Commensalism

50.

The picture above shows commensalism. Commensalism is between two organisms where one organism benefits while the other organism is not impacted or affected. The picture shows the plant leaning and growing against the wall. The wall is neither affected nor disturbed, while the plant is benefiting from leaning against it.


Bilateral Symmetry

49.

The picture above displays bilateral symmetry. Bilateral symmetry is when both sides of the organism are identical.

Population

48.

The picture above shows an ant's population. A population is a group of organisms of a specie that live in the same time and place.

Gibberellins

47.

Gibberellins are a plants' hormone that regulates the development and growth. This hormone is used for many plants and fruits, such as grapes.

Unicellular Organism

46.

The photo above displays yeast, a unicellular organism. A unicellular organism is an organism that consists of only one cell, unlike a multicellular organism that consists of multiple cells.

Mycelium

45.

The picture above displays mycelium, which is the vegetative part of fungus. A single spore germinates into a homokaryotic mycelium, which cannot reproduce sexually. When two compatible homokaryotic mycelia join and form a dikaryotic mycelium, that mycelium may form fruiting bodies such as mushrooms.

Rhizome

44.

The photo above shows ginger, which is a rhizome. A rhizome is a modified stem of a plant that is usually found underground, often sending out roots. Rhizomes develop from axillary buds or grow perpendicular to the force of gravity.

Modified Stem of a Plant

43.

The picture above displays onions, which is consisted of modified stems covered by modified leaves, creating layers. Inside the onion, there is a bulb, which is the modified stem of the onion.

Adaptation of a Plant

42.

The photo above has collard greens and it is showing its adaptation. An adaptation of a plant is what the plant does, in order to survive. In this photo, the collard green has those ridges so it could preserve its water more and the green can grow. 

Eubacteria

 41.


The picture above shows eubacteria, which is found in yogurts. Eubacteria is considered "true" bacteria. Yogurt consists of milk and bacteria and it is fermented.

Lipid Used for Energy Storage

40.

The photo above shows butter, which is a lipid. Lipids are fatty substances and its main function is used for storage.

Tropism

39.

The photo above shows tropism in a plant. Tropism indicates growth or the turning movement of a plant, in response to an environmental stimulus. The direction the leaves grow is caused by the way the sun light hits the plant.

Modified Root of a Plant

38.

The photo above shows carrots, which are modified roots. The carrots are both an example of both a modified underground root and of a modified tap root. Tap roots store food and allow the carrot to take the shape it has. 

Succession

37.

Secondary succession is shown in the picture above. Secondary succession is one of the two types of ecological succession of plant life. As opposed to the first, primary succession, secondary succession is a process started by an event, a forest fire, that reduces an already established ecosystem. The photo shows that the vegetation is burnt away.

Endosperm

 
36.

The picture above shows coconuts, which contain endosperms. Endosperms are the tissue produced inside the seed of most flowering plants during the time of fertilization. It surrounds the embryo and provides nutrition in the form of starch, though it can also contain oils and protein. In this case, the endosperm is the edible portion of the coconut, the white part and the coconut water.

Ethylene

35.

The photo above shows a nectarine, which is sprayed with ethylene. Ethylene is an important natural plant hormone, used in agriculture to force the ripening of fruits.

Epithelial Tissue

34.

The photo above shows my hand, which has epithelial tissue. Epithelial tissue is the outer tissue of your body, your skin. This tissue can filter, absorb, and diffuse various substances, and it is also involved in sensory perception and bodily secretions.



Enzyme

33.

The photo above shows a picture of bananas, which contain enzymes. Enzymes aid in digestion purposes.

Fermentation

32.

The picture above shows wine,  fermentation. Fermentation is a metabolic process converting sugar to acids, gases and/or alcohol using yeast or bacteria. The process is often used to produce wine and beer, but fermentation is also involved in preserving foods.

Ectotherm

31.

The photo above shows fish, which are ectothermic. Ectothermic animals are usually reptiles and amphibians, which are cold-blooded. Fish are cold blooded animals making them ectotherm. Its body temperature can change depending on its environment and surrounding.
