Mitosis
What are the 3 phases of the Mitotic Cell Cycle?
1. Interphase
2. Mitosis
3. Cytokinesis
How many new cells get formed?
4
What is biology?
It is the study of living organisms
Which organelle stores the RNA/DNA?
The nucleic acids
What microscope is in our classroom?
The bright-field microscope
What happens during G1?
Rapid growth
What is a haploid?
Having half the amount of DNA per cell
What are the 2 groups of cells?
1.Prokaryotic
2. Eukaryotic
What s the smallest unit of lipids?
Glycerol
How do you calculate total magnification?
Ocular lense multiplied by objective lense
In which of the 3 main categories does most of the cell process happen?
The interphase- G1, S, G2
What is diploid?
Having a normal amount of DNA per cell - 2 sets of chromosomes
What transports material through the cell to the golgi body and what are the different types?
The ER and there is Smooth ER and Rough ER
What are the 3 functions of carbohydrates?
1. Supply energy for cell processes
2. Form plant structure
3. Act as a short -term energy storage
What is the cell theory?
1. All organisms are made up of one or more cells
2. The cell is the most basic unit of organization in organisms
3. All cells come from cell
What is happening to the cell during cytokinesis?
The cytoplasm and the cell membrane pinches off to divide into new cells
In which phase of Meiosis does the cytoplasm pinch inward until 2 new cells are formed, so now each cell has 23 chromosomes?
Telophase 1
Why is it that the plant cells have a much larger vacuole that a human cell?
Because plants need to store a lot of energy- they do not get energy from food throughout the day like humans do, so they use photosynthesis and then store the energy received from that
How do the ribosomes work if they are so far from the nucleus?
The ribosomes follow the RNA so they are able to do what they need to do without being in close proximity of the DNA
Name the 6 types of microscopes:
1. SEM
2.TEM
3.Dark-field
4.Bright-field
5.Phase contrast
6.Fluorescence
What is karyotype after duplication of chromosomes:
2 pairs, total of 46 chromosomes
In which phase do the chromosomes line up at the center and the spindle fibers attach to centrisomes?
Metaphase 2
Name 3 characteristics of the prokaryotic cell:
Any 3 of these 4:
1. It is less complex and less organized
2. It is smaller
3. Lacks nucleus
4. Includes few cell structures
Name 2 INORGANIC compounds and their uses in the body:
Any 2 of these 4:
1. Water- Makes up most of the blood, and most reactions occur in H20
2. Calcium Phosphate- Gives strength to the bones
3. Hydrochloric Acids- Breaks down foods in the stomach
4. Salts containing sodium, chlorine, and potassium- important for sending messages along nerves
Who is the father of Microscopy and what did he discover?
Antonie van Leeuwenhoek and he was the first person to see and describe tiny living things called microorganisms (- he called them animalcules) and he made his own microscope
