Family Relationships

Monocot Characteristics: Corn(Layla)

A flowering plant having one cotyledon or seed-leaf in the embryo
In monocot plants, the first shoot that emerges from the ground or from the seed is the epicotyl, from which the first shoots and leaves emerge.
The radicle aborts, and new roots arise
Have parallel leaf vine pattern
Vascular Tissue scattered
There is no main root
Pollen grain with one opening
Floral organs usually in multiples of three

Related Species: orchids, palms, and grain crops: maize, wheat, rice

Dicot Characteristics: Bean(Tommy)

Has two seed leaves (cotyledons)
In dicots, the hypocotyl is what appears to be the base stem under the spent withered cotyledons, and the shoot just above that is the epicotyl
Roots grow from the radical and apical meristem
Have netlike vein patterns
Vascular Tissue usually arranged in a ring
Taproot which is the main root is usually present
Pollen grain with three openings
Floral organs usually in multiples of four or five

Related Species: roses, peas, sunflowers and maples.

Stamen: The pollen-producing reproductive organ of a flower, consisting of an anther and a filament
Filament: The stalk portion of the stamen
Anther: the terminal pollen sac of a stamen, where pollen grains containing sperm-producing male gametophytes form
Carpel: The ovule-producing reproductive organ of a flower, consisting of the stigma, style, and ovary
Stigma: The sticky part of a flowers carpel, which receives pollen grains
Style: The stalk of a flowers carpel, with the ovary at the base and the stigma at the top
Ovary: The portion of a carpel in which the egg-containing ovules develop
Petal: A modified leaf of a flowering plant. Petals are the often colorful parts of the flower that advertise it to insects and other pollinators
Sepals: A modified leaf that helps enclose and protect a flower bud before it opens
Pollen: The fertilizing element of flowering plants, consisting of fine, powdery, yellowish grains or spores, sometimes in masses
Ovule: A structure that developes within the ovary of a seed plant that contains the female gametophyte
Double Fertilization: A mechanism of fertilization in angiosperms in which two sperm cells unite with two cells in the female gametophyte to form the zygote and endosperm

Steps of Reproduction:

the pollen lands on stigma,
the pollen tube grows to ovary,
the egg is fertilized,
the seed forms after fertilization,
then when the seed is ready, the seed is spreaded,
and then the seed lands somewhere and germinates and starts all over!

Life Cycle of Plants--Alternation of Generations

Alternation of Generations: A life cycle in which there is both a multicellular diploid form, the sporophyte, and a multicellular haploid form, the gametophyte.

Sporophyte: the multicellular diploid form that results from the union of gametes.The sporophyte produces haploid spores by meiosis that develop into gametes

Gametophyte: the multicellular haploid form that produces haploid gametes by mitosis. The haploid gametes unite and develop into sporophytes.

The gametophyte produces haploid gametes by mitosis, then two gametes unite and form a diploid zygote by fertilization. The zygote developes into a multicellular dipoloid sporophyte and then that sporophyte produces haploid spores by meiosis. Then the spores develop into multicellular haploid gametophytes.This cycle, from gametophyte to gametophyte, is the way in which all land plants and many algae undergo sexual reproduction.

Nutrient and Water Delivery/ Food Delivery

Nutrient and Water Delivery

I watered my babies about every 5 days or so. I wouldn't let them get too dry and i wouldn't let them get too wet.

Six Terms and Two RolesThat Have to do with Nutrient and Water Delivery:

Transpiration: The evaporated loss of water from a plant. During transpiration the water flows from the roots through the stem and out of the plant. So you must keep fresh water in your plants because it will evaporate.
Turgor Pressure: The force directed against a plant cell wall after the influx of water and swelling of the cell due to osmosis
Vascular Tissue: Plant tissue consisting of cells joined into tubes that transport water and nutrients throughout the plant body. This definitely helps the plant with nutrients and water delivery because it flows all throughout the plant.
Xylem: Vascular plant tissue that consisting mainly of tubular dead cells that conduct most of the water and minerals upward from the roots to the rest of the plant.It does this by the help of transpiration
Stomata: One of the tiny openings in the epidermis of a plant, through which gases and water vapor pass. Stomata permit the absorption of carbon dioxide necessary for photosynthesis from the air, as well as the removal of excess oxygen.
Guard Cells: The two cells that flank the stomatal pore and regulate the opening and closing of the pore. It knows when to let different air or water vapor out and when to save it.
How soil contributes to plant growth: Soil contributes to plant growth by nutriens within the soil, the pH balance, water and anchoring. The pH balance help germinate the seed. The soil helps absorb and provide water and nutrients. Also it helps to anchor the plants so they can grow healthy.
Role of The Casparian Strip: The casparian strip is a water- impermeable ring of wax in the endodermal cells of plants that blocks the passive flow of water and solutes into the stele by way of cell walls.

Food Delivery

Translocation: the conduction of soluble food material from one part of a plant to another.

Phloem: Vascular plant tissue consisting of living celles arranged into elongated tubes that transport sugar and other organic nutrients throughout the plant

Meristem: plant tissue that remains embryonic asa long as the plant lives, allowing for indeterminate growth
Primary Growth: growth produced by apical meristems, lengthening stems and roots

Secondary Growth: growth produced by lateralmeristems, thickening the shoots and roots of woody plants

Vascular Cambium: a cylinder of meristematic tissue in woody plants that adds layers of secondary vascular tissue called secondary xylem and secondary phloem

Cork Cambium: a cylinder of meristematic tissue in woody plants that replaces the epidermis with thicker, tougher cork cells

Hormones Involved:

Auxin: A term that primarily refers to indoleacetic acid, a natural plant hormone that has a variety of effects, including cell elongation, root formation, secondary growth, and fruit growth
Cytokinin: Any of a class of related plant hormones that retard aging and act in concert with auxin to stimulate cell division, influence the pathway of differentiation, and control apical dominance
ABA (Abscisic Acid): A plant hormone that slows growth, often antagonizing the actions of growth hormones. Two of its many effects are to promote seed dormancy ans facilitate drought tolerance
Gibberelin: Any of a class of related plant hormones that stimulate growth in the stem and leaves, trigger the germination of seeds and breaking of bud dormancy, and stimulate fruit development

Tropism: A growth response that results in the curvature of whole plant organs toward or away from stimuli due to differential tares of cell elongation

Young Plant Structure and Function

Root Hairs: A hairlike outgrowth of a plant root that absorbs water and minerals from the soil. Root hairs are tubular extentions of the epidermis that greatly increase the surface area of the root.
Node: a part of the stem that bears a leaf.
Internode: the part inbetween two nodes.
Primary Root: the first root produced by a germinating seed, developing from the radicle of the embryo.
Lateral Root: Roots that extend horizontaly from the primary root and serves as support to hold the plant securely in the soil.
Leaf: one of the expanded, green organs produced by the stem of a plant and any similar or corresponding lateral outgrowth of a stem. The main photosynthetic organ of vascular plants.
Tap Root: a main vertical root that develops from embryonic root and gives rise to lateral roots. Only in beans because the monocots do not have a main root.
Cuticle: A waxy covering on the surface of stems ans leaves that prevents desiccation in terrestrial plants
Dermal Tissue system: The outer protective covering of plants.
Cotyledon: A seed leaf of an angiosperm embryo. Some have one cotyledon some have two.
Coleoptile: the covering of the young shoot of the embryo
Bud: a small axillary or terminal protuberance on a plant, an undeveloped or rudimentary stem or branch of a plant.
Terminal Bud: dominant bud
