Secondary tissues in a dicot include

• cortex

• xylem

• pith

• cork cambium

Annuals and biennials plants show

• Primary growth

• secondary growth

• no growth

• unlimited growth

Plants that undergo secondary growth

• Mostly monocots

• Short life span

• No woody tissues

• Have woody tissues

What type of vascular tissue is responsible for transporting the sugars made in photosynthesis from the leaves to the roots?

• Cuticle
• Phloem
• Stomata
• Xylem

Which type of plant tissue covers the outer surface of the plant and acts as a protective layer?

• Dermal
• Vascular
• Ground
• Connective

Why is secondary growth important to plant?

• To make sure the plant absorbs sufficient amount of carbon dioxide for photosynthesis

• To ensure that the plant is resistant to pathogen

• To help the plant grow infinitely

• To increase the diameter of both stem and root for additional mechanical support

Some plants have commercial value. Those with commercial value include

I tall, big trees - timber

II Hopea (merawan) - resins and oils

III Hibiscus - ornamental

IV Mango trees - fruits

• I, II and III

• I, III and IV

• II, III and IV
