(Fermentation)







Fermentation is an energy releasing process that occurs with a lack of oxygen. The results of fermentation are the break down of carbohydrates and other complex organic substances into simpler substances. In yeast and in most plant cells, fermentation produces ethyl alcohol, which is the most important ingredient in beer and wine, water and carbon dioxide.

(Endotherm)

An Endotherm is a warm blooded animal; an animal that can create internal heat. Endotherms regulate body heat to maintain a constant temperature. Animals have evolved various strategies to regulate their body temperature. Some animals such as dogs pant while others sweat to reduce their body temperature. In the picture there are two legs that are connected to a human body. Humans are examples of endothermic animals.

(Fungi)

Fungi is the kingdom of Eukaryotic organisms that don't have vascular tissues and chlorophyll. Fungi can reproduce through its asexual pores and sexually produced pores or just through its asexual pores.Fungi reproduced by both asexual and sexually produced pores are called perfect fungi while fungi reproduced with only asexual pores is called imperfect fungi . An example of fungi would be the mushroom, Honey Fungus (Armillaria mellea)(above). this mushroom appears to have fallen off of the stem that was once connected to a tree.

(Ectotherm)

An ectotherm is a cold blooded animal; an animal that can only can't maintain their own body temperature so it is determined by the environment it is in . They are dependent on an external source of body heat. some examples of this would be snake burrowing to lower its body temperature or a lizard laying out in the sun to raise it's body temperature.Another example of an ectotherm would be a turtle (above).

(Enzyme)

An enzymes are proteins made by the body. enzymes catalyze,increase the rate of chemical reactions in the body. some examples of enzymes are amylase. Amylase is secreted from salivary glands and the pancreas to help the digestion of carbohydrates. A car acts as a catalyst because it can help do everyday tasks faster than walking or riding a bike.

(Carbon)

Carbon is the chemical element number 6 that is a non metal and its main forms are diamond (above) and graphite.Carbon is present in all organic compounds and is one of the building blocks of life.

(Cellular Respiration)

Cells harvest energy stored in food by using cellular respiration.As shown in the diagram, cellular respiration produces ATP (Adenosine Triphosphate). It is a high energy molecule that is expanded by working cells. Carbohydrates, fats, and proteins are used as fuel in cellular respiration to create ATP. When we eat carbohydrates, the digestion  converts them into simple sugars which are carried to cells and stored in various tissues in the body such as liver, muscle and brain. These sugars get broken down by cellular respiration into pyruvic acid and ATP. ATP is used by the cells for energy.

(Photosynthesis)



Photosynthesis is when green plants and some other organisms create carbohydrates and sugars from carbon dioxide , water and sun as an energy source. Most forms of photosynthesis release oxygen as a byproduct.


( Epithelial Tissue)

Epithelial tissue can be found on the outside of an organ or organism. It protects underlying tissue from injuries. Epithelial tissue can be found in the lining of the stomach (above).

(Aggregate Fruit)


An aggregate fruit is a fruit that is formed from several carpels ( female reproductive organ of the flower) that came from the same flower. An example of an aggregate fruit is raspberry.Above is a picture of a raspberry bush that grows in my backyard and blossoms in the beginning of Summer.

( Autotroph )

An autotroph is an organism that creates carbohydrates, fats, and proteins from inorganic molecules such as sunlight through photosynthesis. Examples of autotrophs are plants(above) and algae.

(Acid)

An acid is a substance that has a pH of less than 7.Acids are sour in taste and can burn or destroy substances that they come in contact with. Acids also leave a stinging effect on mucous membranes.Examples of acids are lemon juice, orange juice (citric acids), acid rain and vinegar (above).

(Invertebrates)

Invertebrates are animals that have no back bone. Some examples of invertebrates are worms, jellyfish, and starfish (above). About 97% of the animal species is made up of invertebrates.
