Questions and Answers

Match the subcellular structure with its function:

Nucleus = Contains genetic material in the form of chromosomes that controls the cell's activities Cytoplasm = Gel-like substance where all the chemical reactions occur in the cells Mitochondria = Powerhouse of the cell where cellular respiration takes place Ribosomes = Site where the production of proteins takes place in the cell

Match the organelle with its description:

Chloroplast = Contains a green substance called chlorophyll used for photosynthesis Vacuole = Contains cell sap which inflates the cell Cell membrane = Holds the cell together and controls what goes in and out by providing a selective barrier Cell wall = Made up of cellulose and makes the cell wall rigid for support

Match the type of DNA with its location:

Chromosomal DNA = Contains genetic material and flows in the cell's cytoplasm Plasmid = Small loops of extra DNA used for drug resistance and can be passed between bacteria One long circular loop of DNA = Controls the cell’s activities and replication, floats free in the cytoplasm, not in a nucleus Chromosomes in the nucleus = Contain genetic material and control the cell's activities

Study Notes

Cell Structure and Function

Eukaryotic cells are large and complex, found in animals and plants, and have a subcellular structure with specific functions.
Prokaryotic cells are simpler and smaller, found in bacteria, and lack a true nucleus.

Subcellular Structure and Function

Nucleus: contains genetic material in the form of chromosomes, controlling the cell's activities.
Cytoplasm: gel-like substance where chemical reactions occur.
Mitochondria: powerhouse of the cell, site of cellular respiration, containing enzymes needed for the reaction.
Ribosomes: site of protein production in the cell.
Cell membrane: holds the cell together, controls what goes in and out, and provides a selective barrier with receptor molecules for cell communication.
Chloroplast: contains chlorophyll, used for photosynthesis.
Vacuole: contains cell sap, inflating the cell.
Cell wall: made of cellulose, making the cell wall rigid and providing support.

Prokaryotic Cell Features

DNA is a long, circular loop that controls the cell's activities and replication, floating free in the cytoplasm.
Chromosomal DNA: contains genetic material, flowing in the cell's cytoplasm.
Plasmid: small loops of extra DNA, used for drug resistance and can be passed between bacteria.

Microscopy

Microscopes use lenses to magnify images, increasing resolution and detail.
Light microscopes: invented in the 1590s, allowing us to see nuclei and chloroplasts.
Electron microscopes: invented in the 1930s, allowing us to see smaller structures like mitochondrial internal structure.
TEMs (Transmission Electron Microscopes): higher magnification and resolution than light microscopes, but not portable, expensive, and complicated to prepare specimens.
