Angiosperm - a plant that produces flowers and seeds, the latter of which are enclosed in a protective structure (e.g. a fruit). A tomato plant is an angiosperm because it starts out as a flower bud with a seed-containing ovary; then, as the ovary grows larger, the flower becomes a tomato, and the seeds are found in the fruit. This angiosperm is from our vegetable garden... even though the tomatoes are technically fruits.

Animal that has a Segmented Body - an animal with a body divided into segmented units, like cars in a train, that often group together into larger functional units. A beetle is an animal with a segmented body. Its body is divided into three regions: the head, the thorax, and the abdomen, each of which has segments of its own. The beetle's legs alone are composed of five main segments. I found this beetle near some grass in my friend's yard, but by the time we photographed the little bugger, it had crawled onto the sidewalk.

Arthropod - an invertebrate with an exoskeleton, a segmented body, and jointed appendages. Butterflies do not have bones (an internal skeleton). Instead, each part of their bodies is covered with a hard coating that protects it (an exoskeleton). Like the beetle above, which too is an arthropod, this butterfly has a segmented body, as well. Attached to the butterfly's head, thorax, and abdomen are various appendages, such as six legs and four lovely wings. The picture of this butterfly on our windowsill is an example of an arthropod.
