Experiment 4 Flashcards
Forms the bulk of plant ground tissue
Parenchyma cells
Proliferative cells of the plant found in all plant tissue systems
Parenchyma cells
With thin cells, parenchyma cells are capable of further ______
Cell division
Function of parenchyma cells
photosynthesis, storage, or transport
The ___ and ________ of the plant shoot and roots are equipped with parenchyma to provide new cells for growth
Apical and lateral meristem
Photosynthesis occurs in specialized parenchymal cells called _______
Mesophyll cells
Shapes of parenchyma cells
angular and loose
Comprises many soft tissues of plants
Parenchyma cells
Simple plant tissue, consisting of only one cell type.
Collenchyma
Elongated, living cells that occur especially in peripheral positions in leaves and stems of eudicotyledons.
Collenchyma
Function of Collenchyma
Support structure
Mechanical strength
Flexibility
a plant tissue that consists of living usually elongated cells with unevenly thickened walls and acts as support, especially in areas of primary growth.
Collenchyma
a specialized tissue, adapted to withstand both compressive and tensile stresses in plants.
Sclerenchyma
Function Sclerenchyma cells
provide mechanical support and strength to the plants
Biological stains used in histology and cytology
Safranin
What was the pear stained with
safranin
scientific name of alfalfa
Medicago sativa
Scientific name of pear
Pyrus communis
Scientific name of celery
Apium graveolens
Scientific name of basswood
Tilia americana
acts like armor to protect the body from damage such as ultraviolet (UV) radiation, pathogens (bacteria, viruses, fungi, parasites), and chemicals
Epidermis
Scientific name of squash
cucurbita
an outer layer of tissue immediately below the epidermis of a stem or root.
Cortex
a strand of conducting vessels in the stem or leaves of a plant, typically with phloem on the outside and xylem on the inside.
vascular bundle
composed of soft, spongy parenchyma cells, which store and transport nutrients throughout the plant
Pith
connection sites between sieve elements
Sieve plate
the vascular tissue in plants that conducts sugars and other metabolic products downward from the leaves.
phloem
the vascular tissue in plants that conducts water and dissolved nutrients upward from the root and also helps to form the woody element in the stem.
Xylem
a type of water-conducting cell in the xylem which lacks perforations in the cell wall.
tracheid
Three tissue systems
Dermal, Vascular, and Ground tissue
Coverings of the plant that provide protection by preventing unwanted materials from entering the plant
Dermal Tissue system
the aqueous component of the cytoplasm of a cell, within which various organelles and particles are suspended.
cytosol
tissues that have the ability to enlarge, stretch and differentiate into other types of cells as they mature.
Meristematic tissue
Differences between vascular bundles of monocots and dicots
Monocot stems have bundles of vascular tissue scattered throughout, whereas vascular bundles in dicot stems are arranged in a ring
facilitates the gaseous exchange of oxygen and carbon dioxide
Dermal tissue system
main components of young plants
Ground tissue system
Integral in the packaging and supportive system of the plant.
Ground tissue system
Function of Ground tissue system
Food and storage
