Explanation:
Answer:
Plant-like:
presence of flagella
shows the absence of cell wall, though chloroplast may be present
Animal-like:
absence of cell wall, as well as chloroplast
Fungus-like:
feeds on decaying matter
enclosed by a membrane called a pellicle
slime mold belongs in this category
Explanation:
The protists can be classified into three groups (plant-like, animal-like, fungus-like) based on the method of nutrition, movement, and mode of reproduction.
Plant-like protists have chloroplasts and trapped sunlight to form food ad energy (photosynthesis). They also have flagella used for the movement.
Example: Algae
Animal-like protists are heterotrophs that cannot make their food. They do not have chloroplast and cell wall outside the cell membrane.
Example: Protozoa
Fungus-like protists are single-cell eukaryotes that have a protective layer outside the cell membrane called pellicle. They feed on decaying organic matter.
Example: Slime mold and water mold
Answer: Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.
