Study Notes
Characteristics of Living Things
- Living things grow in size, reproduce, and repair themselves
- Living things need energy
- Living things react to changes in their environment
- Living things have a lifespan
- Living things produce waste
Plant Growth
- Plants and animals grow larger as they age
- Plants make their own food using sunlight
- Plants can repair damaged parts
- Animals eat plants or other animals for energy
Living Things and the Environment
- Animals may escape predators or seek food
- Plants grow towards water
- Living things live, grow, and die.
- Living things release waste into the environment
Compound Microscopes
- Compound microscopes are used to view cells.
- Microscopes use lenses and light to magnify specimens.
- Magnification is how much larger a specimen appears.
- Field of view is the part of the specimen seen through the eyepiece.
Plant and Animal Cells
- Nucleus is the control center of a cell, containing genetic information
- Nucleus controls all the cell activities.
- Chromosomes carry instructions for the cell's functioning
- Plant cells have cell walls (support and protection)
- Plant cells contain chloroplasts (photosynthesis)
Cell Movement
- Flagella and cilia move animal cells.
- Flagella are tall structures.
- Cilia are hair-like projections.
