Glowing Squids??

Originating from the Greek bios for “living” and the Latin lumen “light”, Bio luminescence is the ability for an organism to produce and emit light. This trait is common among Squids. In fact, 63 out of the 100 genres contain species with this capability. Some squids use a bioluminescent bacteria or bioluminescent chemical mixtures like they would use ink. They expel this chemical mixture to repel predators and to make a hasty escape.

The Bobtail Squid is a bit different. Bobtail squid have a symbiotic relationship with bioluminescent bacteria, which inhabit a special light organ in the squid’s mantle.. It’s bioluminescent bacteria are fed sugar and amino Acid and in return hide the squid’s silhouettes when viewed from below by matching the amount of light hitting the top of the mantle.

Hydra: Movement and Locomotion

If a Hydra is alarmed or attacked, it’s tentacles can be retracted to small buds, and the body column itself can be retracted to a small gelatinous sphere. This happens when a Hydra is exposed to any sort of stimulus like the liver that we put in.This stimulation causes the hydra to take a defensive position and or move around. A Hydra can possibly move around 100 mm. This is an example of Structure and Function. The Hydra’s body and tentacles are structured so that it can move and assume this defensive position

CELL PAINTING

My Favorite Organelle

My favorite organelle is the Nucleus. The Nucleus is a very important part of the cell. It stores the DNA which is like a blueprint for the body, and chromosomes which are long stands of DNA jammed into a cylinder like object. It seems really cool and interesting. I like that it is universally important and universally known.
