Biology

Biotic

Living things in an ecosystem, including the organic matter they produce

Abiotic

Without life; nonliving parts of and ecosystem that supports biotic things

Autotroph

An organism that can make its food/energy, usually through photosynthesis

Heterotroph

An organism that relies on other organisms for food/energy

Sexual

offspring from 2 parents that is genetically different than the parents

Asexual

offspring from 1 parent that is identical to the parent

Unicellular

an organism made of one cell that can perform all functions of life

Multicellular

An organism made of many cells that are specialized to perform all functions of life

Prokaryotic

Simple, smaller cell, DNA freely floating in the cytoplasm

Eukaryotic

Complex, larger cell, DNA contained in the nucleus

Cell

Basic unit of all living things, carries out activities that keep living things alive

Nucleus

Brain of the cell, holds the DNA of the cell

DNA

tiny strands that have genetic information

Cell Membrane

controls what goes in and out of the cell

Cell Wall

gives the cell a shape (plants and fungi)

Cytoplasm

gel like substance that holds all the organells

Chloroplast

found in plant cells, used for photosynthesis

Characteristics of Life

life cycle, energy intake, reproduce, made of cells, responds to the environment, eliminate waste

Domain Archaea

No nucleus, specialized cell wall, nourishment in both ways, unicellular, asexual reproduction, lives in harsh conditions

Domain Bacteria

No nucleus, cell wall, nourishment in both ways, unicellular, asexual reproduction, found everywhere

Domain Eukarya

Domain of all organisms whose cells have nuclei, including protists, plants, fungi, and animals

Kingdom Protista

Cell membrane, nourishment in both ways, can either be unicellular or multicellular, can ether reproduce asexually or sexually, found mostly in water

Kingdom Fungi

Cell wall, heterotroph, can either be multicellular or unicellular, can reproduce sexually or asexually, found everywhere

Kingdom Plantae

Cell wall, autotroph, multicellular, can reproduce sexually or asexually, found everywhere

Kingdom Animalia

Cell membrane, heterotroph, multicellular, most sexual reproduction, found everywhere

Organism

anything that can independently carry out life processes

Species

Group of organisms that are similar

Population

Group of individuals of the same species that live together on the same area

Community

All the populations of different species in the same area

Ecosystem

A Community and their abiotic factors

Ecology

the study of living things and their environment

Taxonomy

classification of organisms by characteristics
