BRIEF INTRODUCTION
Hi I am Liam! Today we are
going to find out what are the
specialized structures of
Terrestrial plants?
Hi I’m Amare! But
before that, let’s find
out first what plant
needs in order to grow.
Here are the factors that affect the plants growth.

5
SOIL
Hi there! I am Soil
Plants grow in fertile and nutrient-rich
soil. Plants cannot grow in infertile soil
because there are no nutrients for the plant to
feed on, so there is nothing to promote growth
and maintenance of the plants. Aside from
that soil provides an anchor for plant roots and
helps support the plants.
But do plants grow
with the same type
of soil?
Depending on their habitat, different
plants require different types of soil to
grow. For instance, cactus grows well in
sandy soil. Each soil type differs in its
nutrient content and water-retention
Hi! I’m water, like humans
and animals, plants need
both water and nutrients
(food) to survive.

6
Hello friends I am Sunny, the
Sunlight Plants cannot perform
photosynthesis in the absence of
sunlight. If photosynthesis does
not occur, plants cannot prepare
starch, and they eventually die.
Plants produce
oxygen. Do they still
need air?
Yes, Plants need carbon dioxide from
air to perform photosynthesis. About
0.03 percent of air consists of carbon
dioxide, which is released in the air by
respiration of animals, combustion of
fossil fuels and decomposition of
Now let us study the specialized structures of Terrestrial Plants.
What are Terrestrial Plants?
 Terrestrial plants are plants that grow on land.
 Some Terrestrial plants are small, others are big.
 There are plants with big trunks while others have soft stem.
 Other plants bear flowers while others do not.
 Terrestrial plants grow in different places and can adopt to varied conditionshowever;
their structures are suited to particular needs. Roots of the plants adopt themselves to
their habitat.

https://www.slideshare.net/reflective_learning/plants-adaptation-26586987
Autotrophic plants contain a
green pigment called
chlorophyll, which is necessary
for photosynthesis. Chlorophyll
traps heat from sunlight and
initiates photosynthesis

7
DESERT PLANT
Cactus is a desert plant, it can survive in a hot-dry
climates. They have thick, fleshy stem with waxy skin. The Stem
stores water and the tough skin keeps the water from
evaporation.
SEASHORE PLANTS

vector/coconut-trees-in-the-seashore-vector-1178902
https://www.pinterest.ph/pin/1459448441536
91962/?nic_v1=1aEVG5xrd268ygojnYbB4PCxv6
Coconut tree can live near the ocean because they have
specialized structure toconvert salty water into fresh water.
They enjoy sandy soil, and are wind tolerant.
GRASSLAND
Grasslands have strong roots and flexible stems so
they cannot be pulled or broken by strong winds. They have
small leaves to ensure reduce water loss.
Ex: Buffalo grass land, fleabane and milk weed.
https://www.britannica.com/science/grassland
Shapes and size of the leaves are also important for survival
https://www.shutterstock.com/search/taro+leaf
Plants like bananas produce big, broad leaves to efficiently trap
more energy from the sun.

Plants with waxy leaves help to protect themselves
from dehydration as a result of too much exposure to the
sunlight. Taro leaves is the best example of it.
https://www.garden.eco/banana-tree-care
MOUNTAIN REGIONS
The trees in mountain regions are conical shaped with sloping
branches. The leaves of plants are needle like in shape which helps
rainwater and snow to slide off easily. Pine tree, deodar and fir are
the best example.
https://en.wikipedia.org/wiki/Pine#/media/File:Pinus_
densiflora_Kumgangsan.jpg
TROPICAL RAINFOREST
Trees in such forests are of great height to reach the maximum sunlight as very little
sunlight reaches the ground that is why plants at lower levels have big, broad leaves to absorb
sunlight. Spider orchids, laurel bush and boxwood are the best example.
Activity 1.1: Can you feel me!
Objective: Describe the specialized structures of Terrestrial Plant
Direction: Draw a Happy face  if the statement is correct and sad face  if it is incorrect.
1. Desert plants lose very little water through transpiration.
2. Grasslands have strong roots and flexible stems so that they cannot be pulled or
broken by strong winds. They have small leaves to ensure reduced waterloss.
3. Terrestrial Plants grow in different places, there are plants that grow directly on the
soil while other grow on rocks.
4. Shapes and size of the leaves are not important for survival
5. Plants with waxy leaves help to protect themselves from dehydration.
6. Coconut tree cannot leave near the seashore
7. Cactus is the best example of desert plant.
8. Roots of the plants adapt themselves too to their habitat.
9. Terrestrial plants are plants that grow in water.
10. Most number of Terrestrial plants are found in the fields.

 Terrestrial Plants are plants that grow on land. They grow in different places.
Like desert, seashore, mountain region, tropical rain forest and most of them
are found in the field.
 Roots, leaves, and stem of the plants adapt themselves to their habitat.They
deeper in size and shapes too. These characteristic are determine by their
function
 Plants with waxy leaves help to protect themselves from dehydration as aresult
of too much exposure to sunlight
 Some stems have thorns that provide protection. Some have thick stem that
store water when the habitat does not provide it.
1. How do terrestrial plants adapt to their environment?
2. What can you find on the stem of the cactus?
Activity 1.2: Plant Puzzle
Objective: Identify the things that plants need in order to grow healthy.
DIRECTION: The letter on the left are all mixed up. Arrange them to spell out the correct word.
The clues on the right side will help you.
1. THESISSTOYNHOP - Plants cannot perform it in the absence of sunlight.
2. BONXIDECARDIO - Released in the air by respiration of humans and animals.
3. SUTCAC- Grows well in sandy soil.
4. PROHCHYLLOL- Traps heat from sunlight and initiate photosynthesis.
5. LISO - Provides an anchor for plants and roots and help support the plants.

Specialized Structures of Aquatic Plants
BRIEF INTRODUCTION
What are Aquatic Plants?
 Aquatic Plants are plants that have adapted to living within aquatic environments.
 They are also referred to as Hydrophytes.
 These plants require special adaptations for living submerged in water or atthe
water’s surface
 Aquatic Plants can only grow in water or in soil that’s is permanently saturated with
water.
 Aquatic plant are plants that have adapted to living in aquatic environments(saltwater
or freshwater). They are also referred to as hydrophytes or macrophytes.
FREE-FLOATING MACROPHYTES
Are aquatic plants that are found suspended on water surface with their root not
attached to substrate or sediment or bottom of water body. They are easily blown by air and
provide breeding ground for mosquito.
Examples: Pistia commonly called water lettuce, water cabbage or Nile cabbage,
lemna salvinia and azolla

ia/Plik:Salvinia_natans_(habitus)_1.jpg
Fixed Plants
Have roots which are fixed to the bottom of the pond. Have
long hollow stem to reach the surface of the water and have
broad and waxy coated leaves to prevent them from rotting.
Lotus and water lilies developed wide leaves that allow
them to float on water. Lotus and lily are example.

11
Underwater Plants
These have narrow leaves without any stomata. They breathe through the surface and keep
the water clean. Examples: Tape grass and pond weed

Pond Weed Tape Grass
https://en.wikipedia.org/wiki/File:Red_mangrov
e-everglades_natl_park.jpg
Mangroves have the ability to survive in waterlogged and anoxic (no oxygen) soil. And the
ability to tolerate brackish water. Some of them have the ability to remove salt from the brackish
estuarine water through ultra- filtration in their roots. https://www.slideshare.net/reflective_learning/plants-
adaptation-26586987
