Q

Lichens

A

symbiotic organsisms
asscociations of fungi and either green or cyanobacteria
live on trees, soil, ricks and manmade structures
provide protection for the photosynthetic organism and a structure support for gas exchange, secretes compimds that aid mineral absorption an provides protection from herbivores
mutualistic association
neither symbiont could survive alone

22
Q

Double fertilization

A

One sperm fuses with the egg to form a 2n zygote
The other sperm nucleus fuses with 2 polr nuclei to form a polyploidy (3n or 5n) endosperm
Endosperm provides energy to the developing embryo

23
Q

Monocots

A

Grasses, lilies, orchids, palms looks like monkeys

leaves with parallel veins

24
Q

Dicot

A

Oaks, Bean, spinach, rose

25
Q

Plant Tissues

A
Vascular Tissues
Dermal Tissue (prevents injury and water loss)
26
Q

Plant Organs and Functions

A

Roots
Stems
Leaves
Flowers

27
Q

Roots

A

anchor plant
absorb/transport water and minerals
store

28
Q

Stems

A

transport water and nutrients

support leaves and flowers store

29
Q

Leaves

A

gas exchange

Photosynthesis

30
Q

Flowers

A

attract pollinators by scent and color

reproduction

31
Q

Two types of Roots

A

Fibrous Root Systems

Tap Root System

32
Q

Fibrous Root Systems

A

similar primary and secondary roots

33
Q

Tap Root System

A

large primary root and small secondary roots

34
Q

Shoots

A

Apical Meristem- mass of dividing cells at the tip of shoot
Leaf Primordia- bulgs that flank the meristem
Node- point on the stem where the leaf is attached
Axillary Bud- a lateral bud

35
Q

Eudicot Stem

A

Ring

leaves with netted or reticulate veins

36
Q

Leaves

A

major light-capturing organs of most plants

37
Q

Veins

A

(xylem and phloem) run through leaves

38
Q

Dermal Tissue

A

Mostly epidermal cells - upper and lower epidermis

Stomata

39
Q

Stomata

A

Gas exchange
Humidity regulates opening and closing
Guard cells
Found mostly on the underside of the leaf

40
Q

Flower

A
Be able to able flower parts:
Ovule
Ovary 
Stigma 
Style 
Filament 
Connective 
Anther 
Microsporangium 
Stamen
Floral axis 
Articulation
Pedicel 
Nectary
41
Q

Fruit and Seed Dispersal

A

A fruit is a mature ovary
a seed is a mature ovule
Fruits often aid in the dispersal of their seeds

42
Q

Four main morphological and developmental features

A
  1. Type of body symmetry
  2. Presence or absence of different tissue types (and organ if present)
  3. Presence or absence of a true body cavity (Coelom)
  4. Patterns of embryonic development
43
Q

Types of symmetry

A

Asymmetrical
Radial
Bilateral

44
Q

Asymmetrical

A

without symmetry
irregularly shaped
ex: sponges

45
Q

Radial

A

parts radiate from the center like spokes on a wheel
no left or right sides
if cut

46
Q

Bilateral

A

has a left and a right side

if you cut down the center two pieces are mirror images of each other

47
Q
