Term
Photosynthesis generally occurs in this type of cell...
Definition
Parenchyma
Term
The five types of Plant cells are ...
Definition
Parenchyma, Collenchyma, Sclerenchyma, Xylem Cells, Phloem Cells
Term
These structures elongate the plant at vertically
Definition
Apical Meristems
Term
These structures grow the plant horizontally from the inside
Definition
Lateral meristems
Term
Expands the tree laterally by adding a secondary layer of xylem to its inside and a secondary layer of phloem to its outside
Definition
Vascular Cambium
Term
Coats the tree with a new layer of epidermis when the tree expands
Definition
Cork Cambium
Term
Ground Tissue that is internal to the vascular system is called ...
Definition
Pith
Term
Ground tissue that is external to the vascular tissue is called ...
Definition
Cortex
Term
Forms protective layer around vascular tissue and is the the innermost border of the cortex
Definition
Endordermis
Term
The three types of tissue systems in plants are ...
Definition
Dermal, vascular, and ground tissue system
Term
Trichomes are ...
Definition
hairlike growths that extend from the shoot epidermis
Term
Plasticity in plants refers to ...
Definition
their ability to alter themselves in response to their environment.
Term
The three basic organs of plants are ...
Definition
roots, stems, and leaves
Term
The terminal bud is composed of ______ meristems
Definition
apical
Term
If terminal buds are physically close to the axillary buds, the axillary buds will not grow due to a phenomenon known as ...
Definition
Apical dominance
Term
The main photosynthetic organs of vascular plants are...
Definition
leaves
Term
In woody plants, what replaces the epidermis to form a stronger coating?
Definition
Periderm
Term
The two vascular tissues are known as...
Definition
Xylem and Phloem
Term
The function of the xylem is...
Definition
... to conduct water and dissolved minerals from the root up into the shoot; it's a one-way system.
Term
The function of the phloem is...
Definition
... to transport organic nutrients that are made in the leaves to wherever they are needed.
Term
If you are eating a stick of celery, you are likely to be consuming the most of which plant cell type?
Definition
Collenchyma; solid yet "malleable".
Term
Which type of plant cells, dead at functional maturity, transport water?
Definition
Xylem cells
Term
These cells lack organelles in order to increase nutrient-transport efficiency...
Definition
Phloem cells
Term
The bark of a tree is most likely made of mostly what kind of cell?
Definition
Schlerenchyma
Term
What two types of plant cells are dead at functional maturity?
Definition
Sclerenchyma and Xylem-cells
Term
These structures from branches and widen the plant from the outside...
Definition
Axillary buds
Term
The three zones of cells in which root cells grow are...
Definition
zone of cell division, elongation, and maturation
Term
Stomata are...
Definition
microscopic pores on leaves and stems that allow for gas an water exchange between a plant and it environment.
Term
Sieve tube cells are _______. They are specialized for phloem/xylem?
Definition
The sieve tube is an elongated rank of individual cells, called sieve-tube members, arranged end to end. These cells are specialized for phloem transport.
Term
These are elongated cells that serve to transport water and mineral salts in vascular plants
Definition
Tracheids.
Term
How does the pruning of trees make them grow more bushy?
Definition
Pruning eliminates apical meristems as such eliminates their dominance in getting resources so most of the resources will go to growth in axillary bud.
