Study Notes

Compound Microscope Structure

The microscope has three main parts: eyepiece, body tube, and arm
The eyepiece has a magnification of 10x
There are three objective lenses: scanning, low, and high
Total magnification is calculated by multiplying the eyepiece magnification by the objective lens magnification

Cell Classification

Cells with a nucleus are eukaryotic (plants, animals, fungi, and protists)
Cells without a nucleus are prokaryotic (bacteria and archaeans)

Animal Cells

Three main parts of an animal cell: cell membrane, cytoplasm, and nucleus
Cell membrane controls what enters and leaves the cell
Cytoplasm is a liquid where chemical reactions occur
Nucleus is the control center of the cell

Plant Cells

Have additional parts compared to animal cells: cell wall, vacuole, and chloroplasts
Cell wall provides a fixed shape and support
Vacuole contains cell sap, which keeps the cell firm
Chloroplasts contain chlorophyll, which enables photosynthesis

Cell Organelles

Cytoplasm is a jelly-like material where chemical reactions occur
Nucleus contains genetic material and controls the cell's activities
Cell membrane is selectively permeable and controls the movement of substances
Chloroplasts contain chlorophyll for photosynthesis
Mitochondria are the site of energy release during respiration
Ribosomes are responsible for protein synthesis
Cell wall provides support and is made of cellulose fibers
