The phylum Echinodermata , which contains about 6000 species, gets its name from the Greek, literally meaning "spiny skin." Many echinoderms actually do have "spiny" skin, but others do not. This phylum exists exclusively in the sea, and cannot be found on land or in fresh water. All echinoderms have one thing in common: radial symmetry. This means that the creatures have appendages (or body construction) which point outward from the center of the body like the spokes on a bicycle wheel. Furthermore, these appendages usually occur in multiples of five, although there are a few exceptions. There are several well known members of this group, like sea stars and sea urchins. The radial symmetry is obvious in these creatures.
Answer and Explanation:
Most young roots have two main regions. An outer cortex and a central cylinder containing the vascular bundles.
The endodermis also referred to as starch sheath. Its cells have a casparian strip which is made up of an impervious waxy deposit on the radial and cross walls. It controls entry of water and dissolved salts into the vascular bundle.
