The Cell Block
The basic unit of life from which every living organism is built
(What is a cell?)
Formed by a group of cells, this level of organization sits directly below an organ.
(What is tissue?)
The molecule of inheritance that carries genetic material from parent to offspring
(What is DNA or deoxyribonucleic acid?)
The sum of all chemical reactions where substances are broken down or built up to power life.
(What is metabolism?)
The maintenance of constant, stable internal conditions despite external changes.
(What is homeostasis?)
This term describes a single-celled organism, which is usually microscopic.
(What is unicellular?)
The heart, lungs, and stomach are examples of this level of organization
(What is an organ?)
In this type of reproduction, cells from two parents unite to create genetically distinct offspring
(What is sexual reproduction?)
The primary energy carrier molecule that stores and releases energy inside cells.
(What is ATP?)
This type of feedback loop counteracts a change to restore the body back to its normal baseline.
(What is negative feedback?)
Complex organisms are made of these types of cells, which are complex and differentiated.
(What is multicellular?)
This level is formed by multiple organs working together to support life processes.
(What is an organ system?)
This type of reproduction features a single parent producing offspring genetically identical to itself.
(What is asexual reproduction?)
The process where plants capture sunlight and convert it into chemical energy.
(What is photosynthesis?)
This type of feedback loop amplifies a response, driving a biological process to completion.
(What is positive feedback?)
The process where cells specialize to perform specific tasks, like nerve cells transmitting signals
(What is cell differentiation?)
Defined as anything that has mass and takes up space, it flows through all biological levels
(What is matter?)
Bacteria, plants, fungi, protists, and these organisms are the five groups your notes list that study biology.
(What is animals?)
Inherited traits that give an advantage to individual organisms and are passed to future generations.
(What is an adaptation?)
The hormone released during childbirth that intensifies uterine contractions.
(What is oxytocin?)
True or False: Cells grow, divide, and repair throughout an organism's life.
(What is True?)
A living thing made of one or more cells, sitting at the top of this lesson's organization hierarchy.
(What is an organism?)
Fill in the blank: Reproduction is the process where organisms transmit genetic material to their _______.
(What is offspring?)
This mechanism drives evolution because individuals with favorable traits survive and reproduce more successfully.
(What is natural selection?)
This system lowers your blood sugar back to normal when levels rise
(What is negative feedback using insulin?)
