Organismal Biology Flashcards
Organismal Biology:
Mode of Reproduction
Sexual and Asexual Reproduction
Organismal Biology:
Mode of Reproduction:
1. Mode of reproduction that includes gametes.
Sexual Reproduction
Organismal Biology:
Mode of Reproduction:
1. Mode of reproduction that only involves one organism and does not use gametes.
Asexual Reproduction
Organismal Biology:
Mode of Reproduction
Asexual Reproduction:
1. Producing an individual through the buds that develop on the parent body.
Budding
Organismal Biology:
Mode of Reproduction
Asexual Reproduction:
1. Organism is capable of regrowing certain body parts.
Regeneration
Organismal Biology:
Mode of Reproduction
Asexual Reproduction:
1. Parent organism divides into fragments and each fragment develops into a new organism.
Fragmentation
Organismal Biology:
Mode of Reproduction
Asexual Reproduction:
1. A parent cell divided into two identical cells, each having the potential to grow to the size of the original cell.
Binary Fission
Organismal Biology:
Mode of Reproduction
Asexual Reproduction:
1. The development of an offspring by a female without a male to mate with.
Parthenogenesis
Organismal Biology:
Modes of Embryo Development
- Viviparous
- Oviparous
- Oviviparous
Organismal Biology:
Modes of Embryo Development:
1. Animals that give birth to offspring.
2. The development of embryo takes place inside the female reproductive system
Viviparous
Organismal Biology:
Modes of Embryo Development:
1. Animals that lay eggs
2. Fertilization takes place internally but embryo development takes place externally.
Oviparous
Organismal Biology:
Modes of Embryo Development:
1. Animals that lay eggs and develop eggs inside the mother’s body.
2. Possess embryos that develop inside eggs that remain in the mother’s body until they are ready to hatch.
Oviviparous
Organismal Biology:
Modes of Nutrition
Autotrophs and Heterotrophs
Organismal Biology:
Modes of Nutrition:
1. Organisms that are able to make their own food.
Autotrophs
Organismal Biology:
Modes of Nutrition
1. Organisms that gain energy from consuming other organisms.
Heterotrophs
Organismal Biology:
Modes of Nutrition:
Types of Heterotrophic Nutrition
- Parasitic
- Saphrophytic
- Holozoic
Organismal Biology:
Modes of Nutrition:
Types of Heterotrophic Nutrition:
1. Mode of heterotrophic nutrition where a parasitic organism lives on the body surface or inside the body of another type of organism (a host) and gets nutrition directly from the body of the host.
Parasitic
Organismal Biology:
Modes of Nutrition:
Types of Heterotrophic Nutrition:
1. Feed on dead and decayed organisms for energy.
Saphrophytic
Organismal Biology:
Modes of Nutrition:
Types of Heterotrophic Nutrition:
1. Involves the ingestion and internal processing of solid and liquid food in an organism.
Holozoic
Organismal Biology:
Modes of Nutrition:
Types of Heterotrophic Nutrition:
Types of Holozoic Nutrition
- Carnivore
- Omnivore
- Herbivore
Organismal Biology:
Modes of Nutrition:
Types of Heterotrophic Nutrition:
Types of Holozoic Nutrition:
1. Organism that feed on other animals for nutrition
Carnivore
Organismal Biology:
Modes of Nutrition:
Types of Heterotrophic Nutrition:
Types of Holozoic Nutrition:
1. Organism that depends on plants for nutrition.
Herbivore
Organismal Biology:
Modes of Nutrition:
Types of Heterotrophic Nutrition:
Types of Holozoic Nutrition:
1. Organisms that feed on plants and animals for nutrition.
Omnivore
Organismal Biology:
1. Animals that can produce their own body heat and don’t need to rely on the environment to regulate their body temperature.
2. Animals that maintain a constant body temperature by generating heat internally.
3. Examples: Mammals and Birds
Warm-Blooded Animals
Organismal Biology:
1. Animals that can’t produce their own body heat and need to rely on the environment to regulate their body temperature.
2. Animals that regulate their body temperature by exchanging heat with the environment.
3. Examples: Reptiles and Amphibians
Cold-Blooded Animals
Organismal Biology:
1. Animals that possess a backbone and an internal skeleton.
2. Does not have an exoskeleton
Vertebrates
Organismal Biology:
1. Animals that do not possess a backbone and an internal skeleton,
2. Have an exoskeleton
Invertebrates
Organismal Biology:
Body Symmetry
- Bilateral
- Radial
- Asymmetry
Organismal Biology:
Body Symmetry:
1. When the body plan can be divided along a plane that splits the animal’s body into right and left sides that are mirror images of each other.
Bilateral Symmetry
Organismal Biology:
Body Symmetry:
1. When the body are regularly arranged and radiate from a central point.
2. Can be equally divided into 3 or more sections from a common central axis.
Radial Symmetry
Organismal Biology:
Body Symmetry:
1. When no matter how you cut the body, the two halves will not be the same or identical.
Asymmetry
