Life without bees There are plenty of food sources that don't need bees to pollinate. If the bees became extinct, the plants that depend on bees for pollination will die.

- Increased Toxicity Most plants produce substances that are toxic to humans. Most of the plants that humans consume produce toxins at levels low enough that they do not produce any adverse health effects.nother example comes from a study showing that a strain of genetically modified soybean produced lower levels of phytoestrogen compounds, believed to protect against heart disease and cancer, than traditional soybeans (Bakshi, 2003).

Loss of Bees Can Affect Plantsâ Ability to Reproduce, Study Finds But the larkspur needs pollen from its own species to reproduce and suffered for the bumblebees’ wayward ways. Because of the unfaithful bees, the researchers reported Monday in Proceedings of the National Academy of Sciences, plants produced about 30 percent less seed. The finding, they report, shows a surprising effect from a loss of biodiversity that could have implications for a variety of ecosystems. Loading...

- Primarily because after the chemical is produced, it is locked away. In other words, the poisonous chemicals are stored in the vacuole in the cells. The vacuole is a large water-filled sac teeming with a variety of materials including poisonous chemicals and other waste products.As long as the chemicals are tucked away in the vacuole the remainder of the cell is safe.IV.II. Allelopathy  plant vs. plant Plants are also poisonous to one another. Allelopathy is essentially chemical warfare between plants.

- It's a matter of ecology. In many cases, plants from other parts of the world are welcomed, manageable additions to our gardens. However, in some situations these non-native species cause serious ecological disturbances.hey are most threatening in ecosystems such as wetlands, sand dunes, fire prone areas, and serpentine barrens where rare native plants are found. Invasive plant species thrive where the continuity of a natural ecosystem is breached and are abundant on disturbed sites like construction areas and road cuts.

Phloem Because phloem tubes sit on the outside of the xylem in most plants, a tree or other plant can be effectively killed by stripping away the bark in a ring on the trunk or stem. With the phloem destroyed, nutrients cannot reach the roots, and the tree/plant will die.uring the plant's growth period, usually during the spring, storage organs such as the roots are sugar sources, and the plant's many growing areas are sugar sinks. The movement in phloem is multidirectional, whereas, in xylem cells, it is unidirectional (upward).
