Answer:

Here are the 3 structures:-

Explanation:

The three structures that various protozoa may use for locomotion are:

Flagella: long, whip-like appendages that propel the protozoa by rotating or undulating.

Cilia: short, hair-like projections that cover the surface of the protozoa and move in a coordinated manner to create a current or a wave.

Pseudopodia: temporary extensions of the cytoplasm that push or pull the protozoa by changing shape and direction.

Final answer:

Protozoa use different structures for locomotion including flagella, cilia, and pseudopodia. Flagella are whip-like structures that some protozoa use to move around. Cilia are shorter and more numerous, aiding in movement and food collection. Pseudopodia, 'false feet', are temporary cell projections used for movement.

Explanation:

Various protozoa use different structures for locomotion, which allows them to move around their environment. Three primary structures used for movement include:

1. Flagella: These are whip-like structures that extend from the cell body. Some protozoa, such as the Giardia lamblia, use this flagellum to propel themselves.
2. Cilia: Shorter and more numerous than flagella, cilia cover the surface of certain protozoa like Paramecium, aiding in its movement and food capture.
3. Pseudopodia: Literally meaning 'false feet', these are temporary projections of the cell. Amoeboid protozoa, such as Amoeba, use pseudopodia to move by extending a part of their body forward and pulling the rest of the body toward it.

Answer: Carolus Linnaeus

Explanation:

The formal system of classification was introduced by a Swiss scientist named Carolus Linnaeus.

He first split living things into a general category called KINGDOM.

- The kingdom is further split into large smaller groups called PHYLUM (for animals) and DIVISION (for plants).

- Each phylum or division is broken down into CLASSES.

- Each class is broken down into ORDERS

- Orders into FAMILIES,

- Families into GENUS

- Genus into SPECIES

Thus, the linnaean system of classification from highest (most general category) to the lowest level is as follows: Kingdom --> phylum/division --> class --> order --> family --> genus --> species.
