Cell Biology Flashcards
Name the structure of a plant cell and what they do
Cell wall - provides protection
Vacuole - maintains the cells water balance
Nucleus - controls the cell activity’s
Ribosomes - produces protein
Chloroplast - absorbs light for photosynthesis
Cytoplasm - responsible for giving the cell its shape
Name the structure of an animal cell and what they do
Cell membrane - controls what goes in and out of the cell
Nucleus - controls the cells activities
Cytoplasm - contains enzymes
Mitochondria - produces energy
Ribosomes - produces protein
What are the two types of microscopes
Electron and light
What is cell division
Cell division is is the division of a cell into two daughter cells with the same genetic material
What is mitosis
Mitosis is a type of cell division which results in two daughter cells having the same number of chromosomes as the parent nucleus. (Reproduce with themselves)
What is meiosis
Meiosis is a type of cell division where a single cell divides twice to produce four cells containing half of the number of chromosomes of the parent cell (reproduces with something else) (sperm cells and egg cells)
What is the difference between eukaryotic and prokaryotic cells
Prokaryotic cells do not have a nucleus but a eukaryotic cell has a nucleus
What DNA bases pair up with each other and what are the bases attached to
A pairs with T, C pairs with G. They are attached to a sugar molecule and a phosphate molecule called nucleotide.
How are nucleotides arranged
Nucleotides are arranged in two long strands of DNA called a double helix
