It's alive! or is it?
8 - all of them
The two parts that are found in the nucleus or center of the atom.
Protons, Neutrons
All organic molecules contain this element
Carbon - C
Mitochondria
Cells without a nucleus, typically smaller too.
Prokaryotes
When something doesn't look alive but it is, like a seed or a hibernating animal.
Biotic - Dormant
Protons have _____ charge.
Electrons have _____ charge.
Neutrons have ______ charge.
Protons have positive charge.
Electrons have negative charge.
Neutrons have no/neutral charge.
This macromolecule is made by ribosomes and performs a variety of functions
Proteins
acts as a storage compartment for water, nutrients, and waste products
vacuoles
Genetic information is stored here in eukaryotic cells
Nucleus
When something is not alive and has never been alive.
Abiotic
Atomic number equals this in a neutrally charged atom.
Protons, electrons.
How all organisms create new macromolecules
rearranging atoms from food molecules
Modifies, sorts, and packages proteins and lipids for delivery.
Golgi Apparatus
Plants, animals, fungi, and even some single-celled organisms are this type of cell.
Eukaryotes
An old log in a forest, or a corpse that vultures feed on
biotic - dead
Oxygen (O) has an atomic number of 8, and an atomic mass of 15.999. How many protons in this element?
atomic number = number of protons
8
Glucose is a monosaccharide, a monomer to this macromolecule.
carbohydrates
gel-like, semi-fluid substance that fills the inside of a cell
cytoplasm
A student is trying to look at a cell with a microscope. The eyepiece is 10x magnification. The objective lens is 40x magnification. What is the total magnification?
10 x 40 = 400x
fire grows, "feeds" on grasses and trees for fuel, responds to the environment such as wind and rain. Is fire alive? explain.
No, does not have all 8 characteristics.
Sodium (Na) has an atomic number of 11, with an atomic mass of 22.990. How many neutrons in this element?
Atomic mass = protons + neutrons.
23 = 11 + neutrons
12 neutrons.
This macromolecule makes up the cell membrane, and has two different monomers. Name the macromolecule and its monomers.
Lipids - fatty acids and glycerols.
The two plant-specific organelles, one of which is where photosynthesis takes place.
Cell wall, chloroplasts
A new organism is found. It is a single cell, with genetic material floating inside the membrane. What type of cell is it?
Prokaryote - while both eukaryotes and prokaryotes can be single celled, no nucleus means prokaryotic cell.
