Cell Study Guide

Name 3 ways that plant cells are different than animal cells:

• Cell Wall

• Chloroplasts

• large vacuole

• cell membrane

• nucleus

All living things are made of units known as _______cells______________.

Check the box for each statement that is true. Leave the box empty if it is false.

• Organisms made of single cells can usually be viewed with a hand lens.

• People can see a nucleus under a microscope, but not a cell wall or cell membrane.

• Scientist can see individual blood cells if viewed under a microscope.

• The vacuole of an animal cell will usually appear larger than that of a plant cell when viewed under a microscope.

• The job of the nucleus is like a control center telling the cell and its organelles what to do.

Sophie observed the following image of an onion skin under the microscope: Mrs. McCord asks her to explain what she sees in the image, and how she knows. Put a check next to each statement that Sophie could correctly state.

• The rectangles are plant cells.

• The skin has lines because it is old and dried.

• The shape of all the cells must be rectangular if they are plants.

• The skin is made of non-living material, and the rectangles just give it rigid support.

• The dots are the nuclei, the organelle that controls the job of the cell.

What is the job of cytoplasm in both plant and animal cells?

• protects organelles

• dissolves waste (won't be tested on this)

Jelissa studies cells from a bumblebee and a grasshopper under a microscope. Which will she most likely observe in both of the cells and why?

• Both of the cells will have cell walls because they need the rigid support since they don't have skeletons.

• The size of the vacuoles will both be small, although not necessarily the same size, because they are both animal cells.

• Each cell will have the same number of nuclei to provide energy for the cell.

• The number of chloroplasts in each cell will be the same to help with food production.

The following table shows information gathered from various cell samples:

• Nucleus

• Cell Membrane

• Chloroplast

• Cell Wall

• Cell

Nathan is studying a dragonfly wing and a leaf from an oak tree by observing them under a microscope. Based on the images that Nathan observes, what can be concluded?

• The dragonfly wing is made up of cells, but the oak tree leaf is not.

• The oak tree leaf is made up of cells but the dragonfly wing is not.

• Both the dragonfly wing and the oak tree leaf are made up of cells.

• Neither the dragonfly wing nor the oak tree leaf are made up of cells.

Isaiah looks in a microscope and observes a cell membrane, chloroplasts, and a nucleus. Isaiah concludes that the cell is most likely which of the following?

• A human's blood

• A butterfly

• A celery stalk

• A shell

Dominic made the following drawing of one of the cell samples from the chart above. Which sample does the model match?

• It is an animal cell, so it could be Sample A or C.

• It is a plant cell, so it could be Sample B.

• It is an animal cell, so it could be Sample A, B, or C.

• There is not enough information to determine if the cell is a plant or animal cell.
