AP Biology Scavenger Hunt

Alex Tobias

Annelid

Definition: An annelid is any worm like organism of the phylum annelidia defined by their elongated and usually cylindrical bodies.

These worms are annelids because of

their worm like bodies and

segmented body parts.

Keratin

Definition: Keratin is a protein that makes up most of the structure of hair, nails, feathers, hooves, etc.

Gastropod

Definition: An animal phylum that contain any sort of mollusk, and have sensory organs on their head.

This hair contains the fibrous

protein, keratin.

This aquatic snail is a gastropod

because it's a type of mollusk.

Pioneer Species

Ectotherm

Definition: a pioneer species are a species that are the first to grow in a damaged or new environment.

Definition: An ectotherm is an organism that depends on external heat sources, like the sun, to regulate its body heat,

Moss is one of the first species

to grow in an environment.

Long-day Plant

This leopard gecko is an ectotherm because

it bathes itself in light like the sun or a

high wattage light bulb at a pet store, in order

to maintain a comfortable body heat.

Definition: A long-day plant is a type of plant that has to be exposed to light a certain amount of time in order to flower.

Littoral zone organism

Definition: a littoral zone organism is an animal that are commonly found on the shores of oceans, lakes, rivers, etc.

Carbohydrate

Arthropod

Spinach is a long day plant because it

has to be exposed to sunlight past a certain

critical point in order to obtain optimal growth.

Hermit crabs are commonly

found on littoral zones.

Definition: A carbohydrate is a macro molecule (large organic compound) that occur in foods like starches and sugars.

Deuterosome

Definition: an arthropod of the phylum Arthropoda, is an animal that is an invertebrate and has an exoskeleton, like crustaceans.

These crickets are invertebrates and have an exoskeleton.

Definition: A deuterosome is a super class/phylum of animals that are classified by their embryonic stages in which the first opening to develop is the anus.

Aggregate Fruit

A potato is a starch

Definition: An aggregate fruit is a type of fruit that consists of many little fruits contained to one receptacle.

This snake is a deuterosome because the

first opening to develop was its anus.

Calvin Cycle

Definition: the calvin cycle is a series of reactions in a plant where glucose is made from carbon dioxide.

Flower Ovary

A pineapple is an aggregate fruit because it's a

bunch of smaller fruits with their own ovaries in

the shape of one big fruit.

This is a plant, therefore it goes

through photosynthesis which involves

the calvin cycle.

Definition: a flower ovary is a the part of a flowering plant that holds the newly produced seeds (ovules).

Rhizome

Definition: a rhizome is a thick plant stem that grows horizontally underground and from it grow roots and shoots.

This flower's ovary is inside the

carpel towards the bottom.

Endosperm

Ginger root grows

horizontally underground,

and from it grow roots and shoots.

Definition: An endosperm is a part of a seed that contains a nutritive tissue that is a food store for the developing plant embryo.

Cellulose

Stomata

Definition: Cellulose is a polysaccharide that is a the main component in plant cells.

Gibberellins

Definition: Stomata are like the gates to a plant that regulate the flow of water, oxygen, and CO2 in and out of the plant.

Definition: a gibberellin is a plant hormone that regulates plant stem elongation, germination, and flowering.

This is a plant, so it has plant cells,

which are made mostly up of cellulose.

These popcorn seeds contain endosperm, it's

the white fluffy part that we see when we eat it,

just cooked and expanded.

Grapes contain this group

of growth hormones.

Frond

Animal with two chambered heart

Definition: A frond is a leaf or leaf like part of a plant usually large.

Definition: a two chambered heart pumps blood and nutrients all throughout the body; this is still a heart just another form of the heart that is in some animals.

These leaves like all other leaves have

stomata all over them to let water, oxygen,

and CO2 in and out of them.

Fish have two chambered hearts.

Pollen

This is a part of a fern that holds many fronds.

Definition: A powdery substance, usually yellow, that is released from the male part of plants and can be carried by pollen carriers to be recepted by female ovules in plants and become fertilized, basically like conception, sperm to egg.

