Dried fruits become dry when mature

All angiosperms are under what phylum?

Anthophyta

The haploid male microgametophyte is formed where?

The anthers

The haploid female megagametophyte is formed where?

The pistil

Double fertilization

One of the sperm nuclei fertilizes the egg to form a zygote. The second sperm nucleus fuses with the embryo sac which creates a 3n nucleus and eventually gives rise to the endowed (nutritious tissue in ovule)

What happens after double fertilization?

1) zygote develops into tint sporophyte embryo


2) rest of the ovule develops into a seed


3) surrounding ovary and tissues develop into fruit

Male and female reproductive parts evolved from what?

Sporophylles (spore bearing leaves)

Pedicle

The stalk that attaches the flower to the stem

Receptacle

The large region at the tip of the pedicle where the flower arises

Inflorescence

Cluster of pedicles

Septals

The part that enclose and protect flower buds

Calyx

All septals of a flower collectively

Petals

Visual attractants for pollinators

Corolla

All petals of a flower collectively

Stamens

Malet reproductice organs (anthers and filaments)

Filament

Stalk like structure of the stamen

Anther

Contain pollen sacs of stamen

Carpel

Female reproductive organ (style, stigma, ovary)

Stigma

Receives pollen

Style

Where pollen grains produce a pollen tube that extends down to the ovary

Monocot

Number of petals, septals, and stamina occur in threes or multiples of threes

Dicot

The floral parts occur in fours or fives

Perfect flower

A flower with both stamens and pistol but calyx and corollary may be absent (only presence of both sexes)

Imperfect flower

A flower that lacks either stamens or pistil

Stamintate flower

An imperfect flower that has only stamens

Pistillate flower

An imperfect flower thats has pistils only

Complete flower

A flower that possesses septals, petals, stamens, and pistil

Incomplete flower

A flower that lacks one or more of the four organs types (septals, petals, stamens, pistil)

Dioescious

The sexes are separate

Monoecious

Both sexes are on the same plant

What two terms deceive floral symmetry?

Radial symmetry and bilateral symmetry

Hypogynous flower

The ovary is superior

Epigynous flower

The ovary is inferious

What are in the plant family poaceae?

Grasses (wheat, oats, rye, barley, rice)

Asteraceae

1) dicot


2) inflorescnese of many mini flowers that form a floral head


3) disk flowers or ray flowers

Poaceae

1) monocots


2) inflorescence


3) wind pollinated

What produces the pollen tube?

The vegetative cell of the pollen grain

Fruit

Mature ovary or ovaries of an angiosperm

Zea leaf monocot (parallel venation)

Coleus stem tip

Zea stem monocot

Ligustrum leaf dicot (pinnate)

Onion root tip

Ranunculus mature root

Syringa leaf dicot

Coleus stem

Ginger with Rhizome stem to specialize in storage and vegetative reproduction

Potato with Tuber stem to serve as primary storage organ

Bulb

Corm with short thick stems to serve as storage function

Leaf structure

whorled

Leaf structure

Opposite

Stolon stem which serve as vegetative reproduction

Leaf structure

Alternate

Lemon grass monocot parallel

Specialized stems

What type of venation

palmate

Doubly compound

What type of venation

Pinnate

What type of venation

Pinnate

Key characteristics of flowering plants

1) flower


2) reproductive structures


3) pollination


4) double fertilization

Chart

Pistil

1 or more carpels

Monocots

1) one seed leaf


2) parallel leaf veins


3) floral parts in multiples of three


4) usually herbaceous (non-woody)


5) roots are fibrous


6) stem vascualr arrangement is scattered

Endicott (dicots)

1) 2 cotyledons


2) leaf veneration pinnate or palmate


3) reproductive floral parts in fours or fives


4) usually woody


5) one main tap root


6) stem vascualr arrangement is in a ring

Chart

What are the simple tissues?

1)Epidermis


2) meristem


3) cambium


4) parenchyma


5) collenchyma


6) sclerenchyma

Epidermis

Thin layer of cells that cover primary tissues. Cutin forms protective layer of cuticle

Meristem

1) Region of active cell division. Found in terminal buds and axillary buds.


2) apical meristems are primary growth (grow up)


3) lateral meristems (Cambrium) are secondary growth (grow horizontal)


¤ cork cambrium are found beneath outer surface and produce cells that become bark


¤ vascualr cambrium has two vascular tissues xylem and phloem

Parenchyma

Thin walled large cells with vacuoles for storage. Become important for young plants but not so much for mature plants

Collenchyma

Thick walled cell for structure support and can still bend petioles (stalk like portion of a leaf that attaches the leaf to the plant)

Sclerenchyma

Similar to collenchyma but provides greater support

What are the three general patterns of leaves?

Alternate, whorled, opposite

Xylem

1 ( Nonliving cells of tracheids and vessel elements which transport water and mineral from the roots to the leaves


2) may contain parenchyma and fibers

Phloem

1)Use living cells of sieve tube elements to transport sugars around


2) may contain companion cells, parenchyma, and fibers

What are the complex tissues?

1) Xylem


2) phloem


3) cortex

Cortex

1) Not a vascualr tissue but acts as filler tissue for structure and support


2) contain combo of parenchyma, collenchyma, sclerenchyma

What type of leaf venation

Palmate: all leaflets emanating from a common point

What type of leaf venation
