1. Genetic variation within a population
This is a picture of a class of humans. This is an example of a population with genetic variations. A genetic variation is anything that makes one organism different from another organism. In this population, there are many genetic variations present. There are boys and girls, which is a variation of the X and Y chromosome when in the womb. Some people have brown hair, while others have blonde. The hair color is the phenotype, but the gene is what determines how much eumelanin and pheomelanin is released. Every species has genetic variations that cause different mutations, hair colors, and many other variations.

2. Phloem
This is a picture of a tree stump. This tree stump shows an example of phloem. Phloem is the tissue of a plant that transports water throughout it. The phloem of a tree would be it's trunk. The trunk allows sugar and water to be brought from photosynthetic leaves to areas which aren't photosynthetic. This restores the plants energy an hydration, allowing it to continue to photosynthesis and grow. The trunk is the phloem of a tree, just like the stem is the phloem of a flower.
3. Eukaryote
This is a picture of a tree. This tree is an example of a eukaryote. A eukaryote is a multi-cellular organism that has a nucleus in it's cell and a membrane surrounding it. The plant cells that make up this tree have mitochondria, a nucleus, endoplasmic reticulum, a vacuole, and many other things in them. Each cell has a cell membrane and cell wall surrounding what's inside it. Almost every organism on this planet is a eukaryote.
4. Basiodiomycete
This is a picture of a mushroom. A mushroom is a basiodiomycete. A basiodiomycete is a fungus with sexually produced spores on a basidium, or a club shaped structure. Basidia and basidiospores are produced on the underside gills of the mushroom, or the lamella. These spores are what helps the mushroom to reproduce and spread itself around an area. Some basidiomycetes reproduce sexually while others reproduce asexually.
5. Gymnosperm cone
This is a picture of a pine cone. A pine cone is an example of a gymnosperm cone. A gymnosperm cone is the gametophyte of the plant. The male cones carry the pollen while the female cones carry generate the seeds. Since the male cones are further up in the tree, the pollen they release falls onto the female cones who are then fertilized. The female cones store the seed while the zygote grows into an embryo. Once this has happened, the seed is released to grow another plant.
6. Pollinator
This is a picture of a bee. A bee is an example of a pollinator. A pollinator is any organism that carries pollen from one plant to another in order to fertilize that plant. This bee can land on one flower and get pollen on his body, wings, and legs. When he flies, the pollen can fall of onto other plants or he could deposit it when he lands on another plant. Most insects are pollinators, as well as some mammals and reptiles.
