Roots
Roots create these to increase their surface area for water and mineral absorption
This is a point in a stem where leaves and axillary buds are located.
What is a node?
When a plant is rigid and full of water, we call it this.
What is turgid?
This ground tissue is the most common, found in cortex and pith
What is Parenchyma?
This is the name of the bacteria that infects legume plants to help it produce nitrogen from the atmosphere.
What is Rhizobium bacteria?
This cluster of cells is found at the tip of the root for protection, secreting mucigel to lubricate the pathway for root growth.
What is the root cap?
This type of stem coils around objects, decreasing the plant's need to create added structure for the plant's growth.
What is a tendril?
A high water year yields what kinds of cells?
larger or elongated
This ground tissue has thickened cell walls that are not lignified, and rely on turgidity for their support.
What is collenchyma?
This enzyme can work using ATP to produce dinitrogen to amonium, but ceases to work when in contact with this element.
What is oxygen?
This zone is where root growth occurs, and is just a couple millimeters above the root tip.
What is the zone of elongation?
This type of stem is underground and allows the plant to produce asexually, protects the plant from freezing in cold weather, and stores starches.
What is a rhizome?
Plants increase their solute content by using this type of transportation across the cell membrane.
What is active transport?
This ground tissue has many uses; it contains mesophyll cells and also can hold starches/reserves for the plant.
What is parenchyma?
As a symbiotic relationship, the plant receives nitrogenase from the rhizobium to convert Nitrogen, and in return the rhizobium receives this from the plant.
What is sucrose?
This is the first layer of cells found in the stele where lateral roots are formed.
What is the pericarp?
This cell often is found in all vasuclar plants, and in angiosperms it is a tube-like structure that has a companion cell that contains its nucleus.
What is phloem?
This is caused by a higher solute content and lower pressure in the plant.
What is plant water uptake and movement?
Name an example of a plant that contains sclerids.
Pear
This enzyme is synthesized by the rhizobium bacteria to convert N2 to NH3.
What is nitrogenase?
This is a ring around the endodermis, the last layer of cells in the cortex, that stops water from moving through the apoplast and forces it enter the symplast.
This happens early in the mornings and during the night, when water continues to be taken in by the plant caused by mineral salt uptake the day before, causing the pressure through the roots, stems and leaves to be relieved at the tip of a plant (often grasses).
What is guttation?
The function of these cells is to protect the leaves from water loss by curling the leaf with it reaches wilting point.
What are bulliform cells?
There are two types of these cells: fibers and sclerids, which are both lignified and provide structure and support for the plants.
What is Sclerenchyma tissue?
In root nodules in legume plants, oxygen is bound to this carrier to the mitochondria, giving the nodule a pinkish appearance.
What is leghemoglobin?
