Biology Quiz

What is the basic building block of all organisms?

• Tissues

• Cells

• Organs

• Organ systems

What is the function of the mitochondria?

• Controls the cell's activities; contains chromosomes made of DNA

• Moves substances within the cell (pipe-like structures)

• Breaks down food to release energy

• Makes proteins; round structures located in rough endoplasmic reticulum

Which organelle is responsible for making proteins?

• Golgi body or complex

• Ribosome

• Lysosome

• Endoplasmic reticulum

What is unique to plant cells?

• Nucleus

• Cell wall

• Mitochondria

• Cytoplasm

What is the role of the Golgi body or complex?

• Suspends organelles in a eukaryotic cell

• Contains enzymes that speed up digestion and chemical reactions

• Changes and packages cell products

• Surrounds the cell; controls what enters/leaves the cell

What is the function of the lysosome?

• Holds material like water; large in a plant cell

• Contains chlorophyll (green pigment) for photosynthesis

• Surrounds the cell membrane; supports and protects plant cell

• Contains enzymes (proteins that speed up digestion and chemical reactions)

What is the difference between prokaryotic and eukaryotic cells?

• Prokaryotic cells contain chlorophyll, while eukaryotic cells do not

• Prokaryotic cells are complex, and eukaryotic cells are simple

• Prokaryotic cells are simple, and eukaryotic cells are complex

• Prokaryotic cells have a nucleus, while eukaryotic cells do not

What is homeostasis?

• The process by which cells obtain energy

• The process by which organisms keep internal conditions stable despite changes in external environment

• The movement of molecules across a cell membrane

• The synthesis of new materials within a cell

Why is homeostasis important for cells?

• It allows cells to move freely

• It enables cells to transport materials without energy

• It ensures that cellular processes necessary for life can take place

• It prevents cells from using energy

What is the plasma or cell membrane described as being?

• Rigid and inflexible

• Selectively permeable

• Completely impermeable

• Only allowing water to pass through
