The basic building blocks of life
What are cells?
This fills the space inside a cell. It is semi-fluid and is composed of water and dissolved materials.
What is cytoplasm?
This organelle provides the cell with the energy it needs to perform its functions and activities.
What is the mitochondria?
This is what all living things are made of
What are cells?
All living cells come from this
What are other living cells or pre-existing
This organelle directs cell processes by providing DNA instructions. It is surrounded by its own membrane and is covered with pores.
What is the nucleus?
This structure controls what comes in and leaves the cell
What is the cell membrane?
Schleiden and Schwann realized that animals and plants have cells. This led to the development of what part of the cell theory?
What is all living things are made of cells?
The number of living things that come from cells
What is all of them?
This is the chemical inside of the nucleus
What is DNA?
Which organelle do prokaryotes NOT have that eukaryotes do?
What is a nucleus?
According to the Cell Theory, cells are the what?
What is the basic unit of life/structure/function?
Cells got their name because of this
What is they looked like little rooms?
This organelle is a series of interconnected passageways that proteins use to travel through the cell. Can be abbreviated with 2 letters
What is the endoplasmic reticulum?
These follow DNA instructions to make proteins. They are free-floating or may be found attached to the ER.
What are ribosomes?
The main 5 chemical compounds in all cells
What are water, carbohydrates, proteins, lipids, and nucleic acids
the equation for cellular respiration
oxygen + glucose ------> water + carbon dioxide + ENERGY
Autotrophs contain these structures to do photosynthesis
What are chloroplasts?
The 2 differences between plant and animal cells are:
1. Plant cells have cell walls. 2. Plant cells have chloroplasts
