3. Root
Root Structure
1. Morphology
Devided 2 types;
ďMonocotyledon such as Corn, Sugarcane,
Coconut, their root type are fibrous root.
ďDicotyledon such as Mango and Chilies,
their root type are tap root.
ďRoot can find the water in the soil, with
the protector named Calyptras.

5. 2. Anatomy
Root divided
into 3 parts ;
a. Region of
Maturation
b. Region of
Elongation
c. Apical

7. Parts of the Root
â˘Epidermis
â˘Cortex
â˘Endodermis
â˘Stele

8. Function of Root
ďThe main function is to absorb water and
minerals which is dissolved inside from the
soil
ďTo straighten the plant
ďAs the food storage in certain plants such as:
Cassava, Carrots
ďAs vegetative reproduction organ, ex. spruce
ďAs respiration organ in Mangrove

9. Stem
⢠Stem was from a
part of embryo in
the seed.
⢠Commonly, stem are
heading up from the
soil to the air.
⢠As long as their
growth period.
Created by Alfie_MSK, A Biology teacher of
GIS JH
10. Structure of Stem
1. Morphology
⢠Hard
⢠In young stem, there
are some clorophile so
they can do the
photosynthesis
⢠There are some small
dots in certain parts of
stem, called Lenticels
⢠Monocotyledon and
Dicotyl difference in
branching of the stem

11. Dicotyl stem Monocotyl stem

with root ;
ďEpidermis
ďCortex
ďEndodermis
ďStele

14. Factors of Dicotyl Monocotyl
Differentiation Stem Stem
Place of the In Order Spread
Veins
Cambium There is for No
secondary
growing
Created by Alfie_MSK, A Biology teacher of
GIS JH
15. Function of Stem
⢠As the way to deliver
water, mineral, and
photosynthesis
results
⢠As the place to attach
the leaves
⢠As respiration system
in Lenticels
⢠To direct the leaves
to light source such
as Phototropic
activity
Created by Alfie_MSK, A Biology teacher of
GIS JH
16. ⢠In certain plants stem
used for a special purpose
such as:
ďAs the food storage such
as Sagoo, Sugarcane
ďAs water storage such as
Cactus
ďAs reproduction system
such as Tapioca Tree

17. Leaves
⢠Leaves was
from a part of
embryo in the
seed which is
cotyledon
⢠The green color
came from the
chlorophyll
Created by Alfie_MSK, A Biology teacher of
GIS JH
18. Structure of Leaves
1. Morphology
⢠Consist of leaf midrib,
petiole, leaf blade
⢠A complete leaf can be
founded in areca nut leaves
⢠There are so many forms of
leaves
⢠Circular
⢠Oval
⢠Shield-Shaped
⢠Ribbon-Shaped
Created by Alfie_MSK, A Biology teacher of
GIS JH
20. Anatomy of Leaves
⢠Cuticle Layer
⢠Upper
epidermis
⢠Mesophyll
⢠Vascular
bundles
⢠Lower
epidermis
Created by Alfie_MSK, A Biology teacher of
GIS JH
21. Leaf in Photosynthesis Activity
⢠Usually the water was
extracted through 2
ways:
⢠Vaporization through
process of transpiration
⢠Water molecules
through process of
⢠Transpiration through
stomata
⢠Stomata came from
Greek language meaning
mouth, stomata is the
plural version of stoma
Created by Alfie_MSK, A Biology teacher of
GIS JH
22. About Stomata
⢠Usually Stomata was
placed in epidermis layer
of leaf wherever lower or
upper layer
⢠Stoma consist 2 closing
cells/ guarding cells/ cell
protector shape like liver
and had many
chlorophyll
⢠There are little amount of
closing cells than the
total of epidermis cells in
the layer
Created by Alfie_MSK, A Biology teacher of
GIS JH
24. Function of Leaf
⢠As we know, leaf act
as the place for the
Photosynthesis
⢠The chlorophyll in
the leaf was one of
the required
component for the
process of
Photosynthesis
⢠Also as Transpiration
and Respiration Created by Alfie_MSK, A Biology teacher of
GIS JH
25. Transpiration
⢠The vaporization of the
water through stomata,
cuticle layer, and lenticels
⢠The truth is, transpiration
happen in all parts of the
plant, but the biggest
transpiration process is in
leaf
⢠Why in leaf? Because leaves
layer are the widest surface
between the others
⢠Transpiration in day times
are much more through
stomata
⢠In night, through cuticle
Created by Alfie_MSK, A Biology teacher of
GIS JH
26. Flower
⢠Flower is a
reproduction
organ in the plants
generatively in
Angiosperm plants
⢠In Gymnosperm
plants, it called
strobilus

28. Fruits
Parts of Fruit
ďś Epicarp as the
outer layer of fruit
ďś Mesocarp as
middle layer which
is thick part of fruit
ďś Endocarp the inner
layer of fruit
ďś Seed as the core of
the fruit
Created by Alfie_MSK, A Biology teacher of
GIS JH
29. Types of Fruit
⢠âReal Fruitâ such as
Papaya, mango, and
durian.
⢠âArtificial Fruitâ such as
Jackfruit, apple, and
pineapples.
⢠âSimple Fruitâ such as
tomato and soya bean.
⢠âDouble Fruitâ such as
Strawberries.
⢠âCompound Fruitâ such
as Pineapples.
Created by Alfie_MSK, A Biology teacher of
GIS JH
31. Function of Fruit
⢠As the food storage
⢠To radiate the plants
⢠To attract the bird to eat them along the hard
seed
⢠Then birdâs feces made a new individual seed
⢠Then the seed grow as a new plant
Created by Alfie_MSK, A Biology teacher of
GIS JH
32. Seed
⢠Part of the plant made
from the results of
fertilization
⢠Which is placed in the
ovaries
⢠In the ovaries, there are
ovules
⢠In the ovules.. There are
also the embryo as the
candidate of new
individual plant
