Cell Structure Flashcards
Name organelles of plant and animal cells (eukaryotic cells) and be able to explain roles
Cell membrane - controls the movement of substances in and out of the cell
Mitochondria - generate and release energy
Cytoplasm - site of chemical reactions
Nucleus - controls activity of cell, where DNA is stored
Ribosomes - where proteins are made
Cell wall - gives cell structure
Chloroplast - site of photosynthesis
Vacuole - used for storage filled with cell sap
Recall the relative size of bacterial cells (prokaryotic cells)
0.2 to 2 micrometers
Describe the difference in how the genetic material is found within eukaryotic and prokaryotic cells.
Eukaryotic has a nucleus
Prokaryotic has a loop of DNA
Explain how the structure of different types of cell relate to their function; Including sperm cells, nerve cells and muscle cells in animals and root hair cells, xylem and phloem cells in plants.
They are adapted to carry out their functions
To be able to calculate magnification, image size and actual size
Image size
___________________________
Actual size x magnification
To be able to convert between cm, mm, micrometers, and nanometers
Cm -> mm = x10
Mm -> um = x1000
Um -> nm = x1000
