Cards

Term
Relationship b/w
Coral & Algae
Definition
Mutualistic
-80% food algae make are eaten by the coral, surrounding and attached to the algae
-Coral grow in good shape to catch light by algae
-Coral provides carbon source for algae
Term
Relationship b/w
Jelly Fish & Algae
Definition
Mutualistic
-Jelly fish w/o stingers have area where algae live
-Seek out and stay in sun so algae can make nutrients
-Jelly swims down to deep decomposing stuff so algae can get carbon source
Term
Relationship b/w
Ants & Plants
Definition
-Ants protect plants from predators eating them (bite hurts)
-Ants chew rival plants to death
-Ants rewarded with: Home in the plant, Nectar, Protein packets to feed to larvae
-Plants eat ant poop
Term
Relationship b/w
Fungi & Tree
Definition
Mutualistic
-Fungi digest wood, Rot tree to the core leaving it hollow (eats dead tissue only)
-Hollow tree continues to grow b/c tree only needs outer layer
-Hollow is beneficial b/c protects against storms
-Roots and animals can live in the hollow tree, Tree eats animal poop
Term
Relationship b/w
Fungi & Orchids
Definition
-Fungi wrap around orchid roots
-Fungi supplies needed nutrients to orchid seed
-Fungi surface area helps plants grow by getting more nutrients
Term
What is a Lichen?
What is role of each organism?
Definition
Fungi + Lichen
-Intimate relationship
-Hard skins -Curly crust -Bushes
Lichens flourish in harsh environments like desert, and on tombstones
-Fungi deliver moisture to algae by absorbing fog
-Slow growth
Term
Relationship b/w
Mistletoe & Tree
Definition
Parasidic
-Mistletoe has no roots, absorbs all moisture from tree
-Makes some food by flowering, leaves
Ex: Christmas tree: Entire tree grows by attaching to roots of other plants and sucking out the moisture to live, Make some of own food with leaves
Term
Relationship b/w
Mistletoe & Birds
Definition
-Eat fruit seed coating off the mistletoe
-Poops out sticky seed and wipes it off (dance) onto the tree branch
→Seed attaches to branch and absorbs nutrients to grow
Term
Relationship b/w
Dotter & Nettle
Definition
Parasitic
-Dotter needs nettle to live
-Siphons moisture from nettle growths that dotter needs to flower
Term
Raflezia
Definition
Parasitic
-Largest flower in the world
-Only flowers (no roots)
-Lives off roots of others
-Attracts flies for germination with rotting meat smell
-Cup: Houses spiky disc: Under disc is liquid pollen
-Fly picks up pollen and carries it to other Raflezia
-Grows so big b/c steals food and doesn’t use energy to make its own (Puts all energy into growing big)
Term
Adaptations plants growing in Arctic Tundra use to survive
Definition
Need: Water, Nutrients, Warmth/Light
-Live in rock (algae)
-Grow slowly, need only minimal sunlight (lichens on rocks)
-Tiny flowers grow close to the ground, away from wind during summer when water melts
-Plants absorb dead animals as decay = food
-Track sun, pointing towards it (Poppies)
Term
Snowbells
Definition
Alps
-Bugs grow during autumn, remain dormant until sun
-Buds open before snow melts (in anticipation of sun)
-Vegetation decays slowly
Term
Plant adaptations on
high mountains use to survive cold
Definition
Grow in cushion round humps
-Conserve heat, reduce wind chill
-Absorbs heat, photosynthesizing and growing
Grow to same height
-Not block one another from sun
Hair keeps plant warm
-Large, extensive root system absorbs nutrients from soil
-Vlunerable buds protected by harsh conditions by leaf covering

Ex:Mt. Kenya Moss: Freezing at night causes moss to be uprooted, Moss forms balls that roll around on frozen land until day melts harsh conditions
Term
Plant adaptations in
Desert
Definition
Moisture scarce in hot, dry
-Store water in bloated branches
-Condense life into few weeks (no underground storage) and make seeds that lay dormant until rains
-Pretty flowers grow to attract pollination
Ex: Quiver Tree: White color reflects sun away, Pores minimalize water loss, Smooth trunk relatively impermeable, Reduces loss of water vapor by self-amputation of branch (get by on having fewer leaves)

