Cell Organelles
The organelle responsible for protecting and supporting plant cells as well as provide them their signature shape.
What is... cell wall
The scientist who named the empty spaces in cork "cells."
Who is... Robert Hooke
The selectively permeable organelle responsible for active and passive transport (into and out of the cell).
What is...cell membrane
The regular sequence of growth and division that all cells undergo (3 stages).
What is... the cell cycle.
The cell type that has no membrane-bound organelles or a nucleus.
What is... prokaryotic cell.
The organelle responsible for transporting proteins and other materials INSIDE of the cell. Can be found with or without ribosomes attached.
What is... ER (endoplasmic reticulum)
The scientist who discovered that all living cells must come from pre-existing cells.
Who is... Rudolph Virchow
The amount of something in a given area.
What is... concentration.
The stage of the cell cycle where DNA is replicated and the cell is growing to prepare for division.
What is... interphase.
The cell type that includes typical plant and animal cells.
What is... eukaryotic cell.
The organelle that stores the DNA and controls all of the cell's daily functions.
What is... nucleus
The scientist who observed living microorganisms in pond water with a microscope and named them "animacules".
Who is...Anton Van Leeuwenhoek.
The movement of molecules against a concentration gradient (low to high) across a cell membrane with the use of ATP energy.
What is... active transport.
The stage of mitosis where the spindle fibers retract, causing the chromatids to be pulled apart to opposite ends of the cell.
What is... Anaphase.
The levels of organization in a multicellular organism from simplest to most complex.
What is... cell, tissue, organ, organ system, organism.
The organelle that breaks down molecules and releases energy.
What is... mitochondrion (mitochondria)
The scientist who discovered that all plants are composed of cells.
Who is... Mattias Schleiden
The movement of any molecule from an area of high concentration to low concentration without the use of energy.
What is... diffusion
The stage of mitosis where the nucleus begins to dissolve and the DNA condenses into chromatids that become paired chromosomes.
What is... prophase.
The scientific variable that is changed or manipulated by the experimenter. Only one is typically changed at a time.
What is... independent variable.
The organelle responsible for storing back up water for plant cells in case water becomes less accessible.
What is... vacuole (large, central vacuole)
The scientist who stated that all animals are composed of cells.
Who is... Theodor Schwann
The diffusion of water molecules across a selectively permeable membrane from high concentration to low concentration without the use of energy.
What is... osmosis.
The steps of mitosis in order.
What is... prophase, metaphase, anaphase, telophase.
The normal, unchanged conditions used for comparison to experimental results.
What is... control.
