Chapter 8 Cell Review

Despite differences in size and shape, at some point, all cells have DNA and a

• cell wall

• mitochondrion

• cell membrane

• nucleus

German scientists Schleiden and Schwann determined that the basic unit of structure and function in living things is the

• atom

• cell

• molecule

• nucleus

The portion of the cell outside the nucleus is called the

• organelle

• cytoplasm

• nucleolus

• ribosome

Proteins are assembled on

• ribosomes

• vacuoles

• lysosomes

• centrioles

Which of the following organelles converts light energy into chemical energy stored in food?

• Nucleus

• Chloroplast

• Endoplasmic Reticulum

• Protein Channel

Which organelles are know as the "powerhouse of the cell" because they transfer chemical energy from food to compounds the cell can use?

• Mitochondria

• Ribosomes

• Lysosomes

• Vacuoles

Which two organelles are involved in the movement of a cell in its environment?

• microtubules and centrioles

• flagella and cilia

• centrioles and the cell wall

• cytoskeleton and lysosomes

The relatively constant internal physical and chemical conditions that all organisms must maintain to survive is known as

• osmosis

• endocytosis

• homeostasis

• exocystosis

Solute particles move from an area of high concentration to an area of low concentration in a process called

• osmosis

• transport

• diffusion

• equilibrium

Large molecules such as glucose move across cell membranes through special protein channels during

• active transport

• facilitated diffusion

• osmosis

• bulk transport
