I Sneezed and Need a Tissue!
Call a Plumber!
Rooted to the Spot
A Bundle of Joy
It's Woody Everywhere!
100
THIS tissue forms the protective OUTER layer of a plant and could be either epidermis or cork. Functions include protection, gas exchange and absorption of mineral nutrients.
What is dermal tissue?
100
THIS is all that is left of a xylem cell at its maturity
What is a cell wall?
100
THESE rows of cells next to sieve tubes do the work of cellular respiration, protein synthesis, and other metabolic functions.
What are companion cells?
100
The stems of herbaceous plants contain THESE bundles of xylem and phloem, which are surrounded by ground tissue.
What are vascular bundles?
100
THIS is the wood in the center of a mature stem or tree trunk. It is made of xylem which can no longer conduct water, but now provides support.
What is heartwood?
200
THIS tissue that makes up much of the interior of nonwoody parts of a plant, including roots, stems, and leaves. It has different functions in different parts of the plant, but it always surrounds and supports vascular tissue.
What is ground tissue?
200
THIS type of xylem cell is found in all vascular plants. It is narrow, elongated, and tapered at the ends. Water flows from one to the next through pits (thin areas in the cell walls).
What is a tracheid?
200
Many dicots (such as carrots and radishes), have THIS kind of root system: a large central root with many branching smaller roots.
What is a taproot?
200
In dicot stems, vascular bundles are arranged in THIS shape.
What is a ring?
200
THIS type of wood, which lies outside the heartwood, contains vessel cells that can still conduct water.
What is sapwood?
300
THIS dermal tissue covers the nonwoody parts of a plant. It is is usually arranged in a flat sheet of cells covered by a waxy cuticle.
What is (plant) epidermis?
300
THIS type of cell makes up conducting strands in xylem. It is wider than a tracheid and has large holes in its ends to let water flow quickly.
What is a vessel cell?
300
Most monocots, such as grasses, have THIS type of highly branched root system.
What is a fibrous root system?
300
THESE pores in the epidermis enable plants to exchange gases with the outside air.
What are stomata?
300
Most leaves have a flattened portion, called the blade, that may be attached to a stem by THIS small structure.
What is a petiole?
400
the outer layer of bark of any woody plant
What is cork?
400
THIS tissue conduct sugars and other nutrients throughout a plant’s body. Its cells have cell walls, cell membranes, and cytoplasm (but lack organelles OR have modified organelles).
What is phloem?
400
Above-ground stems or leaves can sprout from THIS type of root system. The prop roots of corn and the aerial roots of orchids are examples.
What are adventitious roots?
400
In monocot stems, such as that of corn, vascular bundles appear in the ground tissue in THIS pattern
What is scattered?
400
THIS modified leaf protects a cactus.
What is a spine?
500
vascular tissue with thick-walled cells that conduct water and mineral nutrients from a plant’s roots through its stems to its leaves.
What is xylem?
500
THESE cells make up the conducting strands in phloem. Pores in their walls connect cytoplasm and allow substances to pass freely from one neighboring cell to another.
What are sieve tubes?
500
Epidermal cells just behind a root tip often produce THESE slender projections of the cell membrane. They greatly increase the root's surface area of a root and its ability to absorb water and mineral nutrients.
What are root hairs?
500
In leaves, ground tissue goes by THIS name. Its cells are packed with lovely green chloroplasts.
What is mesophyll?
500
Plants such as corn and sugar cane, which enjoy lots of direct sun, may be called by THIS name for their very unusual way of fixing carbon before the Calvin cycle. The first products of this process are 4-carbon compounds, instead of 3-carbon compounds.
What is C4?
