Specialized structures that work together inside a cell are called ? A. nuclei B. organelles C. eukaryotes D. prokaryotes

B. organelles

A membrane-bound sac used to transport substances into and out of the cells is a ? A. pump B. vesicle C. lysosome D. macrophage

B. vesicle

What is the process by which cells becomes specialized in structure and function? A. Neurotransmission B. Cell Specialization C. Cell Differentiation D. Organ system

C. Cell Differentiation

genetic material that contains instructions for making proteins.

C. DNA

Which of the correctly describes the relationship between tissue and organs? A. Several organs interact to help make tissue carry out a specialized function. B. One type of specialized tissue is found in each organ. C. Organs are made up of different types of tissue that work together. D. Tissues complete with each other to carry out the main functions of the organ.

C. Organs are made up of different types of tissue to work together.

A group of similar cells that work together to perform a specialized function.

C. Tissue

What level of organization is the most basic unit of life?

Cell

Which three organelles are found in plant cells but not animal cells? How are these structures related to functions at the organism level?

Chloroplasts- make energy from sunlight; cell wall- to give the cell a right shape; central vacuole- to store energy, waste, and water and to help give its shape the chloroplasts helps the leaves do photosynthesis and the cells wall and the vacuole keep the leaves strong and not droopy

The most basic unit of life.

D. Cell

Which of these best describes the nuclear membrane. A. It is rigid and impermeable B. It is identical in composition to the cell membrane C. It allows all molecules to pass across it into the nucleus D. It contains pores that allow only certain molecules to pass

D. It contains pores that allow only certain molecules to pass

Allows certain things to pass into and out of the nucleus

D. Nuclear envelope

Which of the following organ systems must work together to bring oxygen to the body's cells? A. digestive system B. skeletal system C. immune system D. respiratory system E. circulatory system

D. respiratory system; E. circulatory system

Which of these organelles can be found in the cytoplasm and on the surface of the ER? A.lysosomes B. centrioles C. mitochondria D. ribosomes

D. ribosomes

The process by which cells become specialized in the structure and function.

E. Cell Differentiation

site where proteins are made

E. Ribosomes

Part a cells that controls the movement of materials into and out of a cell.

F. Cell membrane

Proteins are created inside of here and then shipped to the Golgi

F. Rough ER

Part of the cell that acts as a storehouse for most of the genetic information (DNA).

G. Nucleus

breaks down drugs and alcohol

G. Smooth ER

Extra credit

Glucose

Contains enzymes that recycle old organelles.

H. Lysosomes

Known as the ¨Powerhouse¨ of the cell because it supplies the cell with energy in the form of ATP.

H. Mitocondria

Organelles that carry out photosynthesis in plant cells

I. Chloropast

What is the difference between rough ER and smooth ER? Explain the function of each.

Rough ER helps build protein and is a resting place of the ribosomes. The smooth ER breaks down alcohol and drugs.

A researcher is studying a cell process. The diagram shows the process. Identify the process shown in the diagram and explain why it is important in multicellular organisms.

The process is called cell differentiation and it is important in multicellular organisms because there are many different types of jobs in the organism.

Explain how a protein created inside of a cell is exported outside the cell membrane. Be sure to explain the various organelle or cell structures involved in this process.

The ribosomes make the protein inside the rough ER. Then the rough ER send it out in the cell in a vesicle that goes to the Golgi that filters the protein that ships it ot in a vesicle to the membrane it attaches to the membrane and the membrane send it out of the cells

When a plant wilts, its leaves shrivel. How is this phenomena related to the function of the central vacuole in the plant system.

The vacuole does not have enough water and shrivel and is no longer pushing on the cell wall

Place the following levels of organization in order from smallest to largest (most inclusive): Organ, cel, tissue, organ system, organism

cell, tissue, organ, organ system, organism

Which type of cell would have more mitochondria- a muscle cell or skin cell? Explain your answer.

muscle because it requires more energy

List any four types of cells

white, red, skin, muscle, nervous, stem, leaf, root, plant, animal
