(77 cards)
Common Characteristics
1, Multicellular Organism
2. Heterotroph
3. Sexual Reproduction
4. Development
5. Movement
6. Homeostasis
They must obtain complex organic material from other sources.
Heterotrophic
Most accomplish the process of heterotrophic
Ingestion
It is accomplished within animal. This process extracts the carbohydrates, protein, and lipids from the food eaten.
Digestion
Composed of many cells that are integrated and independent
Multicellular
Most animals contain
Large Number of Cells
These are the organization of cells.
Tissues
Production of a new organism from two parents by making of their sex cells or gametes.
Sexual Reproduction
In the process of Sexual Reproduction, male gametes fuses with a female gamete to form a new cell called
Zygote
It restores the diploid number and increases genetic variation
Sexual Reproduction
Production of a new organism from two parents by making use of their ________ or _______
Sex Cells or Gametes
During this process, the zygote undergoes many mitotic divisions.
Development
Is the process of cell becoming different from each other and being specialized
Differentiation
The ability to move results from the interrelations of two types of tissues found only in animals: Nervous Tissue and Muscular Tissue
Movemet
refers to an organism that is permanently attached to a surface and does not move from place to place.
Sessile
Relatively stable state inside the animal body.
Homeostasis
Keep the body in dynamic equilibrium by constantly adjusting the changes that the body systems encounter.
Homeostasis
Water Content
Osmoregulation
Temperature
Thermoregulation
An input stimulus causes an output response that “feeds back” to the initial input and decreases its effects.
Negative Feedback
Heating mechanisms activated
Shivering
Cooling Mechanisms Activated
Sweating
Produces a response that intensifies the original change.
Positive Feedback
Consistent overall pattern of structure of an animal
Symmetry
