plasmolysis
ovules
23. The part of the flower that eventually become seeds are the ____?
transpiration
venus flytrap - sundew trap - pitcher of a ptcher plant - tenri of a pea plant- all of the above

concentration outside roots causes plant to lose h20
24. Which fruit or seed is dispersed by water?
vascular cambria
lose
coconut
pneumatophoves
25. Specialized epidermal cells that increase the surface area for absorption of water are ____?
upper epidermal cells
If there is a higher concentration of salts outside of the root - then water will not move inside the roots against the concentration gradient. the roots will dehydrate and eventually die
