Cell Energy
What is Photosynthesis?
The process where autotrophs (an organism that has the ability to make its own food) convert light energy into chemical energy, using sunlight.
What is Mitosis?
Its part of the cell cycle in which cells divide their nucleus and DNA.
What are some Human Impacts?
Air pollution, Acid Rain, Deforestation
What is genetics?
Genetics is the study of heredity, or passing characteristics from parent to offspring.
What is Cell Transport?
Particles move in response to a concentration gradient
Solvent = Dissolver (ex: water)
Where does photosynthesis occur?
Photosynthesis takes place in the leaves of plants.
What is Cytokinesis?
Its part of the cell cycle in which cells divide their cytoplasm and organelles.
What is a Renewable resource?
A type of natural resource that can be replenished or takes a rather short period of time for nature to produce to sustain the rate of consumption, example wind or water energy.
What is Meiosis?
A different type of cell division where gametes have half the number of chromosomes as the parents.
What is Diffusion?
A type of passive transport where molecules move from high concentration to low concentration without using energy.
What is Cellular Respiration?
Process by which Cells make ATP (energy) by breaking down organic compounds (food)
What are the four Stages of Mitosis?
Prophase, Metaphase, Anaphase, Telophase
What is Non-renewable Resources?
Natural resources that exist in fixed amounts and can be used up, examples include fossil fuels such as petroleum, coal, and natural gas.
What is Nondisjunction?
The failure of one or more pairs of homologous chromosomes or sister chromatids to separate normally during nuclear division, usually resulting in an abnormal distribution of chromosomes in the daughter nuclei.
What is Facilitated Diffusion?
a type of passive transport and diffusion where molecules move from high concentration to low concentration without using energy but with using a protein channel.
Where Does Cellular Respiration Take Place?
It actually takes place in two parts of the cell:
Starts in the cytoplasm
Moves to the mitochondria if oxygen is present.
What is Asexual Reproduction?
The process where 1 parent cell splits into 2 genetically identical individuals. This produces clones and there is no genetic variation.
What is the cause of Deforestation?
Human are removing trees to make room for new homes, using it for lumber, clear-cutting for agriculture, and expanding businesses/roads.
What is Incomplete Dominance?
Neither allele is dominant or recessive.
When heterozygous, a third blending intermediate phenotype appears.
Use two different letters, but ALL capital!
What is a Concentration Gradient?
It's the difference in the amount of molecules on each side of the cell membrane.
It causes particles to move!
What are the 2 types of cellular respiration?
Aerobic Respiration and Anaerobic Respiration:
What are the Types of Asexual Reproduction?
Budding
Binary fission
Sporulation
Regeneration
Vegetative Propagation
What are the effects of Deforestation?
Loss of habitat for animals (decreases biodiversity) and this upsets the carbon cycle. No photosynthesis to remove excess carbon. Also, increases erosion (loss of soil).
What is Codominance?
Both alleles are expressed and both contribute to the phenotype (both show up).
When heterozygous, both phenotypes are represented separately.
Use two different letters, but ALL capital!
What is Dynamic Equilibrium?
When molecules are balanced and continue to move forward and backward across the membrane with chemical reactions happening simultaneously and constantly.
