equation for photosynthesis
light energy + 6CO + 6H O C H O + 6O
carbon dioxide + water glucose + oxygen
chlorophyll
main pigment found in chloroplasts
heterotroph
an organism that cannot make its own food, is called a consumer
glucose
is sugar produced by photosynthesis
glucose and oxygen
they are products made by photosynthesie
carbon dioxide and water
they are raw materials of photosynthesis
the production of hydrogen and energy
they are the main characteristic of the first stage of photosynthesis
capturing the sun's energy and using energy to make food
they are the first 2 stages of photosynthesis
glucose and oxygen
they are raw materials in cellular respiration
carbon dioxide, water, and energy
they are products of cellular respiration
cytoplasm
is where the cell does the first stage of cellular respiration
mitochondria
is where the cell does the second stage of cellular respiration
alcoholic fermentation
is a type of fermentation that occurs in yeast
lactic acid fermentation
is a type of fermentation that sometimes occurs in human muscle cells
Why are cellular respiration and photosynthesis opposite processes
cellular respiration produces energy and photosynthesis collects energy
what ways are cellular respiration and fermentation alike
they both release energy
what ways are cellular respiration and fermentation different
cellular respiration needs oxygen and fermentation does not need oxygen
Photosynthesis is the opposite of cellular respiration
Fermentation in yeast produces lactic acid
In the first stage of respiration, very little energy is released
oxygen is a consumer of cellular respiration
glucose is a product of photosynthesis
hi
photosynthesis
the process by which a cell cptures energy in sunlight and uses it to make food
autotroph
an organism that makes its own food is called a producer
carbon dioxide
CO
water
H O
glucose
C H O
oxygen
O
cellular respiration
the process by which cells obtain energy from glucose, during this process cells break down glucose and other molecules form food in the presence of oxygen, releasing energy
fermentation
is an energy releasing process that does not require oxygen, during this process cells release energy from food without using oxygen
cell cycle
is the regular sequence of growth and diviswion that cells undergo , during this cycle, a cell grows, prepares for division, and divides into two new cells, which are called "daughter cells"
interphase
the first phase of the cell cycle, the period before cell division, during this phase the cell grows, makes a copy of its DNA, and prepares to divide into two cells
replication
the process by which a cell makes a copy of the DNA in its nucleus before cell division
DNA
holds all the information that a cell needs to carry out its funcitons
chromosomes
a threadlike structure within a cell's nucleus that contains DNA that is passed from one generation to the next, (DNA and Protein form these threadlike structures
mitosis
the second stage of the cell cycle, during this cyle the cell's nucleus divides into two new nuclei and one set of DNA is distributed into each daughter cell
prophase, metaphase, anaphase, and telophase
are the 4 phases of mitosis
what happens during prophase
the chromosomes condense into shapes that can be seen under a microscope
what happens during metaphase
each chromosome attaches to a spindle fiber at its centromere
cytokinesis
is the final stage of the cell cycle, this completes the process of cell division, during this cycle the cytoplasm divides
