Basic life
The basic unit of life
What is a cell?
Four components all cells have in common
What are cell membrane, cytoplasm, DNA, ribosomes?
Permeable structure outside of the cell membrane that is found in plants, fungi and bacteria; provides rigidity and support
What is the cell wall?
Vascular cells that carry oxygen and nutrients; a part of the immune system, and defend the body against disease
What are red blood cells?
What are white blood cells?
The mechanisms of active transport
The mechanisms of passive transport
What are uses ATP, high concentration, endocytosis, exocytosis?
What are high to low concentration, diffusion, osmosis, facilitated diffusion?
An organism made of one cell; an organism made of two or more cells
What is unicellular; what is multicellular
Site a photosynthesis, contains chlorophyll
What are chloroplasts?
Site of temporary storage; it is a larger organelle in plants
What are vacuoles?
Expand and contract to allow movement
What are muscle cells?
The characteristics of sexual reproduction
What is involves two parents, egg is fertilized by sperm to form a zygote, offspring are genetically different, results in genetic variation, involves meiosis?
The characteristics of life that all organisms possess
What is use energy, adapt, their environment, grow and develops, able to reproduce, made of cells, maintain homeostasis, respond to stimuli, has genetic material?
Contains DNA, which codes for protein
What is the nucleus?
Site of aerobic cell respiration; contains many folds that increase the amount of space available for ATP production
What are mitochondria?
Serve as male gametes
What are sperm cells?
The diffusion of water; when cells are placed in solutions that have different concentrations water will move from areas with a low concentration of solute to areas with a high concentration of solute
What is osmosis?
The characteristics of prokaryotes
What are first cells to evolve, lack membrane bound organelles, small cells, simple, unicellular, no nucleus, DNA is circular and contained in the cytoplasm, cell division, by binary fission, asexual?
The site of protein synthesis, where mRNA and tRNA meet
What are ribosomes?
Organelles that are unique to plant cells
What are the large central vacuole, cell wall, and chloroplast?
Send electrical signals from the brain to communicate with other parts of the body
What are nerve cells?
The characteristics of asexual reproduction
What is involves one parent, the cell divides into two daughter cells, offspring are genetically identical, results in no genetic variation, and involves mitosis?
The characteristics of eukaryotes
What are evolved from prokaryotes, have membrane bound organelles, larger cells, more complex, often multicellular, have a nucleus, DNA is linear and contained in the nucleus, cell division, by mitosis and meiosis, asexual and sexual?
Semi-permeable phospholipid bilayer that regulates what enters and exits the cell
What is a plasma (cell) membrane?
The process of maintaining homeostasis
What is maintaining their temperature, glucose, water, and pH levels?
Unspecialized or undifferentiated cells that can become any cell type
The process by which a ___ becomes a specific type of cell with a multicellular organism
What are stem cells?
What is differentiation?
A type of cells vision that makes cells that are considered diploid
Produces haploid cells
What is mitosis?
What is meiosis?
