Name the instrument pictured below.

During photosynthesis, _______ enters the leaf and _______ exits the leaf.

The ability of water to move in narrow passageways against the flow of gravity is termed __________ action.

The structure of water includes ______ oxygen atom(s) and _____ hydrogen atom(s).

Water is a _________ compound, meaning it has portions that are partially positively and negatively charged.

Within a single water molecule, the atom with the greatest "pull" for electrons that develops a partially negative charge is __________.

Within a single water molecule, hydrogen possesses a partial ________ charge.

The attraction between the atoms in a single molecule of water is a _________ bond.

The attraction between DIFFERENT molecules of water is termed a __________ bond.

While a single hydrogen bond is fairly _______, the collective sum of many hydrogen bonds is _______.

Water forms droplets due to the ____________ forces by which water is attracted to other water molecules.

Water will move slowly down a windowpane, sticking to a glass surface composed of polar material, due to ________ forces.

The openings on the bottom surface of a leaf through which gas exchange occurs are called ___________.

Each pore on the bottom of a leaf is surrounded by _____ (#) __________ (name), which control the opening and closing of the pore.

The vessels through which water moves through a plant are termed __________________.

Xylem vessels are composed of ________ cells, in which the cell wall, cell membrane, and organelles have disappeared at maturity.

An increase in temperature will lead to a(n) _______ in the rate of transpiration due to more __________ of water from stomata.

An increase in ___________ will lead to a decrease in the rate of transpiration due to water saturation of the air immediately surrounding the leaf, thus decreasing pressure for water to exit the leaf into the surrounding environment.

For most plants, the rate of transpiration _________ during the day and _______ at night due to the opening and closing of stomata by guard cells.

The name of the helical polymer which provides structural rigidity to xylem vessels is __________.

Water movement through plants occurs in one direction, from _________ to _________.

Entry of water into roots occurs through due to a relatively higher concentration of water in _______ compared to ______.
