Lesson 1
cycle of growth, development, and division that most cells go through
What is the cell cycle?
unicellular organism with a membrane-bound nucleus and many organelles; examples are algae and amoeba
What is a eukaryote?
period during the cell cycle of a cell's growth and development
What is interphase?
groups of similar types of cells that work together to carry out specific tasks
What are tissues?
the DNA is copied during this stage of interphase
What is S stage?
number of stages within interphase
What is 3?
unspecialized cells in areas of a plant
What are meristems?
2 identical chromosomes that make up a duplicated chromosome
What are sister chromatids?
What are organs?
___________ disappears during prophase of mitosis
What is a nucleolus?
number of stages within mitosis
What is 4?
4 types of animal tissue
What are muscle, connective, nervous, and epithelial?
sister chromatids are held together by this structure
What is a centromere?
groups of different organs that work together to complete a series of tasks
What are organ systems?
type of tissue that causes movement in animals
What is muscle tissue?
longer phase of the cell cycle
What is interphase?
2 organ systems of a plant
What are the shoot and root system?
the cytoplasm and its contents divide
What is cytokinesis?
process by which cells become different types of cells
4 results of cell division
What are reproduction, repair, replacement, and growth?
the phase of mitosis where chromosomes line up in the middle of the cell
What is metaphase?
type of plant tissue where photosynthesis takes place
What is ground tissue?
2 new cells that result from mitosis and cytokinesis
What are daughter cells?
unspecialized cells that are able to develop into many different cell types within an animal
What are stem cells?
phase in mitosis when the spindle fibers break down and the nuclear membrane forms
What is telophase?
