Question | Answer |
The __________ _________________ states cells come from pre-existing living cells. | cell theory |
Which macromolecule is made of sugars? | carbohydrates |
Which macromolecule is made of long chains of amino acids? | proteins |
This macromolecule does not dissolve in water making it a great substance for cell membranes. | lipids |
Macromolecules that from when long chains of nucleotides join together are called ____________ _________________. | nucleic acids |
DNA is arranged into _________________________. | chromosomes |
The main ingredient in cells is ____________________. | water |
Water is ideal for ______________ substances. | dissolving |
Main function of carbohydrates: | store energy, structural support, communication |
Nucleic acids contain __________________________. | genetic information. |
Vacuoles __________________ food, water, waste, etc. | store |
This organelle contains green pigments that absorb light energy. | chloroplasts |
What is the function of the Golgi apparatus? | package and distribute proteins |
Describe the differences between a plant and animal cell that you may see under a microscope. | animal: round, spread out, possibly bent/looking flexible plant: neatly organized rows, close together, visible cell wall and box shape |
These organelles make proteins and are found in eukaryotic and prokaryotic cells. | ribosomes |
A main difference between prokaryotic cells and eukaryotic cells is ____________________. | prokaryotic cells do not have a membrane surrounding their genetic information (no nulceus) eukaryotic cells have membrane bound DNA (nucleus) |
What is the function of the mitochondria? | To make energy for the cell by taking sugar (glucose) and turning it to ATP |
This organelle is found within the nucleus, and it creates ribosomes. | nucleolus |
gate system for the cell; semipermeable, controls what goes in and out of the cell | cell membrane |
rigid outer layer of plant cells | cell wall |
gel-like fluid where organelles are found | cytoplasm |
use chemicals to break down food and waste in the cell | lysosome |
stores materials for the cell; plants have 1 large of these organelles while animal cells have few, smaller ones | vacuole |
passageways to carry proteins/materials around the cell | endoplasmic reticulum (er) |
assembles proteins | ribosomes |
control center of the cell where genetic information is stored; found in eukaryotic cells | nucleus |
scientist who named cells | Robert Hooke |
scientists who studied plant and animal cells; they came to the conclusion that both types of cells share similar features | Schleiden & Schwann |
scientist who proposed "all cells come from pre-existing cells" | Virchow |
the three principles of the cell theory | 1. all living things are made of cells 2. the cell is the smallest unit of life 3. all cells come from pre-existing cells |
the pigment found inside chloroplasts | chlorophyll |
