RHS cell organelle
organelle and their functions
| Question | Answer |
|---|---|
| rigid outer covering of plant cells, made of cellulose, provides support and protection | Cellulose |
| a plant plastid containing chlorophyll and is the site of photosythensis | chloroplast |
| refers the to property of the cell membrane which allows the cell membrane to allow certain substances to cross the membrane and other substances cannot cross. | Selectively permeable |
| Membrane proteins attached to the surface of the cell membrane | peripheral proteins |
| membrane proteins that embedded the lipid bilayer of the cell membrane | integral proteins |
| the name for the descriptive model of the cell membrane | fluid mosaic model |
| The region between the cell membrane and the nuclear membrane | cytoplasm |
| the gelatin-like aqeuous fluid by which the organelles are surrounded | cystosol |
| transfers energy from organic compounds like carbohydrates to ATP, the powerhouse | mitochondrion |
| site of protein synthesis | ribosomes |
| prepares proteins for export, synthesizes lipids and breaks down toxic substances | endoplasmic reticulum |
| processes and packages substances for export | golgi appartus |
| digest molecules, worn out organelles and unfamiliar substances. suicide sacs | lysosomes |
| cytoskeleton, can be used for locomotion, contributes to movement and divsion of cells made up of microfilaments | microtubules |
| part of the exoskeleton makes up microtubules | microfilaments |
| long whiplike structures made up of microtubles and used for locomotion | flagella |
| small hair-like projections of the cell surface, made up of microtubules and are used to move substance across the surface of the cell | cilia |
| stores DNA. synthesizeds RNA and ribsomes, control center. | nucleus |
| vacuole | storage site |
| plastid | stores food or pigments. |
| protein making up microfilaments | actin |
| bundles of microtubules which function in cell division and arise from the centrioles | spindle fibers |
| produces the spindle fibers during cell division | centrioles |
| double membrane surrounding the nucleus | nuclear membrane |
| small holes in the nuclear envelope | nuclear pores |
| spherical structure in the nucleus where ribosomes are produced | nucleolus |
| plastid containing chlorophyll | chloroplast |
| the flattened sacs withing the chloroplast | thylakoids |
| fine strands of DNA and protein found in the nucleus | chromatin |
| chromatin strands coiled up and densley packed ready for cell division | chromosomes |
| The folded inner membrane of the mitochondria | cristae |
