characteristics of plant cells:

- cell plate and no centrioles in cell division - presence of cell wall plus plasma membrane - large hypertonic vacuole - chloroplasts and plastids

QUOTE five transport mechanisms of the cell:

- facilitated diffusion - passive diffusion - active transport - pinocytosis - phagocytosis

characteristics of an animal cell:

- no cell well, only plasma membrane - no large vacuole, only small ones - no chlorophyll or chloroplasts - cleavage furrow plus centrioles in cell division

all the organelles within a cell are

interrelated and dependent on one another

the plasma membrane allows some molecular species to enter and excludes others.

it is a semipermeable membrane

when an animal cell is placed in a hypotonic solution

it will gain water and may burst

Ribosomal RNA is produced by

nucleoli

mitochondria

organelles that produce energy for the cell and ultimately the body

when water moves freely from a membrane containing a higher concentration to a lower concentration, the diffusion is called

osmosis

phospholipid and protein, selective membrane

plasma membrane

Ribosomal RNA

produced in the cell's nucleus

mitochondrion

production of needed energy

ribosome

production of protein

nucleolus

production of ribosomes

Golgi bodies

production of secretions

the plasma membrane is made chemically of a molecule that has both polar and nonpolar ends and contains

proteins inside its structure

ribosomes

responsible for linking amino acids together

plastics

store foods or pigments

the cell theory teaches that

the basic unit of life is the cell

meiosis

the division of the nucleus in reproductive cells

Adenosine Diphosphate (ADP)

the energy molecule "ATP" is a product of the reactant

the energy required for the mechanism of "active transport" comes from:

the product of ATP decomposition

Why do O2 and CO2 pass through the plasma membrane?

they are nonpolar and soluble

endoplasmic reticulum

tubes serving as transportation channels

active transport

when the cell concentrates potassium within, against the natural tendency of matter, it is performing

when is facilitated diffusion necessary

when the molecules are insoluble

a gene is a subunit of information

within a chromosome

the relative concentration of water in a hypotonic solution is

high

chemical reaction within the mitochondrion

C₆H₁₂O₆ + O₂ -> CO₂ + H₂O+energy

cells are clear evidence of

a Creator with wisdom and foresight

the plasma membrane is made up of

a double layer of phospholipids

isotonic

a water solution that has the same salt concentration as the cells

cellulose and gives strength to the wall

cell wall

lysosomes

contain digestive enzymes

chromosomes

contain genes for traits

glycolysis

ends in the production of pyruvic acid

centrioles

form fibers to separate chromosomes evenly
