Summary Introduction
Introduction: Animals are multicellular eukaryotes and have heterotrophic (ingest food and digest them by certain digestive enzymes) mode of nutrition. They lack cell wall and the cells are connected to each other with the help of the collagen (extracellular matrix) and various structural proteins located outside the cell membrane. Animals have highly developed sensory and nervous systems.

What genus of protists appears to contradict the statement that unicellularity restricts cell size? a. Dictyostelium b. Ulva c. Plasmodium d. Caulerpa
Which of the following statement(s) is/are TRUE?
a. yeasts are unicellular fungi
b. molds and mushrooms are filamentous fungi. The filaments are chains of cells called "hyphae"
C. most protozoa are unicellular, animal-like members of Domain Archaea, many of which are motile
and lack cell walls
d. algae have historically been described as "plant-like" protists because they contain chloroplasts
and cell walls
e. organisms which make chlorophyll a can perform oxygenic photosynthesis
f. all organisms which make chlorophyll a have chloroplasts
g. Nostoc, algae and plants all make chlorophyll a and all have chloroplasts
h. Nostoc, algae and plants have mitochondria which evolved from primitive endosymbiotic bacteria
i. Photoautotrophs perform photosynthesis and chemoheterotrophs require pre-formed organic
molecules as a source of carbon and energy
j. Cyanobacteria, algae and plants are photoautotrophs. Fungi, protozoa and animals are
chemoheterotrophs
k. Most bacteria, all fungi, all algae…
