The functions of two physical structures of plants are described below: (2 points)Structure 1: Holds the leaves of the plant toward the light.Structure 2: Helps reduce water loss.What statement is true about the functions? aStructure 1 is the stamen and Structure 2 is the pistil. bStructure 1 is the stem and Structure is the waxy covering. cStructure 1 is the pistil and Structure 2 is the fuzzy hair. dStructure 1 is the waxy covering and Structure 2 is the stamen.

Functions of Plant Cells

In biology, it is often said that "structure relates to function." This means that the way something looks, is constructed, or shaped, gives you a hint about the function (job) of that object.The function of a cell wall is to provide rigid structure and support to the cell. Find the cell wall in the image below:Simple diagram of plant cell by Domdomegg (CC BY 4.0)Considering the function of the cell wall, what would you expect its structure to be like?Elimination ToolSelect one answerAThin, fragile, with large holes.BSoft and flexible.CHard and tough.DFull of green pigment for capturing sunlight.

How does the structure of dermal tissue allow it to carry out its function?A.Its cells are small and tightly packed in order to form a protective covering for the plant.B.Its cells have thick, fibrous cell walls that provide strength and flexibility to the plant.C.Its cells are narrow, hollow tubes with pits that allow water to be transported throughout the plant.D.Its cells have large vacuoles that can expand to store sugars and water for the plant.SUBMITarrow_backPREVIOUS
