When guard cells lose potassium ions, water diffuses out of the cells by osmosis. As water leaves the cells, they become flaccid and less bowed, which closes the stomata between them.
Habitat its really important for something to stay alive
Answer:
In roots, the vascular tissues, i.e., xylem and phloem, are found in the central vascular cylinder, while in stems these tissues are dispersed throughout the stem, generally arranged as a ring towards the outside of the stem (epidermis)
Explanation:
Vascular plants have two different transport tissues: xylem and phloem. The xylem transports water from roots to stems and leaves, while the phloem transports food (i.e. dissolved sugars) from the leaves to all parts of the plant. In roots, vascular tissues form a central core in order to withstand stretching forces. Moreover, in stems, vascular tissues are dispersed (generally concentrated towards the epidermis), in an arrangement that enables them to resist compression and bending forces.
Explanation:
A high level of biodiversity leads to a better sustainability of the natural environment.
- Biodiversity is the variation of plant and animal species in an ecosystem.
- The natural environment deals with the living and non-living part of the ecosystem.
- A wide range of diversity in the ecosystem brings in broader level of interaction among the different constituents of the environment.
- Biodiversity ensures there is no over dependence on a particular resource in the environment. Organisms have access to a pool of resources.
- In adverse times, it ensures that quite a number of organisms are still able to live and thrive well.

The correct answer is 4
Explanation:
The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.
