Consider the following passage. Plant leaves are organs that are composed of multiple cell types, including palisade cells and
guard cells. Palisade cells contain many chloroplasts and are the main sites of photosynthesis in
a leaf. Guard cells are specialized epidermal cells that can change shape in order to control gas
exchange between the leaf and its surroundings.
Which claim is best supported by evidence provided in the passage?
Choose 1
A leaf is primarily made up of one cell type, which allows it to carry out the process of
photosynthesis.
B
Palisade and guard cells each have the capacity to carry out all the functions of the leaf.
independently.
The various cell types found in a leaf have unique, specialized functions.

answer; bodies of water store heat during the day and release it at

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
