IB - The Cell Theory and Ultrastructures of Cell

Which structures are found in ALL cells?

• cell membrane and cytoplasm
• chloroplasts and mitochondria
• a cell wall and nucleus
• chloroplasts and cell wall

Which cell structure is found in plant and animals cells and controls what can come into or leave a cell?

• cell membrane
• cytoplasm
• nucleus
• vacuole

Chloroplasts in plant cells allow the plant to perform a function that animal cells cannot do.  What is the main function of the chloroplasts found in plant cells?

• to absorb light energy and manufacture food
• to remove waste materials by active transport
• to manufacture chemical energy from food
• to control the shape of the cell

All cells need energy to function.  Which cell organelle is responsible for producing energy in the cell?

• chloroplasts
• mitochondria
• nucleus
• vacuoles

What is the function of a cell wall?

• to protect and support the cell
• to perform different functions in each cell
• to prevent water from passing through it
• to prevent oxygen from entering the cell

Which organelle acts as the sorting/packaging centre of the cell?

• Nucleus
• Golgi Apparatus
• Chloroplasts
• Vacuoles

 What is the difference between the cell wall and the cell membrane?

• There is no difference
• The cell membrane is found ONLY in animal cells, whilst the cell wall is found ONLY in plant cells 
• The Cell wall is found ONLY in plant cells
• The cell wall is found ONLY in animal cells

Which of the following is NOT part of the CELL THEORY?

• Cells must contain DNA 
• All living things are made from cells
• Cells can only come from other cells
• Cells are the basic unit of life

What is the basic unit of all living things?

Where are proteins made?

• Golgi body
• Mitoichondria
• Chromosomes
• Ribosomes
