Cell Structures
This structure surrounds the cell and controls what goes in and out.
what is the cell membrane?
Movement of substances from high concentration to low concentration without energy.
Diffusion
The process by which body cells divide to make identical cells.
mitosis
The gas plants take in during photosynthesis.
Carbon Dioxide (CO2)
Inputs of cellular respiration
glucose and oxygen
This part of the cell contains DNA and controls cell activities.
Nucleus
The movement of water across a cell membrane.
osmosis
The stage of the cell cycle when the cell grows and copies DNA.
interphase
the main source of energy used to split the water molecules
light energy
Organisms that use cellular respiration
all living organisms
These are known as the “powerhouses” of the cell because they release energy.
mitochondrion/mitochondria
This type of transport requires energy to move substances against the concentration gradient.
active transport
process of chromosomes being pulled apart to opposite poles of the cell
anaphase
absorbs red and blue light very effectively, but it reflects green light, appearing green to the human eye
chlorophyll
cellular respiration that does not use oxygen
fermentation
This structure is found in plant cells and helps them make food.
chloroplast
When a cell membrane surrounds and brings in large particles.
Endocytosis
chromatin
Organisms that make their own food
Autotrophs
Organelle where stage 2 cellular respiration occurs
mitochondria (stage 1 is in the cytoplasm)
Packages and distributes materials from the ER
Golgi Apparatus
The solution where there is more solvent (water) outside of a cell causing the cell to swell.
Hypotonic
4 functions of cell repair
Stage 2 of photosynthesis is known as
Calvin Cycle
In stage 2, ATP energy is produced in a process known as
Kreb's Cycle
