Q

Mutalistic Relationship Between Fungi and Plants

A

Ectomycorrhiza
Endomycorrhiza
Lichens: fungus & photosynthetic organism -support each other sm one wouldn’t survive without the other
Mycelia obtain nutrients, plants fuel metabolism

17
Q

Major Groups of Plant Kingdom and Characteristics

A

Draw this out

18
Q

Bryophytes and major phyla of them

A
Nonvascular Seedless Plants 
Lack tracheids
Require water for reproduction
Spends most of lifetime in haploid state!!! Gametophyte is huge, sporophytes are dependent and small
Liverhorts, Hornworts, Mosses
19
Q

4 Gymnosperm groups and Characteristics of Each

A

Coniferophyta: most diverse, pines, cedars etc.
Cyadophyta: have largest sperm cells, palm tree
Gnetophyta: only w vessels in xylem, WEG
Ginkgophyta: flagellated sperm, dioecious

20
Q

Xylem vs Phloem

A

Xylem: water, thicker, and dead cells
Phoelm: sugar, thinner, and living cells

21
Q

Monoecious vs Dioecious

A

Mono: both Male and Female on one strand
Dio: separate plants w organs

22
Q

Different pollination Types and Pollinator examples

A

Bees, wind etc

23
Q

Asexual Reproduction in Plants

A

Anthers

24
Q

6 qualities of Life

A
Grow 
Reproduce
Actively maintain homeostasis 
Acquire/Use Energy
Sense and respond to stimuli
Evolve
25
Q

Shoot system

A

Above ground
Reproductive parts: flowers/fruits
Vegetative part: leaves/stems

26
Q

Root system

A

Usually underground
Supports plant
Absorbs water and minerals from soil

27
Q

Meristematic tissue

A

Regions of continuous cell division and growth

Two types: apical and lateral

28
Q

Non-meristematic tissue

A

Cell regions that are not diving anymore

Permanent tissue

29
Q

3 Types of Permanent Tissue

A

Dermal: covers and protects plant
Vascular: transports water, sugar, minerals
Ground: provides support to other tissues

30
Q

Stems

A

Provide support to plant and sometimes food

MODIFICATIONS: stolons, onion bottom

31
Q

Roots

A

Anchors plant in place, Absorbs minerals and water, Stores carbs
Primary root is first to emerge, lateral roots branch off to side
Root hairs: increase surface absorption
MODIFICATIONS: carrots, onion hair things at end

32
Q

Leaves

A
Main site of photosynthesis 
Simple and compound
Parallel, net-like and venation
Vasc tissue: xylem & phloem
MODIFICATIONS: Venus fly trap, onions outside
33
Q

Stomata

A

Regulation of gas exchange

34
Q

Water potential

A

Measure of potential energy in water
Influenced by solute conc, pressure and gravity
LOWER outside than inside cell means water moves OUT of cells plant wilts
HIGHER outside than inside cell means water moves INTO cells and plant is turgid

35
Q

Aquaporins

A

Transport proteins that facilitate passage of water through membranes

36
Q

Sources vs sinks

A

Sources: structures producing sugars
ex. Leaves
Sinks: where the sugar is delivered
Ex. Seeds, roots, bulbs etc

37
Q

Responses to Light

A

Phototropism: towards light
Negative gravitropism: shoot apical tip upward
Positive gravitropism: roots pulled downward
Thigmotropism: touch
