Question

how are kelp holdfasts similar to proper root systems?
○ anchor parts to stable positions
○ use photosynthesis
○ carry water to the body
○ carry nutrients from the body
question 2

what term refers to various kinds of trees and shrubs that grow in saline coastal sediment habitats in the tropics and subtropics?
○ polychaetes
○ mangrove
○ sargassum
○ tunicates

Explanation:

Question 1

Kelp holdfasts function to anchor kelp to the ocean floor, and proper root systems anchor plants in the soil. Photosynthesis is done by leaves/chloroplast - containing parts, not holdfasts or roots. Roots absorb water and nutrients, while holdfasts don't carry water or nutrients like roots (roots carry nutrients from soil, not from the body). So the similarity is anchoring.

Polychaetes are a class of annelid worms. Mangroves are trees and shrubs that grow in saline coastal sediment in tropics/subtropics. Sargassum is a type of seaweed. Tunicates are marine invertebrates. So the correct term is mangrove.

Answer:

A. anchor parts to stable positions
