3. Protection Tissue » Epidermis Tissue
Characteristic:
1. Consist of living cell
2. Rectangular in shape
3. Compact cells & don’t
have has space
4. Don’t have chlorophyll
5. Able to forming derivate of
epidermis tissue
4. Function:
1. Protect the inner part of plant organ
2. Protect the plant from losing water
from transpiration, mechanical
damage, change of temperature and
lack of nutrition
Location:
Surface of plant organ
5. Stomata
Stomata or leaf mouth is gap
in epidermis tissue that border
by two guard cell.
Function:
1. The way for enter of CO2
from air and exit of O2
during photosynthesis
process in daylight
2. Transpiration route
3. Respiration route, the
entering of O2 and exit of
CO2
6. Trichomes
Trichomes are
modification of epidermal
tissue as hairs.
Function:
1. Reduce evaporation
2. Relay stimulus
3. Reduce disturbance
from human & animal
4. Help seed distribution
5. Help seed germination
7. Strengthener Tissue » Parenchyme Tissue
Parenchyma are ground
tissue that found in almost
all of plant organ.
Characteristic:
1. Living cells with large
size & thin wall. Mostly
hexagonal.
2. Have many vacuola
3. Nucleic are close to the
cell base
4. Meristematic
8. 5. Have a lot of interstitial
Function:
1. Produce food through photosynthesis process in
Assimilation Parenchyma
2. Store excess food in Storage Parenchyma
3. Holds water in Water Parenchyma
4. Transport water & nutrient (near xylem) and
distribute the photosynthesis’s product (near
phloem) in Vascular Parenchyma.
Location:
Present in epidermis until pith and between xylem &
phloem.
9. Connective Tissue » Collenchyma & Sclerenchyma
Tissue
Connective tissue are tissue
that act to support the shape
of plant body to stand up
right.
Function:
1. Strengthen the upright
position of stem & leaves
2. Protect the seeds
3. Strengthen parenchyma
tissue that store air.
4. Protect vascular bundles
10. Collenchyma
Collenchyma is living tissue
that shows a lot of
parenchyma characteristic.
Function:
To supporting and strengthen
tissue of plant organ.
Location:
Can found in above of
young stem surface and
handle of young leaves.
11. Sclerenchyma
Is connective tissue that can
found in adult plant.
Characteristic:
1. Thick cell wall
2. have lignin & cellulosa
3. Inactive protoplasm when
adult
Function:
As connective and protection
Location:
In various place in plant organ
14. Transporting/Vascular Tissue » Xylem & Floem
Characteristic of Xylem:
1. Consist of death cells and living
cells.
2. Cell wall impregnated with lignin
3. The cells are in lines and form
vascular bundle
Function:
1. Distribute water and nutrient
from the root to the leaves.
Location:
Can found in stem and root
15. Characteristic of Phloem:
1. The cells like pyramid
Function:
1. To distribute the photosynthesis
product from leaves to all of the
part of plant
Location:
Can found in stem and root.
19. Cork Tissue
Is tissue that composed by cork parenchyma cell.
Characteristic:
1. Cork cell are long with cell wall that cork-
containing
2. In death cork cell, protoplasm is gone and replace
by air.
Function:
To protect other tissue in under of them from
drought and mechanical disturbances.
Location:
Can found in under of epidermis.
