biology - characteristics of life

A student collects plants and pebbles and places them in an aquarium to record observations. The sizes of the plants increased, but the pebbles did not. the student classifies the pebbles as nonliving. Which criteria does the student use as the basis of classification?

• ability to grow

• ability to move

• ability to reproduce

• ability to respond to stimuli

The nerve cells in a chef's hand sense heat from a pan. They signal to the brain which sends signals to the hand to release and drop the pan. Which TWO characteristics of living things does this action best demonstrate?

• the ability to respond to stimulus

• the ability to grow and develop

• the ability for sells to contain DNA

• the ability for evolutionary change

• the ability to move

Phototropic flowers grow toward the sun. Which characteristic of life do the phototropic flowers demonstrate?

• ability to reproduce

• ability to maintain homeostasis

• ability to respond to stimuli

• ability to pass traits onto offspring

A student places a spider and several stones in a clear container. He adds water and food everyday to determine which objects in the container are living and non living. The student uses the______ as the criteria for the classification of the objects.

• ability to grow and reproduce

• ability to use food for energy

• ability to pass traits to offspring

• ability to respond to stimuli

A student places a potted plant and a plastic straw in a closet for two weeks. He observes that the plant is brown and wilted while the straw remains the same. He classifies the plant as living and straw as nonliving. Which criteria did the student use?

• the plant needs energy from sunlight to make food for survival

• the plant produces pollen for reproduction of its species

• the plant generates sugars that are consumed as food by other organisms

• the plant produces offspring with characteristics similar to the parent

Robert Hooke observed cork tissue from a plant using a microscope and saw small, honeycomb-like structures. What contribution did Hooke make to biology based on his observation?

• he named the small structures organelles

• he named the small structures cells

• he stated that all living things come from preexisting cells

• he stated that every living thing is made up of more than one cell

Rudolf Virchow rejected the idea that living things could generate spontaneously from nonliving things. which part of the cell theory supports this?

• all organisms are made up of cells

• cells exist in various forms and sizes

• all cells come form preexisting cells

• cells are the fundamental units of life

Matthias Schleiden proposed that a plant grows by the division of cells and is composed entirely of cells. Which component of the cell theory is supported by this?

• the activity of an organism depends on the energy it consumes

• all living things are made up of one or many cells

• all cells are physically and chemically similar

• energy flow occurs within cells
