Tiny cell structures that carry out specific jobs within the cell

A virus can reproduce only inside a cell. Once inside, the virus causes the cell to make many new copies of the virus. In an animal, which part of the cell is responsible for keeping viruses out?

If the eyepiece has a magnification of 10x and the objective lens being used is 25x, then what is the total magnification?

Several kinds of specialized cells work together to create the sense of hearing. Hair-shaped cells sense vibrations and nerve cells send signals to the brain. Structural cells hold the hair cells in place. No matter their specialty, which functions must ALL CELLS perform to survive? Choose the three statements that apply.

DIRECTIONS for how to build proteins.

All the organelles in a cell work together to help the cell and the whole organism function. Some diseases are caused by the failure of one type of organelle. Read the description below of an example of this type of disease. Joe’s cells CAN NOT CONVERT FOOD ENERGY INTO ENERGY THEY CAN USE. As a result, he gets extremely tired, has weak legs, and can’t breathe well. Joe swims every day to keep his body as strong as possible. Which organelle is affected by Joe's disease?

Which of the following is true of ALL cells?

Photosynthesis takes place in the:

Packages and ships materials out of cell in vesicles

What part of the cell produces protein.

True/False: Lysosomes break down dead and waste particles in a cell.

What type of cell would have more mitochondria? A muscle cell or a skin cell?

Which statement is true about the cells in your body?

Which of the following statements is NOT part of the cell theory?

Materials stored inside of a vacuole include:

Farmers depend on a growing season to provide for their families. A growing season is the part of the year when rainfall and amount of sunlight allow plants to grow at a rapid rate. For many plants, especially crops that humans consume, the growing season occurs in the spring after the last frost and can last through the summer. You are to provide support for proving that additional sunlight during the growing season provides an increase in grow for plants. First, your teacher asks you to demonstrate the relationship between sunlight entering the plant cell and increased growth. How do two organelles in the plant cell work together so the plant can grow? Use the following flowchart to show this relationship. Select the correct order of the terms to fill in the blanks.

The endoplasmic reticulum:

If you were to compare your school to a cell, the nucleus would most likely be the:

How do you determine total magnification?

The cell part that acts like a barrier and lets some things in and out, and not others is the:

Before the invention of microscopes, scientists did not know about cells. Some thought that life just appeared out of nowhere. Microscopes allowed scientists such as Schleiden and Schwann to see organisms under high magnification. After much study, which ideas became parts of the cell theory? (Choose the three statements that apply.)

The ghost plant is white with a single stalk. Even though it looks more like a mushroom, the ghost plant is related to blueberry plants. The ghost plant is a parasite that feeds on fungi under the ground and does not preform photosynthesis. Ghost plant cells have all the usual plant organelles except for a:

What are the main differences between plant and animal cells?

Before a new medicine is approved, scientists study the effects the medicine has on different parts of the body. Often, a medicine is tested on mice before it is tested on humans. All the cells in the illustration below came from the same mouse. Four images of unique looking cells If all of these cells are mouse cells, why do they look so different from each other?

All the organelles in a cell work together to help the cell and the whole organism function. Some diseases are caused by the failure of one type of organelle. Read the description below of an example of this type of disease. A mosaic is a picture made up of small colored pieces. Mosaic viruses cause plant leaves to look like mosaic art. A mixture of dark and light green patches appear on the leaves. The light green patches are NOT ABLE TO CAPTURE MUCH ENERGY FROM SUNLIGHT. Which organelle is affected by mosaic viruses?

When focusing a specimen under high power, ONLY use the fine adjustment.

The main difference between Prokaryotic and Eukaryotic cells is the presence of:

Many species of bacteria live in your mouth and throat. These bacteria come from several different groups within domain Bacteria. You can avoid most bacterial infections by washing your hands frequently and not sharing food or eating utensils. Which characteristics are true of bacteria? (SELECT THE 3 THAT APPLY. )

Giant anteaters live in Central and South America. As their name suggests, they eat ants and termites. First, an anteater tears open insect nests with its long claws. Then, it extends its extremely long, sticky tongue into the nest to catch its prey. One anteater eats 35,000 ants and termites in a day. Which DOMAIN do anteaters belong to?

Billy's favorite food to eat (he makes it all by himself) is a cheeseburger, complete with lettuce, tomatoes and pickles. Billy is a:
