Plant and Animal Cells Quiz

What organelles are found in a plant cell and not an animal cell?

• Chloroplast

• Cell wall

• Cell Membrane

• Nucleus

Answer explanation

Plant cells contain chloroplasts for photosynthesis and a cell wall for structure and support, which are not found in animal cells. Therefore, both chloroplasts and cell walls are unique to plant cells.

Name the function of each organelle listed in the chart below.

(a)  

Answer explanation

The nucleus controls cell activities, mitochondria provide energy, the cell membrane regulates entry and exit, the cell wall offers protection, vacuoles store substances, and chloroplasts perform photosynthesis to create glucose.

What happens to the appearance of the size of the cells as you move from low to high power?

Answer explanation

As you move from low to high power, the cells appear larger. This is due to the increased magnification, allowing for a more detailed view of the cell structure.

Define unicellular and multicellular.

(a)  

Answer explanation

Unicellular organisms consist of a single cell, while multicellular organisms are composed of multiple cells. The definitions provided correctly describe these two types of organisms.

Are rocks considered living? Explain.

Answer explanation

Rocks are not considered living because they do not exhibit characteristics of life, such as growth, reproduction, or response to stimuli. They are inanimate objects formed through geological processes.

Define: Diffusion

(a)  

Answer explanation

Diffusion is the process where materials move from an area of higher concentration to an area of lower concentration until equilibrium is achieved. This definition accurately describes the concept of diffusion.

Define: Osmosis

(a)  

Answer explanation

Osmosis is the diffusion of water across a selectively permeable membrane. It involves the movement of water from an area of lower solute concentration to an area of higher solute concentration, balancing concentrations on both sides.

If corn syrup was placed on the outside of a plant cell, would corn syrup move into the plant cell? Why or why not?

Answer explanation

Corn syrup is hypertonic compared to the plant cell's cytoplasm. Water would move out of the cell to balance the concentration, preventing corn syrup from entering the cell.

During interphase the DNA will duplicate itself and grow. This will prepare the cell for cell division. How many daughter cells are made if a skin cell divides?

(a)  

Answer explanation

When a skin cell divides during mitosis, it produces 2 daughter cells. The correct answer is 2, not 0, as each division results in two identical cells.

Explain how healing takes place in the skin that has been deep enough to bleed. Include the cells in the blood that are helpful in your explanation.

Answer explanation

Healing begins with blood clotting, where platelets and white blood cells (like neutrophils and macrophages) prevent infection and clear debris. Fibroblasts then produce collagen, forming new tissue, while epithelial cells regenerate the skin surface.
