cell
cell structure/cell division
| Question | Answer |
|---|---|
| What is the function of the cell/plasma membrane? | To control what enters and leaves the cell. "selectively permeable" |
| What is the cell/plasma membrane made up of? | A phospholipid bi-layer with protein molecules interspersed within it. |
| What are the active processes of cell transport? | Phagocytosis and Pinocytosis |
| What are the passive processes of cell transport? | Osmosis and Diffusion |
| What Cell transport process requires energy? (ATP - Adenosine Triphosphate) | Phagocytosis and Pinocytosis |
| What cel transport process DOESN'T require energy? | Osmosis and Diffusion |
| What does endocytosis mean? | Transport INTO a cell |
| What does exocytosis? | Transport OUT of a cell |
| What is cytoplasm? | Liquid within a cell |
| What does a nucleus do? | Controls the cells activities (acts as a brain) contains DNA. |
| What is the job of a centriole? | A pair of structures that act as organizes of the nuclear spindle during cell division |
| What does a Mitochondria do? | Cell respiration. Production of energy in the form of ATP (adenosine triphosphate) |
| What are the 2 forms of endoplasmic reticulum? | Rough and smooth |
| What is the function of the RER? | synthesises protein and transports it within the cell |
| What is the function of the SER? | synthesises and transports lipids and steroids |
| Golgi Apparatus/body/complex | modifies a number of cell products. Plays a part in the formation of lysosomes. |
| Lysosomes | Membrane bound sacs containing digestive enzymes. breaks down bacteria, viruses, toxins, non-useful tissues |
| Meiosis occurs in what cells? | germ cells of the ovaries and testicles |
| Where does Mitosis occur? | in the somatic cells of the body |
| What does mitosis involve? | the replicatin of DNA |
| What are the stages of cell division? | Prophase, metaphase, anaphase, telophase |
| how many daughter cells does meiosis produce after one process and what is it called? | 2 stages, 4 daughter cells, haploid |
| how many stages is one process of mitosis, how many daughter cells does it produce and what is it called? | 1 stage, 2 daughter cells, new cells have half he number of parent cells diploid |
| what is the name of the cell membranes outer layer? | hydrophilic |
| what is the name of the inside layer of the cell membrane? | hydrophobic |
