Grade 10 Cell Biology Assessment

Which statement is part of the cell theory?
A cell has DNA but no membrane-bound nucleus. How should the cell be classified?
A cell needs to build a protein. Which structure directly joins amino acids to make the protein?
The ribosome
The Golgi apparatus
The mitochondrion
The lysosome
A cell makes a protein that must be packaged for transport. Which organelle performs this packaging?
The ribosome
The nucleus
The mitochondrion
A cell is placed in a solution with a lower solute concentration than its cytoplasm. Which way will water move by osmosis?
Out of the cell, toward the solution
Equally in both directions, with no net movement
Into the cell, toward the cytoplasm
Nowhere, because water cannot cross membranes
A membrane protein moves ions from low to high concentration. What is required for this transport?
Energy from ATP
Water moving through the membrane
A concentration gradient alone
No energy or membrane protein
Which organelle releases usable energy from food molecules during cellular respiration?
The Golgi apparatus
The mitochondrion
The chloroplast
The nucleus
A body cell divides to produce two genetically similar body cells. Which process is occurring?
Fertilization
Cellular respiration
Osmosis
Mitosis
A cell has many long extensions that increase its surface area for absorbing materials. What does this feature most likely show?
The cell is adapted for breaking down worn cell parts.
The cell is adapted for absorbing materials.
The cell is adapted for storing genetic information.
The cell is adapted for producing light energy.
