Where do animals that eat other animals (carnivores) get
their energy?

What is the ultimate source (either directly or indirectly) of
all energy for plants and animals?

What would happen to life on Earth if the sunlight were
blocked from the earth’s surface?
____________________________________________
All cells are small in size.

The first cells were not seen until the late __________ when
early microscopes were developed.

Why are organisms made of many small cells and not one big
cell?
…because cells depend on the process of ____________ to
move many substances through the cell and in and out of the cell.
Diffusion is very ______________.
Eukaryotic cells all have similar features

The control center of the cell is called the ____________.
 It is enclosed by a double membrane called the
___________
__________________.
 Openings in the nuclear envelope called __________ allow for
movement of substances in and out of the nucleus.

 Structures inside the nucleus that contain DNA and proteins are
called _____________________.
 Since DNA cannot leave the nucleus, genetic information is
copied into molecules of __________ and sent out into the
cytoplasm. This information is used to manufacture
