Cells are the smallest living unit of organisms.Cells are complex and highly organized.

Organisms may be composed of a single cell (like bacteria) or many cells (like plants, animals, and fungi).

Sexual Reproduction Involves 2 parents Egg fertilized by sperm to make a ZYGOTE Offspring DIFFERENT from parents

Asexual reproduction

Involves a single organism or cell

Cell divides Offspring

IDENTICAL to parent

DNA (deoxyribose nucleic acid) carries the genetic code for all organismsAll organisms contain DNA

DNA codes for the proteins that make up cells & do all the work

Organisms grow by producing more cells & by cell enlargementOrganisms develop as they mature into an adult organism

Autotrophs can make their own food

Heterotrophs can NOT make their own food

These cyanobacteria stromatolites are in shark bay, Australia. They are halophiles!

Page 14: 1. 1. Basic unit is the cell 2. Reproduce 3. Have DNA 4. Grow & develop 5. Obtain & use energy 6. Respond to their environment 7. Maintain homeostasis

Organisms respond to temperature, water, food supplies, etc. in order to survive & reproduce

Keeping the internal environment of the cell or organism within the ranges required for lifeStable internal conditions of pH, temperature, water balance, etc.

Groups of organisms (not individuals) change over time in order to survive within changing environments.Fossil records show changes in groups of organisms
