LS MISA 2 Flashcards
What organelles do both plants and animals have?
Nucleus, Cytoplasm, Cell Membrane
Give three differences between bacterial (prokaryotic) DNA and eukaryotic DNA
Bacteria don’t have a nucleus. Bacterial DNA is single-stranded. Bacterial DNA may be in the form of small loops called plasmids
Name 5 organelles found in an animal cell
Nucleus, Cell Membrane, Cytoplasm, Ribosome, Mitochondria
What happens in stage one of the cell cycle?
The cell grows and the number of organelles increases
DNA replicates
Name 2 organelles only found in plant cells
Chloroplasts and a permanent vacuole
How is a nerve cell adapted?
Dendrites - to communicate with other cells.
Long axon - To carry impulse over long distances.
Myelin Sheath - to insulate the nerve making impulse movement faster
What is the difference between animal cell differentiation and plant cell differentiation?
Animal cells differentiate for a limited amount of time, whereas most plant cells can differentiate throughout the plants life
How is DNA stored in a cell?
As chromosomes in the nucleus
What happens in stage 2 of the cell cycle?
mitosis - one set of chromosomes is pulled to each end of the dividing cell and the nucleus divides
What happens in stage 3 of the cell cycle?
the cell splits in 2
What is mitosis used for?
Growth, Repair, Replacement and Asexual reproduction
What is a stem cell?
An undifferentiated cell
