Chp. 4 bio
general features of cells
| Question | Answer |
|---|---|
| Unicellular | bacteria made of just one cell. |
| Multicellular | more complex org. like animals. they are made up of many kinds of specialized cells. |
| Cells are bounded by | plasma membrane |
| the plasma membrane encloses the | cytoplasm |
| all cells contain | genetic material(DNA or RNA) |
| all cells have | ribosomes (protein factories) |
| organisms can be broadly classified as | prokaryotes and eukaryotes |
| prokaryotes are comprised of | bacteria, archaea and viruses |
| eukaryotes are comprised | of protists, fungi, animals, and plants. |
| Prokaryotic cells are the | smallest living things. They do not have a nucleus. |
| prokaryotic cell structure | 1) DNA(arranged as nucleoid) 2) ribosomes 3) plasma membranes 4) cell wall 5) pili 6) flagella 7) capsule(in certain bacteria) |
| small cells | have a larger surface area to volume ratio. this permits rapid exchange of materials. very large cells cannot survive. |
| all eukaryotic cells have certain features in common | 1)Nucleus containing DNA 2)Ribosomes 3)Plasma membrane 4)Mitochondria 5)Golgi apparatus 6)Endoplasmic reticulum 7)Peroxisome 8)Cytoskeleton |
| eukaryotic cells features cont. | Additional features unique to animal cells: 1)Flagellum 2)Lysosome 3)Centriole Additional features unique to plant cells: 1)Cell wall 2)Chloroplasts 3)Central vacuole |
| All eukaryotic cell have a | nucleus, cytoplasm, and organelles - smaller structures within the cell. Example mitochondria, chloroplasts |
| Nucleus contains | most of the DNA in eukaryotic cell.(mitochondria and chloroplasts have some DNA) |
| the nuceus is surrounded by | two membranes, the nuclear envelope. Small materials leave and enter the nucleus through nuclear pores. |
| Nucleolus | is a small region within the nucleus where ribosomes are made (ribosomes are used in making proteins). |
| Larger DNA molecules(long fibers) and the proteins attached | are called chromatin. Each fiber is a chromosome. |
| Ribosomes | are particles made up of ribosomal RNA (rRNA) and proteins. where most cell proteins made. |
| Mitochondria | are where energy (ATP) is produced by cellular respiration. |
| golgi apparatus | is a stack of membrane sacs where proteins are further modified and then shipped to their final destination |
| lysosomes | contains digestive enzymes that break down molecules, bacteria, etc. |
| vacuoles | like lysosomes are membranous sacs and are present mostly in plants. |
