LIVING ENVIORMENT: cells Flashcards
prokaryote
cells that lack a nucleus
eukaryote
cells that have a nucleus
mitochondria and chloroplast
have their own DNA and can replicate independently from the cell
viruses
are living but don’t have some fetrues of life are not made up of cells (contain genetic material)
cell membrane
controls what goes on in and out of the cell
cell wall
its ONLY in plant cells, supports and protects cells composed of cellulose nonliving supportive structure
cytoplasm
fluid like contains organelles some chemical reactions occur
nucleus
controls all activities inside of the cell
ribosomes
where proteins are made (found in cytoplasm attached to the ER)
Endoplasmic Reticulum
move materials from one part of the cell to another
Rough ER
have ribosomes
Smooth ER
have NO ribosomes
Mitochondria
power house of the cell the site of respiration producing energy for the cell
centroles
helps cell divison occur ONLY IN ANIMAL
Vacuole
storage (usually stores water)
Lysosomes
breaks down particles and worn out cell parts
nucleolos
makes ribosomes
Golgi body
sorts and packages materials
