Plant and animal cells have many similarities in structure and function, however plant cells have three organelles that animal cells do not. Which of the following identifies a process that a plant cell is able to complete due to one of the additional organelles?

• Make its own food.

• Make new cells and reproduce.

• Ward off predatory organisms.

• Generate energy for processes in the cell.

Which of the following best explains why both plants and animals cells have mitochondria?

• The sugar is created in the mitochondria by both animal and plant cells.

• The sugar found in the food they both eat is broken down by the mitochondria in animal and plant cells.

• The sugar formed from photosynthesis is broken down by the mitochondria in the animal cell, and the sugar plants get from the food they eat is broken down by the mitochondria in the cell.

• The sugar formed from photosynthesis is broken down by the mitochondria in the plant cell, and the sugar animals get from the food they eat is broken by the mitochondria in the animal cell.

Which statement below best describes a cell structure found in plants and NOT in animal cells?

• This cell structure supplies energy to the cell.

• This cell structure pads and supports organelle inside the cell.

• This cell structure allows for materials to move in and out of the cell.

• This cell structure is made of cellulose to protect and support the cell.

You and your classmate are discussing different organs and organ systems within the human body. Your friend states that the excretory system includes multiple organs, and one of those organs is the lungs. You argue that the lungs can’t possibly be in the excretory system since it is part of the respiratory system. Which of the following choices would be the best statement that your friend would use to justify why the lungs help keep homeostasis for the excretory system?

• The lungs bring in oxygen, which is a vital gas to keep our cells alive and healthy.

• The lungs exhale carbon dioxide, which is a waste gas and needs to be removed from the body.

• The lungs provide cells with a gas that is important for the cell process of respiration.

• The lungs remove waste in the forms of solids, liquids, and gases that could be harmful for the body.

How do your respiratory and circulatory systems attempt to maintain homeostasis during exercise?

•  Your body produces more red blood cells to help provide energy to cells.

• Your lungs produce more oxygen which is then delivered to the cells through the blood.

• You experience an increase in blood flow which provides nutrients to cells to increase energy and remove wastes.

• You experience an increase in breathing rate to obtain more oxygen which is delivered to cells through the bloodstream.

Food gives the body energy, which helps the body maintain homeostasis. In the morning, an athlete eats a nutritious breakfast to get energy to exercise. What are the main organ systems involved in the process of food from the athlete’s breakfast being broken down into nutrients and then delivered to the cells?

• Digestive and excretory systems.

• Digestive and circulatory systems.

• Nervous and excretory systems.

• Respiratory and circulatory systems.

In order to maintain homeostasis, the systems of the human body work together to keep a constant internal temperature. Which of the following best describes how the human body responds in a cold environment?

• The digestive system produces more hormones to warm the body.

• The nervous system signals the muscles of the muscular system to contract and warm the body.

• The circulatory system delivers less carbon dioxide to the muscular system, resulting in stiffening of the muscles.

• The skeletal system produces more blood cells that circulate through the blood vessels, increasing the warmth of the body.

Which of the following processes is unique to plant cells due to the presence of chloroplasts?

• Photosynthesis

• Cellular respiration

• Protein synthesis

• DNA replication
