Post #1 (plus please reference enzyme posted BEFORE I had any idea of what I was doing!)

Parasitism - see the little white fluffies sucking the life out of my mother's jasmine plant.
Parasitism is a type of non-mutual relationship where one organism benefits from the relationship and the other organism is harmed.

Connective tissue - aka Achilles tendon!
Connective tissue holds pieces of an organism together.

Lycopodium! Moss spores.
Spores are reproductive structures.

Living in symbiosis and Lichen it!
Lichen are composite organisms that consist of a symbiotic relationship between a fungus and a photosynthetic partner (plant).

 Bilateral symmetry of a Japanese painted fern
Bilateral symmetry is where one plane will divide an organism into rough mirror image halves.

Endotherm - my mom's hot hand.
 Endotherm is an organism that produces heat through internal means such as shivering or increasing metabolism.

Shiny cuticle layer of a hosta.
Cuticle layer of a plant is a non-cellular protective layer covering the outer cell layer.

Predation - see the shimmer of the spider's web above. Just waiting for a juicy fly to land...
 Predation is a biological interaction where a predator feeds on it's prey.

Animal with segmented body - our dog has a spine.

1st Biology Scavenger Hunt

Definitions from book.
(CHICKEN EGG) Amniotic egg: A shelled egg in which an embryo develops within a fluid-filled amniotic sac and is nourished by yolk. Produced by reptiles (including birds) and egg-laying mammals, it enables them to complete their life cycles on dry land.
(LILY) Anther: In an angiosperm, the terminal pollen sac of a stamen, where pollen grains containing sperm-producing male gametophytes form. Filament: In an angiosperm, the stalk portion of the stamen, the pollen-producing reproductive organ of a flower.
(ROMA TOMATO) Autotroph: An organism that obtains organic food molecules without eating other organisms or substances derived from other organisms. Autotrophs use energy from the sun or from the oxidation of inorganic substances to make organic molecules from inorganic ones.
(FERN) Spore: In the life cycle of a plant or alga undergoing alternation of generations, a haploid cell produced in the sporophyte by meiosis. A spore can divide by mitosis to develop into a multicellular haploid individual, the gametophyte, without fusing with another cell.
(CHESTER) Heterotroph: An organism that obtains organic food molecules by eating other organisms or substances derived from them.
(SOAPY HAND) Epithelial tissue: Sheets of tightly packed cells that line organs and body cavities as well as external surfaces.
