ANATOMY
Plants that grow year after year
What are PERENNIALS?
Plants are usually divided into these two basic groups.
What are VASCULAR and NONVASCULAR plants?
These are the two basic kinds of leaves.
What are SIMPLE and COMPOUND?
Stems come in a variety of forms. They can be woody or this.
What is HERBACEOUS?
These are the two basic root systems in plants.
What are FIBROUS and TAPROOT systems?
Plants that live for two years
What are BIENNIALS?
This group of nonvascular plants include mosses and liverworts.
What are BRYOPHYTES?
Alternate, opposite, and whorled are the three main types of this in creation.
What is LEAF MOSAIC?
The outermost layer of a woody stem is called this.
What is BARK?
This part of the root is composed of dead, thick-walled cells which protect the root as it penetrates deeper into the soil.
What is the ROOT CAP?
The parts of a plant that are NOT involved in reproduction
What are VEGETATIVE ORGANS?
A life cycle in which there is both a multicellular diploid and a multicellular haploid form
What is ALTERNATION OF GENERATIONS?
The term used to describe the edge of a leaf
What is LEAF MARGIN?
Monocot and dicot stems, though different both have these 'bundles' that contain xylem and phloem.
What are FIBROVASCULAR bundles?
In this region of the root, cells become fully differentiated, often producing root hairs.
What is the MATURATION region?
The plant tissue that contains undifferentiated cells
What is MERISTEMATIC tissue?
These seedless vascular plants belong to Phylum Pterophyta.
What are FERNS?
A monocot plant leaf's venation is usually this.
What is LINEAR?
New xylem and phloem are always produced in a woody stem by this.
What is the VASCULAR CAMBIUM?
In a cross-section of a root, this one-cell-thick layer guards the xylem and phloem, keeping out unwanted substances.
What is the ENDODERMIS?
Though not present in all plants, vascular tissue is comprised of these two types.
What are XYLEM and PHLOEM?
Cone-bearing trees or "conifers" belong to this phylum.
When days turn shorter, these cells' job is to block the leaf's supply of water and nutrients and then die.
What is the ABSCISSION LAYER?
This process removes a ring of inner and outer bark all the way around a tree trunk.
What is GIRDLING?
A root that contains little cortex tissue will have very limited ability to do this.
What is STORE subtances?
