Lesson 1: Animal Cells, Tissues & Organ System Flashcards
Animal cells are _________ cells.
eukaryotic
Most genetic material is contained in prominent _________.
nucleus
Animal cells lack a _________.
cell wall
The thin flexible cell membrane that forms the outer boundary of each cell wall.
Cell Wall
__________ and other internal structures provide a division other than labor and allows the cells to work much more efficiently.
Organelles
Functions of mitochondria, ribosomes, vacuoles, and lysosomes.
Mitochondria functions as energy factories
Ribosomes functions as protein factories
Vacuoles serves as storage containers
Lysosomes serves as cellular digestion
Where does aerobic respiration happen?
inside the mitochondria
Function of protein
structure
movement
nerve impulses
metabolism
Single celled organisms like protozoa are ___________
Jack of all trades
___________ is considered as jack of all trades
Animal Tissues
(di ako sure if tama)
In multicellular organisms such as animals, the large size and complexity of dictates that individual cells __________ rather than performing all task.
Specialize
Group of similar cells performing similar functions.
Tissues
4 Basically Animal Tissues
- Epithelial
- Connective
- Muscular
- Nervous
The most primitive animal tissue
(presumably the first true animal tissue to evolve)
Epithelial Tissue
It forms the outer covering of animals.
Epithelial Tissue
Function of Epithelial Tissue
PAT FGS
- Protection from microbes, physical injury, water loss, etc.
- Absorption of food, water, etc in the intestine.
- Transport cilia
- Filtration in kidneys
- Gas Exchange lungs
- Secretion
The most widespread and abundant type of tissue in animals.
Connective Tissue
Connective tissues have an abundance of __________.
Matrix
a unique “animal” protein
Connective tissue fibers composed mainly of these.
collagens
Functions of Connective Tissue
GSN TT
- Glue in areolar tissue
- Support and Movement in bone & cartilage
- **Nutrient Storage ** in bone and adipose
- Temperature Homeostasis fat for heat production and cold insulation
- Transport blood, lymph
Elongated cells, spindled shaped, up to 1 ft long = muscle fibers.
Muscle Tissue
Functions of Muscle Tissue
- Movement (voluntary & involuntary)
- Posture
- Heat Generation for movement
Tissue that conducts impulses to send signals throughout the body.
Nervous Tissue
Function of Nervous System
- To sense internal and external environmental changes.
- Coordination and Control of muscles and glands.
Most adults retains some kind of “embryonic cells” called __________.
Stem Cells
What are the Animal (including Human) Organ Systems
SSMDRC ENS ER
- Skin (Integumentary System)
- Skeletal System
- Muscular System
- Digestive System
- Respiratory System
- Circulatory System
- Endocrine System
- Nervous System
- Senses
- Excretory System
- Reproductive System
The outer covering of animals.
Largest organ of the body
Skin (Integumentary System)
Cells that produce color in animals
Chromatophores
3 Main Kinds ode to Support System in Animals
- Exoskeleton
- Endoskeleton
- Hydrostatic Skeleton
A type of skeleton where muscles of body wall contain fluid pressure.
Hydrostatic Skeleton
Function of Skeleton
Support
Movement
Protection
Function of Muscular System
- Movement
- Heat Production
The major connection between external and internal environment.
Circulatory System
Kinds of Nervous System
Nerve Net
Ganglia and Nerve Cords
True Brain and Spinal Cord
Two Major Subdivision of nervous System
CNS and PNS
It monitors and allow organisms to respond to its environment
The Senses
sensory receptors are _______
transducers
Kinds of transducers
Photoreceptor - light
Chemoreceptor - chemicals
Thermoreceptor - temperature
Nocioreceptor (to injure) - pain
Osmoreceptor - water/salt concentration
Mechanoreceptor - bending, pressure, touch
