Prentice Hall Biology Chapter 10 Cell Growth And Division (2004)

organelles – subcellular structures; well-defined, intracellular structures that perform specific functions for the cell
cuticle waxy coat – a protective layer that protects it from losing water because the sun is strong.
Lipids or fats – Like carbohydrates made of CHO but a different ratio of H: O
Eg. Beef fat = C57 H11 O6 Note how many carbon atoms there are . 57 !!!!
The more Carbon atoms a molecule has the more energy rich it is. Fats are solid at room temp. Oils are liquid at room temp.
Foods high in lipids are oil, butter, cheese, nuts, olives.
Flagellum – A hair-like structure made up of microtubles that function in locomotion
diploid – cell with 2 of each chromosome type. (human's number is 46)
pH – the measure of how acidic or basic a solution is.
1. Mitogens
2. Growth factors
3. Survival factors – Extracellular molecules are soluble factors that are grouped into what three categories?
rRNA (ribosomal RNA) – type of RNA that makes up the major part of ribosomes
Weakness, darkening of skin, and loss of appetite were some of the signs and symptoms experienced by the patient diagnosed with a chronic syndrome resulting from a deficiency in the hormonal secretion of the adrenal cortex or
20.Fluid mosaic model – model that describes the arrangement and movement of the molecules that make up a cell membrane.
A ______________________ is an adaption that is related to a plants or animals FORM or STRUCTURE – Structural Adaption
pinnate venation – when a leaf's veins all branch out from the midrib, we say that the leaf has
polymer – A large molecule made up of many similar or identical subunits.
trace elements – elements required by an organism in only minute quantities
limbic system – A functional unit of several integrating and relay centers located deep in the human forebrain; interacts with the cerebral cortex in creating emotions and storing memories.
Weаkness, dаrkening оf skin, аnd lоss оf appetite were some of the signs and symptoms experienced by the patient diagnosed with a chronic syndrome resulting from a deficiency in the hormonal secretion of the adrenal cortex or
When individuals near the center of the curve have higher fitness than individuals at either end of the curve. Natural selection works with this norm. – Stablizing selection
The human chromosome number – 46
Organs – A specialized center of body function composed of several different types of tissues.
