Liz's Scavenger Hunt

1) amniotic egg- An amniotic egg consists of a hard shell that helps prevent desiccation of the embryo, an amniotic fluid filled amnion that surrounds the embryo and provides it with a stable environment, and a yolk sac that nourishes the embryo throughout development. The Chicken Egg is an amniotic egg as the embryo resides within the shell during development and hatches once development is through.

2) cuticle layer of a plant- In botany, plant cuticles are protective, hydrophobic, waxy coverings produced by the epidermal cells of leaves, young shoots and all other aerial plant organs. Cuticles minimize water loss and effectively reduce pathogen entry due to their waxy secretion.

3) endotherm- Dogs are warm blooded, and they must generate their own heat to maintain their body temperature.

4) enzyme- Catalase is a common enzyme that speeds up a reaction which breaks down hydrogen peroxide into water and oxygen.

5) eubacteria- Eubacteria is the bacteria that causes tooth decay, food piosoning, and it is what makes milk into yogurt.

6) flower ovary - In the flowering plants, an ovary is a part of the female reproductive organ of the flower or gynoecium.

7) gymnosperm- Gymnosperm means as "naked seed". Gymnosperms are a taxonomic class that includes plants whose seeds are not enclosed in an ovule (like a pine cone).

8) redox reaction- A Redox Reaction is the transfer of electrons during the oxidation-reduction reactions involving loss of electrons in an oxidation reaction and gain of electrons in a reduction reaction between species is utilized for work that is useful. Candles use Redox Reaction through combustion, which is the burning of animal fat light to form lamps, torches, and candles.

9) territorial behavior- Territorial behavior refers to any sociographical area that an animal consistently defends. Mallory defends possession of her toy, and growls at Blazer (my other dog) to show her territorial behavior.

10) tropism- Tropism is the turning of all or part of an organism in a particular direction in response to an external stimulus. The plant grows higher in response to the external sunlight it absorbs.

11) negative feedback- As your body heats up over the normal temperature, it senses the increase so it releases more sweat to cool you. As the temperature cools down toward the normal temperature, the sweat glads quit releasing as much sweat. The temperature sensors are your nerves, the output are your sweat glands, and the negative feedback and other processing is in your brain.

12) coevolution- The term coevolution is used to describe cases where two species reciprocally affect each other’s evolution. Bees fly from flower to flower gathering nectar, which they make into food, benefiting the bees. When they land in a flower, the bees get some pollen on their hairy bodies, and when they land in the next flower, some of the pollen from the first one rubs off, pollinating the plant. This benefits the plants. In this mutualistic relationship, the bees get to eat, and the flowering plants get to reproduce.

13) aposematic coloring- a warning signal is associated with the unprofitability of a prey item to potential predators. This frog is brightly colored to warn off predators.

14) ectotherm- a lizzard is "cold blooded" and depends on external sources, such as sunlight or a heated rock surface, to regulate their body temperature

 

 

15) glycogen- Glycogen is a multibranched polysaccharides that serves as a form of energy storage in animals, such as this guinea pig. 

 

 

16) gibberellins- Gibberellins are plant hormones that regulate growth and influence various developmental processes. Grapes that come in contact with gibberellins will produce more grapes, and give them a bigger and better shape.

 

 

 



17) autotroph-  Mushrooms are autotrophs that are able to make energy-containing organic molecules from inorganic raw material by using basic energy sources such as sunlight.

18) artificial selection- the process by which humans breed other animals and plants for particular traits.Artificial selection has enabled the cultivation of new crops with desirable traits from one single common ancestor. From a mustard plant, humans use the flower buds and stem for broccoli, and the flower buds for cauliflower.

 

19) endosperm- The endosperm is the tissue produced inside the corn kernel around the time of fertilization. It surrounds the embryo and provides nutrition in the form of starch. This can make endosperm a source of nutrition in human diet.

 

 

 

 

20) exoskeleton- Lobsters have an external skeleton that supports and protects its body that is called an exoskeleton.

 

 

21) angiosperm- Angiosperms are a taxonomic class of plants in which the mature seed is surrounded by the ovule. In an apple the seeds in the middle are the angiosperms, and the apple surrounding the core is the ovule.





 

22) animal that has a segmented body- Spiders have two body segments. The front segment is called the Cephalothorax. The spider’s eyes, mouth fangs, stomach, brain and the glands that make the poison are on this part of the body. The legs are connected to this part, as well. The second part of the body is called the Abdomen. The back end of the abdomen is where the spinnerets, the silk producing glands, are.



 

 

 

 23) pollinator- Hummingbirds have long beaks and even longer tongues, which allows them to feed at flowers that are too long and thin for anything else. When a hummingbird inserts its beak into a flower to drink the nectar, sticky pollen grains cling to the side of its beak. When the hummingbird visits its next flower, some of the pollen grains are transferred, and if both flowers are the same species, pollination occurs.

 

24) ATP- a complex chemical compound formed with the energy released from food and stored in all cells, particularly muscles. Only from the energy released by the breakdown of this compound can the cells perform work.  Actively contracting muscles, for example running, obtain ATP from glucose stored in the blood stream and the breakdown of glycogen stored in the muscles. The result of muscle contraction produces ADP which when coupled with CP regenerates ATP.

 

 

25) mating behavior- Before mating, beetle males and females may engage in various forms of behavior. They may stridulate, or vibrate the objects they are on. In some species, the male climbs onto the dorsum of the female and strokes his antennae on her head, palps, and antennae. The male can also draw the antennae along his longitudinal vertex.



 

 

26) cellulose- Cellulose is a fibrous material of plant Origin and the basis of all natural and man-made cellulosic fibers. The natural cellulosic fibers include cotton, flax, hemp, jute, and ramie. The major man-made cellulosic fiber is rayon, a fiber produced by regeneration of dissolved forms of cellulose. Adding cellulose to food allows an increase in bulk and fiber content without a major impact on flavor.

27) heterotroph- A human is a heterotoph, they are consumers.
They cannot make energy from sunlight, so they need to consume other organisms to get the energy they need.  Humans obtain both energy and carbon from complex organic compounds.

28) decomposition- When a plant, animal, or insect dies, that plant, animal, or insect is broken into tiny pieces and those pieces become part of the soil (or in this case my ceiling). The process is essential for recycling the finite matter that occupies physical space in the biome.

29) C3 plant- Plants that survive solely on C₃ fixation (C₃ plants) tend to thrive in areas where sunlight intensity is moderate, temperatures are moderate, carbon dioxide concentrations are around 200 ppm or higher, and ground water is plentiful. C₃ plants lose 97% of the water taken up through their roots to transpiration, and rice is an example of this.

30) C4 plant- crab grass uses a supplementary method of CO₂ uptake which forms a 4-carbon molecule instead of the two 3-carbon molecules of the Calvin cycle. Hence it is considered a C₄ plant. (Plants that have only the Calvin cycle are thus C₃ plants.)
