2 Organisation Of The Organism Flashcards
Structure of animal cell:
cell membrane, nucleus, cytoplasm, ribosome, mitochondria, vacuoles
Structure of bacterial cells include:
Cell wall, cell membrane, cytoplasm, ribosome, circular dna, plasmids
Structure of plant cell include
Cytoplasm, cell wall, cell membrane, ribosome, mitochondria, nucleus, chloroplasts, permanent vacuole
How are new cells produced
By the division of existing cells
ciliated cells
movement of mucus in the trachea and bronci
palisade mesophyll cells
site of photosynthesis
root hair cells
absorption of water and mineral ions
neurones
conduction of electrical impulses
red blood cells
transport of oxygen
sperm and egg cells
reproduction
magnification formula
image size / actual size
conversion of millimetres (mm) to micrometres (μm)
1mm = 1000 μm
ribosomes
synthesis of proteins
mitochondria
site of cellular respiration
cytoplasm
a jelly-like material that contains dissolved nurtients and salts and structures (organelles). where many of the chemical reactions happen
cell membrane
partially permeable, controls the movement of substances in and out of the cell
chloroplasts
contain chlorophyll which absorbs light energy for photosynthesis, it contains the enzymes needed for photosynthesis
vacuole (permanent)
- storage area for water and dissolved substances (e.g. Ions, sugars and waste products
- filled with cell sap to help keep the cell turgid
vacuole (temporary)
used to store or transport substances
cell wall
made from cellulose fibres and strengthens the cell and supports the plant
