What are the six characteristics of life?
The six characteristics of life include:
* organization
* metabolism
* responsiveness
* growth
* development
* reproduction
These characteristics define living organisms and differentiate them from non-living entities.
Define homeostasis.
The ability to maintain stable internal conditions.
Homeostasis is crucial for the survival of organisms and involves various physiological processes.
What are passive transports?
Processes that move substances across the plasma membrane without the use of energy, relying on concentration gradients.
Includes diffusion, facilitated diffusion, and osmosis.
Name three types of passive transport.
- Diffusion
- Facilitated diffusion
- Osmosis
These processes do not require energy input.
What is the primary function of mitochondria?
Known as the powerhouse of the cell, where ATP is produced.
Mitochondria are essential for cellular respiration and energy production.
Fill in the blank: Mitochondria are known as the _______ of the cell.
[powerhouse]
What is ATP?
Adenosine triphosphate, the energy currency of the cell.
ATP is produced in mitochondria during cellular respiration.
What does DNA stand for?
Deoxyribonucleic acid
DNA carries the genetic instructions for all known living organisms and many viruses.
What is the primary function of DNA?
Carries genetic instructions for growth, development, functioning, and reproduction
This applies to all known living organisms and many viruses.
What are the two predominant lipids in the plasma membrane?
Phospholipids and cholesterol
These lipids play critical roles in maintaining the structure and function of the plasma membrane.
List the four primary tissue types.
- Epithelial
- Connective
- Muscle
- Nervous
These tissue types are essential for the organization and function of organs and systems in the body.
