Characteristics of living things
An organism made up of many cells (Ex. animals, plants)
multicellular
A cell structure that controls which substances can enter or leave the cell.
cell membrane
Cells that DO NOT contain a nucleus or membrane-bound organelles
prokaryotic cells
some unicellular organisms, such as bacteria, have tail-like structures used to move around
flagella
Director of the cell, contains DNA
nucleus
A reproductive process that involves only one parent
asexual
A gel-like fluid inside the cell in which the organelles are suspended
cytoplasm
Robert Hooke discovered cells in the year ______.
1665
The levels of biological organization is order of MOST complex to LEAST complex
organism, organ system, organ, tissue, cell
An organelle found in plant cells where photosynthesis takes place
chloroplast
living things react to changes in their environment known as this
stimuli
Make proteins
ribosomes
plant and animal cells are part of a larger category of cells known as this
Eukaryotic cells
A simple sugar that is an important source of energy.
glucose
cell organelle that breaks down waste
lysosome
A relatively stable or balanced internal environment needed in order to survive
homeostasis
Make energy molecules called ATP from food molecules (sugar) and oxygen
mitochondria
ALL cells (prokaryotic and Eukaryotic) have these four things in common
ribosomes, cell membrane, cytoplasm, DNA
Fat molecules
lipid
connected to the nucleus, has ribosomes on it and helps them make proteins, transports materials throughout the cell
Rough Endoplasmic Reticulum
These types of organisms get their energy from the sun. Also known as producers.
Autotrophs
package cellular material into Vesicles and ship them to the cell membrane so they can leave the cell
golgi body
The three organelles found only in plant cells
cell wall, chloroplast, central vacuole
This type of organelle is found in both plant and prokaryotic cells, but not animal cells
cell wall
a clump of DNA found in the cytoplasm of a prokaryotic cell
nucleoid
