Plant Tissue Cells

Types of Plant Tissue Cells

Meristematic cells: undifferentiated cells that have the ability to divide and differentiate into different cell types
Permanent cells: differentiated cells that have a fixed structure and function
Parenchymatous cells: living cells that provide support and storage functions
Collenchymatous cells: living cells that provide mechanical support and flexibility
Sclerenchymatous cells: dead cells that provide mechanical support and protection
Epidermal cells: outermost layer of cells that protect the plant from the environment

Characteristics of Plant Tissue Cells

Cell wall: composed of cellulose, hemicellulose, and pectin
Vacuoles: store water, salts, and nutrients
Plastids: organelles responsible for photosynthesis and pigment synthesis
Lysosomes: organelles responsible for cellular digestion and recycling
Cytoskeleton: provides structural support and shape to the cell

Functions of Plant Tissue Cells

Support: provide mechanical support and structure to the plant
Storage: store nutrients, water, and waste products
Transport: transport nutrients, water, and waste products throughout the plant
Protection: protect the plant from pathogens, insects, and environmental stressors
Photosynthesis: responsible for converting light energy into chemical energy

Specialized Cells

Guard cells: regulate gas exchange and water loss through stomata
Trichomes: hair-like structures that provide protection and reduce water loss
Root hair cells: increase surface area for nutrient uptake
Vessel elements: specialized cells that form xylem and phloem tissues

Plant Tissue Cells

Types of Plant Tissue Cells

Meristematic cells are undifferentiated, can divide and differentiate into various cell types, and are responsible for growth and development.
Permanent cells are differentiated, have a fixed structure and function, and make up the majority of plant tissues.
Parenchymatous cells provide support, storage, and are living cells with a thin primary cell wall and are capable of dividing.
Collenchymatous cells provide mechanical support, flexibility, and are living cells with a thick primary cell wall and are found in petioles and stems.
Sclerenchymatous cells are dead at maturity, provide mechanical support, protection, and are characterized by a thick, lignified secondary cell wall.
Epidermal cells are the outermost layer of cells, protect the plant from the environment, and are covered in a waxy cuticle.

Characteristics of Plant Tissue Cells

The cell wall is composed of cellulose, hemicellulose, and pectin and provides structural support and protection.
Vacuoles are membrane-bound organelles that store water, salts, and nutrients.
Plastids are organelles responsible for photosynthesis and pigment synthesis, and are found in plant cells.
Lysosomes are membrane-bound organelles responsible for cellular digestion and recycling.
The cytoskeleton provides structural support, shape, and movement to the cell.

Functions of Plant Tissue Cells

Support cells provide mechanical support and structure to the plant.
Storage cells store nutrients, water, and waste products.
Transport cells transport nutrients, water, and waste products throughout the plant.
Protection cells protect the plant from pathogens, insects, and environmental stressors.
Photosynthetic cells are responsible for converting light energy into chemical energy.

Specialized Cells

Guard cells are specialized epidermal cells that regulate gas exchange and water loss through stomata.
Trichomes are hair-like structures that provide protection and reduce water loss.
Root hair cells are specialized cells that increase the surface area for nutrient uptake.
Vessel elements are specialized cells that form xylem and phloem tissues and are responsible for transporting water and nutrients throughout the plant.
