Plant Cells & Tissues

CHS Advanced Biology students will use these flashcards to study specific plant cells and tissues
parenchyma cell
Flexible, thin-walled, spherical cells that perform a wide range of functions.
collenchyma cell
Plant cells that are elongated and occur in long strands or cylinders that provide support for surrounding cells.
sclerenchyma cell
Plant cells that lack cytoplasm when they mature, but retain their thick, cell walls.
Regions of rapidly dividing cells
vascular cambium
A thin cylinder of meristematic tissue that can run the entire length of roots and stems.
cork cambium
Produces cells that develop tough cell walls that form a protective outside layer on stems and roots.
The layer of cells that makes up the outer covering on a plant.
guard cells
The two cells that form a stoma.
The water-carrying vascular tissue that is composed of vessel element and tracheid cells.
vessel elements
Cells in the xylem tissue that are tubular and stacked end to end forming long strands.
Long, cylindrical cells in the xylem that have pitted ends.
The main food-carrying tissue in vascular plants.
sieve tube members
Cells in the phloem tissue that lack a nucleus, but are long and cylindrical for conducting sugar water.
companian cells
Cells in the phloem tissue that have a nucleus and assist the sieve tube members.
ground tissues
Consist of parenchyma, collenchyma, and sclerenchyma cells and have diverse functions, including photosynthesis, storage, and support.
