The characteristic of living things that is required for the species to survive but does not have to apply to an individual is reproduction. Individual organisms may not reproduce (e.g., they may die before having the chance), but for the species to continue, reproduction is necessary.

The organelle responsible for the difference between plant and animal cells in terms of using energy from the sun to make food is the chloroplast. Chloroplasts contain chlorophyll, which allows plants to perform photosynthesis.
Which statement about plasma membranes is correct?(1 point)
Responses
Both plant cells and animal cells have flexible plasma membranes.
Both plant cells and animal cells have flexible plasma membranes.
Plant cells have cell walls instead of plasma membranes.
Plant cells have cell walls instead of plasma membranes.
Animal cells have cell membranes instead of plasma membranes.
Animal cells have cell membranes instead of plasma membranes.
Plant cells have rigid plasma membranes.
Responses
Both plant cells and animal cells have flexible plasma membranes.
Both plant cells and animal cells have flexible plasma membranes.
Plant cells have cell walls instead of plasma membranes.
Plant cells have cell walls instead of plasma membranes.
Animal cells have cell membranes instead of plasma membranes.
Animal cells have cell membranes instead of plasma membranes.
Plant cells have rigid plasma membranes.
The correct statement about plasma membranes is:
Both plant cells and animal cells have flexible plasma membranes.
Plant cells do have a cell wall, but they also possess a plasma membrane. The plasma membrane is flexible and exists in both plant and animal cells.

The correct response regarding the function of the plasma membrane is:
It helps recognize other cells.
While the plasma membrane does play roles in maintaining cell shape and filtering substances, its primary functions include regulating what enters and exits the cell and facilitating communication and recognition between cells through various receptors.

The correct statement about the function of a pseudopod is:
It helps unicellular organisms move.
Pseudopods are temporary projections of eukaryotic cells, particularly in unicellular organisms like amoebas, that aid in movement and feeding.
