  7. This is a turtle my sister found in our yard. Turtles are examples of an ectotherm. Ectotherms are “cold-blooded” animals. They rely on its surrounding environment (such as sunlight or heated rocks) to regulate their body temperatures, unlike warm-blooded animals who regulate their bodies internally. Ectotherms need less food than warm-blooded animals, but often cannot live in the cold.

  8. The coconut meat we eat (and the coconut milk) is an example of an endosperm. Endosperms are tissues inside the seeds of flowering plants. In addition to coconuts, endosperms of wheat is used for whole wheat bread, and barley endosperm is used to make beer.

  11. These are some heads of lettuce from our garden. Lettuce is one of long-day plants. Long-day plants are plants that flower and grow in the summer because of the longer days and the shorter nights. These flowers only bloom when they have more than 12 hours of daylight.

  12. Yeast is an example of an unicellular organism. Unicellular organisms are any life form that only consist of one cell. They are also called single celled organisms.
