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.

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.
