Cells (Unit 3)

Question 1

Cell

Answer 1

The basic building blocks of living things

Question 2

Organelle

Answer 2

The parts of a cell. Each one has a specific function

Question 3

Cell membrane

Answer 3

A thin, flexible barrier around the outside of all cells. This organelle controls what enters and leaves the cell (selective permeability).

Question 4

Cell Wall

Answer 4

A thick protective layer around the outside of plant cells. This organelle gives plant cells a stiff and rigid shape.

Question 5

Cytoplasm

Answer 5

The liquid that fills the inside of cells.

Question 6

Nucleus

Answer 6

The control center of cells. Contains the DNA of the cell (in eukaryotic cells)

Question 7

Chloroplast

Answer 7

The organelle that absorbs sunlight and turns it into sugar (photosynthesis)

Question 8

Mitochondria

Answer 8

The organelle that converts sugar into ATP energy.

Question 9

Ribosome

Answer 9
