Cell Membrane and Water Movement Practice

A cell membrane is:

• Osmosis

• Diffusion

• Transpiration

• Selectively Permeable

• Permeable

Water enters or leaves cells by:

• Osmosis

• Diffusion

• Transpiration

• Selectively Permeable

• Permeable

Oxygen enters or leaves cells by:

• Osmosis

• Diffusion

• Transpiration

• Selectively Permeable

• Permeable

Water evaporates from a plant by:

• Osmosis

• Diffusion

• Transpiration

• Selectively Permeable

• Permeable

Why might a plant with a huge stem system and a tiny root system have difficulty surviving?

• It cannot absorb enough water and nutrients.

• It will grow too quickly.

• It will produce too many leaves.

• It will attract too many insects.

Why are cells specialized in multicellular organisms?

• To perform specific functions efficiently.

• To increase the size of the organism.

• To make the organism more colorful.

• To reduce the need for energy.

Name the main types of specialized cells in animals.

• Muscle, nerve, blood, and epithelial cells.

• Root, stem, leaf, and flower cells.

• Bone, cartilage, tendon, and ligament cells.

• Skin, hair, nail, and gland cells.

The structure of a specialized cell is related to its function in the body of a multicellular organism.

• The structure is adapted to perform its specific function.

• The structure is identical to all other cells.

• The structure is random and not related to function.

• The structure is designed to change functions frequently.

List some advantages that multicellular organisms have over unicellular organisms.

• Multicellular organisms can perform more complex functions.

• Unicellular organisms have specialized cells.

• Multicellular organisms are always smaller in size.

• Unicellular organisms can survive in more environments.

Name the five levels of organization in a multicellular organism and give an example of each.

• Cells, Tissues, Organs, Organ Systems, Organisms

• Atoms, Molecules, Cells, Tissues, Organs

• Cells, Organs, Organ Systems, Populations, Communities

• Tissues, Organs, Organ Systems, Organisms, Ecosystems
