General Anatomy Flashcards
What are the basic tenets of Cell Theory?
- All living organisms are composed of cells.
- The cell is the basic unit of structure and organization in organisms.
- All cells come from pre-existing cells.
What are the Basic Processes of Life?
- Take in food and metabolize it for energy.
- Respond to the environment.
- Grow.
- Reproduce.
- Dispose of waste.
What are the 2 main types of cells?
Prokaryotes and Eukaryotes.
Prokaryotes are …… celled and are usually in the form of ……?
Single-Celled
Bacteria and algae
Eukaryotes are …… and tend to be ……..?
Single celled and multi-celled
Plants animals fungi and protists
Eukaryotes reproduce through?
Mitosis and Meiosis
Prokaryotic cells reproduce through?
Fission (budding)
Chloroplast is the …… where photosynthesis occurs. And all …. plant cells have it.
Site
Eukaryotic
What does the Nucleus do? And which type of cells have it?
Regulates all cell activity, including cell replication; does this through DNA.
All Eukaryotic Cells
Ribosomes job is to….? And which cells have them?
Use RNA to transcribe the original DNA code into proteins.
Both prokaryotic and eukaryotic cells.
Mitochondria are ….? All ….. cells have them.
Cell powerhouses; use oxygen to burn glucose and produce ATP for cell energy.
Eukaryotic
Cytoplasm is the…? All cells have this.
Watery medium inside of a cell.
Cytoskeleton provides …. for cells and allows …?
Structure, transport
What are the two types of Endoplasmic reticulum (ER)?
And what do they do?
Rough ER; has ribosomes and produces protein.
Smooth ER; used in synthesis of fats.
Cell membrane is the…?
Phospholipid bilayer that acts as a highly selective barrier for passive and active transport. (Bouncer)
Which cells have cell walls?
Prokaryotes plants and fungi
What do Golgi bodies do?
Package proteins.
Vacuoles are?
Storage containers
The Flagellum is for…?
Locomotion; the way cells move.
Building Blocks of Cells. 4 Steps.
- Cells
- Tissue
- Organ
- Organ system
4 main types of tissue include:
Connective tissue (bone and cartilage)
Muscle tissue (skeletal and cardiac muscles)
Nervous tissue (brain cells and spinal nerves)
Epithelial tissue (organ surfaces, mouth lining, and skin)
Examples of Organs include:
Heart, brain, stomach, and kidneys.
Organs and tissues join together to form?
Organ Systems
The 10 major systems in the human body are:
Respiratory system Cardiovascular system Gastrointestinal system Neuromuscular system Reproductive system Integumentary system Endocrine system Genitourinary system Immune system Skeletal system
