FBS 6 QUIZ

This word best describes the cell wall growth in different direction.

• isotropic
• symmetric
• homogeneous
• anisotropic

The elongating organ in a young, emerging seedling is called as ________.

• radicle
• hypocotyl
• epicotyl
• plumule

What is the importance of anisotropy in cell growth?

• Anisotropy in cell growth is important for cell division and replication.
• Anisotropy in cell growth is important for cell polarization, tissue development, and organ formation.
• Anisotropy in cell growth is important for maintaining cell shape and structure.
• Anisotropy in cell growth has no importance in cell polarization, tissue development, and organ formation.

This could be used to measure cell wall mechanical properties.

• Atomic force microscopy (AFM)
• Scanning electron microscopy (SEM)
• Confocal microscopy
• Transmission electron microscopy (TEM)

If material anisotropy refers to the direction of growth, the stiffness or elasticity of cell wall determines the ______________of growth.

• magnitude

• speed
• direction

• intensity
