|
What are the characteristics of life?
|
Composed of cells, different levels of organisation, use energy , grow, reproduce, respond to their environment and adaptation.
|
|
|
What is cilia and flagella?
|
Cilia and flagella either make it possible for the sperm cells to swim or to move liquid
|
|
|
Endocytosis versus exocytosis
|
Endocytosis with the movement of material into the cell and exocytosis is the movement out of the cell
|
|
|
Prokaryotic versus eukaryotic cells ?
|
Bacteria are prokaryotic
|
|
|
What is interface?
|
Takes place before mitosis and replicates DNA
|
|
|
What is prophase?
|
The longest stage of mitosis, the nuclear material disappears, the chromatin condenses into chromosomes
|
|
|
What is metaphase?
|
The shortest stage of mitosis, the chromatin line up at the cell's equator attached the microtubules at the centromere
|
|
|
What is the product of mitosis?
|
Two identical daughter cells
|
|
|
What is anaphase?
|
The centrosomes move towards opposite poles, chromosomes split and move towards opposite poles
|
|
|
What is telophase?
|
Nuclear material reappears and chromosomes condense into chromatid and the centrosomes disappear
|
|
|
What is cytokinesis?
|
Cleavage furrow pinches cytoplasm of animal cells and the plate forms to plant cells thus creating two identical daughter cells
|
|
|
What do mitochondria and chloroplasts do?
|
Mitochondria turns food and oxygen into adoneise teiphosphate which produces energy
|
|
|
What does the phospholipid bilayer consist of?
|
Lipids carbs and cholesterol
|
|
|
Covalent vs ionic bonds
|
Ionic bonds attract and covalent bonds don't because they are non metal
|
|
|
Is an enzyme?
|
Produced by living organisms and act like a catalyst to bring out biochemical reactions
|
|
|
Active versus passive transport
|
Passive transport does not need energy to transport biochemical things because it is moving from a high concentration to a low concentration and active would require energy because it is moving from the same concentration
