These are female gymnosperm cones. These cones contain ovules which eventually become seeds when the pollen produced by the male pine cones fertilizes it. This is how conifers reproduce.
This is a picture of an amniotic egg. The outer shell layer protects the egg. It also allows for gas exchange but holds in essential fluids like water for the egg to develop. Inside of this egg there is an embryo and a yolk which is nutrient rich.
These are lobster legs and are an example of an exoskeleton. Lobsters have an exoskeleton which is the external skeleton that supports the animals bodies. This is unlike humans who have endoskeletons.
The ovary is the innermost part of the flower and is the female reproductive structure. The ovary contains ovules which will eventually be fertilized by pollen. The ovules will turn into seeds and eventually the ovary turns into a fruit.
This is my hand which is covered with epithelial tissue like the rest of my body. My skin is what separates the internal and the external of my body. Some uses for epithelial tissue are protection, secretion (we sweat to cool off), and water tight.

Nice start! Consider including things like what the lobster's exoskeleton is made of, and where in the flower you would actually find the ovary. And don't forget your personal item in each picture!
