•
Cytokinesis- division of cytoplasm
•
Mitosis-four stages of cell division
–
Mitosis phase 4- nuclear membrane forms around chromosomes; mitosis is complete
–
Mitosis phase 3- stage at which the chromatids separate and move to opposite sides of
the cell
–
Mitosis phase 2 – stage at which paired chromosomes align at the cell’s equator
–
Mitosis phase 1- begins; stage at which chromosomes condense from long strands to
rodlike structures
•
Interphase- stage at which chromosomes are copied
•
ATP-the substance that supplies energy to fuel cell activities, such as growth
•
Cellular respiration-p150
C6H12O6+6O2  6CO2 + 6H2O + energy
Photosynthesis  cellular respiration (carbon dioxide and water) when energy is added
•
Photosynthesis- process a plant uses to create glucose/food
•
Fermentation-process cells use to produce energy without oxygen
•
Mitochondria- place where cellular respiration in eukaryotes take place
•
Chromosomes- structures in which DNA can be found
•
Cell cycle- the life stages of a cell
•
Homologous chromosomes-23 pairs of human body cells
•
Binary fission-process of cell division in bacteria
•
Cancer- cells dividing at an uncontrolled rate (usually a tumor)
•
During cytokinesis
•
–
In a plant cell - cells form a cell plate;cells of other eukaryotes have a cell wall, division
of cytoplasm, (by cell plate), separates into 2 new cells
–
In an animal cell- eukaryotes lack a cell wall, & cell pinch in 2 during cytokinesis
–
What is not used to make glucose in photosynthesis?
Fermentation-
•
–
Takes place in muscle cells when they need energy
–
Not receiving oxygen to make ATP by cellular respiration
–
Fermentation when needs energy and no oxygen
Oxygen–
Released during photosynthesis
–
In cellular respiration oxygen is combined with glucose; produces energy; when this
happens plants grow, repair damaged cells, replace dead cells
–
Plants can survive in the world without animals(mammals), but animals(mammals) can
not survive in the world without plants.
–
We need plants plants produce oxygen we need to breathe, plants help provide a
food source.
–
Plants  make their own food, take carbon dioxide and water to make glucose. They
help recycle the carbon dioxide/oxygen; are a food source for others
–
Learning about cell growth, division, and behavior under different circumstance helps
gain to prevent plants from dying, mutating, using DNA to replicate (make more of a
certain plant). Helps understand nutrition and what foods help keep plants healthy and
strong
