the Pomacentridae or damselfish family that live in tropical marine waters throughout the world. They are home loving creatures and live amongst the tentacles of sea anemones in the shallow waters of coral reefs. Sea anemones are members of the phylum Cnidaria. They have stinging tentacles with specialized organelles called nematocysts

are either scenario questions or art questions‚ which typically involve higher-order thinking. Among these are two new sets of scenario questions‚ each devoted to a single-species animal phylum. The first pertains to the (possibly) basal animal known as Trichoplax‚ and the second to the bizarre phylum found only on lobster lips‚ the Cycliophora. Multiple-Choice Questions 1) Both animals and fungi are heterotrophic. What distinguishes animal heterotrophy from fungal heterotrophy

to mosses (Phylum Bryophyta)‚ the vascular plant sporophyte is dominant over AND is functionally independent of the gametophyte. • Conductive (vascular) tissues are universal AND are present in the sporophyte (not the gametophyte). • Although mosses live in moist environments (at least some of the time)‚ some vascular plants have acquired relative independence of free water. • Some vascular plants survive in harsh conditions (including hot and cool deserts). Ferns belong to the Phylum Pterophyta

photosynthetic‚ plants found in the biosphere Most are autotrophs (synthesize own food with help of solar energy) Contains about billion types of plant species Based on biologists‚ plants are divided into four main groups: 1. Phylum Bryophyta 2. Phylum Pteridophytae 3. Phylum Angiosperms 4. Phylum Gymnosperms These four main groups were classified based on: The presence/absence of vascular tissues (xylem and phloem; transport of nutrients) The presence/absence of seeds Two types of plants 1.

20.1 KEY CONCEPT-Plant life began in the water and became adapted to land. Plants are multicellular eukaryotes‚ most of which produce their own food through photosynthesis and have adapted to life on land. Plants share many characteristics with green algae. Both are photosynthetic eukaryotes with the same types of chlorophyll. Both also use starch as a storage product and have cell walls that contain cellulose. One ancient species of green algae is the common ancestor of all plants. If it were

DISCUSSION Bryophytes are seedless plants without specialized water conducting tissues. Bryophytes include mosses (phylumBryophyta)‚ liverworts (phylum Marchantiophyta Hepatophyta)‚ and hornworts (phylum Anthocerophyta). They are plants that virtually everyone has seen‚ but many have ignored. The most commonly encountered group is the green mosses that cover rotting logs‚ anchor to the bark of trees‚ and grow in the spray of waterfalls‚ along streams and in bogs. Even though mosses often thrive in
