Two direct defenses of plants against predators include thorns and chemical deterrents. Thorns or spines physically deter herbivores from feeding on the plant, while chemical defenses, such as alkaloids or tannins, can be toxic or unpalatable, making the plant less appealing to predators. These adaptations help enhance the plant's survival and reproductive success in the face of herbivory.
Some herbivores have evolved ways to hijack plant defenses to their own benefit, by sequestering these chemicals and using them to protect themselves from predators. Plant defenses against herbivores are generally not complete so plants also tend to evolve some tolerance to herbivory.
Ocean plants can protect themselves from predators through physical defenses like hard shells or spines on their leaves or stems. They can also use chemical defenses by producing toxins or compounds that deter herbivores from feeding on them. Some plants may also have camouflage techniques to blend in with their surroundings and avoid detection by predators.
Spiny burr grass and trample burrs are examples of weeds that catch on socks and poke legs. The grass and the non-woodies in question number among the plants that have self-defenses against predation by competitive and rival predators, be their animal or plant. The defenses range from bristles to hairs and spines.
Sap containing Urushiol, which causes itching and a rash. example poison ivy and plants producing either cardiac or steroidal glycosides. example foxglove
Cacti have their spines that keep animals from resting and eating their fruit
Swimming in schools (their numbers, volume, and patterns, make it hard for predators to pick out individual fishes); and hiding in clefts under sea plants.
no plants can not be predators

Plants have physical defenses such as thorns and trichomes, chemical defenses like toxins and repellents, and also inducible defenses that are activated in response to herbivore attack.
Invasive species are plants and animals that have migrated or be placed in places were they are not native. This is very harmful to the native flora and fauna who have no natural defenses against the invaders.
Plants have evolved various natural defense mechanisms to protect themselves from predators, such as producing toxins, thorns, spines, or hairs that deter herbivores. Additionally, some plants have developed symbiotic relationships with beneficial organisms, like predators or parasitoids, that help defend against herbivores. Overall, plants have a range of strategies to defend themselves against threats in their environment.
Saxifrage is a plant. Plants do not have predators.
