Prokaryotic and Eukaryotic Cells
What be the difference between em? and give an example of each or I will kill you
Eukaryotic Cells have a membrane enclosed nucleus and procaryotic cells have a non membrane-enclosed nucleoid.
Procaryotic- simple cells like bacteria
Eukaryotic- plant cells and animal cells
What is lysosome? and which cell has it?
Unique to animal cells- digestive
What are peroxisomes?
Specialized metabolic compartment bounded by a single membrane that contain enzymes that remove hydrogen from things and transfers them to oxygen-making H2O2 (hydrogen peroxide)
What are peripheral proteins?
a type of membrane protein that are loosely attached to the surface of cell membranes, rather than being embedded within them-maintains cells shape and aids in signaling.
What is the cytoskeleton?
Reinforces the cells shape
What is chlorplast and which cell has it, cupcake?
PLANT CELLS OBVIOUSLY and it converts energy to sunlight
What on earth are microtubules?
Well, apparently, they are hollow rods in eukaryotic cells that aid in the cells movement.
What is diffusion?
Spontaneous movement of a substance down its concentration gradient.
What is the Endoplasmic Reticulum
What be chromosomes?
Within the nucleus and carry genetic information.
What the hell are cilia and centrioles?
What is osmosis?
Water diffuses out through the permeable membrane of a cell.
What are ribosomes?
Complexes that make protein, baby. Free ribosomes float around like rubber ducks in cytosol and bound ribosomes are attached to the ER
What is the difference between the smooth ER and the Rough ER
Rough Endoplasmic Reticulum (RER) has ribosomes on its surface, giving it a rough appearance, and is involved in protein synthesis and modification, while the Smooth Endoplasmic Reticulum (SER) lacks ribosomes and is responsible for lipid synthesis, detoxification, and calcium storage
What are the three types of cell junctions in animal tissues?
Tight, desmomosomes, and gap
What is exocytosis?
What be the Golgi Apparatus (this is a goofy name!)
Synthesis, modification, sorting, and secretion of cell products. Sorting center like the POST OFFICE
WHAT IS THE MITOCHONDRIA
Well, it's the site of cellular respiration, the metabolic process that uses oxygen to general ATP by extracting energy from sugar (I love sugar) and from fats (don't be rude)
Who is your favorite family member?
IT'S ME!
OKAY! WHAT IS THE DIFFERNCE BETWEEN ACTIVE AND PASSIVE TRANSPORT?
active transport requires cellular energy (like ATP) to move substances against their concentration gradient, while passive transport does not require energy and moves substances down their concentration gradient (from high to low concentration)
