The document describes the structures of several types of cells: - Amoebas have pseudopods for movement, cytoplasm, a cell membrane, contractile and food vacuoles, and a nucleus. - Euglenas have a reservoir, nucleus, contractile vacuole, pellicle, chloroplast, nucleolus, and flagellum. - Parameciums have cilia, contractile and food vacuoles, micronucleus, oral groove, gullet, cytoplasm, and large nucleus. - Plant cells have a nucleus, chloroplasts, mitochondria, cytoplasm, vacuoles, and a cell wall.

2. Amoeba
Structure of an amoeba:
Pseudopod: part of the amoeba used for locomotion.
Cytoplasm: central part of an amoeba.
Cell membrane: membrane covering an amoeba.
Contractile vacuole: cavity of the amoeba that is able to contract.
Food vacuole: cavity of the amoeba responsible for digestion.
Nucleus: central organelle for an amoeba.
Digestive vacuole: cavity of the amoeba responsible for digestion.

3. Structure of a euglena: flagellate freshwater protozoan.
Reservoir: part of a euglena used for storage.
Nucleus: central organelle of a euglena.
Contractile vacuole: cavity of the euglena that is able to contract.
Pellicle: membrane that envelops a euglena.
Chloroplast: organelle of the euglena responsible for photosynthesis.
Nucleolus: spherical body that contains the nucleus of a euglena.
Stigma: light-sensitive part of a euglena.
Flagellum: long, mobile filament used by the euglena for locomotion.

4. Structure of a paramecium:
Cilia: minuscule cilia that envelop the paramecium and are used for locomotion.
Contractile vacuole: cavity of the paramecium that is able to contract.
Food vacuole: cavity of the paramecium responsible for digestion.
PARAMECIUM Micronucleus: one of the less important central organelles of a paramecium.
Oral groove: canal of the paramecium used to ingest nutrients.
Gullet: cavity of the pharynx.
Cytoplasm: central part of a paramecium.
Large nucleus: the most important central organelle of a paramecium.

5. Plant cell: the cell is a highly complex system that is the site of
intense energy exchange and which presents vast interphase
surfaces. Like all living organisms, it feeds itself, grows, multiplies and
Nucleus: small spherical body with the cell
Chloroplast: granule of chlorophyll, which is needed for
photosynthesis.
Mitochondria: granule that plays an important role in the respiration
and energy-releasing reactions in living cells.
Cytoplasm :liquid part of the cell
Vacuole: space with the cytoplasm of a cell containing various
substances.
Cell wall: rigid wall around the cell
