Plant Biology
Plant part where photosynthesis occurs.
Leaves
Type of plant that Mendel used in his famous experiment.
Pea
Cell division resulting in the same number of chromosomes
Mitosis
Elements of a test that remain constant throughout an entire experiment
Controlled variables
An individual's genetic makeup.
Genotype
Non-vascular, seedless plant group that is the major flora in inhospitable environments.
Bryophytes
Strings of these form proteins
Amino acids
Organelle that modifies proteins made by ribosomes
Rough endoplasmic reticulum
Each step along the food chain
Trophic level
Programmed cell death
Plant tissue that transports sugars and proteins.
Phloem
Silent mutation
1. All living things are composed of one or more cells.
2. The cell is the basic unit of life.
3. New cells arise from existing cells.
Organ system that plays a role in growth, metabolism, and sexual reproduction; uses hormones as chemical messengers
Endocrine system
Small openings in leaves through which gas exchange occurs
Stomata
Plants living in hot environments have modified leaves (ex. cactus spines) that prevent this.
Water loss
A process that occurs during prophase I of meiosis where genetic material is exchanged between homologous chromosomes, resulting in genetic diversity.
Recombination
Chemical messengers in cell communication
Ligands
Exoskeleton
The principle that states A=T and C=G in a strand of DNA
Chargaff's rule
Group of plants with exposed (naked) seeds
Gymnosperms
Zygosity that's always used in a test cross
Homozygous recessive
Mitosis will not progress past this point if the cell is not the proper size, does not have the correct protein reserves, or has any replicated DNA that is damaged.
G2 checkpoint
The process to restore an ecosystem after an environmental disturbance.
Secondary succession
Adenine and guanine are this kind of nucleotide
Purines
