What is the name of the toxin that tobacco plants use to poison predators?

What benefit do Douglas fir trees get from allowing fungi to grow on them?
When they colonize the roots of a tree, fungal networks act as a sort of highway, allowing water, nutrients and even the compounds that send defence signals against insect attacks to flow back and forth among the trees.Oct 22, 2020
How did plant growth differ between sibling and unrelated plants?

Is Rafflesia a parasitic plant?
This delightful organism is actually an obligate parasite and cannot photosynthesize on its own. In fact, 100% of its unpleasantness is fueled with nutrients it steals from the roots of neighboring Tetrastigma vines! Rafflesia makes parasitism pay off in a big smelly way.

Do bugs eat tobacco?
The insects that attack the seedling tobacco or the growing crop include hornworms, flea beetles, aphids, cut- worms, green June beetle larvae, to- bacco budworms, and wireworms. Others, less widely distributed, are webworms, thrips, grasshoppers, mole crickets, vegetable weevils, midge lar- vae, slugs, and suckflies.
How do plants acquire resources for growth?
Just as humans digest food for energy, plants use a number of absorption techniques to get the nutrients and moisture necessary for vigorous growth. As roots dive into the soil, they encounter air, water and nutrient reserves. In contrast, photosynthesizing leaves discover sunlight and air as they rise into the sky.
Do plants have eyes?
Although they may not have eyes, ears, or other physiological features like humans, they find food, nurture their young, communicate with their friends, recognize kin, and even wage underground territorial wars. Plants are among the world’s oldest and most successful organisms.
Do plants breathe out oxygen?
Plants. They are meticulously counted and classified, yet we do not know all their secrets. They stand with attention in open fields, with their leaves saluting the sun, harvesting its energy into its micro factories. They inhale the carbon dioxide we exhale, and they breathe out the oxygen we breathe – a mutualistic relationship.
Do plants have kin?
Like a herd of elephants, plants appear to recognize their kin and are more protective of relatives as compared to non-related members of the same species. An experiment conducted in a Douglas fir forest shows that plants not only share resources, they are more likely to direct them toward their offspring.
Do invasive species have their own social rules?
It appears that the plant world might have its own set of social rules. Invasive species ignore these rules, which make them the bullies of the plant world. They engage in a kind of turf war with other plants that is rare in the “live and let live” spirit of cooperation exhibited by most plants.

Do fungi need carbon?
The plants provide the fungi with carbon-based sugar, and the fungal network returns the favor, providing the trees with nutrients. Many plant species are dependent on fungi for their survival, and the Douglas-fir is no exception. In turn, the underground fungi are equally dependent on the trees' carbon.
Do plants need light?
But plants don't just need light to thrive -- they also need nutrients, food that lies in a hidden world that's just below our feet. As much as 80% of a plant's total mass lives below the ground, in a secret world scientists once called the "black box.".
Do plants eat living things?
All plants are not necessarily eating living organisms, but they're having elaborate behaviors above ground and below ground, but they're slower than the snapping of the flytrap, or they are happening in the soil so we can't see them.
