Biology Term 2
| Question | Answer |
|---|---|
| Digestive Juices | Acids that break down swallowed food, makes nutrients avalible |
| Peristalsis | Involuntary muscle contraction that propels food to stomach |
| Lower Esophageal Sphincter | What food passes through at the end of esophagus, which relaxes and lets food in stomach |
| Villi | Finger-like projections that increase SA |
| SA | Surface area, more of it means more surfaces for nutrients to absorb in bloodstream |
| Adipose tissue | Connective tissue (ex. fat droplets) |
| Atom | Combo of protons, neutrons, electrons, fundamental particle of matte |
| Blood | Connective tissue (ex. red blood cells) |
| Bone | Connective tissue, holds body together (skeleton) |
| Cartilage | Connective tissue, holds body together at the end of bones |
| Cellular differentiation | Unspecialized cell turns into specialized cell |
| Colony | Organised group of unicellular organisms |
| Connective tissue | Holds body together/protects from infections |
| Cuticle | Protective layer on plant surface (non-cellular) |
| Epidermis | Surface layer of plant/animal cells, protects organism from environment |
| Epithelial tissue | Cells lining internal/external surfaces (blood vessels, airways, digestive organs |
| Fibrous connective tissue | Connective tissue holding body together (ex. Tendon forming) |
| Loose connective tissue | Connective tissue holding body together, under skin |
| Meristem | Area of plant tissue where cells divide to form new tissues (tips of roots/stems) |
| Mitosis | Nuclear division, maintains parental number of chromosomes for daughter cells (basis of bodily growth and asexual reproduction in some eukaryotes) |
| Multicellular | Organism w/ more than one cell |
| Muscle Tissue | Tissue made of muscle fibres that contract at stimulation |
| Nervous tissue | Tissue containing cells specialized for transmission of nerve impulses |
| Neuron | Nerve cell |
| Organ | Group of different tissue types that work together to perform certain functions |
| Root hair | Tube-like outgrowth of a root epidermal cell that increases root’s SA, absorbs water/nutrients |
| Specialization | Having special features linking to a specific purpose |
| Specialized cell | Cell w/ features suited to its purpose |
| Stem cell | Unspecialized cell that can transform into different specialized differentiated cells |
| System | Group of organs working to carry out a function |
