vocabulary
a. cell
b. nucleus
c. cell membrane
d. cytoplasm
e. mitochondria

1. controls what enters and leaves the cell.
2. the basic unit of life.
3. jelly-like material that fills the inside of the cell.
4. the control center that contains dna.
5. produces energy for the cell.

Explanation:

Match definition 1

The definition "Controls what enters and leaves the cell" describes the selectively permeable barrier surrounding a cell. Using the Cellular Structure knowledge point, this is the cell membrane. Thus, definition 1 matches option C.

Match definition 2

The definition "The basic unit of life" is a core tenet of biology. Using the Cell Theory knowledge point, the cell is defined as the fundamental structural and functional unit of all living organisms. Thus, definition 2 matches option A.

Match definition 3

The definition "Jelly-like material that fills the inside of the cell" describes the fluid environment where organelles reside. Using the Cellular Structure knowledge point, this substance is the cytoplasm. Thus, definition 3 matches option D.

Match definition 4

The definition "The control center that contains DNA" describes the organelle responsible for storing genetic material and directing cellular activities. Using the Cellular Structure knowledge point, this is the nucleus. Thus, definition 4 matches option B.

Match definition 5

The definition "Produces energy for the cell" describes the organelle responsible for cellular respiration and ATP production. Using the Cellular Structure knowledge point, this power generator is the mitochondria. Thus, definition 5 matches option E.
