Starfish

Both bacteria and protists share processes such as reproduction, metabolism, growth, and response to stimuli. Additionally, they both possess genetic material in the form of DNA and have cell membranes that regulate the flow of substances in and out of the cell.

The blastula in sea star development is larger than the fertilized egg. As the zygote undergoes multiple rounds of cell division, it forms a hollow ball of cells called the blastula. This growth is accompanied by an increase in overall size.

Yes, in sea star development, the entire zygote is involved in early cleavage. Cleavage is a series of rapid cell divisions that leads to the formation of smaller cells called blastomeres. These early cleavage divisions help to increase the overall number of cells in the embryo.

Protists are made up of very large, diverse group of organisms, including the plant-like protists (algae), fungi-like protists, and the animal-like protists (protozoans). They are all eukaryotic, and most are unicellular.

Yes, each arm of a starfish contains a duplicate set of organs, including reproductive organs, digestive glands, and nerves. This duplication allows a starfish to regenerate lost arms since each arm has the potential to grow into a new, fully functioning starfish.

No, starfish are deuterostomes. They belong to a group of animals where the blastopore becomes the anus during embryonic development. This is opposed to protostomes, where the blastopore becomes the mouth.

One basic difference is their mode of nutrition: protists are typically single-celled organisms that can be autotrophic or heterotrophic, while fungi are multicellular organisms that are heterotrophic, meaning they obtain nutrients by absorbing them from their environment. Additionally, protists are usually motile, while fungi are mostly immotile.

The major difference between the protist and the animal kingdom is protists are unicellular protozoans and unicellular & multicellular, but animals are multicellular animals. For example, you could say protists are heterotrophs or autotrophs, and animals are only heterotrophs. However, animals such as sea anemones and coral can be both.

So, I would go with these three:

1. Multicellular animals, protists, single celled. However, there are some protists that are multicellular, like brown algae.

2. method of movement: protists - cilia, pseudopods, flagella.

animals, muscles and bones.

3. reproduction: animals mainly sexual with egg and sperm, protists binary fission.

Animal-like protists are eukaryotic organisms that exhibit characteristics typically associated with animals, such as mobility, heterotrophic nutrition, and complex cellular structures. They can move and capture prey like animals, showing similarities in behavior, diet, and cellular organization. However, unlike true animals, they lack specialized tissues and organs.

Protists are actually not animals; they are a diverse group of eukaryotic organisms that are not plants, fungi, or animals. They can be unicellular or multicellular, and they are known for their diverse habitats and modes of nutrition. Some protists are capable of photosynthesis, while others are heterotrophic.

The frog known for its sticky toes to help it climb tree limbs is called the tree frog. These frogs have specialized toe pads that secrete mucus to adhere to surfaces, allowing them to grip branches and climb with ease.

Yes protists are facinating and can live in almost every single biome in the world. All except for Antarctica

Sea stars do not sleep in the same way animals with brains do. They are known to be less active at night and may slow down their movements when resting. Sea stars are constantly filtering water and moving around even when they appear to be still.

That depends, obviously, on the species of Sea Urchin. All belong to the Phylum Echinodermata (along with sea stars and sea cucumbers) and to the Class Echinoidea. They are then divided into different orders, genera and species. That depends, obviously, on the species of Sea Urchin.

The armor of a grasshopper is an exoskeleton made of chitin, providing protection and support to its body. In contrast, a starfish does not have an exoskeleton but instead has a hard calcium carbonate skeleton underneath its skin, known as ossicles, for structural support.

Vorticella is a type of ciliated protozoan that can be found in freshwater environments. They are characterized by a bell-shaped body with a long stalk that attaches to substrates. Vorticella feed on bacteria and other small organisms by creating water currents with their cilia.

Yes, the tube feet of a living sea star move in coordination to help with locomotion, feeding, and attachment. The tube feet are connected to a water vascular system that controls their movement through hydraulic pressure. This allows the sea star to efficiently navigate its environment and capture prey.

A starfish is a free-moving animal. It can use its tube feet to move slowly along the ocean floor.

The coelomic cavity in a starfish functions primarily for circulation of nutrients, oxygen, and waste products throughout the body. It also houses the water vascular system, which helps in movement, feeding, and respiration by regulating water pressure in the tube feet.

Tube feet are a series of small tubular projections that can be find on all echinoderms, including the star fish. By pumping fluids in and out of these tubes, hydraulic pressure is created that can be used to grip onto a surface or circulate materials around the feet. In star fish, tube feet are often used as suction cups to keep a grip on the environment and prevent being swept away by undersea tides.

Starfish or sea stars are echinoderms belonging to the class Asteroidea. The names "starfish" and "sea star" essentially refer to members of the Class Asteroidea. However, common usage frequently finds "starfish" and "sea star" also applied to ophiuroids which are correctly referred to as "brittle stars" or "basket stars".

Protists are similar to bacteria in that they are both single-celled organisms. However, protists are eukaryotic, meaning they have a nucleus and other membrane-bound organelles, while bacteria are prokaryotic. Additionally, some protists are capable of photosynthesis like bacteria, but protists overall exhibit more complex cellular structures and functions.

No, not all protists have cell walls. Some protists have cell walls made of various materials like cellulose or silica, while others do not have cell walls at all. The presence or absence of a cell wall depends on the specific type of protist.

This depends on the organisms, but many things that live in the sea breathe through gills. There is oxygen in the water so they take in water and they will diffuse the oxygen out of the water into their cells.
