Botany lec - Tissues

These are undifferentiated or rapidly dividing tissues.

• Meristematic tissues

• Permanent tissues

• Both

This is the meristem that increases the diameter of the stem.

• Apical

• intercalary

• lateral

This is a primary meristem in vascular plants that gives rise to epidermis

• Procambium

• Ground meristem

• Protoderm

• intercalary

It is a thick layer of non living cork cells and a protective tissue that replaces the epidermis when the secondary growth displaces.

• Epidermis

• Periderm

• Vascular tissue

• Ground tissue

These are tissues which are thickened with lignin and are dead at maturity

• Collenchyma

• Parenchyma

• Chlorenchyma

• Sclerenchyma

These vascular tissue is composed of sieve tubes and companion cells

• Xylem

• Phloem

• xylem vessel

• tracheids

These are perforated walls with an end walls to allow cytoplasmic connections between vertically-stacked cells and no nucleus.

• sieve elements

• companion cells

• tracheids

• vessel elements

This tissue functions to transport food, water, and minerals

• dermal tissue

• ground tissue

• vascular tissue

It functions to provide flexibility support.

• Collenchyma

• Parenchyma

• Sclerenchyma

• Aerenchyma

Parenchyma, Collenchyma, Sclerenchyma are classified under:

• Dermal tissues

• Ground tissue

• Vascular tissue
