There are several possibilities.
One that comes to mind is that these strong odors may have been developed as secondary compounds which functions as a defensive mechanism against predators.

Oxygen in plants is for absorption of nutrients across the cell walls and roots.Oxygen is also used to produce glucose and fructose, which are the main products of photosynthesis, excess Oxygen is released via transpiration.Oxygen therapy is a treatment that provides you with extra oxygen, a gas that your body needs to work well. Normally, your lungs absorb oxygen from the air.Oxygen is needed by plants for energy through night time hours.
Can only transport water short distances
A Specialized tissue is a connective tissue include a number of tissue with specialized cell and unique ground substance . some the tissues are strong while some are flexible and in fluid example blood , bone , cartilage , lymph etc. I HOPE THIS WILL HELP YOU .
First of all, your hypothesis ... plants don't have feelings ... may be false. The only thing you can say for sure is that if plants have feelings, they don't communicate them to us in a way that we can understand. Next, if in fact they don't have any, then the reason is most likely the same as the reason that pigs don't swim, people don't fly, and rocks don't talk.
All plants produce Seeds for ONE very important Reason.
One major difference is that fungal cells have cell walls that contain chitin, unlike the cell walls of plants, which contain cellulose. Fungus doesn't need sunlight to grow unlike plants so fungus doesn't have chloroplast which is the main reason why most plants have leaves, which are essentially solar panels which produce glucose.
Gymnosperms do not produce fruits because their seeds are not enclosed within an ovary. Instead, they have naked seeds that are exposed on the surface of specialized structures such as cones or scales. This lack of an ovary is the main reason why gymnosperms do not have true fruits.
Bean plants can grow a lot in dark places but they don't produce. The reason why beans grow so long in the dark is because they try to find light. And they turn blonde.
the reason why plants dont have skeleton because plants have stems.

The adaptation of specialized water conducting tissue has helped land plants meet the challenges of life on land for a few reasons. The most important reason is that the cell walls were stronger and could support themselves.
Number 1 reason: People keep chopping trees/plants down Number 2 reason: Oil
There really aren't impacts on the environment, unless you were to spray the Dry powder outdoors for no reason.
Plants need sunlight to produce sugars which they use for their nutrition. Then herbivore animals eat the plant to get energy and after that the carnivore animals eat the herbivore animals for the same reason. The energy of sunlight has traveled through plants, herbivores and carnivores, for example to humans who eat other animals.
Spiders are not killing your plants. If anything, they are good for your plants, since they eat insects that eat plants.
The root hairs are structurally specialized to perform absorption of water. For this reason the cell wall remains very thin and permeable.
