Eukaryotic Cells and Microorganisms Review

Evidence suggests that eukaryotic cells evolved from

• plant cells

• prokaryotic cells

• fungal cells

• spores

These eukaryotic organisms can be unicellular, but a few are colonial.

• helminths

• fungi

• protozoa

• algae

An external structure of the eukaryotic cell is the glycocalyx which include

• slime and capsule

• cell wall and cell membrane

• cilia and cell membrane

• slime and cell wall

These are similar to flagella in overall structure but shorter and more numerous.

(a)  

Rigid organelle that provides structural support and shape to the cell.

• cell membrane

• cytoskeleton

• cell wall

• cytoplasm

Which part of the eukaryotic cell is responsible for contacting the outside environment and signaling between cells?

• cell membrane

• flagella

• cell wall

• glycocalyx

Serves as selectively permeable barrier in transport.

(a)  

Identify the structure

(a)  

This organelle is responsible for intracellular digestion.

• vacuole

• lysosome

• mitochondria

• ribosome

This organelle is responsible for packaging and modification of proteins prior to secretion.

• Golgi apparatus

• Rough ER

• Smooth ER

• nucleolus
