Rokes Cells

smallest unit of life that can perform all life processes; cells are covered by membrane and have DNA and cytoplasm Cell
anything that causes a reaction or change in a organism or any part of a organism Stimulus
maintenance of a constant internal state in changing environment homeostasis
reproduction in which cells from two parents unite, producing offspring that share traits from both parents sexual reproduction
reproduction that does not involve union of sex cells and in which one parent produces offspring identical to itself asexual reproduction
passing of genetic traits from parent to offspring heredity
sum of all chemical processes that occur in a organism metabolism
organism that can make its own food by using energy from its surroundings producer
organisms that eats other organisms or organic matter consumer
an organism that gets energy by breaking down the remains of dead organisms or animal wastes and consuming or absorbing the nutrients decomposer
molecule that is made up of amino acids and that is needed to build and repair body structures and to regulate processes in the body protein
class of energy giving nutrients that includes sugars, starches, and fiber; contains carbon, hydrogen, and oxygen carbohydrate
type of biochemical that does not dissolve in water; fats and steroids are lipids Lipid
a lipid that contains phosphorus and that is a structural component in cell membranes Phospholipid
Adenosine triphosphate a molecule that acts as the main energy source fro cell processes ATP
molecule made up of units called nucleotides Nucleic acid
most of the chemical reactions involved in metabolism require? water
air is a mixture of gases, oxygen and carbon dioxide
compounds that make up proteins amino acids
proteins that speed up chemical reactions enzymes
molecules made up of different kinds of atoms are compounds
the major energy carrying molecule in a cell is ATP
molecules consisting of subunits called nucleotides are called nucleic acid
how long can humans survive without water 3 days
what are four basic needs for every organism water, air, food, and a place to live
green plants, algae and some bacteria need carbon dioxide gas in addition to oxygen
cells of most living things are made of approximately 70% water
energy giving nutrients such as sugars starches and fiber are called carbohydrates
which is not true about lipids lipids mix with water
the molecules that form much of the cell membrane are phospholipid
carbohydrates made of one sugar molecule or few linked sugar molecules are called simple carbohdyrates
