Tick all features/characteristics of the tropical rainforest.
Dense forests and trees grow close together
Supports large biodiversity of plants and trees
Evergreen
Trees are very tall
What are evergreen trees?
Trees that have leaves in spring.
Trees that have leaves during the winter.
Trees that have leaves all year long.
Trees that flower during the summer.
Which of the following is/are the characteristic(s) of the leaves in tropical rainforest?
waxy surface
drip tip
leathery
needle-leaved
Many of the leaves are very broad which helps them to absorb ____________
wind
oxygen
carbon dioxide
sunlight
Which of the following is the function of drip-tip leaves?
To compete for sunlight
To stand against strong winds
To drain rainwater quickly to prevent bacteria growth
To reduce water loss from transpiration
Leaves have waxy, leathery or hairy surfaces to minimise loss of moisture through _____________.
transpiration
condensation
photosynthesis
evaporation
Flowers in the rainforest need to be pollinated by insects. Why?
Because there is a lot of insects
Because there is limited access to bees
Because there is limited wind
Because there is a lot of flowers to compete against
Barks are smooth to ensure that _________.
Rainwater is trapped
Rainwater is collected
Rainwater flow easily from the crown to the roots
Rainwater flow up
Branches are ______________ to help trees obtain maximum sunlight.
short and narrow at the top
short and wide at the top
widening at the top
wide-spreading at the top
Roots are shallow and spreading to _________.
absorb nutrients on the top soil
absorb nutrients from the branches
absorb nutrients from the plants
absorb nutrients from the air
Buttress roots shown in the photo helps to ____________.
absorb nutrients from the topsoil
absorb water
anchor the tall emergent trees firmly on the ground
Colourful and sweet-smelling flowers and fruits help to _________.
attract insects for pollination
attract animals for seed dispersal
attract insects for pollination and animals for seed dispersal
attract humans to pluck them
Which of the following statement best describes what is shown in the diagram?
Water vapour is released into the atmosphere through transpiration.
This encourages cloud formation and rain, which replenishes water in rivers and reservoirs, thus increasing water quantity.
Leaves and branches intercept rainfall and enable more water to infiltrate into the ground. This water will be stored as groundwater and eventually flow into rivers and reservoirs, thus increasing water quantity.
The roots hold the soil particles firmly to the ground. This results in fewer soil particles entering the water bodies. Therefore, water quality is good.
Rainforest is regarded as the "____ of the Earth".
Head
Heart
Eyes
Lungs
The photo shows the central catchment area in Singapore.
Which of the following statement best explains why quality of water in the reservoirs is high.
There are no buildings near the reservoirs.
The reservoirs are surrounded by rainforests. Roots of the trees hold the soil firmly to the ground which prevents soil particles from entering the water bodies.
The canopy intercept rainfall, preventing soil erosion.
The trees released water vapour into atmosphere through transpiration, which encourages cloud formation and rain.
The _______ temperature and _______ rainfall allows a large variety of species to thrive in the rainforest.
high, low
low, high
high, high
low, low
Tropical rainforests are also known as the _________ as they have been a huge source of medicine.
"Green lungs of the world"
"World's largest pharmacy"
"World's most sacred forests"
Which of the following are valuable uses of the tropical rainforests? Tick all that apply.
Maintain quantity of water in the environment
Maintain quality of water in the environment
Purify the atmosphere
Provide a habitat for flora/fauna and indigenous people
