Choose a term to complete the analogy.
Food storage
Water absorption
Buoyancy
Mechanical strength
Buoyancy
Remember the function of plant tissues: Chlorenchyma contains chlorophyll for photosynthesis, while Aerenchyma consists of large air spaces (aerenchyma cells) that provide buoyancy to aquatic plants.
Remember the function of plant tissues: Chlorenchyma contains chlorophyll for photosynthesis, while Aerenchyma consists of large air spaces (aerenchyma cells) that provide buoyancy to aquatic plants.
Analyze the analogy relationship
Chlorenchyma is a type of parenchyma tissue containing chloroplasts, which are essential for the process of photosynthesis in plants. This identifies a relationship of 'Tissue Type : Primary Biological Function'.
Evaluate the second term
Aerenchyma is a specialized spongy tissue with large air spaces (lacunae). These air cavities allow gases to circulate and provide buoyancy, helping aquatic plants (hydrophytes) float in water.
A: Food storage is the primary function of general parenchyma, not specialized aerenchyma. B: Water absorption is the specific function of root hairs or specialized xylem tissues, not air-filled aerenchyma. D: Mechanical strength is primarily provided by collenchyma and sclerenchyma tissues.
C is correct because Aerenchyma tissues are specifically adapted with large air pockets to provide buoyancy to aquatic plants, analogous to Chlorenchyma's role in photosynthesis.
In biology analogies, focus on the 'primary adaptation' of the tissue. If a term refers to a specific structural modification (like air spaces), the answer usually relates to the physical advantage that structure provides.
