Which statement is true about the organelles that make food for eukaryotic plant and animal cells?

• The mitochondria make food for animals cells, and the nucleus makes food for plant cells.

  
  

  
  

  
  
  

• The mitochondria make food for plant cells, and the nucleus makes food for animal cells.

  
  

• he chloroplasts make food for animal cells, but plant cells cannot make their own food.

• The chloroplasts make food for plant cells, but animal cells cannot make their own food.

How do the structures of a vacuole and a nucleus differ?

• A vacuole is enclosed within a membrane, and a nucleus is not.

• A vacuole contains mostly DNA, and a nucleus contains mostly water.

• A vacuole contains mostly water, and a nucleus contains mostly DNA.

• A vacuole is a thick fluid, and a nucleus is a rigid set of layers.

A group of students was asked to explain how one organelle in a cell directly supports the work of another organelle to maintain cellular homeostasis within a plant cell. 

 

Which of the following students offers the BEST explanation?

• Student 1: Chloroplasts and mitochondria benefit from breaking down proteins for immediate energy.

• Student 2: Mitochondria produce energy molecules, which are digested by the lysosomes to provide energy for cellular processes.

• Student 3: Chloroplasts convert solar energy into simple sugars, which are then used by the mitochondria to provide energy for the cell.

• Student 4: Golgi Bodies sort and package lipids used by the smooth ER to make proteins.

What function do ribosomes have within a cell?

• Ribosomes produce ATP.

• 
  Ribosomes synthesize proteins.

• Ribosomes contain genetic material.

• Ribosomes control what enters and exits the cell.

  
  

What is the term for the body's ability to maintain a stable internal balance?

• Peristalsis

• Metabolism

• Homeostasis

• Physiology

In what part of the cell is food energy converted for cellular use?

• Cell wall

• Nucleus

• Mitochondria

• Flagellum

If a cell is compared to a city, then the lysosomes act as which of the following?

• trash service of the cell as it removes waste from the cell

• post office of the cell by packaging and sorting proteins

• mayor of the cell as it controls all of the cell's activities

• electrical plant of a cell by making usable energy

Which of the following are NOT found in both plant and animal eukaryotic cells?

• Vacuoles

• Chloroplasts

• Mitochondria

• Nuclei

Which of the following explains the cellular function of a ribosome?

• It is associated with attaching to the plasma membrane in active transport.

• It is directly involved in the bonding of amino acids to synthesize proteins. 

• It is associated with microtubules and microfilaments to move organelles. 

• It is directly involved in the storage of energy by converting ADP to ATP. 

When compared to prokaryotic cells, eukaryotic cells ___. 

• are simple, smaller, and have DNA floating freely throughout the cell.

• are complicated, larger, and have DNA captured in a membrane-bound structure.

• are round and hard, unlike rectangular and soft prokaryotic cells.

• are able to move from place to place, unlike stationary prokaryotic cells.
