True

A gene is a subunit Of information within a chromosome

Isotonic

A water solution that has the same salt concentration as the cells is said to be

Cell wall

Cellulose

C6H12O6 O2 CO2 H2O Energy

Question 23

Ribosomes

The - are responsible for linking amino acids together

Meiosis

The division of the nucleus in reproductive cells is called

Semipermeable

The plasma membrane allows some molecular species to enter and excludes others. This is therefore referred to as - membrane

Proteins

The plasma membrane is made chemically of a molecule that has both polar and nonpolar ends and contains - inside its structure

A double layer of phospholipids

The plasma membrane is made up of

High

The relative concentration of water in a hypotonic solution is

When the molecules are insoluble

When is facilitated diffusion necessary

Osmosis

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

They are nonpolar and soluble

Why do O2 and CO2 pass through the plasma membrane

It will gain water and may burst

When an animal cell is placed in a hypotonic solution

Dependent on one another

All the organelles within the cell are interrelated and

Centrioles

Form fibers to separate chromosomes evenly

Cell wall

Gives strength to cell

Lysosome

Contain digestive enzymes

Endoplasmic Reticulum

Tubes serving as transportation channels

Nucleolus

Production of ribosomes

Golgi bodies

Production of secretions

Facilitated diffusion Passive diffusion Active transport Pinocytosis Phagocytosis

Question 15

Plasma membrane

Selective membrane

Plastids

Store food or pigments

Chromosomes

Contain genes for traits

False

It would appear logical that the first cell could have started to function from one organelle having formed by accident

Mitochondrion

Production of needed energy

Ribosomes

Production of protein

The basic unit of life is the cell

The cell theory teaches that

Mitochondria

Organelles that produce energy for the cell and ultimately the body are called

Plasma membrane

Phospholipid and protein

Nucleoli

Ribosomal RNA is produced by

False

Ribosomal RNA is produced in the cytoplasm

Pryuvic acid

Glycolysis ends in the production of

Adenosine diphosphate

The energy molecule ATP is a product of the reactant

The product of ATP decomposition

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

Active transport

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