Chapter 6 Test Cells Form C Basic

Front

What is the function of lysosomes in a cell?

Back

Lysosomes act as the cell's waste disposal system, breaking down unwanted materials and recycling cellular components.

Front

What are the main components of the cell membrane?

Back

The cell membrane is primarily composed of phospholipids, which form a bilayer, along with proteins, cholesterol, and carbohydrates.

Front

What type of cells are cork cells?

Back

Cork cells are plant cells that are part of the bark of trees and are known for their protective properties.

Front

What organelle is found only in plant cells and is responsible for photosynthesis?

Back

Chloroplasts are the organelles found only in plant cells that convert light energy into chemical energy through photosynthesis.

Front

What is the role of the Golgi apparatus in a cell?

Back

The Golgi apparatus modifies, sorts, and packages macromolecules such as proteins and lipids for secretion or delivery to other organelles.

Front

What is the structure of a phospholipid?

Back

A phospholipid consists of a hydrophilic (water-attracting) 'head' and two hydrophobic (water-repelling) 'tails', forming a bilayer in cell membranes.

Front

How do lysosomes maintain cellular health?

Back

Lysosomes maintain cellular health by digesting excess or worn-out organelles, food particles, and engulfed viruses or bacteria.

Front

What is the significance of the chloroplast in plant cells?

Back

Chloroplasts are essential for photosynthesis, allowing plants to convert sunlight into energy and produce oxygen as a byproduct.

Front

Describe the process of protein modification in the Golgi apparatus.

Back

In the Golgi apparatus, proteins are modified by adding carbohydrate groups, folding into their functional shapes, and being sorted for transport.

Front

What is the difference between plant and animal cells regarding organelles?

Back

Plant cells contain chloroplasts and a cell wall, while animal cells do not; animal cells have lysosomes that are less prominent in plant cells.
