Figure 1.3 is a drawing of the bacterium Vibrio cholerae, the pathogen that causes the disease "cholera". State 3 structural differences of V. cholerae that are not found in animal cells.

Figure 1.1 is a diagram of an electron micrograph of a plant cell. Figure 1.2 is a diagram of an electron micrograph of an animal cell. Both cell diagrams are incomplete.

Explain how Figure 1.1 can be identified as a plant cell.

The nucleolus manufactures ________ RNA

Ribosomes synthesize ________ (_______ synthesis)

Vacuole functions

• stores water, sugar, pigment

• exports protein

Lysosomes function

• involved in cell recognition

• contains enzymes

Centrioles, cilia, microtubules, and microvilli are structures found in eukaryotic cells. Which statement about these structures is true?

• Centrioles, cilia, and microvilli are all composed of microtubules

• Centrioles play a role in mitosis and semi-conservative DNA replication.

• Cilia and microvilli both increase the Surface Area for absorption.

• Microtubules are made of protein and form the spindle in Mitosis.

Answer explanation

Although cilia and centrioles are composed of microtubules, microvilli are not

Centrioles only play a role in mitosis, they do not play a direct role in semi-conservative DNA replication

Microvilli increase the surface area for absorption, cilia function is movement
