"Small organs" of the cell that carry out specific functions

protective barrier that encloses all cells

controls the movement of materials into and out of the cell

What is the nucleus?

Multicellular means...

contains DNA, which has the information on how to make the cell's proteins control center for the cell. Sometimes called the brain of the cell.

Controls what enters/leaves a cell

Which organelle uses energy from sunlight to make sugar?

jello-like material, fills the space between cell organelles, is where many chemical reactions occur

What type of cell is shown?

“Powerhouse” of the cell, breaks food down into energy for the cell

Makes proteins, works like a “contractor”, building more cell parts

Break down molecules and dead organelles, works like a “garbage disposal”

Students use a microscope to look for structures present in four different cells. The students placed an X for each structure that was viewed for each cell on the table shown.

Which cell that was viewed is most likely a prokaryote?

Stores food and water like a refrigerator for the cell

Organelle that links amino acids together to make proteins.

Layered stack of flat membrane-enclosed spaces containing enzymes that process, sort, and deliver proteins.

Fluid filled sac for storage of materials; stores food, water, and enzymes.

This organelle is found only in plants; it takes up a lot of space and strengthens cells and helps to support the entire plant.

Dense area of the nucleus that is essential for making proteins.

Organelle composed of many membranes used to convert solar energy into chemical energy; contains chlorophyll and is where photosynthesis occurs.

A rigid structure that gives protection, support, and shape to plants, algae, fungi and some bacteria.

A network of proteins such as microfilaments, microtubules, that are inside of eukaryotic cells that support it and gives cells their shape.

A double-layer of phospholipids that forms a boundary between the cell and surrounding environment and controls the passage of materials into and out of the cell.

An interconnected network of thin, folded membranes that produce, process, and distribute proteins. Is covered in ribosomes.

An interconnected network of thin, folded membranes that produce, process, and distribute proteins. Is NOT covered in ribosomes.

Which table headings should the student use for the two groups?

A collection of different eukaryotic and prokaryotic cells are viewed through a microscope, as shown in the image. (click on it to view)

Which of the following correctly matches the type of cell with its label?

Prokaryotic cells differ from eukaryotic cells in that...

The diagram below shows muscle tissue in a human skeleton. This muscle tissue is full of protein. Though proteins are energy-rich they are not the first thing that the body breaks down, unless a person is doing heavy exercise.

When these proteins are broken down, they -

During photosynthesis, in addition to producing oxygen molecules for animals to breathe, plants also produce glucose. What purpose does glucose serve in an ecosystem?

An advertisement for a health supplement for dogs claims to build lean muscle and strengthen tendons and ligaments, as well as provide energy. Which two biomolecules must the supplement contain to provide these benefits?

Taq polymerase is an enzyme used in the polymerase chain reaction (PCR) to replicate fragments of DNA. A study published in 1976 examined the properties of Taq polymerase after the enzyme was isolated from Thermus aquaticus, a thermophilic bacterium that lives in the hot springs of Yellowstone National Park. The graph shows one of the results of the study.

Which statement about enzyme activity is best supported by this graph?

Which graph represents the effect that enzymes have on the activation energy of a chemical reaction?

Enzymes are molecules that help speed up reactions in your body. The graphs show the reaction rate for an enzyme across a range of temperatures and pH.Based on these data, this enzyme functions best at what temperature and pH?

A student preparing for a hike wants to pack a snack that has biomolecules

that provide quickly available energy but few excess calories. Which nutrition

label lists the best combination of biomolecules that provide quickly available

energy while providing the fewest calories from other types of biomolecules?

Proteins and carbohydrates have many functions in the body of an organism. Specific proteins and carbohydrates perform specific tasks. Information about a protein and a carbohydrate is given below. How are Ferritin and Glycogen similar in their primary functions for an organism?
