Test 3 Cells and Organelles

A rigid structure that surrounds the cell membrane and provides support to plant cells.

• Cell Wall
• Cytoskeleton
• Organelle
• Flagella

Tiny cell structures that carry out specific jobs within the cell

• Vesicles
• Cell Wall
• Organelles
• Ribosomes

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?

• Cell Membrane
• Ribosome
• Cell Wall
• Nucleus

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

• 25xx
• 35x
• 100x
• 250x

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.

• bringing in nutrients and water
• conducting nerve signals
• getting rid of wastes
• obtaining energy
• helping to produce a new organism

DIRECTIONS for how to build proteins.

• Cytoplasm
• DNA
• Ribosomes
• Mitochondria

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?

• Chloroplast
• Mitochondria
• Vacuoles
• Golgi

Which of the following is true of ALL cells?

• All cells contains ribosomes, DNA, cytoplasm and a cell membrane
• All cells are surrounded by a cell wall and a cell membrane
• All cells are made up of tissues
• All cells have a nucleus

Photosynthesis takes place in the:

• mitochondria
• chloroplasts
• cell wall
• nucleus

Packages and ships materials out of cell in vesicles

• Rough ER
• Golgi Complex
• Cell Membrane
• Nucleus
