BASICS
The tiny structure inside a cell that has a specific job/function for the cell.
What is an organelle?
The outer part of a plant cell that gives it its support.
What is the cell wall?
This is the structure that creates proteins for the cell.
What is a ribosome?
This organelle is responsible for packaging and transporting proteins within the cell.
What is the Golgi apparatus?
Who is the scientist who discovered the existence of cells in the 1600s?
Who is Hooke?
The basic structure of all living things.
What is a cell?
This is the control center of the cell.
What is the nucleus?
What structure is absent in prokaryotic cells? Think bacteria.
What is the nucelus?
This long, whip-like structure helps some cells move through their environment.
What is the flagella?
A cell has the following: mitochondria, a nucleus, chloroplasts, and a cell wall. Will it be found in
a. the bark of a tree
b. a leaf
c. bacteria
What is a leaf?
List the three parts of the cell theory?
What is
-all living things are composed of cells
-cells are the basic units of structure and function in living things
-all cells are produced from other cells?
Which part of the cell protects the nucleus and allows materials to pass in and out through the pores.
What is the nuclear envelope?
This structure takes in energy and water and produces glucose (energy) for the cell.
What is the chloroplast?
This protein framework inside the cell helps maintain its shape and assists in movement.
What is the cytoskeleton?
Explain what "selectively permeable" means.
What is a barrier that allows certain molecules or ions to pass through while preventing others from passing?
Put the five levels of organization in order from largest to smallest.
What is organism, organ system, organ, tissue, and cell?
This structure that breaks down food (glucose) to create energy for the cell.
What is the mitochondria?
These tiny finger-like projections on the surface of some cells increase the surface area to help with absorption.
What are microvilli?
What is store water & food, waste products, and help provide structural support in a plant cell?
Define osmosis.
What is the diffusion of water molecules through a selectively permeable membrane? This is PASSIVE.
What are the 4 characteristics of living things?
What is organization, response to stimuli, growth & development, and reproduction?
How is the rough ER structurally different from the smooth ER?
What is the the rough ER contains proteins?
This is the reason why the inner membrane of the mitochondria is so important to its function.
What is it is folded up to create more surface area so it can make more energy?
What does the lysosome break down? List 3 things.
What is worn-out cell parts, food, & viruses?
This type of microscope uses beams of electrons to see very small details inside cells.
What is an electron microscope?
