Chapter 3 - Cells

Multiple Choice

This organelle uses glucose and other nutrients to provide energy for the cell.

• ribosomes
• nucleus
• mitochondria
• endoplasmic reticulum

Multiple Choice

The following organelle is made by the nucleolus and is used to make proteins.

• nucleus
• golgi apparatus
• cell membrane 
• ribosomes

Multiple Choice

This organelle can be either rough or smooth and acts as a pathway within the cell.

• endoplasmic reticulum
• cytoplasm
• ribosomes
• nucleus

Multiple Choice

This structure is made up of a bilayer of lipids and regulates which molecules can enter and leave the cell.

• cytoplasm
• nucleus
• cell membrane
• cell wall

Multiple Choice

Final processing or packaging of proteins occurs here before the proteins are released  from the cell.

• endoplasmic reticulum
• nucleus
• golgi apparatus
• cell membrane

Multiple Choice

This organelle gets rid of wastes or debris in the cell

• mitochondria

• lysosome

• endoplasmic reticulum

• Golgi apparatus

Multiple Choice

What is the diffusion of water only across a cell or semi-permeable membrane?

• Osmosis
• Diffusion
• Active Transport
• Passive Transport

Multiple Choice

In which case would a cell most likely shrink?

• when placed in a solution containing a high salt concentration
• when placed in a isotonic solution
• when placed in a solution containing a low pH
• when placed in a solution containing distilled water

Multiple Choice

Active transport requires energy because...

• The cell is moving something against a concentration gradient
• The cell is moving something with a concentration gradient

Multiple Choice

Endocytosis and Exocytosis are examples of...

• Active Transport
• Passive Transport

Multiple Choice

During diffusion

• substances (things) moves from high to low concentration
• water moves when energy is used
• large or oddly shaped molecules move across a cell membrane
• water moves from high to low concentration

Multiple Choice

Which stage of the cell cycle do cells spend the most time?

• Cytokinesis

• Mitosis

• Interphase

• Prophase

Multiple Choice

What is the last stage of the cell cycle?

• Cytokinisis

• Mitosis

• Miosis

• Anaphase

Multiple Choice

During interphase

• DNA lines up in the middle of the cell and DNA attaches to spindle fibers

• 2 new nuclei form

• 2 new identical cells are created

• DNA gets copied

Multiple Choice

Why do cells go through mitosis?

• to make food from sunlight

• to create proteins

• to get air into the cells

• to reproduce, grow and repair/replace

Multiple Choice

a cellular structure carrying genetic material, found in the nucleus. Consists of one long strand of DNA. 

• Chromosome
• ccentromere
• interphase
• sister chromatid

Multiple Choice

A cell that undergoes repeated mitosis without cytokinesis would have

• many daughter cells
• fewer chromosomes
• many nuclei
• cancerous properties

Multiple Choice

What is the function of embryonic stem cells?

• To produce insulin in the pancreas

• To become any specialised cell

• To carry oxygen through the blood system

• To maintain the body's tissues and organs
