Genetic Structures
This is a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.
What is a chromosome?
This is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
What is Mitosis?
This is the first and the first development stage of a cell life cycle.
What is the G1 Phase?
This is the first stage of cell division, during which the chromosomes become visible as paired chromatids and the nuclear envelope disappears.
What is Prophase?
These are organisms who make (or produce) their own food.
What are Producers?
This is each of the two threadlike strands into which a chromosome divides longitudinally during cell division. Each contains a double helix of DNA.
What is a Chromatid?
This is a special type of cell division that reduces the chromosome number by half, creating four haploid cells, each genetically distinct from the parent cell that gave rise to them.
What is Meiosis?
This is the second phase and the first phase of replication in cellular reproduction.
What is the S phase?
This is the second stage of cell division during which the chromosomes become attached to the spindle fibers.
What is Metaphase?
These are usually herbivores and arthropods that feed on autotrophic plants, which produce their own food through photosynthesis.
What are Primary Consumers?
This is a minute particle consisting of RNA and associated proteins found in large numbers in the cytoplasm of living cells.
What are ribosomes?
This is the action of a cell creating a copy of itself.
What is Replication?
This is the third phase and the second development phase of cellular reproduction.
What is the G2 phase?
This the stage of cell division in which the chromosomes move away from one another to opposite poles of the spindle.
What is Anaphase?
These are organisms that eat smaller consumers for energy.
What are Secondary Consumers?
This is ribonucleic acid, a carrier of instructions from DNA to create more cells>
What is RNA?
This type of reproduction creates genetically-identical organisms because an individual reproduces without another.
What is Asexual reproduction?
This is the fourth phase, the phase with mitosis, and the reproductive phase of cellular reproduction.
What is the mitotic phase?
This the final phase of cell division, in which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.
What is Telophase?
This is a carnivore at the topmost level in a food chain that feeds on herbivores and other carnivores
What are Top Level Consumers?
This is deoxyribonucleic acid, the basic building block of life.
What is DNA?
This type of reproduction works with the genetic material of two individuals from the same species combines to produce genetically-different offspring; this ensures mixing of the gene pool of the species.
What is Sexual reproduction?
This is the other half of the mitotic phase.
What is cytokinesis?
This is sometimes considered the second phase of mitosis (which is put in between the first two phases), the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.
What is Prometaphase?
This is a hierarchical series of organisms each dependent on the next as a source of food.
What is a food chain?
