Plant Adaptation 2

2. Recall…
• Adaptation is the ability of plants to
survive in its habitat.
• A habitat is a place where plants and
animals live.
• Some plants grow better in some
regions or habitats while others do not
• Plants adapt to these regions after
several years due to the condition of
the region.

3. • Adaptation
• Habitat
• Region
• Submerge
• Waxy
• Coated
• Fibrous
• Insectivorous
• Coastal
• Mangrove

5. •List regions were plants can be found
•Give examples of plants
•Identify their adaptive features

6. Plants can be found growing in different regions like -
DRY DESERTS
PLAINS
SNOWY MOUNTAINS
COOL COASTAL
CALM LAKES

7. Plants have developed special features that allow them survive in these
different environments.
• Features that may allow a plant to grow in one habitat may make it difficult for that
same plant to grow in other habitats.
• Pine Trees survive in cold regions while it can not survive in water like the water lilies
• This is why some plants can be found in one region and cannot be found in other
regions

8. Plants are categorised into -
PLANTS
TERRESTRIAL
PLANTS
AQUATIC
PLANTS

9. Terrestrial plants are plants that grow on land.
They can be found in the following regions -
MOUNTAINS PLAINS DESERTS SWAMPSCOASTS

10. Mountain/Hilly Regions
Plants that grow in this region are –
pine, fir, spruce, cedar trees etc.
Adaptive Features
• Shaped as cones.
• Allow snow to slide off it.
• Have waxy and needle-like leaves
and cone shaped seeds instead of
flowers to prevent snow from
damaging them.

FIR CEDAR
SPRUCE

11. Plains Region
Plain regions are flatlands. Plants here can
bear the heat of summer and are called
deciduous trees.
Adaptive Feature
• Leaves are small to prevent excessive loss
of water
• Shed leaves in autumn- shedding helps
prevent water loss in winter, when
season changes they grow back new
leaves
• Roots grow deep into the groundelm

12. Desert Region
This region is covered with sand and has very little
rain. Plants in the desert are cactus, date palms
and prickly pear.
Adaptive Features
• Their roots grow long and wild to help them get
water
• They usually do not have leaves or the leaves
are reduced to spines which prevent water loss
as a result of the hot weather
• The stem is green and fleshy which stores water
and makes food for the plants.

13. Coastal Region
Coastal area is a region close to a water bed.
The soil there is grainy and loose. Example of a
plant in the coastal region is the coconut tree.
Adaptive Features
• Fibrous and flexible stem to withstand heavy
wind and rainfall or flood.
• The fruits have a thick fibrous coat which
help them float in water and to disperse
their fruits and seed.

14. Swamp Region
Mangroves plants are plants found in
marshy or swampy areas. They do not have
sufficient air to breathe as the soil is
swampy and filled with water.
Adaptive Feature
• They develop breathing roots which grow
above the surface of the water or soil to
get enough air.

15. Are called insectivorous plants because they both eat insects for food

16. Aquatic plants Plants that grow in water
Free
Floating
Fixed
Plants
Underwater
Plants

17. Free floating plants
Plants like water hyacinth and duckweed do not have fixed roots but
float freely on water. The stems and leaves are light and spongy.

18. Fixed plants
• Fixed plants like water lilies and lotus have their roots fixed to soil at the bottom
of the lake or river.
• Thin, long hollow, flexible stems to withstand water currents.
• Leaves are broad and flat which helps them float on water.
• Leaves are covered with waxy coating to prevent rusting as a result of too much
water.
• Leaves have small pores called stomata so water does not block the pores.
• Flowers are large and bright which help floating and attract insects for
pollination.
Water lily Lotus

19. Underwater plants
Underwater plants like tape grass and pond weeds are not usually visible
on the surface of water.
• Roots are fixed on the soil at the bottom of the pond
• Thin narrow leaves to withstand water currents
• Leaves do not have stomata.
• They breathe through their body surfaces

20. 1. Which adaptation helps plants in hilly regions to face high speed
wind?
A. The adaptation that helps "plants in hilly areas" to face "high speed winds"
and "cold" is the conical shape and needle shaped leaves. The conical shape
of the trees in hilly areas, helps the plant to survive, by sliding off and getting
rid of the snow or ice that falls on the trees.
2. What are the adaptations of plants that grow in Plains?
A. The leaves are small to reduce moisture loss, shed leaves during winter to
reduce water loss and the root grow deep into the ground.

21. Today, we have learnt that…
• Plants can be found in different regions and can adapt to several
environmental conditions.
• The regions are mountains, plains, deserts, coastal, swamp and
aquatic regions.
• There are 3 types of aquatic plants – free-floating, fixed and
underwater plants.
• Plants needs to adapt to their environment so they can survive.
