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

Page 4: Biologi - Adult Tissue

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

Page 5: Biologi - Adult Tissue

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

Page 6: Biologi - Adult Tissue

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

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

Page 8: Biologi - Adult Tissue

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.

Page 9: Biologi - Adult Tissue

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

Page 10: Biologi - Adult Tissue

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.

Page 11: Biologi - Adult Tissue

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

Page 12: Biologi - Adult Tissue

Sklereid

Are plant cells that has die.

Circular shape and have

thick cell wall.

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

Page 15: Biologi - Adult Tissue

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.

Cork Tissue

Page 19: Biologi - Adult Tissue

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.
