Cell Biology: Nucleus Function

What is identified in both animal and plant cells?

• The nucleus.

• The cell wall.

• Chloroplasts.

• Mitochondria.

Learned Behaviors

• Tying your shoes before going to bed

• Tying your shoes when getting ready for school

• Putting on a jacket when it's cold

• Washing your hands before meals

Heredity

• The process of natural selection

• The passing of traits from parent(s) to offspring

• The study of genes and DNA

• The variation of traits within a population

What is the function of the nucleus in both animal and plant cells?

• It produces energy for the cell.

• It controls the activities of the cell.

• It stores genetic information.

• It helps in cell division.

genes

• determine your physical traits such as skin, eye, and hair color

• are responsible for your emotional responses

• control your height and weight

• influence your taste in music

A teacher showed her students a picture of a tree that does not lose all its leaves every year.

• insect, arachnid, crustacean, and mollusk

• fungi, bacteria, viruses, and protozoa

• algae, moss, fern, and flowering plants

Offspring

• product of one or more parents

• a type of genetic mutation

• a stage in the life cycle of an organism

• a method of reproduction

In the 1670s, Antony Leeuwenhoek discovered microorganisms in the human mouth. Later these microorganisms were determined to cause dental plaque, which is harmful to teeth. Which of these describes another way microorganisms can be harmful?

• Microorganisms break down meat before it is eaten.

• Microorganisms help in digestion of food.

• Microorganisms are used in the production of yogurt.

• Microorganisms can enhance the flavor of food.

A teacher shows her class a drawing of a plant cell. A student states that the function of the cell membrane is to maintain the cell’s shape. The teacher states that this is incorrect. Which description provides the correct function for the cell membrane?

• It provides structural support to the cell.

• It controls what enters and leaves the cell.

• It stores genetic information.

• It produces energy for the cell.
