Define commensalism.
one species benefits from the relationship, while the other is neither helped nor harmed. (+,0)
What is the role of chlorophyll in photosynthesis?
The role of chlorophyll in photosynthesis is to absorb light energy and use it to power the process of converting carbon dioxide and water into glucose and oxygen gas.
What are macromolecules?
Large, complex molecules that are made up of smaller subunits called monomers.
What is the function of the cell membrane in a cell?
The primary function of the cell membrane is to act as a barrier and regulate the movement of substances in and out of the cell.
What is an organ system?
A group of organs that work together in an organism
True or False: Parasitism is a type of ecological relationship where one organism benefits and the other is harmed.
True
What are the reactants and products of photosynthesis?
6CO2 + 6H2O + light energy → C6H12O6 + 6O2
What are the four main classes of macro molecules?
Carbohydrates, proteins, nucleic acids, and lipids.
True or False: Ribosomes are responsible for synthesizing lipids in the cell.
False
What is the eight level or organization?
Population
True or false: Commensalism is a type of ecological relationship where one organism benefits and the other is harmed.
False
How do plants use the glucose produced in photosynthesis?
Cellular respiration
What is the monomer unit of proteins
Amino acid
What is the function of the cytoskeleton in a cell?
Maintaining cell structure, enabling cell movement and division, and facilitating intracellular transport.

Two species of fish that occupy the same area of a river and feed on the same type of aquatic insects are in competition for the same food source. Which type of relationship is this?
Competition
Where in a plant cell does photosynthesis occur?
Chloroplasts
What is the function of carbohydrates in living organisms?
providing energy and supporting cell structure and function.
True or false: The endoplasmic reticulum (ER) is a network of flattened, membrane-bound sacs and tubes that is involved in protein and lipid synthesis.

Cuckoo birds lay their eggs in the nests of other bird species, and when the cuckoo chicks hatch, they push the host bird's eggs or chicks out of the nest. The host bird is harmed by the loss of its own offspring, while the cuckoo chick benefits from the food and care provided by the host. Which type of relationship is this?
Parasitism
What environmental factors can affect the rate of photosynthesis?
Light intensity, carbon dioxide, temperature, water availability, and nutrient availability
