 Long-Day Plant- Lettuce is a long-day plant because it needs 12 hours or more of sunlight in order to produce flowers.

Pollinators- Bees are pollinators because they eat on various flowers, picking up pollen that they carry on their bodies to other flowers. 

 Modified root of a plant- this Pothos plant has a modified root structure that stores water over time so you don't need to water it often. We only water the plant about once a week and it has lived 19 years.

Modified leaf- the furry catskins (also called pussywillows), are modified to grow before the rest of the leaves on the plant so that the wind can carry the seeds in the catskins away without the other leaves interfering. 

 Segmented Body- this ant, in the center of the photo on the concrete, has a segmented body with three parts.

 Rhizome- bamboo is a rhizome because its root is continually growing.

 Eukaryote- bread yeast is a eukaryote because the yeast cells have DNA stored in chromosomes inside a nucleus.

 Pollen- this weed gives off pollen for reproduction, and the clover below it also gives off pollen for reproduction. Pollen is a fine, yellow powder that contains the male genetic material.

 Seed Dispersal by Wind- This grain weed uses wind to disperse its seeds. The plant purposefully puts its seeds loosely on the end of the stem so the wind can carry the seeds away.

 Gametophyte- part of the two-part reproductive cycle of some plants and sporists, the lower leaves produce gametes, or asexual reproductive zygotes with one set of chromosomes.

Sporophytes- the tiny thin stems that come up out of the moss that take part in bisexual reproduction producing zygotes with two sets of chromosomes. 

 Modified Stem of a Plant- This rosebush has modified its stem to have thorns to protect the plant.

 Introduced Species: This is a Japanese Maple, an introduced species because it is not native to Washington, but was brought over from Japan.

 Lipids used for Energy Storage: This pepperoni contains lipids, or fat cells, that are stored in your body to be converted into energy.

 Autotroph- this dandelion is an autotroph because it uses photsynthesis to create its own food, and can be completely independent, not relying on any other species for survival.

 Cambium- although it is not visible, underneath the bark, between the bark and the "woody" sapwood and heartwood, lies the cambium, a layer of growth tissue.

 Auxin Producing Area of a Plant- the new leaves and shoots coming out of this weed produce the hormone auxin to extend their stems.

 Bilateral Symmetry: This leaf has bilateral symmetry because each side, left and right, is a mirror image of the other side.

 Phloem- This dogwood tree contains phloem, a tissue that carries sugar and energy down from the leaves of the plant to the roots.

Gibberellins- a plant hormone used to jumpstart flowering, stem growth and reproduction. Gibberellins is used to stimulate this flower to grow.
