Cells are tiny units that make up an organism. Cells can grow, respond to their surroundings,and reproduce. Cells are very complex and organized.
This picture shows how small and complex cells are. It also shows all the different types of cells that make up our body.
All organisms need energy to grow taller, complete tasks, and to play sports. Organisms use energy and a constant supply of materials to grow, develop, and reproduce. All living things need energy and materials to stay alive. A metabolism is the combination of chemical reactions living things use to carry out life processes.
This picture is showing how a plant gets energy from the sun. The plant then uses this energy to fulfill it's daily tasks and stay alive.
All organisms cal produce offspring through some process of reproduction. Their are two kinds of reproduction, sexual and asexual. Most organisms reproduce sexually. In sexual reproduction two parent cells come together to create a cell of a new organism. In asexual reproduction the organism divides and produces an offspring identical to it. This new cell will only have one parent.
This picture shows how cells reproduce both sexually and asexually. I think this picture is helpful because it provides a clear distinction between the two types of reproduction.
Organisms can detect and respond to stimuli in their environment. A stimulus is a signal that causes an organism to respond. External stimuli come from the environment outside of the organism. For example, light and temperature. Internal stimuli comes from within the organism.
This picture is showing a flower responding to an external stimuli, the light.
Every living thing changes throughout their life. However, the basic traits that an organism inherits from its parents do not change. This change is called evolution. Some changes over a few decades might be hard to recognize and may seen insignificant, but changes that happen over a hundreds,thousands, and millions years can be very big and noticeable. This ability to adapt over time and change is very important in today's world.
This picture is showing how humans evolved, or changed overtime. As a species we evolved from gorillas and other ape like creatures.
Even with the world around us always changing organisms are able to keep internal conditions like temperature and water content pretty constant. This relatively constant set of conditions is called homeostasis. Homeostasis is partially maintained by internal stimuli. An example of this is, when you need more water to keep a healthy homeostasis your internal stimuli makes you feel thirsty.
This picture is showing a person drinking water. This relates to the characteristic, all living thinks can maintain an internal balance because in order to maintain an internal balance you need to drink water and stay hydrated. This concept relates back to homeostasis.
When cells reproduce asexually the offspring and the parent have the same traits.When organisms reproduce sexually they have different traits then their offspring. The molecule that directs inheritance is called DNA. DNA is the genetic code that determines the inherited traits of every organism on Earth.
This picture is showing what DNA looks like up close. DNA is the universal genetic code the determines all organism's traits.
All organisms grow during some point in their lives. For some single celled organisms growth in just an increase in size. However, multi-cellular organisms go through a process called development. Differentiation is when a cell divides multiple times during its developmental stages. This results in new cells with different shapes and structures.This process is called differentiation because it creates cells look different from one another and preform different functions.
This picture is showing what a butterfly looks like while it is going through the developmental stages.
