What else can I help you with?
Some unicellular organisms are motile and some are nonmotile which cellular structures are associated with movement a flagella b chloroplast vacuoles d ribosomes?
A) flagella are cellular structures associated with movement in unicellular organisms. They are long, whip-like structures that help propel the organism through its environment. Vacuoles are membrane-bound sacs that store materials and assist with cell structure and shape. Ribosomes are involved in protein synthesis. Chloroplasts are organelles involved in photosynthesis and are typically found in plant cells.
How do most protosists move?
Most protists move using structures called flagella, cilia, or pseudopods. Flagella are long whip-like structures that propel the organism through its environment, cilia are short hair-like projections that beat back and forth to propel the organism, and pseudopods are temporary bulges of the cell membrane that extend and contract to move the organism.
What are short threadlike structures extending from cell membranes of protists?
Cilia and flagella are short threadlike structures extending from the cell membranes of protists. They are used for movement and/or feeding by creating a whipping motion to propel the organism through its environment.
Why don't unicellular organisms go through cellular differentiation?
Cellular differentiation is for cells that are to become specialized parts of a larger organism. Think along the lines of brain cells, skin cells, heart, cells, etc. Unicellular organisms are, by definition, a single-celled organism, and that is why they do not go through cellular differentiation.
What structure allow the paramecium to move?
Paramecium moves using hair-like structures called cilia. These cilia beat in a coordinated manner to propel the organism through its environment.
What structure does this organism use to move through its environment?
This organism uses cilia for movement. Cilia are hair-like structures on the surface of the cell that beat rhythmically to propel the organism through its environment.

How does oxygen get into a unicellular organism?
Oxygen can diffuse into a unicellular organism through its cell membrane. The organism utilizes this oxygen for cellular respiration to produce energy.

When a multi-cellular organism is cut the injury is repaired through the process of?
cell division
What are the two kinds of respiratoin?
The two kinds of respiration are cellular respiration and external respiration. Cellular respiration occurs within cells to produce energy, while external respiration involves the exchange of gases between an organism and its environment, typically through breathing.
How does an organism become more complex over time?
An organism becomes more complex over time through a process called evolution. This involves genetic changes that accumulate over generations, leading to the development of new traits and structures that increase the organism's complexity and adaptability to its environment.
What are short threadlike structures extending from cell membranes of protists?
Cilia and flagella are short threadlike structures extending from the cell membranes of protists. They are used for movement and/or feeding by creating a whipping motion to propel the organism through its environment.
Which structure would a unicellular organism MOST LIKELY have to move around?
A unicellular organism would most likely have flagella or cilia to move around. These structures are used for locomotion in single-celled organisms. Flagella are long, whip-like structures that propel the cell forward, while cilia are shorter, hair-like structures that help the cell move through its environment.
Where does an organism get its energy from?
Organisms obtain energy from their environment through sources like sunlight, organic matter, or inorganic compounds. This energy is used for various cellular processes such as growth, reproduction, and maintenance of biological functions.
What is the difference between unicellular organisms and a multi cellular organism?
some kind of mitosis that tgoes through
What is the term for structure that has no use in an organism?
Vestigial StructureA vestigial structure is a structure that appears to no longer have a use in the body.
