Cell Biology Basics Quiz

Study Notes

The speaker shares memories of exciting science classroom experiences, including observing an amoeba under a microscope.
Modern cell theory includes three main points: cells are the basic unit of life, all living things are made of cells, and all cells come from pre-existing cells.
Amoebas are single-celled organisms, while humans are multicellular.
Prokaryotes (like bacteria) have no nucleus or membrane-bound organelles, while eukaryotes (plants, animals, fungi, protists) have membrane-bound organelles.
The cell membrane is selectively permeable and keeps the cell stable.
Cytoplasm is a jelly-like substance found inside the cell, and cells have a cytoskeleton for support and movement.
Ribosomes, which make proteins, are not membrane-bound organelles.
In eukaryotes, the nucleus holds genetic material and controls cell activities, and the endoplasmic reticulum processes and transports molecules.
The Golgi apparatus packages and sorts molecules for secretion or transport to the membrane.
Mitochondria produce energy in the form of ATP through cellular respiration.
Plant cells can have additional organelles like chloroplasts, which make glucose through photosynthesis, and a cell wall for protection and shape maintenance.
Eukaryotic cells have various ways of sending proteins out of the cell, including vesicles from the Golgi apparatus.
