• 
• 
• 
• 

The diagram shows the adaptation of plant roots to a habitat. Which of the following is NOT a characteristic of root adaptation of the plant to adapt to environment conditions?

Which of the following is an adaptive characteristic of a floating plant to carry out photosynthesis?

• The leaves are small and thick

• The stoma is scattered mostly on the lower epidermis of the leaves

• The upper epidermis of the leaves is covered with waxy cuticles that are waterproof

• Plant stems composed of sclerenchyma tissue

The following are the importance of thorns on xerophyte plants except ....?

• Reduces the amount of surface exposed to the sun

• Reduces water loss

• Increase the total number of stoma

• Helps collect dew for water supply purposes

Why do halophytes and xerophytes have sunken stomata?

• To increase the rate of gas exchange

• To reduce the rate of transpiration

• To increase the rate of photosynthesis

• To reduce the plant temperature