Leaf Gymnosperm

Stem - Herbaceous vs. Woody

This flower still has the powdery

gamete on it's carpel

Female Pinecone

Definition: a herbaceous stem is fleshy and is flexible while woody stems are less flexible and are hard. Also herbaceous stems, at the end of the growing season, lower to ground level, while woody stems are persistent above ground level.

Definition: Leaf Gymnosperms are leaves that have their seeds out in the open and don't drop off their trees until after two or more growing seasons.

Definition: a female pine cone produces the seeds which are released when the pine cone opens up; they generally grow at the top of the tree as opposed to male pine cones which grow toward the bottom.

Angiosperm

These are woody stems and are not very flexible and stay above ground level throughout the year.

Definition: an angiosperm is a plant that has flowers and produces seeds within a space called the carpel.

This pine cone is female because it's latches

are open, indicating it's female.

These are herbaceous stems, very flexible, and lower to ground level at the end of the growing season.

Amniotic Egg

This is a flowering plant that produces

seeds in the carpel.

Definition: An amniotic egg is a shelled egg in which an embryo grows inside a fluid-filled sac (amniotic fluid).

These pine needles from a conifer

tree don't drop until after two seasons,

and their seeds are open to the environment.

Cambium

Tendril of a plant

Definition: Cambium is what forms a second vasular tissue located in

between the xylem and phloem of a plant, that helps in the transport of water throughout that plant.

This chicken egg is amniotic because it's shelled

and contains a developing chicken that is growing

inside an amniotic sac.

Definition: a tendril is a growing threadlike spiral that grows off of certain plants.

This tendril has grown off of a grape vine,

and is threadlike and spiraled.

Seen in this tree trunk on the outermost ring

is a layer of vascular cambium

Endotherm

Definition: An endotherm is an organism that can maintain it's body heat because of internal heat generation.

This dog is an endotherm because

it's a warm-blooded animal that can maintain

its body temperature through internal heat generation.

Deciduous Leaf

Define: A deciduous leaf is a type of leaf that falls off it's tree, shrub, bush, etc. according to the season.

This maple leaf is a

deciduous leaf because

it falls off the maple tree

in the fall.

Transpiration

Definition: The transport of water and other nutrients up through roots and shoots of plants

Water and other minerals are coursing

up through this tree trunk by transpiration

Meristem

Definition: An area of built of plant tissue around the tips and roots of plants which are slowly dividing into new cell tissue.

Right on the tips of these plants

there is plant tissue called the meristem

Pollinator

Definition: A pollinator is an organism that can carry pollen from one flower to another.

This bird can catch pollen on it's wings

and while flying pollen can detach and land

on other flowers, or other pollen

needing plants.

Exoskeleton

Definition: An exoskeleton is a protective hard covering on the outside of some organisms bodies.

This turtle has a hard protective

layer (exoskeleton) encasing his body

Eukaryote

Definition: A Eukaryote is an organism containing cells with DNA within a nucleus, eukaryotes include both plants and animals.

Radial Symmetry

This cat is an animal and contains

cells that have DNA within a nucleus

Definition: Radial symmetry is when an object/organism is symmetrical all the way around a central point.

Ethylene

This orange cut in half shows radial symmetry

because it's symmetrical all the way around the

center of the orange.

Cohesion of Water

Definition: Cohesion of Water is when water

sticks to nothing else but water.

Definition: Ethylene is a growth hormone in plants that promotes ripening of fruit, or breaking buds out of their slumber to begin growth.

This water may be frozen, but it's all water

connected together.

This crab apple tree bears crab

apples in the spring

and need the help of ethylene to

promote fruit ripening

Decomposition

Definition: Decomposition is the break down of material over time; rotting or decay.

Once these leaves fell from their tree,

unconnected from a life source, they began

to whither and rot

Adhesion of Water

Definition: Adhesion of Water is when water sticks to another surface other than water.

This image shows adhesion of water because

the water is sticking to the branches of this tree.
