17. Lichen
This is a picture of fungi and alga on a tree. Note that the lichen in the picture above is not the plant growing on the left side, but rather it is the light green, dark green, and yellow mix of fungi and alga. This is an example of a lichen. A lichen is a slow growing group of fungi and alga that usually form leaf like or branching growth on rocks, trees, and etc. Lichen have a mutualistic relationship with the tree or rock that they grow on which means that both the fungi and alga and tree/rock benefit. Fungi and alga can be seen as partners in crime who come together and form a lichen.

15. Gymnosperm Leaf
This is a picture of a pine tree leaf. A pine tree leaf is an example of gymnosperm leaf. Gymno in greek means "naked" and sperm in greek means "seed" thus gymnosperm literally translates to "naked seed". This is true because gymnosperms seeds are not enclosed in an ovary. Pine trees are conifers which are a specific group of gymnosperms. There are different types of gymnosperm leaves. For example, coniferophyta have leaves resembles needles or scales while cycadophyta leaves are large and frond - like. There are also other kinds of leaves too.
14. Gymnosperm Cone

A pine cone is an example of a gymnosperm cone.Gymno in greek means "naked" and sperm in greek means "seed" thus gymnosperm literally translates to "naked seed". This is true because a gymnosperm is a vascular plant that's seeds are not enclosed in an ovary, but rather the seeds are in a cone such as the one seen in the above picture. Angiosperms are the opposite of gymnosperms and have seeds that are enclosed in an ovary. Most gymnosperms consist of cone bearing trees or shrubs. Some examples of gymnosperm cones are conifer cones, cycad cones, ginkgo cones, etc.
13. Genetically Modified Organism
This is a picture of seedless grapes. This is an example of a genetically modified organism because the grapes were genetically modified to be seedless. A genetically modified organism, also referred to as GMO. is an organism whose genetic code has been altered by artificial means such as interspecies gene transfer. Some examples of GMO include fruits like the grapes shown above, GM atlantic salmon, and Enviropig. GMOs are developed for many reasons and a few being that they are more pest resist or that they have no seeds and make it easier to eat.
12. Flower Ovary
This is a picture of a flower ovary. In the picture above the flower's ovary is located near the bottom of the the slit. An ovary is part of the female reproductive organ in a flower and is also the part of the pistil that holds the ovules. The ovary is usually located above the sepals, below the sepals, or in line with the sepals and the base of the petals. Some flower ovaries are easier to see than others.
