Chapter 9 Flashcards
Deciduous
Plants that lose their leaves every year
Annual Ring
Layer of wood (secondary xylem) usually produced during one growing season.
What are guard cells?
Guard cells are cells surrounding each stoma. They help to regulate the rate of transpiration by opening and closing the stomata.
Axillary Bud
Bud located in the axil of a leaf
Intercalary meristem
intercalary (at internodes, or stem regions between the places at which leaves attach, and leaf bases, especially of certain monocotyledons—e.g., grasses)
Bulbs
a short stem with fleshy leaves or leaf bases
Internodes
A section or part between two nodes, as of a nerve or stem.
Bundle Scar
markings within a leaf scar at the location where vascular bundles were broken as the leaf petiole detached from the twig.
What is a leaf scar?
The mark left on a twig after a leaf falls
Collenchyma
A type of ground tissue that provides flexible support like the fibers in celery.
What is a leaf?
Typically a leaf is a thin, flattened organ borne above ground and specialized for photosynthesis, but many types of leaves are adapted in ways almost unrecognisable in those terms: some are not flat (for example many succulent leaves and conifers), some are not above ground (such as bulb scales), and some are without major photosynthetic function (consider for example cataphylls, spines, and cotyledons).
Cork Cambium
Lateral meristem that produces cork
Only found in woody plants
Cuticle
Waxy layer covering the epidermis of plants that protects the plant against water loss and disease causing organisms
Not present on the roots.
Eudicot
(5 characteristics)
Member of flowering plants called Eudicotyledones, It has…
two cotyledonsin the seed
Petal arrangements of 4 or 5
Netted leaf veins
Circular vascular bundles
Star-shaped vascular cylinders
Fibrouse root systems
Mass of similarly sized roots that cling to the soil
Flower
Reproductive organ of plants that contains the structures for the production of pollen grains and covered seeds
Fruit
Structure that forms from an ovary and associated tissues and encloses seeds
Ground Tissue
Tissue that constitutes most of the body of a plant
allow plants to growth their entire life.
Meristematic tissue
The tissue between the upper and lower epidermis of the leaf
Mesophyll
Association between roots and fungi. assit in water and mineral extraction
Mycorrhizas
One of many raised pores in the stem of woody plant that allow gas exchange between the atomosphere and plant tissues
Lenticels
Angiosperm plants having a single cotyledon in the seed
Monocot
What are Nodes?
The point on a stem where a leaf is attached or has been attached.
What is Parenchyma?
Parenchyma is one of the simple tissues in plants. It is the tissue that makes up most of the soft primary growth of roots, stems, leaves, and flowers. In anatomy, parenchyma means the bulk of the organ.
Is the pith in the middle of the stem true or false?
True.
What is the role of the Phloem?
Phloem takes the plant food from the leaves and takes it to other parts of the plant.
What is the definition of Primary Root?
The first root produced by a germinating seed, developing from the radicle of the embryo.
List one of the Reproductive organs for Plants.
