BIO 111L: Cells Flashcards
Plasma Membrane
Plant, animal, or both?
Made of protein and phospholipids. Regulates exchange of substances between cell and its surroundings.
BOTH
Cell wall
Plant, animal or both?
Made of cellulose. Provides support and protection.
PLANT CELLS ONLY
Nucleus
Plant, animal, or both?
Controls cell activity and reproduction.
BOTH
Cytoplasm
Plant, animal, or both?
Gel substance in plasma membrane and outside of nucleus. Where chemical reactions occur and organelles are suspended.
BOTH
Mitochondria
Plant, animal, or both?
Releases energy from sugars in form of ATP by cell respiration/metabolism
BOTH
Chloroplasts
Plant, animal, or both?
Transforms light into energy. Contains green photosynthetic pigment, chlorophyll
PLANT CELLS
Ribosomes
Plant, animal, or both?
Protein synthesis.
BOTH
Endoplasmic reticulum
Plant, animal, or both?
Transport of proteins and synthesis of lipids
BOTH
Golgi bodies
Plant, animal, or both?
Modification and packaging of proteins, lipids, and carbs
BOTH
Central vacuole
Plant, animal, or both?
Storage of water, wastes, and nutrients. Depends on volume; influences cell size and shape
PLANT
Lysosomes
Plant, animal, or both?
Contains enzymes for intercellular digestion of bacteria, cell debris, and worn out cell parts.
ANIMAL
Centrioles
Plant, animal, or both?
Organize parts of cytoskeleton in animal cells
ANIMAL
Flagella/ Cilia
Plant, animal, or both?
Aid in locomotion
BOTH
Independent variable
The factor that is manipulated during the experiment because the investigator believes it will have a measurable effect.
Dependent variable
The factors measured by the investigator. It can change if the independent variable changes.
