What do you think has become of Captain Hill and his companions, Mr. holdfast? |
Figure 2: Diagrams of Chondrus crispus showing its discoid holdfast and Furcellaria lumbricalis showing its rhizoidal holdfast. |
Many aquatic bacteria produce an acidic mucopolysaccharide holdfast, which allows them to adhere tightly to rocks or other surfaces. |
Samples were taken from the harvest for holdfast analysis from each of the landing sites. |
At the base of the stalk is the holdfast, which cements the alga to the rock and prevents it from being washed away. |
At the end of the holdfast is a tiny disc, which secretes an extremely powerful glue. |
