look up bacillarophyta on wiki. these were some of the first organisms to live on earth.

Is centric diatom algae?
Yes, centric diatom are algae that are species that display radial symmetry. Diatoms are like clams, they have a two-part silica cell wall, called frustules. Diatoms are then divided into two groups based on the symmetry of their frustules, bilaterally symmetrical are called pennate diatom and centric diarom are radial symmetrical.
What's the difference between a pennate and a centric diatom?
one lives in salt water and the other in fresh water.
Which group diatoms can move around the best?
Most diatoms are non-motile, simply being carried by currents and turbulence - however, some types move via flagellation (the swimming motion of small hair-like features called 'flagella'). Flagella are projections from the cell body which are moved back and forth (flagellated) to provide motion. Identical in structure to flagella (but somewhat shorter in length), cilia are present in mammals primarily to facilitate the movement of fluids and mucus across tissues/membranes.
A muscle in which the fibers are arranged at an angle to a central longitudinal tendon has a arrangement?
Pennate.
Which diatoms can move around the best?
pennate diatoms

Is the infraspinatus a pennate fiber arrangement?
yes
What kind of pennate muscle is the vastus intermedius?
Strap
Is the adductor magnus a parallel or pennate muscle?
parallel
What is a pennate muscle?
Pennate MusclesIn a pennate muscle, the fascicles form a common angle with the tendon. Because the muscle cells pull at an angle, contracting pennate muscles do not move their tendons as far as parallel muscles do. But a pennate muscle contains more muscle fibers--and, as a result, produces more tension--than does a parallel muscle of the same size. (Tension production is proportional to the number of contracting sarcomeres; the more muscle fibers, the more myofibrils and sarcomeres.)
What are the pennate muscles of the human body?
deltoid gastrocnemius rectus femorus
Is the adductor longus parallel or pennate?
parallel
A muscle in which the fibers are arranged at an angle to a central longitudinal tendon has a arrangement?
Pennate.
