Vacuole. Cell membrane Bacteria Cell: Bacteria cells do not have a nucleus, they contain chromosomal DNA and Plasmids which also contain genes.

Function: Absorption of water and mineral ions from soil. Adaptations: • They greatly increase surface area available for water to move into the cell Large finger-like projection for absorption. They have a large permanent vacuole that speeds up the movement of water by osmosis from the soil across the root hair cell. Root Hair Cell: fo CYTOPLASM To MITOCHONDRION Mitochondria for active transport of mineral ions. • Remember that chloroplasts are not found in these cells - there's no light for photosynthesis underground!

Function: Transports electrical signals to the brain. • Lots of dendrites to make connections to other nerve cells. ROOT HAIR MYELIN SHEATH NERVE ENDING (MADE FROM SCHWANN CELLS) • A long axon that carries the nerve impulse from one place to another. • The nerve ending (synapse) contain lots of mitochondria to provide the energy needed to make the transmitter chemicals.

Adaptations: • They contain haemoglobin - a red protein that combines with oxygen. They have no nucleus so they can contain more haemoglobin. They are small and flexible so they can fit through narrow blood vessels. They have a biconcave shape (flattened disc space) to maximise their surface area for oxygen absorption. -stage Cell structure and Transport slide CYTOPLASM to CONTAINING objective lens HAEMOGLOBIN https://app.studysmarter.de/studyset/12936274/summary/69691220/edit CELL MEMBRANE Create the best notes with StudySmarter.de Functi on: Red blood cells transp ort oxygen from the lungs to the body and Akta 240 8/9 09/04/2023, 18:38 magnification x 1000 Real size x Magnification of object 1m 1000 mm + 1000 Size of image size of image real size of image Study Smarter Cell structure and Transport TO CONNVERT mm → jum 1 mm x 1000 + 1000 1000μm TO CONNVERT um → mm https://app.studysmarter.de/studyset/12936274/summary/69691220/edit x 1000 1μm: = 1000nm + 1000 Create the best notes with StudySmarter.de Axta 200 9/9
