Question

which of the following is not an adaptation for plants living in a lake/pond?○ sticky sap○ porous stems and leaves to absorb nutrients○ waxy coat to protect from drying out○ leaves that float on surface

Explanation:

• Porous stems/leaves help aquatic plants absorb dissolved nutrients from water.
• A waxy coat prevents floating aquatic plant leaves from drying out when exposed to air.
• Floating leaves allow aquatic plants to access sunlight for photosynthesis.
• Sticky sap is an adaptation for terrestrial plants (e.g., to deter herbivores or seal wounds), not for lake/pond plants.

Answer:

sticky sap
