The diffusion of water molecules across a membrane is....
osmosis
condition in which an orgnaism's internal environment is kept stable and in balance
homeostasis
An organism which can produce its own food.
autotroph
Name the stages in order of Mitosis.
Interphase (resting stage) Prophase, Metaphase, Anaphase, Telophase Cytokinesis (splitting)
What are the raw materials for cell respiration?
glucose and oxygen
define diffusion
particles moving from an area of higher concentration to lower concentration.
Water moving across a membrane is which type of transport?
an example of passive transport
a chemical which speeds up a reaction in a body
an enzyme
what is happening during Metaphase?
Chromosome pairs align in the center
What is the equation for cell respiration?
C6H1206 + 6O2 ----> 6CO2 + 6H20 + ATP
Which organelle does cellular respiration take place in?
mitochondria
What is the name for the membrane that allows some particles in and keeps others out?
selectively permeable
(semi-permeable)
energy releasing process not requiring oxygen
fermentation
What are stages of cell cycle?
interphase, mitosis, and cytokinesis
How are cell respiration and photosynthesis opposite?
What one process creates the other needs. Photosynthesis creates O2 and cell respiration will create CO2, which photosynthesis needs.
Give an example of diffusion.
particles moving from an area of higher concentration to lower concentration.
Why do we need both active and passive transport?
We need transport to happen naturally, moving from areas of high to low (passive transport) We also need to be able to control what stays in the cell and what leaves the cell which requires energy usage (active transport)
mitosis begins in which organelle
nucleus
Name two reasons for mitosis
growth
repair
asexual reproduction
Where does a producer get energy from to perform photosynthesis?
sun
Which organelle does photosysnthesis take place in?
chloroplast
What is endocytosis?
when the cell uses energy to engulf a particle
During which phase of cell cycle does DNA replicate?
interphase
