A. may attach to rough endoplasmic reticulum
B. manufactures proteins
C. Often called protein factories
What is Ribosomes?
100
Doesn't require added energy and results in movement down the concentration gradient.
What is passive transport?
100
G1 - cell growth S - DNA synthesis occurs G2 - prepares for cell division
What is Interphase
100
Cytokinesis occurs
What is telophase I and telophase II
100
covers body and lines body cativites
cells packed close together
What is epithelial tissue
200
A. forms the outer boundary of the cell
B. Thin two layered membrane of phospholipids containing proteins
C. is selectively permeable
D. also contains fatty cholesterol
What is Plasma Membrane?
200
a liquid substance that is used to dissolve another substance.
What is solvent?
200
produces 2 identical daughter cells from parent cell.
What is mitosis.
200
Reduces by half
What is chromosomes?
200
Has 3 different types of tissue: Skeletal, Smooth, and Cardiac
What is Muscle Tissue?
300
paired organelles
lie at right angles to each other near the nucleus
function in cell reproduction
What is Centrioles
300
processes occur only in living cells, movement is up the concentration gradient, and requires energy from ATP.
What is active transport?
300
Chromotids align across the center of the cell. Spindle fibers attach themselves to each chromatid.
What is Metaphase?
300
number of division(s)
What is 2
300
Has 2 different cell types: neurons and glia.
What is Nervous Cells.
400
network of connecting sacs and canals
carry substances through the cytoplasm
What is Endoplasmic Reticulum (ER)
400
Movement of water from an area of high concentration to an area of low concentration.
What is osmosis?
400
Centromeres break apart. chromatids now called chromosomes and pulled to opposite ends of the cell.
What is anaphase
400
produces 4 daughter cells with half the chromosome # of parent cell.
What is Meiosis
400
This type of tissue is glue that holds organ together.
What is areolar?
500
group of flattened sacs near the nucleus
collect chemicals that move from the smooth er in vesicles
What is Golgi Apparatus/Golgi Body
500
movement of particles from an area of high concentration to an area of low concentration.
What is Diffusion?
500
Centrioles move away form the nucleus. nuclear envelope disappears. spindle fibers appear.
