- cell envelope
- a a flattened membrane sac inside the chloroplast, used to convert light energy into chemical energy; where the light reactions of photosynthesis occurs
- b A sticky layer that surrounds the cell walls of some bacteria, protecting the cell surface and sometimes helping to glue the cell to surfaces.
- c string of ribosomes simultaneously translating regions of the same mRNA strand during protein synthesis
- d in a prokaryotic cell, the portion composed of the plasma membrane, the cell wall and the gycocalyx
- e aerobic rod-shaped spore-producing bacterium
5 Multiple choice questions
- rope-like assemblies of fibrous polypeptides in the cytoskeleton that provide support and strength to cells; A component of the cytoskeleton that includes all filaments intermediate in size between microtubules and microfilaments.
- A structure in an animal cell composed of cylinders of microtubule triplets arranged in a 9 + 0 pattern. An animal cell usually has a pair of centrioles involved in cell division.
- strong wall outside a plant cell's plasma membrane that protects the cell and maintains its shape
- a microscopic network of actin filaments and microtubules in the cytoplasm of many living cells that gives the cell shape and coherence
- A eukaryotic cell organelle consisting of a 9 + 0 arrangement of microtubule triplets; may organize the microtubule assembly of a cilium or flagellum; structurally identical to a centriole.
5 True/False questions
peroxisome → enzyme-filled vesicle in which fatty acids and amino acids are metabolized to hydrogen peroxide that is broken down to harmless products
nucleus → Region in prokaryotic cell where DNA is concentrated, not enclosed by membrane
Golgi apparatus → organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy (photosynthesis)
apoptosis → unstructured semifluid substance that fills the space between cells in connective tissues or inside organelles, the surface area exposed to fluids, such as where the production of energy takes place, in a mitochondrion
cell theory → in a prokaryotic cell, the portion composed of the plasma membrane, the cell wall and the gycocalyx
