16 March 2020 Title: Adaptations in the Tropical Rainforest
Write down what plants
need to survive, and why.
What do plants really need to stay alive?
•Water
•Light
(photosynthesis)
•Warmth
•Nutrients
•Able to reproduce
Tier 2 Key Word: Adaptation
To adapt is to change to suit new conditions or for a purpose
How have you ever had to adapt?
How do you adapt to certain kinds of
weather?

Have a look at the graph and the important fact below. Why
are the conditions excellent for plants in the tropical
rainforest?Important
fact:
Almost 12
hours of
sunlight
every day

Plants in rainforests are therefore very lucky because potentially they
have:
Lots of rainfall + always warm + lots of light

In the rainforest there is the highest level of plant
adaptation on the planet!
This is because all the plants are fighting for the
same things – sun, rain, heat!
The 4 layers of the rainforest you learnt about last lesson
were created by this level of competition.

in the rainforest
In each layer of the rainforest, what do plants need to adapt to, to be able to survive.
1. Forest floor/Shrub layer2. Under canopy3. Canopy4. The Emergents
What is the weather like there? Sun? rain?Is it dark or light?
On the forest floor it is very dark and wet so plants need to adapt to be able to survive there.In the under canopy …In the canopy…At the top, the emergent…
Buttress roots Epiphytes Drip tip leaves Lianas Pitcher plants
Large roots Plants that live on
the trunk and
branches of other
plants
Shaped to allow
water to run off to
the roots
Found climbing the
trunks of trees
Has sweet smelling
nectar to attract
insects
Grow very fast Allows water to
runoff the plant very
quickly avoiding
burning
Has a “pitcher” or
jar shape to collect
water
Searching roots
which help to
collect most of the
nutrients in the soil
Often found just
beneath the canopy
Has a very sticky
inside to stop
creatures crawling
out.
Take advantage of
the sunlight that
filters though to the
under canopy
Have coils in the
stem to stop them
snapping if put
under pressure
Found on almost all
plants in the
rainforest
Gives tall emergent
trees a stable base
Climb all the way
from the canopy to
reach sunlight
Take water and
sugar out of the
tree branches
Not damaged by
heavy rain
We are going to look at few
examples of plants that have
adapted to life in the
rainforest…
Cut out the pictures and we are going to label them one by one.
Buttress Roots
Trees in the rainforest have
very shallow roots.
But tall trees need support to
stop them from falling over.
They have developed
Buttress Roots which grow
from the base of the tree and
can be as tall as 15feet
above the ground!
Another form of buttress root (tilt or Prop Roots)
Epiphytes
These plants grow
on the tree without
soil.
The seeds get
blown high up the
tree.
Here they are able
to get more light.
The roots steal
water from the
tree.
Drip Tip Leaves
Almost all plants in
the rainforest have
these kinds of leaves.
These leaves make
sure the rain runs off
the leaves and
doesn’t damage the
leaf.
Bromeliads
Their thick, waxy leaves form a bowl shape in the centre for
catching rainwater.
These plants provide a home for several different animals.
Lianas
These are thick, woody
vines that can be found in
the rainforest.
They can be up to 1km
long!
They start growing on the
forest floor but grow
upwards to get the sun
they need to survive.
Pitcher Plant
This plant catches small
animals like spiders and
ants.
It has adapted in this way
because there are very little
nutrients available on the
forest floor.
It smells sweet to attract
insects!
What does it look like?
Tree trunks are
straight and do
not have
branches in the
lower part so
they can grow
taller.
All the branches
and leaves grow
at the top of the
tree to catch the
sunlight

Quiz: Which adaptation/living thing is being described here
1. Stops the plant from being damaged by the rain.
2. Helps trees to get lots of nutrients (good stuff) from the soil.
3. Supports emergent trees (the tall trees)
4. Lives close to the forest floor.
5. Grow very quickly to reach the light in the canopy.
6. Do not have roots on the ground.
7. Rely on animals to get nutrients (good stuff)
Task:
1. How would you need to adapt to live in the rainforest?
OR.
2. How could this plant adapt to live in the rainforest to make sure it gets sun, rain, heat or nutrients (food)?
OR.
3. Design your own plant with adaptations, draw it and label each adaptation with an explanation of how it helps the plants.
