Unit 1
The process by which organisms change over time in response to their changing environment
What is evolution?
Prokaryotic cell structure which is described as a rigid outer barrier which functions in protection, structural support and prevents excess water movement
What is the cell wall?
short, hair-like extensions found in a eukaryotic cell which aids in cell movement
What are cilia?
thin, waxy outer layer found in plants which prevents water loss
What is the cuticle?
Type of vertebrate tissue which is composed of cells tightly fused together
What is epithelial tissue?
The introduction of a new species
What is speciation?
Prokaryotic cell structure that is a long cellular extension which aids in cell movement
Type of fungal hyphae without cross walls between cells
What are coenocytic hyphae?
The part of a seed that serves as food storage to provide nutrients that allow the embryo to develop when the seed germinates
What is the endosperm
What is muscle tissue?
Type of speciation where two or more groups differentiate into separate species even as they occupy the same geographical area
What is sympatric speciation?
region of the prokaryotic cytoplasm which contains DNA
What is the nucleoid?
Material found in the cell wall of fungi
What is chitin?
small pores in plants that allow for gas exchange
What are stomata?
Type of vertebrate tissue which functions to receive and process information?
What is nervous tissue?
variations of a gene
What is an allele?
Viral component that is described as an outer layer, similar to cell membrane as it is acquired from host cell
What is the envelope?
The form of nutrition utilized by fungi where enzymes are secreted into their environment to break down materials and then absorb the break down products into their cells
What is saprophytic nutrition?
The form of metabolism used by plants
What is photosynthesis/autotrophic pathway?
What is epithelial tissue?
Type of reproductive isolation which prevent the fusion of gametes
What is pre-zygotic isolation?
Protein coat of a virus
“animal-like” protists as they engulf their food and break it down internally
What are phagotrophs?
What is the gametophyte?
Type of vertebrate tissue which is composed of cells embedded within a protein matrix
What is connective tissue?
