Plant Tissue Characteristics and Functions

What is a key characteristic of meristematic tissues in plants?

• They are composed of dead cells.

• They have lost the ability to divide.

• They consist of cells that can continuously divide.

• They primarily provide structural support without growth.

Which type of meristematic tissue is responsible for increasing the thickness of a plant's stem or root?

• Apical meristem

• Intercalary meristem

• Lateral meristem

• Permanent meristem

How are permanent tissues formed in plants?

• They are formed directly from undifferentiated cells.

• They develop from meristematic tissues that have lost their ability to divide.

• They are created through the fusion of different cell types.

• They are primarily responsible for active cell division.

What is the primary function of Aerenchyma in plants?

• Photosynthesis

• Storage of starch

• Buoyancy

• Mechanical support

Which of the following accurately describes collenchyma cells?

• They are dead cells with lignin deposits.

• They are living cells with large intercellular spaces.

• They are living cells with no intercellular gaps and thickened corners due to pectin and cellulose.

• They are unspecialized cells found throughout the plant body.

What is a key characteristic of sclerenchyma cells?

• They are living cells that store starch.

• They are elongated, dead cells with lignin deposits in their cell walls.

• They provide flexibility to plant parts like leaf petioles.

• They have large air voids for buoyancy.

Which statement accurately describes the primary function and direction of transport for xylem and phloem tissues in plants?

• Xylem transports food bidirectionally, while phloem transports water unidirectionally.

• Xylem transports water unidirectionally, while phloem transports food bidirectionally.

• Xylem transports food unidirectionally, while phloem transports water bidirectionally.

• Xylem transports water bidirectionally, while phloem transports food unidirectionally.

Which of the following statements correctly describes the cellular composition of xylem and phloem tissues?

• Xylem is primarily composed of living cells, while phloem is primarily composed of dead cells.

• Both xylem and phloem are primarily composed of living cells.

• Xylem is primarily composed of dead cells, while phloem is primarily composed of living cells.

• Both xylem and phloem are primarily composed of dead cells.
