31 Questions
Where is the vascular cambium located and what is its function?
Located between xylem and phloem, increases plant's diameter
What is the primary function of apical meristem?
Responsible for plant's primary growth
What is the main function of cork cambium?
Acts as a protective layer
What does transpiration involve?
Loss of water vapor through stomata
What is the role of ground tissue in plants?
Functions as storage, support, and short-distance transport
Which type of meristem is responsible for increasing the girth/width of the plant as it grows?
Vascular cambium
What is the function of stomata in plants?
To regulate gas exchange
How does water move upward in plants?
As a result of negative pressure (tension) from transpiration
What is the role of the circulatory system in animals?
To transport nutrients and gases throughout the body
What protects the oxygen-rich blood from mixing with oxygen-poor blood in the heart?
Division of heart into 2 sides
Where does oxygenation of the blood occur in the circulatory system?
In the capillary beds
How does glucose move downward in plants?
Via active transport process called translocation
What is the main purpose of transpiration in plants?
To facilitate nutrient transport and photosynthesis
What happens to O2-poor blood after circulating throughout the body?
It returns to the lungs for oxygenation
What is role of pulmonary circulation in animals' circulatory system?
Pulmonary circulation oxygenates blood before it returns to heart.
Meristem is a collection of differentiated cells in plants.
False
The dermal tissue includes guard cells and root hair.
True
Vascular cambium lies between xylem and phloem and increases the plant's height.
False
Transpiration involves the loss of water vapor through stomata on the leaves.
True
Parenchyma, collenchyma, and scelerenchyma are examples of ground tissue in plants.
True
Cork cambium acts as a protective layer as the old and non-functioning xylem is pushed to the outermost layers.
False
Transpiration is an important process for the water cycle in plants.
True
Glucose moves downward in the phloem through a passive process called translocation.
False
Water moves upward in the xylem through a passive process of transpiration.
False
The circulatory system is used to transport nutrients and gases through the body of all animals.
True
The right side of the heart collects oxygen-rich blood and pumps it to the tissues through the aorta.
False
Pulmonary circulation involves the flow of blood away from the heart through the lungs, where oxygenation occurs.
True
Coronary circulation supplies oxygen to the tissues in the body.
True
Oxygen diffuses into the tissues as CO2 diffuses into the bloodstream in capillary beds.
True
In plants, transpiration creates a negative pressure that pulls water upward from the roots.
True
The division of heart into 2 sides prevents oxygen-rich blood from mixing with oxygen-poor blood.
True
Study Notes
Plant Structure and Function
- Vascular cambium is located between xylem and phloem and is responsible for increasing the plant's height.
- Apical meristem is responsible for increasing the length of the plant as it grows.
- Cork cambium acts as a protective layer, pushing old and non-functioning xylem to the outermost layers.
Plant Tissue
- Dermal tissue includes guard cells and root hair.
- Ground tissue in plants includes parenchyma, collenchyma, and sclerenchyma.
Plant Transport
- Transpiration involves the loss of water vapor through stomata on the leaves.
- Water moves upward in the xylem through a passive process of transpiration.
- Glucose moves downward in the phloem through a passive process called translocation.
Animal Circulatory System
- The circulatory system is used to transport nutrients and gases through the body of all animals.
- The right side of the heart collects oxygen-rich blood and pumps it to the tissues through the aorta.
- Pulmonary circulation involves the flow of blood away from the heart through the lungs, where oxygenation occurs.
- Coronary circulation supplies oxygen to the tissues in the body.
Heart Function
- The division of the heart into two sides prevents oxygen-rich blood from mixing with oxygen-poor blood.
- Oxygenation of the blood occurs in the lungs during pulmonary circulation.
- O2-poor blood returns to the heart after circulating throughout the body.
- In capillary beds, oxygen diffuses into the tissues as CO2 diffuses into the bloodstream.
