100
This invention allowed scientists to view organisms under high magnification
What is a Microscope
100
Thin flexible barrier that surrounds a cell and controls what enters the cell and exits the cell (analogy: doors of the school)
What is the cell membrane
100
What is another name for cell division?
What is Mitosis
100
What is the end result of meiosis?
4 half (haploid) cells
100
What do you call a cell that self destructs?
apoptosis
200
This theory states that all living things are made of cells, cells are the basic unit of life, and new cells come from existing cells (cell division)
What is The Cell Theory
200
The rigid supporting layer of a plant cell (analogy: outer bricks of the school)
What is a cell wall
200
What are the 3 functions of cell division?
What is to grow, repair, and reproduce
200
During what phase does crossing over occur?
Prophase 1
200
what type of solution has a high concentration of solute (ex. sugar) in comparison?
hypertonic
300
Tiny cell structures that carry out specific functions inside a cell
What are organelles
300
The "brain" of the cell that helps the cell carry out its functions and contains DNA (analogy: Principal of the school)
What is the nucleus
300
What happens during Interphase of the cell cycle?
Cells will grow, copy their DNA, and prepare to divide
300
What do you call the fusion of sperm and egg?
a zygote
300
draw a duplicated chromosome and label sister chromatid, and centromere
Answers will vary/ see drawing
400
This process helps odor travel fast through the air (example: smelling a skunk from inside your house)
What is diffusion
400
Gel-like fluid that holds the organelles in a cell
What is cytoplasm
400
What would happen if cells did not divide?
Different answers
400
list the 11 main stages of meiosis in order
interphase, prophase 1, metaphase 1, anaphase 1, telophase 1, cytokinesis 1, prophase 2, metaphase 2, anaphase 2, telophase 2, cytokinesis 2
400
This is where plants gain energy from the sun
chloroplast
500
Diffusion of water across a selectively permeable membrane (example: when you soak a raisin in water, the raisin appears lighter in color and plumper in size)
What is Osmosis
500
The powerhouse of the of the cell that creates energy for the cell (analogy: Cafeteria staff of the school)
What is the mitochondria
500
Math Problem! How many cells would there be after four divisions?
What are 16 cells
500
What is the purpose of meiosis?
for reproduction, to create genetic variety.
500
What is the difference between mitosis and meiosis?
Mitosis- Creates 2 identical cells with only 1 cell division.
Meiosis- Creates 4 cell with different DNA combination that have half as many chromosomes through 2 cell divisions.
