Cell Unit Review

Front

What are the main components of the cell membrane?

Back

The cell membrane is primarily made of phospholipids and proteins.

Front

If a cell's cytoplasm has a higher concentration of calcium ions than the surrounding solution, in which direction will calcium ions move?

Back

Calcium ions will move out of the cell.

Front

What organelle in plant cells is responsible for converting sunlight into chemical energy?

Back

The chloroplast is responsible for converting sunlight into chemical energy.

Front

In which organelle is food broken down into energy in both plant and animal cells?

Back

Food is broken down into energy in the mitochondria.

Front

What type of cell has a nucleus but lacks chloroplasts and cell walls?

Back

This is an animal cell.

Front

Who studied animal cells and contributed to cell theory?

Back

Theodor Schwann studied animal cells.

Front

What is the function of lysosomes in a cell?

Back

Lysosomes are responsible for breaking down and getting rid of waste in a cell.

Front

What is the role of proteins in the cell membrane?

Back

Proteins serve various functions, including acting as channels, receptors, and enzymes.

Front

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

Back

Plant cells contain chloroplasts for photosynthesis, while animal cells do not.

Front

What is the significance of the fluid mosaic model in understanding cell membranes?

Back

The fluid mosaic model describes the structure of the cell membrane as a flexible layer of phospholipids with various proteins embedded, allowing for movement and interaction.
