Primary Growth
The region where cell division is actively occurring in a plant during primary growth.
What is the promeristem?
Produces cork towards the outside and cortex toward the inside.
What is the cork cambium?
The term for a seedless vascular plant that has only one spore type
What is homosporous?
Plants in this phylum have sporangia grouped in sori on the underside of leaves
What is Pteridophyta?
Modified roots that protrude out of the ground for aeration (typically found in plants in swamp-like regions)
What are pneumatophores?
The three primary meristematic tissues are protoderm, procambium, and THIS.
What is ground meristem?
Produces secondary phloem toward the outside and secondary xylem toward the inside.
What is the vascular cambium?
A modified stem that is flattened and leaf-like to engage in more photosynthesis
What is a cladophyll?
Genus of seed-free plants within Lycopodiophyta that is heterosporous.
What is Selaginella?
Bulbs, corms, and tubers are types of modified BLANK.
What is a modified shoot?
When fully matured, the protoderm becomes THIS.
What is the epidermis?
Small tears of the outermost bark that allow for gas exchange.
What are lenticels?
Cells found in monocot leaves that help reduce H20 loss through transpiration
What are bulliform cells?
Plants in this GENUS have sporangia protected by sporophylls on a strobilus.
What is Lycopodium?
Structures on a leaf that protect against herbivores and dessication and can be hair-like or spikey.
What are trichomes?
The primary xylem, primary phloem, and pericycle as a whole are referred to as THIS
What is the stele
The cork, cork cambium, and cortex together make up THIS.
What is the periderm?
Parallel leaf venation and a single cotyledon are common characteristics of this type of plant.
What are monocots?
Plants in this GENUS have sporangia protected by sporangiophores on a strobilus.
What is Equisetum?
An aboveground modified stem
What is a stolon?
Root apical meristems have THIS flow or pathway of water due to the casparian strip of the endodermis
What is the symplastic pathway of water?
You can count the rings of THIS to determine the age of a tree.
What is secondary xylem?
An indehiscent integumented megasporangium with 1 functioning megaspore
What is an ovule?
Structures on the spores of Equisetum that aid in spore dispersal
What are elaters?
An underground modified stem
What is a rhizome?
