A large number of stomata
Leaves have modified into thorns
Poor root growth
Which of the following cause the highest rate of transpiration in well-watered mesophytes?
Windy, cool, high humidity, bright sunshine
Windy, hot, high humidity, cloudy
Still air, hot, high humidity, bright sunshine
Windy, hot, low humidity, bright sunshine
Which of the following is an adaptation found in a plant lives in high salt content?
Thick and succulent leaves
Stomata that open during the night
Thin and waxy cuticle
Ability to shed leaves
Which of the following can be classified as mesophytic plants?
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?
Provides support to survive in soft and muddy soil
Prevent plants from falling due to strong winds
Plant root's cell sap has lower salt content than seawater
There are lenticels on the roots
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
Halophytes live in an environment that is ...........
acidic
alkaline
sandy
salty
Mangrove swamp contains high salt concentrations and low oxygen. What are the adaptive features of the plants that live in this area?
The leaves have a special structure called hydathode
The mangrove tree has breathing roots called pneumatophores
The leaves are needle-shaped
The leaves are thin and wide
A plant has a waxy cuticle, reduced leaves and reduced number of stomata. What type of plant could this be?
Hydrophyte
Halophyte
Mesophyte
Xerophyte
Which feature is ABSENT in a completely submerged hydrophyte?
Short and thin root structure
Stoma on the upper surface of leaves
Abundant of aerenchyma tissues
Diagram shows a cross-section of a stem of a plant. What is the importance of the stem structure?
Provide support to the plant
Reduces the density of plant
Increases the rate of gaseous exchange
Absorb maximum sunlight
