Three things of the cell theory |
1. all living things are made of cell 2. cells are the basic units of structure and function 3. new cells are produced from existing cells
|
|
|
Structure and function of Cytoplasm |
jelly like material inside the cell, fills the empty space
|
|
|
Structure and function of nuclear envelope |
surrounds the nucleus, allows material in and out of the nucleus (proteins and RNA) |
|
|
Structure and function of the nucleolus |
small dense region in the nucleus, where production of ribosomes begin |
|
|
Structure and function of the nucleus |
contains DNA with the coded instructions for proteins and other important molecules |
|
|
Structure and function of chromatin |
granular material in the nucleus
|
|
|
Structure and function of chromosomes |
chromatin condenses to form chromosomes
|
|
|
Structure and function of ribosomes |
proteins are assembled here, small particles of RNA and protein found within the cytoplasm |
|
|
Structure and function of the endoplasmic reticulum
(Rough and smooth ER) |
rough er: where lipid components of the cell membrane are assembled, along with proteins and other molecules for export, abundant in cells that need lots of protein
smooth er: contains enzymes that perform specialized tasks like synthesis of membrane lipids or detoxifying
|
|
|
Structure and function of the golgi apparatus |
modify, sort, and package proteins from the er for storage or secretion
|
|
|
Structure and function of lysosomes |
small organelles filled with enzymes for breaking down lipids, or breaking down useless organelles
|
|
|
Structure and function of vacuoles |
store materials, water, salts, proteins, and carbohydrates
|
|
|
Structure and function of mitochondria |
think of tumblr: MITOCHONDRIA ARE THE POWERHOUSE OF THE CELL ;)
convert chemical energy stored in food into compounds easier to use
|
|
|
Structure and function of chloroplasts |
capture energy from sunlight and convert it into chemical energy
|
|
|
Structure and function of the cytoskeleton |
network of protein filaments that help maintain shape and movement, microfilaments and microtubules
|
|
|
Structure and function of the cell membrane |
regulates what enters and leaves the cell, protection, and support, made of lipid bilayer with carbs, and proteins |
|
|
Structure and function of the cell wall |
provides support and protection
ONLY IN PLANT CELLS |
|

What is Nathans middle name? |
Jerome |
|
|
what is a prokaryote? |
a cell without a nucleus |
|
|
What is a Eukaryote? |
A cell with a nucleus |
|
|
What is concentration? |
the mass of a substance in a given volume mass/volume |
|
|
What is diffusion? |
particles move from an area of high concentration to an area of low concentration
|
|
|
what is osmosis? |
diffusion of water through a selectively permeable membrane
|
|
|
What is the difference between hypertonic, hypotonic and isotonic? |
hypertonic: above strength, solution has higher solute concentration than the cell: water out
hypotonic: below strength, solution has lower solute concentration than the cell, water in
isotonic: same strength, concentration same inside and out |
|
|
What is equilibrium? |
Concentration of the solute is the same |
|
|
What is facilitated diffusion? |
cell membrane channels help diffusion across the membrane, protein channels
|
|
|
What is Shaina's favorite food that starts with an S? |
SUSHI. DUH |
