the concentration of sense organs, nervous control, etc., at the anterior end of the body, forming a head and brain, both during evolution and in the course of an embryo’s development.

Sessile

Answer 18

Not a free
moving organism.
Stays in one spot,
attached to a base.

Symmetry and Lifestyle Notes

Answer 22

Many radial animals are sessile or planktonic
and need to meet the environment equally well
from all sides.

Symmetry and Lifestyle Notes 2

Answer 23

Animals that move actively are bilateral, such
that the head end is usually first to encounter
food, danger, and other stimuli.

an animal embryo at the early stage of development when it is a hollow ball of cells.

Question 37

Purpose of Body Cavity

Answer 37

fluid cushions the internal organs, fluid of the body cavity can function as a hydrostatic skeleton against which muscles can work, enables the internal organs to grow and move independently of the outer body wall.
