| The rostellum ends in a holdfast by which the cell is fixed to the gut wall of its host. |
|
| At the base of the stalk is the holdfast, which cements the alga to the rock and prevents it from being washed away. |
|
| Recruitment to the harvest is not dependent on spore production since shoots arise vegetatively from the long-lived encrusting holdfast. |
|
| Attachment is achieved by flattening a sticky holdfast, which pulls the larva down on top of it. |
|
| Many aquatic bacteria produce an acidic mucopolysaccharide holdfast, which allows them to adhere tightly to rocks or other surfaces. |
|
| Recent changes by the industry in cutter rake design and maintenance have decreased the rate of holdfast removal. |
|
| Samples were taken from the harvest for holdfast analysis from each of the landing sites. |
|
| At the end of the holdfast is a tiny disc, which secretes an extremely powerful glue. |
|
| Figure 2: Diagrams of Chondrus crispus showing its discoid holdfast and Furcellaria lumbricalis showing its rhizoidal holdfast. |
|
| However, the majority of new shoots arise from basal holdfast tissues. |
|
| The specialized cell for attachment is called the holdfast. |
|
| They may lose the main body at the end of the growing season, but the attachment part, the holdfast, produces new growth only at the beginning of the next growing season. |
|
| In turbulent seas it breaks loose from its holdfast and moves offshore. |
|
| They are generally brown or dark green in color and consist of a holdfast, a stipe, and a frond. |
|
| It can be found attached to rocks at low tide with a branched holdfast. |
|
| In all species except A. americanum, the germinating radicle forms a holdfast when it contacts an obstruction on the host branch, such as a needle base. |
|
| Such fruits were tied with nylon fiber to the twigs of guava plants to allow the formation of the holdfast and the emergence of the haustorium. |
|
| In some Pasteuria strains, the daughter buds have a flagellum and are motile, whereas the mother cells lack flagella but have long pili and holdfast appendages at the end opposite the bud. |
|
| A wet, 10-square-centimeter surface slathered with holdfast could potentially hold about 70 tons, Tang says. |
|
| Round holdfast with wire blocking nib, body with two lateral screws. |
|
|
|
| The holdfast body is provided with an exagon for a simple wire blocking. |
|
| You can opt for a holdfast on a concrete pier or an augered pile. |
