What are the reactants needed for photosynthesis to occur?
light energy, water, carbon dioxide
The diffusion of water molecules across a membrane is....
osmosis
What is needed in order for active transport to occur?
ATP
Describe what happens to a cell placed in an hypertonic solution.
The cell membrane would shrink.
Name the stages in order of Mitosis.
Interphase (resting stage) Prophase, Metaphase, Anaphase, Telophase Cytokinesis (splitting)
What are the reactants for cell respiration?
glucose and oxygen
define diffusion
particles moving from an area of higher concentration to lower concentration.
Facilitated requires
a transport protein
Describe the movement of water if a cell was placed into a hypotonic solution.
Water would move into the cell
what is happening during Metaphase 1 in Meiosis?
Chromosome pairs align in the center
Where does photosynthesis take place?
Chloroplast
What are your types of diffusion?
Passive,
Facilitated
Osmosis
Active transport moves
against the gradient, low to high
Describe both the cell shape and water movement if a cell was placed in an isotonic solution
Cell shape would stay the same. The water would flow in and out evenly.
What is happening during anaphase in Mitosis
Chromatids are being pulled to opposite sides of the cell.
Where does cellular respiration take place?
Mitochondria
Diffusion requires...
what is no energy
Endocytosis and Exocytosis is an example of...
what is active transport?
Explain why a cell shrinks when placed in a hypertonic solution.
The water on the inside of the cell has a higher concentration of free moving water molecules, while the water on the outside has a low concentration of free moving water molecules. The water on the inside of the cell will move from an area of high concentration to low concentration, so the water will leave the cell causing the cell to shrink.
Name two differences between Mitosis and Meiosis
Mitosis= 2 daughter cells, identical to parent cell, divides once during the process Meiosis= 4 daughter cells, not identical to parent cell, divides twice during the process
Which gas moves from cellular respiration to photosynthesis?
carbon dioxide
This molecule needs ATP to pass through the membrane
What is sodium?
What happens when a cell is placed in an isotonic solution?
it will stay the same
If a cell starts with 20 chromosomes and goes through mitosis how many chromosomes will the daughter cell have?
20
