Bio 112 Exam Questions and Verified Answers/Accurate Solutions| Already Graded A+
Binary fission A form of asexual reproduction in single-celled organisms by which one cell
divides into two identical cells of the same size
cell membrane thin, flexible barrier around a cell; regulates what enters and leaves the cell
Centriole organelle structure in an animal cell that helps to organize cell division
Chloroplast organelle found in cells of plants and some other organisms that captures the
energy from sunlight and converts it into chemical energy
cytoplasm A jellylike fluid inside the cell in which the organelles are suspended
Diffusion Movement of molecules from an area of higher concentration to an area of lower
concentration.
Endoplasmic Reticulum A cell structure that forms a maze of passageways in which proteins
and other materials are carried from one part of the cell to another.
histone protein molecule around which DNA is tightly coiled in chromatin
nuclear envelope layer of two membranes that surrounds the nucleus of a cell
nuclear pores holes in the nuclear envelope that allow materials to pass in and out of the
nucleus
ATP (adenosine triphosphate) compound used by cells to store and release energy
, cell wall strong, supporting layer around the cell membrane in some cells
chromatin substance found in eukaryotic chromosomes that consists of DNA tightly coiled
around histones
Facilitated Diffusion process of diffusion in which molecules pass across the membrane with
the help of a protein channel or transporter but no ATP is required. Goes with the
concentration gradient.
Golgi apparatus organelle in cells that modifies, sorts, and packages proteins and other
materials from the endoplasmic reticulum for storage in the cell or release outside the cell
lipid bilayer flexible double-layered sheet that makes up the cell membrane and forms a
barrier between the cell and its surroundings
lysosome cell organelle that breaks down lipids, carbohydrates, and proteins into small
molecules that can used by the rest of the cell
Mitochondria cell organelles that convert the chemical energy stored in food into
compounds that are more convenient for the cell to use
nucleolus small structure found in the cell nucleus containing protein and nucleic acids
nucleus in cells, structure that contains the cell's genetic material in the form of DNA
Organelle specialized structure that performs important cellular functions within a
eukaryotic cell
osmosis diffusion of water through a selectively permeable membrane
