(44 cards)
Cell
The smallest unit that living organisms are made out of.
Cell membrane
Keeps the cytoplasm in place inside the cell.
Cell wall
Supports the call on the outside to maintain it’s shape.
Nucleus
Contains DNA, genes and chromosomes in the middle of the cell.
Nucleolus
Transports rRNA and helps to make proteins and ribosomes.
Nuclear envelope
Only in Eukaryotic cells and it surrounds the nucleus.
DNA
Basic structure of all cells. Contains information on genetics. Creates RNA
RNA
Carries around DNA and creates proteins.
Proteins
Aids in building tissue and works as a fueling source.
Chromosomes
Contains genetic information and made up of nucleic acids and proteins.
Nucleoid
Contains genetic material in a prokaryotic cell.
Cytoplasm/Cytoskeleton
Has microtubules (movement) and microfiliments, outside the nucleus and inside the membrane.
Organelle
Any structure within a cell wall/membrane.
Mitochondria
The powerhouse of the cell. Converts stored energy into usable energy.
Chloroplasts
Change solar energy into chemical bond energy
Leucoplast
Stores food and starches.
Chromoplasts
A plastid with an orange or yellow pigment .
Ribosomes
Involved in protein synthesis. rRNA
Smooth endoplasmic reticulum
Protein and lipid synthesis, no ribosomes
Rough endoplasmic reticulum
Protein and lipid synthesis, contains ribosomes
Lysosomes
Enzymes that break down substances in a cell.
Vacuole
Stores water and food for the cell.
Plastids
Stores food and pigments
Diffusion
The spreading of a higher concentration to a lower concentration.
