cells Flashcards
cells
building blocks of organisms
eukaryotic cells
- complex
- animals and plants
prokaryotic cells
- smaller and simpler
- bacteria
animal subcellular structures
- nucleus
- cytoplasm
- cell membrane
- mitochondria
- ribosomes
plant subcellular structures
- nucleus
- cytoplasm
- cell membrane
- mitochondria
- ribosomes
- cell wall
- permanent vacuole
- chloroplast
nucleus
contains genetic material that controls the activities of the cell
cytoplasm
most chemical reactions take place. contains enzymes that control the reactions
cell membrane
holds the cell together and controls what goes in and out
mitochondria
where most aerobic respiration reactions take place. releases energy the cells need to work
ribosomes
where proteins are made
cell wall
made of cellulose. supports and strengthens the cell.
permanent vacuole
contains cell sap, fixes rigidity in the cell
chloroplast
where photosynthesis occurs, which makes food for the plant. contains a green pigment called chlorophyll which absorbs light
bacteria cells
- cell membrane
- cell wall
- cytoplasm
- singular strand of DNA that floats freely in
cytoplasm - one or more rings of DNA called plasmids
