Scientists and Cells
The scientist who first gave cells their name.
Who is Robert Hooke?
This organelle contains DNA, and controls cell division.
What is the nucleus?
This part of a cell maintains homeostasis by controlling what enters and leaves the cell through its phospholipic bilayer.
What is the cell membrane?
This type of cell has a nucleus and other membrane bound organelles. Animals, plants, and fungi along with other multicellular organisms have this type of cell.
What is a eukaryotic cell?
The power of magnification that Anton van Leeuwenhoek's best microscopes had was...
What is 400x
This is the first person who saw living cells using a microscope.
Who was Anton van Leewenhoek?
This organelle is the janitor of the cell, cleaning up wastes and recycling them, also destroying invading viruses and bacteria, breaking down excess microtubules.
What is a lysosome?
This organelle is found in plant cells but not animal cells, and contains chlorophyll which is instrumental in performing photosynthesis.
What is a chloroplast?
This type of cell does have a cell wall, but lacks a nucleus or other types of membrane bound organelles.
What is a prokaryotic cell?
The microscopes that we use in school are the kind that scientists used to make many of the advancements in biology in the last 200 years. This microscope is called...
What is the compound light microscope?
Robert Hooke was a member of the Royal Society and invented a microscope through which he observed these, which he thought looked like the rooms monks lived in.
What are cork cells?
This organelle constructs proteins for the cell.
What is a ribosome?
The smooth version of this produces lipids and phospholipids that form the cell membrane. It can also help to neutralize toxins that enter the cell.
What is the endoplasmic reticulum?
Both Eukaryotic and Prokaryotic cells have this structure that maintains homeostasis by being semipermeable.
What is a cell membrane?
What advantage does the type of microscope we use in school have over electron microscopes even though they cannot magnify objects as much?
What is they can be used to study living cells?
A certain Dutch draper constructed lenses for examining his cloth. He figured out how to use his lenses as a microscope which could magnify images this much.
What is 400x?
This organelle stores cell materials and in plants supplies turgor pressure.
What is a vacuole?
The cytoskeleton provides structure to cells and is composed of these two things.
What are microtubules and microfilaments?
Both Eukaryotic and Prokaryotic cells use this type of molecule to encode genetic information that produces the necessary information for protein sythesis.
What is DNA?
Microscopes were instrumental in discovering the structure of cell membranes. The main reason the cell membrane can successfully maintain homeostasis inside cells is...
What is the phospholipid bilayer that has a polar head on both sides that attracts water and fatty-acid tails in the center that repel water.?
Name the Scientist most responsible for Cell Theory and state Cell theory.
Robert Virchow helped discover that all organisms are composed of cells. Cells are the basic unit of structure and function of all living things. Cells only come from other cells and carry genetic information that they pass on to their daughter cells.
This organelle acts as a distribution center for cell proteins, packaging them and delivering them where they are needed.
What is the Golgi Apparatus?
Single celled protozoa often have these organelles that cover their surface and propel them through the water.
What are cilia?
Both types of cells use passive transport. Describe the 3 types of passive transport.
What are diffusion, facilitated diffusion, and osmosis?
Microscopes allow us to see both active and passive transport. The two ways that cells achieve active transport are...
What are proton pumps and Endocytosis and exocytosis?
