Plants are characterized by having cellulose in their cell walls.

The kingdom Protista includes both autotrophic and heterotrophic organisms.

Annelida, or segmented worms, are characterized by their segmented bodies.

Echinoderms exhibit radial symmetry in their adult form, which is a defining characteristic of this phylum.

Nematodes, or roundworms, are characterized by a body covered with a cuticle and are unsegmented.

Phylum Porifera, which includes sponges, is characterized by a porous body structure.

Unsaturated hydrocarbons contain double or triple bonds, making them more reactive than saturated hydrocarbons.

Ethers are generally low in reactivity compared to alcohols and phenols, making them stable compounds.

Group 13 elements typically form covalent compounds due to their tendency to share electrons.

Halogens exist as diatomic molecules (e.g., Cl2, F2) in their elemental form.

Noble gases are colorless and odorless under standard conditions.

Phenols undergo halogenation readily due to the electron-donating effect of the hydroxyl group.

Phosphorus exists in several allotropes, including red, black, and white phosphorus.
