Katie's Scavenger Hunt

 

Pollen: Pollen the fertilizing element of flowering plants. It is a fine, powdery, yellowish substance produced by the anthers of plants. Pollen consists of numerous fine grains containing the male gametes that can fertilize the female ovules. Pollen is transferred from the anther of one plant to the pistil of another plant by wind, insects or other animals. The pistil is the female organ of a flower, including the stigma, style, and ovary. The flowers in this picture contain pollen.

 

Pollinator: A pollinator is the agent that moves pollen from one plant to another. A pollinator could include an insect or a bird. In this picture the bee is the pollinator.

Heterotroph: A heterotroph is an organism that is unable to obtain carbon from carbon dioxide. Heterotrophs obtain carbon by feeding on the organic material present in other organisms, living or dead. My dog is a heterotroph because she survives by eating her dog food.

 

Adaptation of an animal: For animals an adaptation is the idea that an animal had developed features to help them survive in their environment. My dog is an Australian Shepherd and he has a water-resistant coat that the breed developed to stay comfortable in rain and snow. Also, Australian Shepherds in cold climates have a heavier undercoat than those who live in sunnier areas.

 

Amniotic egg: Amniotic eggs contain a yolk to nourish the developing organism. The shell helps prevent drying, and inside the egg are a series of fluid-filled membranes which allow the embryo to survive. This kind of egg is unique to the amniotes, including turtles, lizards, birds and other animals. The chicken egg is an example of an amniotic egg.

 

Ectotherm: An ectotherm is an animal such as a reptile (not including birds), fish, or amphibian, that must use environmental energy and behavioral adaptations to regulate its body temperature. This snake is an ectotherm because it is a reptile.

 

Endotherm: An endotherm is an animal, such as a bird or a mammal, that uses metabolic heat to regulate body temperature. This rabbit is an endotherm because it is a mammal.

Lichen: Lichen is formed by the mutualistic association between a fungus and a photosynthetic alga or cyanobacterium. This tree is covered in lichen.

Autotroph: An autotroph is an organism that obtains organic food molecules without eating other organisms or substances from other organisms. Autotrophs use sun energy or energy from the oxidation of inorganic substances to make organic molecules from inorganic ones. This flower is an autotroph because it obtains its food using sunlight in the process of photosynthesis.

Bilateral Symmetry: Bilateral symmetry is a characterization of the body form where the body is divided into two equal but opposite halfs along a central longitudinal plane. This dragonfly has bilateral symmetry because if you were to divide it in half, the halves would be equal but opposite.

Angiosperm: An angiosperm is a flowering plant that forms seeds inside a protective chamber called the ovary. An angiosperma plant that produces seeds within an enclosure; they are fruiting plants, although more commonly referred to as flowering plants. This plant is an angiosperm because it bears fruit which contain seeds.

Gymnosperm: A gymnosperm is a vascular plant that bears naked seeds (seeds that are not enclosed in specialized chambers). This pinecone is a gymnosperm.

Stigma and Style of Carpel: A style is the stalk of a flower’s carpel, with the ovary at the base and the stigma at the top. The stigma receives pollen at pollination and it is on the stigma that the pollen grain germinates. This flower contains a style and a stigma.

Chitin: Chitin is a structural polysaccharide of an amino acid sugar.  It is a tough, protective, semitransparent substance that acts as the main component of arthropod exoskeletons and the cell walls of some fungi. This insect has chitin in its exoskeleton.

Cuticle Layer of a Plant: The cuticle layer of a plant is a waxy covering on the surface of stems and leaves. This layer prevents desiccation and protects the plant from UV radiation and different kinds of physical, chemical and biological agents. The cuticle layer also provides some support to the plant.

Tropism: A tropism is a growth response that results in the curving of plant organs toward or away from stimuli owing to differential rates of cell elongation. This plant has become a tropism from bending toward sunlight.

Hydrophobic: When something is hydrophobic it has an aversion to water. It tends to coalesce and from droplets in water. Oil is hydrophobic because it does not mix with water.

Anther and Filament of Stamen: The stamen is the pollen-producing reproductive organ of a flower, consisting of an anther and a filament. The filament is the stalk of the stamen. The anther is the pollen-bearing part of the stamen. This flower contains an anther and a filament.

Animal that has a Segmented Body: Segmentation is the division of a body part into segments. It can be homomeric segmentation in which the segments are more or less the same, or heteromeric segmentation where the segments vary from one another. Arthropods have segmented bodies. This dragonfly is an example of an animal with a segmented body.

Flower Ovary: The flower ovary is a part of the female reproductive organ. It is part of the pistil, which contains the stigma, the style and the ovary. This flower contains an ovary which holds the egg-containing ovules.

Exoskeleton: The exoskeleton is the external skeleton that supports and protects an animal's body. Examples of exoskeleton animals include various types of insects, crustaceans such as crabs and lobsters, and various groups of shelled mollusks, including snails and clams. This lobster has an exoskeleton.

Eukaryote: Eukaryotes include animals, plants, protists and fungi. These organisms are composed of one or more cells. These cells each contain a clearly defined nucleus enclosed by a membrane, along with membrane-bound organelles that perform specific functions. This ladybug is a eukaryote because it belongs to the animal kingdom.

Territorial Behavior: Territorial behavior is a behavior in which an animal defends a bounded physical space against encroachment by other individuals. This may involve direct aggression or indirect mechanisms, such as scent marking or singing. My dog displays territorial behavior when she is eating her treats and someone comes near her by growling and covering the treat.

 

Detritovore: A detritovore is an organism that feeds on and breaks down dead plant or animal matter, returning essential nutrients to the ecosystem. Detritivores include bacteria and protists as well as larger organisms such as fungi, insects, and worms. This worm is a detritovore.

Modified Leaf of a Plant: This is a modified leaf of a plant, adapted to suit its environmental needs and to increase its chances of survival. This leaf has spines on it for protection.

Modified Stem of a Plant: This is a modified stem of a plant, adapted to better suit the plant's needs and increase its chances of survival in its environment. This stem has thorns on it for protection.

Xylem: Xylem is one of the two types of transport tissue in  plants. It is located in stems, leaves and roots. The most common xylem tissue is wood, which is found throughout the plant. Its function is to transport water and minerals throughout the plant. This tree contains xylem.

Phloem: Phloem is the other type of transport tissue in plants. Phloem is located in stems, leaves and roots. Its function is to transport food and nutrients around the plant for energy. These trees contain phloem.

Cellular Respiration: Cellular respiration is a process in which the body obtains energy through food/sugars and oxygen. In eukaryotic cell, this process occurs in the mitochondria. My dog performs cellular respiration in order get energy to perform activities.

 

Cellulose: Cellulose is a polysaccharide made up of chains of linked glucose molecules. Cellulose makes up most of cell walls in plants. It provides structure to plants.
