15. Comparison between Primary Growth and Secondary Growth in Eudicots

What are the characteristics of primary growth in eudicots?

• Thin

• Increases the thickness or circumference of stems and roots of plant

• Occurs on stems and roots in younger regions of the plant

• Have woody tissues

Which type of growth increases the length of stems and roots of a plant?

• Both primary and secondary growth

• Primary growth

• None of the above

• Secondary growth

What is the main difference between primary growth and secondary growth in eudicots?

• Primary growth occurs longitudinally, while secondary growth occurs radially

• Primary growth involves cell division by mitosis, while secondary growth involves cell division by meiosis

• Primary growth increases the thickness of stems and roots, while secondary growth increases the length of stems and roots

• Primary growth occurs on woody plants, while secondary growth occurs on non-woody plants

Which part of the plant undergoes secondary growth?

• Epidermis

• Primary xylem

• Bark

• Cortex

What is the main similarity between primary growth and secondary growth in eudicots?

• Both growths involve cell division by mitosis

• Both growths occur in monocotyledons

• Both growths occur in non-woody plants

• Both growths increase the thickness of stems and roots

Which type of growth involves the presence of annual growth rings at the plant stem?

• Primary growth

• Both primary and secondary growth

• Secondary growth

• None of the above

What is the main difference between monocotyledons and eudicotyledons?

• Monocotyledons have secondary growth, while eudicotyledons do not

• Monocotyledons have two cotyledons, while eudicotyledons have one

• Monocotyledons have radial growth, while eudicotyledons have longitudinal growth

• Monocotyledons have woody tissues, while eudicotyledons do not

Which group of flowering plants is the largest?

• Monocotyledons

• Pteridophytes

• Eudicotyledons

• Gymnosperms

What allows some eudicots to grow tall and live for hundreds of years?

• Primary growth

• Secondary growth

• Both primary and secondary growth

• None of the above

Which tissue is involved in primary growth?