Ex: Window Plant: Transparent tops catch sun for photosynthesis, Get covered by sand but live underground so hold nutrients, Underground to protect from predators

Ex: Mole rats bring plant bulbs underground to eat, but forget and the bulbs sprout

Ex: Cactus: Water kept in grooves, Tufts of flowers on crowns of branches, Catch liquid before evaporate, Defend against predator w/ spines
Term
Plant adaptations in
Low nutrient soils
Definition
Rain washes away nutrients
-Plants eat animals!

Ex: Bromilia grows into water, Vacuum bladder traps animal

Ex: Sticky drops on hair look sweet, Sticky, Insect caught and folded into plant

Ex: Amazon Water Lilly: Leaves protected by spines, Float with air girder, Turned up edges push competition away
Flower: Day 1 OPENS: Smell attracts beetle
Night 1 CLOSES: Traps beetle, covered in pollen
Day 2 OPENS: Lets beetle go, others come and pollinate lily
Day 2 NIGHT: Closes and dies so cannot get self polinated
Term
Similarities b/w
Plantae & Green Algae
Definition
-Pigments Chlorophyll a and Chlorophyll b
-Accessory pigments carotenes (lipids) and Xanthphylls
-Store excess products of photosynthesis as starches
-Cell wall of cellulose
-Replication mechanism is cell plate formed by vesicles
Term
Features of
Bryophytes
Definition
Mosses
Vascular Tissue-Non-vascular
Dispersal/Reproduction-Spores
Desiccation Prevention-Cuticle
Gas Exchange-Stomata + Guard cells
Gametangia-Archegonium+Antheridium / Sporangium
Lignin-Grow kinda tall
-Gametophyte Dom
Term
Pterophytes
Definition
Fern
Vascular Xylem+Phloem
Spores
Cuticle
Stomata+Guard Cell
Archegonium +
Antheridium / Sporangium
Lignin makes it grow kinda tall
Sporophyte Dom
Term
Gymnosperms
Definition
Trees
Vascular Xylem+Phloem
Seeds: Naked
Cuticle
Stomata+Guard Cells
Archegonium+Antheridium / Sporangium
Lignin grows HUGE TREE
Sporophyte Dom
Term
Angiosperms
Definition
Flowering plants, Grass (only flowers)
Vascular Xylem+Phloem
Seeds:Covered
Cuticle
Archegonium+Antheridium / Sporangium
Sporophyte Dom
Term
Vascular Tissue
Definition
Used to carry nutrients throughout the plant
Term
Xylem
Definition
Vascular Tissue
Water flows up into the leaves where it evaporates
Term
Phloem
Definition
Vascular Tissue
"Flows" down, Carries waste products out plant
Term
Dispersal/Reproductive Mechanism
Definition
Spores or Seeds
Naked Seed: No additional tissue around their seeds
Covered Seed: Fruit flesh -Entices animal toe eat the fruit and poop out the seed, dispersing them
Term
Desiccation Prevention
Definition
Stop loss of water through evaporation
-Cuticle: Waxy covering stopping loss of water vapor
-Algae don't have cuticle b/c live in water
Term
Gas Exchange
Definition
Stomata: Holes allowing for gas exchange inside leaves of plants, But still leads to water loss

Guard cells: 2 surround each stomata, Protect and limit water loss
-U shape = Open, Exchange in good condition
-Flaccid = Cover stomata, stopping water loss
Term
Archegonium
Definition
Gametangia
Protect Egg
Term
Antheroridium
Definition
Gametangia
Protect sperm
Term
Lignin
Definition
Polymer found in xylem/phloem
Provides plant support, allowing them to overcome the effects of gravity (grow tall)
-Gymnosperms and Angiosperms grow tall with this
