Amoeba

Amoeba Pseudopodia: cytoplasm extensions Aids in locomotion (movement) Helps capture food (endocytosis)

Amoeba Contractile Vacuole: Regulates the amount of water within the cell by expelling excess. Helps maintain homestasis.

Amoeba Amoeba feeding

Paramecium Lysosomes Cilia Micronucleus Food Vacuole Macronucleus Cilia Micronucleus Food Vacuole Contractile Vacuole Anal Pore Oral Groove Trichocysts

Paramecium Mode of locomotion (movement)? Cilia Which structure helps them regulate the amount of water in the cell? Contractile Vacuole (maintains homeostasis)

Paramecium Paramecium expelling water

Euglena Contractile Vacuole Nucleus Chloroplast Eyespot Flagella

Euglena Mode of locomotion (movement)? Eyespot: Flagella Eyespot: Detects sunlight for photosynthesis. Which structure indicates euglena are autotrophic? Chloroplasts because photosynthesis occurs there.

Phototaxis: Movement of an organism in response to light. Positive phototaxis: move toward light Negative phototaxis: move away from light

Euglena Euglena!
