Plant Tissues Flashcards

Flashcards covering the organization of plant tissues, including epidermis, ground, and vascular tissues, and their respective functions.

Permanent Tissues

Matured tissues that have already undergone differentiation or are currently undergoing differentiation process.

Epidermis Tissues

Found on the outer surface of stems, leaves and roots of young plants.

Cuticle

A waxy and waterproof layer on the epidermal wall that helps to minimize water loss through evaporation (transpiration), provide protection dan prevent entry of pathogens.

Guard Cells

Modified epidermal cells that control the opening and closing of stoma for photosynthesis.

Root Hair Cells

Modified epidermal cells that help to increase the surface area for absorption of water and mineral salts.

Parenchyma Tissues

Simplest living cells that are not differentiated yet, arranged in a turgid state to provide support and maintain the shape of herbaceous plants, carry out photosynthesis, store starch and glucose, involved in gaseous exchange, repair and regeneration of plant tissues as well as transport of vascular system.

Collenchyma Tissues

Living cells which become flexible upon maturation, give mechanical support and elasticity to the plants.

Sclerenchyma Tissues

Made up of matured dead cells, support and strengthen matured parts of the plant, help in the transport of water and nutrients.

Xylem

Made up of dead cells without cytoplasm, transport water and mineral salts from the roots to other parts of the plant.

Phloem

Made up companion cells and sieve tubes (living cells that contain cytoplasm), transports glucose formed from photosynthesis from the leaves to the roots, fruits and tubers to be stored.
