Which feature best shows that a cell exhibits the characteristics of life?
It is visible only under a microscope
It contains organized structures that obtain energy and remove waste
It can be found inside rocks
It is colorless and tasteless
Which structure controls the cell’s activities and contains genetic information?
Mitochondrion
Ribosome
Nucleus
Chloroplast
Which organelle is the primary site of cellular respiration and ATP production?
Lysosome
Golgi apparatus
Mitochondrion
Cell membrane
Which pair correctly matches organelle to function?
Chloroplast — breaks down waste materials
Lysosome — photosynthesis
Ribosome — protein synthesis
Vacuole — houses genetic material
A plant cell differs from an animal cell because it has:
A nucleus and cytoplasm
A cell wall and chloroplasts
Mitochondria and lysosomes
A cell membrane only
Which sequence correctly orders levels of biological organization from smallest to largest?
Tissue → Cell → Organ → Organ system
Cell → Tissue → Organ → Organ system
Organ system → Organ → Tissue → Cell
Organ → Cell → Tissue → Organ system
Which best explains how the cell membrane and cytoplasm help maintain homeostasis?
Membrane produces energy; cytoplasm stores DNA
Membrane regulates transport; cytoplasm contains reactions that process materials
Cytoplasm prevents movement; membrane digests nutrients
Membrane and cytoplasm are both rigid barriers
During photosynthesis, chloroplasts produce sugar and oxygen. Which organelle later uses sugar to release energy?
Nucleus
Lysosome
Mitochondrion
Cell wall
Which organelle pathway is correct for synthesis and export of a secreted protein?
Ribosome → Endoplasmic reticulum → Golgi apparatus → Cell membrane
Golgi apparatus → Mitochondrion → Ribosome → Nucleus
Lysosome → Vacuole → Chloroplast → Ribosome
Nucleus → Cell wall → Mitochondrion → Cytoplasm
A cell that cannot make ATP would most likely have a malfunctioning:
Cell membrane
Mitochondria
Ribosomes
Chloroplasts
Which observation would best support the claim that a sample contains living cells?
The sample dissolves in water
The sample grows, produces waste, and responds to stimuli
The sample is made of a single material
The sample reflects light differently at different angles
Which organ system interaction is correctly paired?
Respiratory system supplies oxygen to the digestive system for nutrient breakdown
Circulatory system transports nutrients from the digestive system to body cells
Muscular system filters blood in place of the excretory system
Immune system digests food for use by cells
How do organelles work together when a plant cell makes sugar?
Nucleus digests sugar while lysosomes store sunlight
Chloroplasts capture light energy; mitochondria convert some sugar to usable energy
Cell wall converts carbon dioxide to oxygen; vacuole breaks down sugar
Ribosomes produce oxygen; Golgi packages sunlight
Which is an example of asexual reproduction?
Two parents produce offspring with mixed traits
A single parent produces genetically identical offspring by budding
Gametes fuse to form unique offspring
Cross-pollination between two plants
Which statement describes sexual reproduction compared to asexual reproduction?
Sexual reproduction produces genetically identical offspring; asexual produces variation
Sexual reproduction requires one parent; asexual requires two
Sexual reproduction increases genetic variation among offspring; asexual does not
Sexual reproduction only occurs in plants; asexual only in animals
A student draws two cell diagrams. One has a cell wall and chloroplasts; the other lacks both. The correct identification is:
Both are animal cells
Both are plant cells
First is plant cell; second is animal cell
First is animal cell; second is plant cell
Which organelle would be most important for a cell that secretes large amounts of protein?
Golgi apparatus and rough endoplasmic reticulum
Chloroplast and cell wall
Lysosome and vacuole
Mitochondrion and peroxisome
Which best explains why multicellular organisms have specialized cells, tissues, and organs?
To increase randomness of cell functions
To allow groups of cells to perform specific tasks efficiently and maintain homeostasis
To prevent cells from communicating with each other
To reduce the number of organelles needed per cell
Which evidence would weaken the claim that a structure is a living cell?
It grows, uses energy, and adapts to light changes
It shows DNA, reproduces, and responds to stimuli
It never changes, does not metabolize, and does not respond to the environment
It organizes molecules into functioning parts
Which sentence best describes how organ systems interact during exercise?
The nervous system signals muscles to move; respiratory and circulatory systems deliver oxygen and remove carbon dioxide and waste
The digestive system directly controls muscle contraction without nervous input
The immune system powers muscles by producing ATP
The skeletal system produces oxygen for the circulatory system
