Cell Biology: Animals and Plant Cells
Which structure in a plant is at the same level of organization as a heart in an animal? shoot system leaf chloroplast dermal tissue
leaf
Which structure is found in some but not all plant cells? vacuole ribosome cell wall lysosome
lysosome
Why do plant cells need chloroplasts?
- Plants need chloroplasts to capture light energy. - Plant cells use light energy to make food. - The cell uses the energy from food.
What is the main difference between a prokaryotic cell and a eukaryotic cell?
- Prokaryotic cells have no nuclei. - Eukaryotic cells have nuclei. - Eukaryotic cells contain membrane-bound organelles, while prokaryotic cells do not.
A scientist is using a microscope to observe a type of bacteria. Which two structures would the scientist most likely see? nucleus and DNA DNA and cell wall cell wall and vacuole vacuole and nucleus
DNA and cell wall
Which compares prokaryotes and eukaryotes? - Prokaryotes have DNA, and eukaryotes do not. - Eukaryotes have DNA, and prokaryotes do not. - Prokaryotes are multi-celled, and eukaryotes are single-celled or multi-celled. - Prokaryotes are single-celled, and eukaryotes are single-celled or multi-celled.
Prokaryotes are single-celled, and eukaryotes are single-celled or multi-celled.
A scientist is observing onion cells and human cheek cells under a microscope. Which observation does she most likely make? - The onion cells have lysosomes, and the cheek cells do not. - The cheek cells have larger vacuoles than the onion cells. - The cheek cells have a nucleus, and the onion cells do not. - The onion cells have a cell wall, and the cheek cells do not.
The onion cells have a cell wall, and the cheek cells do not.
a group of cells that work together to perform a specific function.
Tissues
A scientist is observing a eukarotic cell and a prokaryotic cell. Which structure could she only observe in the eukaryotic cell? cytoplasm DNA ribosomes a nucleus
