblasts are the landmines. Specialized cells that contain a variety of defensive compounds, from razor-sharp crystals to pain-inducing chemicals, idioblasts detonate when the first line of defense has been breached.

How plants have evolved Defence mechanism against their predators give two examples?

ii Plants may produce/store chemicals such as nicotine strychnine etc. for defence which inhibit digestion/disrupts reproduction/kill the predator//Calotropis produces. highly poisonous cardiac glycosides//plants may produce chemicals such as nicotine/ caffeine/ quinine/ strychnine/ opium are produced as defence.

How do plants fight off diseases?

Plants have an innate immunity system to defend themselves against pathogens. With the primary immune system, plants recognize microbe-associated molecular patterns (MAMPs) of potential pathogens through pattern recognition receptors (PRRs) that mediate a basal defense response.

How do plants protect themselves from weather?

Plants may hold onto dead leaves for insulation, or use deep snow like a blanket to protect against the cold. Some evergreens also have a special valve in their cells. This valve automatically seals off individual frozen cells to prevent a chain reaction of freezing.

How do plants defend themselves chemically?

Many plants have an inbuilt defence system that, when activated, releases hydrogen cyanide to ward off insects and fungi. It is directed at the part of the plant under attack. This is what makes bitter almonds, apricots, and apple pips toxic when crushed.

How does herbivory affect plant growth?

Herbivory can affect the growth form of plants by terminating shoot growth and initiating branching and by affecting shoot-to-root ratios. Changes in survival, productivity, and growth of individual plant species affect vegetation structure and community dynamics.

How are plant defenses mechanisms exploited by humans?

It is also exploited by humans in medicinal plant use and pharmaceutical development. ... Because producing defenses requires materials (such as carbon and nitrogen) and energy that presumably could be used for growth or reproduction, many believe that defense may be costly for plants.

What characteristics to plant leaves and stems have to protect themselves against parasites?

Trichomes (“leaf hairs”) are specialized epidermal cells found on aerial plant parts that may provide both physical and chemical protection against insect pests.

How do plants respond to high salt stress?

Also, high concentration of salinity causes reduction in leaf fresh and dry weights, with low humidity it causes reduction in shoot and root growth on plants. With affecting stomata, salt stress stops permanence of stomatal reactions. Formation of root nodules, plant sprouts and leaves are affected from salt stress.

Do plants have antibodies?

Although plants do not naturally make antibodies, the plant-derived antibodies (plantibodies) have been shown to function in the same way as mammalian antibodies.
