| Name all the parts in a plant cell. | Nucleus, Vacuole, Mitochondria, Chloroplasts, Cytoplasm, Ribosomes, Cell wall, Cell membrane. |
| Name all the parts in an animal cell. | Nucleus, Mitochondria, Cytoplasm, Ribosomes, Cell Membrane. |
| What is a eukaryotic cell? | * A cell which has a clearly defined nucleus * They contain membrane bound organelles such as the nucleus and the mitochondria. |
| What is a prokaryotic cell? | * cells that do not have a true nucleus or most other cell organelles * Organisms that have prokaryotic cells are unicellular. |
| What is the function of the nucleus? | * The nucleus is the command center of the cell and directs all of its activity * it also contains all the chromosomes with the DNA |
| What is the function of the cell membrane? | * keep toxic substances out of the cell * controls what goes in and out of the cell * separates the inside of cells from the outside *plasma membrane selectively permeable to ions and organic molecules |
| What is the function of the cell wall? | * the cell wall provides structure to the plant cell * it also bonds with other cell walls to form the structure of the plant. |
| What is the function of the chloroplasts? | * absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant * conducts photosynthesis |
| What is the function of the mitochondria? | * powerhouses of the cell * organelles that act like a digestive system - takes in nutrients, breaks them down, and creates energy rich molecules for the cell * biochemical processes of the cell are known as cellular respiration |
| What is the function of the ribosomes? | To synthesize proteins . |
| What is the function of the vacuole? | * keep the cell rigid * contains cell sap which stores materials such as nutrients and water and waste matter |
| What is the function of the cytoplasm? | * jelly-like fluid that fills a cell is called cytoplasm, made up of mostly water and salt. * Most of the important activities of the cell occur |
| What two sub-cellular structures do plants cells have but not animal cells? | Plant cells have chloroplasts and a cell wall which animal cells don't have. |
| What do prokaryotic cells have instead of a nucleus? | a nucleoid (meaning nucleus-like) is an irregularly shaped region within a prokaryote that contains all/most of the genetic material, called genophore Unlike nucleus of a eukaryotic cell, it is not surrounded by a nuclear membrane. |
| What is protein needed for? | * creation of body chemicals such as hormones, enzymes * building block of bones, muscles, cartilage, skin, and blood |
