One characteristic of all living things is that they are all made of units. What are these units called?
Tissues
Cells
Organs
Body Segment
Which statement is correct?
Most single celled organisms can be seen with a hand lens.
People can see blood cells if they are viewed under a microscope.
People can see cell walls under a microscope but not the nucleus.
The cell’s nucleus looks larger under a microscope.
Tracy is comparing a small piece of a leaf and part of a butterfly wing. She places the leaf under a microscope, and the butterfly wing under another microscope.0 Based on her experiment, which statement could we infer is correct?
Both the leaf and the butterfly are made up of cells.
The leaf is made up of cells, but the butterfly wing is not.
The butterfly wing is made up of cells, but the leaf is not.
The leaf and butterfly wing are not made up of cells.
Mark can see little rectangles when he looks at the cells of an onion skin with a microscope, as shown in the diagram below. His teacher asks him to identify what he is observing and explain how he came to that conclusion. Based on his observations, which conclusion would be the best answer?
The onion skin has this pattern because it is old. The lines and wrinkles cab be seen with the microscope.
It has little rectangles that are scales protect the onion and give it shape.
The rectangles are plant cells that can only be seen through a microscope. The cells are the building blocks of living things and an onion is a living things.
The rectangles are the same shape and do not move. The onion skin is made of non-living material. The rectangles give it shape.
A group of students want to prove that living things are made up of cells. Who would have the most effective way to design an investigation to collect evidence to support their claim?
Tom would like the group to observe an insect closely and draw each body part in a science notebook.
Carlos would like the group to use a magnifying glass or hand lens to observe a flower petal before and after it is crushed. The two observations would be recorded and compared using a chart.
Maria would like the group to use a microscope to observe a soil, rock and salt sample. They would draw the cells in their science notebook and create a Venn diagram to compare and contrast each item.
Keisha would like the group to use a thin piece of an elodea plant and place it under a microscope. A model is made from the observation and it is labeled. They would then compare it to the skin from the leaf of a cabbage and root hairs from a plant. The group would make a comparison chart to record their observations.
How are plant cells different from animal cells?
Plant cells look more orderly than animal cells.
Plant cells have cell walls and animal cells do not.
Plant cells have a nucleus and animal cells do not.
Plant cells are smaller in size than animal cells.
Which of the following is NOT correct about the cytoplasm within cells?
Cytoplasm is only found in animal cells.
Cytoplasm holds components that help materials move around the cell.
Cytoplasm helps dissolve cellular waste.
Cytoplasm appears as a gel-like liquid that surrounds organelles.
A student is studying a diagram of a cell. He can see a cell wall, cell membrane and a nucleus. Using these observations, what can the student conclude about the cell?
It is likely from a dog.
It is likely from a tree.
It is likely from a fish.
It is likely from a spider.
A scientist is studying the blood cells from two different animals, a frog and a mouse. Which of the following is most likely to be the same?
The number of chloroplast because they make their own food.
The shape of the cell walls because the cells have a rigid structure for support.
The size of the vacuoles because each cell must store the same amount of water and waste.
The number of nuclei because each cell will have a control center that directs the organelles.
A biologist has been studying the cells of an unknown living organism. She has recorded her observations and has given them to you so that this new organism can be given what it needs to survive. Which is the best care plan for this organism and why?
The organism should be placed near the sunlight. It requires light to in order to create its own food. This food will give energy to the cells.
The organism does not require water. There are enough vacuoles to support water storage.
The organism needs to be fed. It requires food from an outside source to obtain energy.
All of the above plans should be followed. It cannot be determined by this information if the cells came from a plant or an animal.
Both the plant and animal cell have a control center that tells the cell and its organelles what to do. Which organelle correctly identifies this description?
The cell wall
The nucleus
The vacuole
The cytoplasm
Which structure in animals functions in the same way as a cell wall in plants?
heart
finger
eye
skin
A group of friends are discussing how to use real world objects as a comparison for a plant cell model. Who has the best idea for the comparison model?
Shelly: We could use a car as a model of a cell. The steering wheel could be the nucleus;it turns the car in the right direction. The wheels could be the cell wall because it holds it off the ground. The seats could be the cell membrane because the organelles sit on it. The gas tank could be the chloroplasts because it makes food for the cell.
Mike: We could use a bedroom as a model of a cell. The walls of the house could be the cell membrane. The bed could be the nucleus because it is the most important part of the cell. The closet could be the vacuole because it stores things. The blankets are the cytoplasm; it covers the bed.
Monica: We could use the school as a model of the cell. The building is the cell wall, it has structure. The doors and windows are the cell membrane, they allow things in and out of the cell. The principal is the nucleus. He directs everything that happens in the cell. The storage closets are the vacuoles, to keep extra things and trash. The cafeteria is like the chloroplast that create food for the cell.
Devon: We could use an orange as a model of a cell. The skin could be the cell wall and membrane. The seeds could be the nucleus. The pulp could be the cytoplasm.
