Movement

: the act or process of moving people or things from one place or position to another

Organelles found in eukaryotic cells

Eukaryotic cells contain many membrane-bound organelles. An organelle is an organized and specialized structure within a living cell. The organelles include the nucleus, ribosomes, endoplasmic reticulum, Golgi apparatus, vacuoles, lysosomes, mitochondria, and, in plants, chloroplasts

characteristics of living things

Control, metabolism, reproduction, responsiveness, growth, education, evolution.

Membrane

cell membrane that keeps the pieces inside. When you think about a membrane, imagine it is like a big plastic bag with some tiny holes. That bag holds all of the cell pieces and fluids inside the cell and keeps any nasty things outside the cell. The holes are there to let some things move in and out of the cell.

• What Are the 7 Characteristics of Living Things?

o Living things have a complex, organized structure that consists largely of organic molecules. o Living things respond to stimuli from their environment. o Living things actively maintain their complex structure and their internal environment, a process called homeostasis. o Living things acquire and use materials and energy from their environment and convert them into different forms. o Living things grow. o Living things reproduce themselves, using a molecular blueprint called DNA. o Living things, as a whole, have the capacity to evolve.

Evolution

populations changing overtime evolution is a slow change in the genetic makeup of the population rather than an individual that enables it to survive in its environment

Complex, organize and structure

• The combination of components can form a more complex organization called a system. ° Examples of biological systems are cells, organisms, and ecosystems.

Adaptability

Adaptation for the physical address it's organismic all relatively long periods of time to change in in their environments.

The cell concept

All living organisms are composed of one or more cells. The cell is the basic unit of structure and organization in organisms. Cells come from preexisting cells.

Reproduce

An essential aspect of life cells go through binary fission tonproduce two identical daughter cells

Growth

Growth refers to a positive change in size, and/or maturation, often over a period of time. Growth can occur as a stage of ...

Heredity

Heredity is the passing of phenotypic traits from parents to their offspring, either through asexual reproduction or sexual reproduction. This is the process by which an offspring cell or organism acquires or becomes predisposed to the characteristics of its parent cell or organism.

Technique used to search for life on other planets

Jeff in and Paul Butler use indirect evidence of planets around the star to find new planets. Do use of telescope networks to find planets. Aracibo Observatory, the planned terrestrial planet finder,

maintain complex and organized structure

Living things actively maintain their complex structure and their internal environment, a process called homeostasis.

Cell

The most basic unit of life is the cell. The cell is composed of molecules of protein ,carbohydrates, lipids, and nucleic acid.

Response to stimuli

Living things respond to stimuli from their environment.

Control

Referred to the coordination of their bodily activities as well as the rregulation of their processes internal and external. Control referres to the fact that the metabolic Activitiese living things occure in sequence in at a specific rate.

Adaptation

Refers to the physical adjustments organisms make over relatively long periods of time to change and then environment

Cells

The basic unit if life

Internal organization

The cell itself is characterized by internal organization and in the case of multicellular organisms the organism possesses an overall internal organization

2 basic cell types prokaryotic and eukaryotic cells

The distinction is that eukaryotic cells have a "true" nucleus containing their DNA, whereas prokaryotic cells do not have a nucleus. Both eukaryotes and prokaryotes contain large RNA/protein structures called ribosomes, which produce protein.

metabolism

The sum of all chemical reactions that occur in an organism.
